Since there is an x^2 term therefore this equation is of a parabola

By taking LCM and then cross multiplying it.

6y=x^2-9x+26

6y=x^2-9x+(9/2)^2+23/4

6y-23/4=(x-9/2)^2

we see that this is of the form

X^2=4AY

(x-9/2)^2=4(3y/2-23/16)

Answer:

[tex]f(x) =- \sqrt{x-1}+3[/tex]

Step-by-step explanation:

This looks like a square root function [tex]f(x) = \sqrt{x}[/tex]  but symmetric with respect to the x axis and shifted to the right for 1 and up for 3:

Lets take  [tex]f(x) = \sqrt{x}[/tex] . The function symmetric with respect to the x axis would be [tex]-f(x)[/tex], so now we have:

                                                [tex]f(x) = -\sqrt{x}[/tex]

Lets take [tex]f(x) = -\sqrt{x}[/tex] and shift it up for y = 3. Now we have:

                                               [tex]f(x) =- \sqrt{x}+3[/tex]

Lets take [tex]f(x) = -\sqrt{x}+3[/tex] and shift it right for x = 1. That means that instead of x we will have x-1:

                                            [tex]f(x) =- \sqrt{x-1}+3[/tex]

Answer: $13,114

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = 9000

r = 3.8% = 3.8/100 = 0.038

n = 2 because it was compounded 2 times in a year.

t = 10 years

Therefore,.

A = 9000(1+0.038/2)^2 × 10

A = 9000(1+0.019)^20

A = 9000(1.019)^20

A = $13114

The final amount that Jenny's investment would be worth of at the end of 10 years is given by: Option B:  $13114 approx.

If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:

[tex]CI = P(1 +\dfrac{R}{100})^T - P[/tex]

The final amount becomes:

[tex]A = CI + P\\A = P(1 +\dfrac{R}{100})^T[/tex]

For this case, we are given that:

Thus, the final amount at the end of 10 years is given by:

[tex]A = P(1 +\dfrac{1.9}{100})^T\\\\A = 9000(1 + \dfrac{1.9}{100})^{20} = 9000(1.019)^{20} \approx 13114 \text{\: \: (in dollars)}[/tex]

Thus, the final amount that Jenny's investment would be worth of at the end of 10 years is given by: Option B:  $13114 approx.

Part 1:

Replace "v0" in the given equation with the given velocity of 15 ft/sec:

y = -16t^2 + 15t +6.5

Part 2:

Now set the equation to 0 which would be when the basketball hits the ground:

-16t^2 +15t +6.5 = 0

A quadratic equation is solved using the formula:

t = -b +/- sqrt(b^2-4ac)/2a

Using the given equation: a = -16, b = 15 and c = 6.5

Replace the values and solve:

t = -(15)+/- sqrt(15^2 -4(-16)(6.5))/2(-16)

This solves to get both -0.32 and 1.26 seconds.

The time has to be a positive value so t = 1.26 seconds.

Part3:

Using the quadratic form at^2 + bt + c

The maximum is found using t = -b/2a = -15/2(-16) = = 0.47 seconds

The maximum height would be at 0.47 seconds

Part 4:

Answer:

19 wrong answers.

Step-by-step explanation:

Given:

Sahil got 28 questions right.

Angelina got 7 more wrong answers than Sahil.

There where 40 questions on the test.

Question asked:

How many answers did Angelina get wrong on the math test ?

Solution:

Total questions on the test = 40

Number of right answers, Sahil got = 28

Number of wrong answers, Sahil got = 40 - 28 = 12

As Angelina got 7 more wrong answers than Sahil,

Number of wrong answers, Sahil got = 12

Then, number of wrong answers, Angelina got = 12 + 7 = 19

Therefore, 19 answers did Angelina get wrong on the math test out of 40.

Angelina got 35 wrong answers on the math test.

To find the number of wrong answers Angelina got on the math test, we need to know how many questions she got right. Since Sahil got 28 questions right and there were 40 questions on the test, we can subtract Sahil's score from the total number of questions to find Angelina's score. Sahil got 28 questions right, so Angelina would have gotten 40 - 28 = 12 questions right. And since Angelina got 7 more wrong answers than Sahil, we can subtract Sahil's wrong answers from Angelina's total wrong answers to find the specific number. If Sahil got 12 questions right, then he must have gotten 40 - 12 = 28 questions wrong. And since Angelina got 7 more wrong answers than Sahil, we can add 7 to Sahil's wrong answers to find Angelina's total wrong answers. Therefore, Angelina got 28 + 7 = 35 wrong answers on the math test.

Answer:

There are 18 Sedans in the dealership shop.

Step-by-step explanation:

Let x represent the number of Sedans in the dealership shop.

Let y represent the number of SUV's in the dealership shop.

