Question 40 and it about adding and subtracting polynomials

Hello!

The answer is 20/60 simplest form is 1/3

To get 20/60 you must multiply the Numerator by Numerator (4*5) and Denominator by Denominator (5*12). Your answer will be 20/60.

To get 1/3 you must simplify a number that can go into 20 and 60 (which is 10). Divide 20/10 and 60/10 and get 2/6. Simplify 2/6 by 2 and get 1/3.

Answer:

m=3/4

Step-by-step explanation:

Slope is equal to the change in y over the change in x, or rise over run.

m=change in y/change in x

The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).

m=y2−y1/x2−x1

Substitute in the values of x and y into the equation to find the slope.

m=9−(3)/5−(−3)

Simplify.

m=3/4

The slope of the line passing through the points (-3,3) and (5,9) is 3/4

The formula for calculating the slope of a line is expressed as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\[/tex]

Given the coordinate (-3,3) and (5,9), substitute the coordinates into the formula as shown below;

[tex]m=\frac{9-3}{5-(-3)}\\m=\frac{6}{5+3} \\m=\frac{6}{8}\\m=\frac{3}{4}[/tex]

Hence the slope of the line passing through the points (-3,3) and (5,9) is 3/4

Answer: B) 1 second

Step-by-step explanation:

plug 16 (final height) into the equation given:

16=-16t^2+8t+24, and solve for t.

x will equal -1/2 or 1

disregard the negative because you can’t have time.

To reach 16 feet above the water, you would reach that height after approximately 1/2 second. Option C

To find when you would reach 16 feet above the water, set the function h(t) equal to 16 and solve for t:

-16t2 + 8t + 24 = 16

Combine like terms to get:

-16t2 + 8t + 8 = 0

Now, you can use the quadratic formula to solve for t:

t = (-b ± √(b2 - 4ac)) / (2a)

Plug in the values of a, b, and c from the equation:

t = (-8 ± √(82 - 4(-16)(8))) / (2(-16))

Simplify the expression inside the square root and solve for t to get the answer:

t ≈ 1/2 second

Option C

Step-by-step explanation:

Answer:

2880 km

Step-by-step explanation:

(distance) = (rate)*(time).

Here we have:

(distance traveled) = (720 km/hr)(4 hrs) = 2880 km

Answer:

The correct answer is B. $ 29,555.50

Step-by-step explanation:

Let's calculate A, using the formula provided, this way:

A = P * [(1 + r)ⁿ - 1]/r * (1 + r)ⁿ, where:

P is the month payment = 725

r is the monthly interest rate = 0.0825/12 = 0.006875

n is  the the number of months to pay = 4 * 12 = 48

Replacing with the values we know, we have:

A = P * [(1 + r)ⁿ - 1]/r * (1 + r)ⁿ

A = 725 * [(1 +0.006875 )⁴⁸ - 1]/0.006875 * (1 +0.006875 )⁴⁸

A = 725 * 0.38939833/0.006875 * 1.38939833

A = 282.313789/0.009552114

A = 29,555.50

The correct answer is B. $ 29,555.50

The correct option is B. [tex]\$29555.50[/tex]. The maximum loan Chase can afford, while making monthly payments of [tex]\$725[/tex] for [tex]4[/tex] years at an [tex]8.25\%[/tex] annual interest rate.

Given:

Monthly payment [tex]\( P = $725 \)[/tex]

Annual interest rate [tex]\( r = 8.25\% \)[/tex] or [tex]\( 0.0825 \)[/tex] as a decimal

Number of payments per year [tex]\( n = 12 \)[/tex] (since monthly payments)

Number of years [tex]\( t = 4 \)[/tex]

The formula to calculate the present value [tex]\( A \)[/tex] of the loan is:

[tex]\[ A = P \times \frac{1 - (1 + \frac{r}{n})^{-nt}}{\frac{r}{n}} \][/tex]