If there are a combined 24 sedans and SUVs, it means that

x + y = 24 - - - - - - - - - - - -1

At a car dealership, there are three times as many sedans as SUVs. This means that

x = 3y

Substituting x = 3y into equation 1, it becomes

3y + y = 24

4y = 24

y = 24/4 = 6

x = 3y = 6 × 3

x = 18

The coordinates of A'  after rotation  of 270 counterclockwise and then shifted down 3 units are (2, 4).

To find the coordinates of point A' after a 270-degree counterclockwise rotation around the origin and then shifting down 3 units, we first perform the rotation.

A 270-degree counterclockwise rotation is equivalent to a 90-degree clockwise rotation. So, when we rotate point A(-7, -2) 90 degrees clockwise, we swap the coordinates and change the sign of the former x-coordinate, which gives us the new point A''(2, 7). Next, we shift A'' down 3 units, which means we subtract 3 from the y-coordinate, resulting in A'(2, 4).

The required equation in a standard form that represents the number of rooms Martin has left to clean (y) after x hours is 4x + 7y = 56.

To write the equation in a standard form that represents the number of rooms Martin has left to clean (y) after x hours, we can use the given information that there are 4 rooms left to clean after 7 hours.

Let's start with the point-slope form of a linear equation:

y - y₁ = m(x - x₁)

We have the point (x₁, y₁) = (7, 4), which represents the number of rooms left after 7 hours.

Substituting the values into the point-slope form, we get:

y - 4 = m(x - 7)

Now, we need to find the slope (m) of the line.

The slope of a line can be determined by the change in y divided by the change in x. In this case, the change in y is -4 (4 rooms left to clean) and the change in x is 7 hours.

m = Δy / Δx = -4 / 7

Now, let's substitute the value of m into the equation:

y - 4 = (-4/7)(x - 7)

To eliminate fractions, we can multiply through by 7:

7y - 28 = -4(x - 7)

7y - 28 = -4x + 28

4x + 7y = 56

So, the equation in a standard form that represents the number of rooms Martin has left to clean (y) after x hours is 4x + 7y = 56.

Final answer:

To express the relationship between the number of rooms left to clean and the hours spent cleaning in a linear equation, we use the slope of -4/7 and a y-intercept of 4, assuming 4 rooms are cleaned in 7 hours. This leads to the slope-intercept form y = -4/7x + 4. Multiplying by 7 and rearranging gives us the standard form 4x + 7y = 28.

Explanation:

To find the equation of the line that represents the number of rooms, y, Martin has left to clean after x hours, we start with the information that 4 rooms take 7 hours to clean. This means that every hour, a fraction of the total rooms are cleaned. To express this situation as a linear equation, we can use the slope-intercept form, which is y = mx + b. In this context, the slope (m) will be negative since the number of rooms left to clean decreases over time, and b is the y-intercept representing the initial number of rooms before any cleaning has started. Since there are 4 rooms to begin with and it takes 7 hours to clean all, the slope is -4/7 (the change in rooms left per hour).

The equation in slope-intercept form is y = -4/7x + 4. To convert this to standard form, we multiply the entire equation by 7 to eliminate the fraction: 7y = -4x + 28. Then we add 4x to both sides of the equation to get: 4x + 7y = 28. This is the equation in standard form, representing the number of rooms left (y) after x hours of cleaning.

Substituting the value of x in the above equation, we have

(5×3 + 9)/2 = 24/2 = 12 verified

x = 3

(c) x/4 = 9/6

Multiplying both sides by 4, we have

x/4×4 = 9/6×4 = 6

x = 6

(6/4 = 9/6 = 3/2 verified

(d) 5/x = 20/8

Inverting both equations, we have

x/5 = 8/20

Multiplying both sides by 20 we have x/5 × 20 = 8/20 × 20 or 4x = 8 and x = 2

Answer:

There were 180 voters for blue color.

Step-by-step explanation:

Let the total number of voters be 'x'.

Given:

Number of Voters for blue color = [tex]\frac{5}{8}x[/tex]

Number of Voters for green color = [tex]\frac{5}{9}(x-\frac58x)=\frac59x(1-\frac58)[/tex]

Now we will use LCM to make the denominator common we get;

Number of Voters for green color = [tex]\frac59x(\frac88-\frac58)=\frac59x(\frac{8-5}{9})=\frac59x(\frac38)=\frac{15x}{72}[/tex]

Number of Voters for red color = 48

We need to find the number of voters for blue color.

Solution:

Now we can say that;

total number of voters is equal to sum of Number of Voters for blue color, Number of Voters for green color and Number of Voters for red color.

framing in equation form we get;

[tex]x=\frac58x+\frac{15x}{72}+48[/tex]

Combining like terms we get;

[tex]x-\frac58x-\frac{15x}{72} = 48[/tex]

Now we will make denominators common using LCM we get;

[tex]\frac{72x}{72}-\frac{5x\times9}{8\times9}-\frac{15x\times1}{72\times 1} = 48\\\\\frac{72x}{72}-\frac{45x}{72}-\frac{15x}{72} = 48[/tex]

Now denominators are common so we will solve the numerators we get;

[tex]\frac{72x-45x-15x}{72}=48\\\\\frac{12x}{72}=48\\\\\frac{x}{6}=48[/tex]

Now multiplying both side by 6 we get;

[tex]\frac{1}{6}x\times6=48\times6\\\\x = 288[/tex]

Number of voters for blue color = [tex]\frac{5}{8}x=\frac{5}{8}\times 288= 180[/tex]

Hence There were 180 voters for blue color.

Answer:

At 7 hours from the visit telling the joke, everyone in town would have heard of it

Step-by-step explanation:

Exponential Grow

This is a good example of exponential growth, where the speed at which a rumor is spread out depends on the actual number of persons who already know it.

The visitor told the mayor a new joke at 10:00 am.

Total people who heard the joke=1

This person tells the joke to 3 people in one hour, so at 11:00 am, 1+3=4 persons heard the joke

Total people who heard the joke=4

Those persons take one hour to tell the joke to every 3 persons each. Thus at 11:00  

4 + 4*3 = 16 persons heard the joke. This succession grows very quickly. At 12:00

16 + 16*3 = 64 persons heard the joke

We can note the number of persons hearing the joke is an even power of 2, that is

[tex]2^0=1[/tex]

[tex]2^2=4[/tex]

[tex]2^4=16[/tex]

[tex]2^6=64[/tex]

We can predict the result for each hour since the exponent is double the number of hours passed since the joke started to spread. The number of persons who have heard the joke after t hours is

[tex]N=2^{2t}[/tex]

We can iterate until we find the value of t so that

[tex]2^{2t}<9800[/tex]

Let's better find the limit value of t

[tex]2^{2t}=9800[/tex]

Taking logarithms

[tex]log(2^{2t})=log9800[/tex]

[tex]2tlog(2)=log(9800)[/tex]

Thus

[tex]\displaystyle t=\frac{log(9800)}{2log 2}[/tex]

[tex]t=6.6[/tex]

So at 7 hours from the visit telling the joke (between 16:00 and 17:00), everyone in town would know it

Answer:

Step-by-step explanation:

Let t = flying time in seconds for each plane

Descending rate = 40 ft/s

Ascending rate = 60 ft/s

Descending height, hd= 19200 - 40t

Ascending height, ha = 60t

Equating hd = ha, therefore:

60t = 19200-40t

60t + 40t = 19200

100t = 19200

t = 19200/100

t = 192 seconds

h = 19200 - 192(40)

h = 19200 - 7680

= 11,520 ft.

After 192 seconds, the two airplanes will be at the same height, which is 11,520 feet.

To find the time it takes for the two airplanes to be at the same height, we need to set up an equation based on their rates of ascent and descent. Let's assume the height of the descending airplane is given by h1 and the height of the ascending airplane is given by h2. The descending airplane is descending at a rate of 40 feet per second, so its height after t seconds can be represented by the equation h1 = 19,200 - 40t. The ascending airplane is ascending at a rate of 60 feet per second, so its height after t seconds can be represented by the equation h2 = 60t. To find the time at which the two airplanes are at the same height, we can set h1 equal to h2 and solve for t: 19,200 - 40t = 60t. Simplifying this equation, we get 100t = 19,200, so t = 192 seconds. Therefore, after 192 seconds, the two airplanes will be at the same height.

To find the height at which the two airplanes are at, we can substitute the value of t into either the equation for h1 or h2. Let's use the equation for h1: h1 = 19,200 - 40(192) = 19,200 - 7,680 = 11,520 feet. Therefore, after 192 seconds, the two airplanes will be at a height of 11,520 feet.

Answer: the system of equations are

a + c = 150

7.75a + 10.25b = 1470

Step-by-step explanation:

Let a represent the number of adult tickets that were sold.

Let c represent the number of child tickets that were sold.

The celluloid cinema sold 150 tickets to a movie. Some of these were child tickets and the rest were adult tickets. This means that

a + c = 150 - - - - - - - - - - - - - -1

A child ticket cost $7.75 and an adult ticket cost $10.25. If the cinema sold $1470 worth of tickets, it means that

7.75a + 10.25b = 1470 - - - - - - - - -2

The question can be answered by creating two linear equations, one representing the total number of tickets (a + c = 150) and the other representing the total earnings from the ticket sales (10.25a + 7.75c = 1470). Solving this system of equations will yield the number of adult and child tickets sold.

This problem can be solved using a system of linear equations, where one equation represents the total number of tickets sold and the other equation represents the total dollar value of the tickets sold.

The first equation is formed from the total number of tickets, which is the sum of adult tickets and child tickets: a + c = 150

The second equation is formed from the total cost of the tickets, where $10.25, the cost of an adult ticket, is multiplied by the number of adult tickets, and $7.75, the cost of a child ticket, is multiplied by the number of child tickets. This sum should be the total earnings from the ticket sales: 10.25a + 7.75c = 1470

Therefore, the system of equations to solve this problem is a + c = 150 and 10.25a + 7.75c = 1470.

Answer: he open the account 9 years ago.

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the amount deposited.

P represents the principal or amount deposited.

R represents interest rate

T represents the time for which the amount deposited was left in the account.

From the information given,

P = 400

R = 7.5%

I = 670 - 400 = $270

Therefore,

270 = (400 × 7.5 × T)/100 = 30T

T = 270/30

T = 9 years

Answer: the shipping and handling fee is 8 percent of the cost of the order.

Step-by-step explanation:

Shipping and handling fee of $35 is charged to all furniture orders over $250.

If the order is $437.50, it means that there would be a handing and shipping fee of $35 because the price of the order is above $250.

The percentage of the original price of the order that is the shipping and handling fee would be

35/437.5 × 100 = 0.08 × 100

= 8%

Final answer:

To find the percent that the shipping and handling fee is of the total order, divide the fee by the order amount and multiply by 100. For an order of $437.50 with a fee of $35, the shipping fee is 8% of the total order.

Explanation:

The question asks us to determine what percent the shipping and handling fee is of the total furniture order.

To calculate this percentage, we can use the formula:

Percentage = (Part / Whole)  imes 100

In this case:

Now, we insert the values into the formula:

Percentage = ($35 / $437.50)  imes 100

Percentage = 0.08  imes 100

Percentage = 8%

Therefore, the shipping and handling fee is 8% of the total order.

Answer:

Step-by-step explanation:

Let x represent the number of pounds of soap that she makes and eventually sells.

She intially spent $72 to purchase soap-making equipment, and the materials for each pound of soap cost $7. This means that the total cost of making x pounds of soap would be

7x + 72

Lisa sells the soap for $10 per pound. This means that her revenue for x pounds of soap would be

10 × x = 10x

If she eventually sells enough soap to cover the cost of the equipment, then

7x + 72 = 10x

10x - 7x = 72

3x = 72

x = 72/3 = 24

She would need to sell make and sell 24 soaps.

The cost would be

72 + 7 × 24 = $240

The total sales would be

10 × 24 = $240

Answer:

  d.  about 9 years​

Step-by-step explanation:

There is a "rule of thumb" for doubling time* that says the product of the percentage rate of change per year and the doubling time in years is about 72. Here, that means the doubling time is about ...

  72/8 = 9 . . . . years

_____

You can write the exponential equation ...

  multiplier = (1 +.08)^n

and solve for multiplier = 2:

  2 = 1.08^n

  log(2) = n·log(1.08) . . . . . take logs

  log(2)/log(1.08) = n . . . . . divide by the coefficient of n

  9.00647 ≈ n

It will take about 9 years for the participation to double.

_____

* The farther away from 8% the rate of change is, or the more times per year it is compounded, the less accurate is the "rule of 72." When compounding is continuous, the "rule of 72" becomes the "rule of 69.4". For this problem, answer choices are sufficiently far apart that the rule of thumb is adequate for making a correct choice.

Answer:

C

Step-by-step explanation:

In the first instance, he wanted buying euros in exchange for his dollars. He had $540 and wanted to buy euros. The conversion factor here is that for every 1 euro, he pays $1.80

Now at the second instance, he wanted buying dollars with his left over euros. This means for every 1 euro, he gets $1.4

Since, he is having 40 euros, the total amount in dollars he would get will be 40 * $1.4 = $56

Answer:

[tex]d = 670,616,629h \ mi[/tex]

Step-by-step explanation:

Given:

Speed of the light = 670,616,629 mi\hr

We need to find the direct variation equation represents given situation.

Solution:

Speed is defined as the ratio of distance and time. So, the equation of the speed is as follows:

[tex]Speed = \frac{Distance}{Time}[/tex]

And also written as.

[tex]S = \frac{d}{h}[/tex]

Now, we write the above equation for distance.

[tex]d = S\times h[/tex] ------------(1)

Where:

d = distance travel by object.

S = speed of the object.

h = Total time taken

Substitute S = 670,616,629 mi\hr in equation 1.

[tex]d = 670,616,629h \ mi[/tex]

Therefore, direct variation equation to represents the given situation

[tex]d = 670,616,629h \ mi[/tex]