Now, substitute the given values

[tex]\[ A = 725 \times \frac{1 - (1 + \frac{0.0825}{12})^{-12 \times 4}}{\frac{0.0825}{12}} \][/tex]

First, calculate [tex]\( \frac{r}{n} \)[/tex]

[tex]\[ \frac{0.0825}{12} = 0.006875 \][/tex]

Next, calculate [tex]\( (1 + \frac{r}{n})^{-nt} \)[/tex]

[tex]\[ (1 + 0.006875)^{-48} = 0.7221 \][/tex]

Now substitute these values into the formula for [tex]\( A \)[/tex]

[tex]\[ A = 725 \times \frac{1 - 0.7221}{0.006875} \][/tex]

[tex]\[ A = 725 \times \frac{0.2779}{0.006875} \][/tex]

[tex]\[ A = 725 \times 40.4218 \][/tex]

[tex]\[ A = 29555.50 \][/tex]

Step-by-step explanation:

Step-by-step explanation:

[tex]5 \: hours \: = 5 \times 60 = 300 \: min \\ minutes \: per \: episode = \frac{300}{6} \\ = 50 \\ [/tex]

Hence, each episode lasted for 50 minutes on an average.

On average, each episode of the TV series lasts 50 minutes, calculated by converting the total viewing time of five hours to 300 minutes and dividing that by the number of episodes, which is six.

To calculate the average duration of an episode, we need to convert the total time of all episodes from hours to minutes and then divide by the number of episodes.

There are 60 minutes in one hour, so five hours equates to 300 minutes (5 hours × 60 minutes/hour = 300 minutes). With six episodes in total, we divide the total minutes by the number of episodes to find the average length of one episode.

300 minutes / 6 episodes = 50 minutes per episode.

Therefore, on average, each episode of the TV series lasts 50 minutes.

Step-by-step explanation:

Let A be the point at which the graph y=x²+3x-18

intersect the x-axis

As the graph intersects x-axis it's coordinate will be (x,0)

putting the value of y =0

x²+3x-18=0

x²+6x-3x-18=0

x(x+6)-3(x+6)=0

(x+6)(x-3)=0

x=-6, or,x=3

The point A maybe (-6,0) or (3,0)

50 seconds

Recall the equation

d=rt

Distance = rates times time.

We have a single distance, 400m

We have two different rates 1 1/3 m/s and 1.6 m/s

Let's calculate the time for each rate

t = d/r

t = 400/(1 1/3) = 300 seconds

t = 400/1.6 = 250 seconds

By increasing his average speed, Alex will reduce his time by

300-250 = 50 seconds.

Answer:

The answer is 90

The value of the 10!/(10 - 2)! is 90 after simplification of the factorial option (C) 90 is correct.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have given an expression:

10!/(10 - 2)!

The sign '!' represents the factorial of the number.

As we know,

If factorial of any number can be evaluated:

n! = n(n - 1)(n - 2)(n - 3)(n - 4).......1

10! = 10×9×8×7×6×5×4×3×2×1

or

10! = 90(8!)

(10 - 2)! = 8!

= 90(8!)/(8)!

90

8! is canceled out from the numerator and denominator

Thus, the value of the 10!/(10 - 2)! is 90 after simplification of the factorial option (C) 90 is correct.

#SPJ5

Answer:

A) Linear

Step-by-step explanation:

For a linear relation, there will be a constant rate of change

For an exponential relationship, there will be a multiplicative rate of change.

For x-values, there is a constant difference of

[tex]d = 4 - - 3 = 11 - 4 = 18 - 11 = 7[/tex]

For the y-values, there is a constant difference of

[tex]b = 1 - - 3 = 5 - 1 = 9 - 5 = 4[/tex]

The rate of change of the function represented by the table is

[tex]m = \frac{change \: in \: y}{change \: in \: x} = \frac{4}{7} [/tex]

The equation can be derived as:

[tex]y + 3 = \frac{4}{7} (x + 3)[/tex]

This is a linear relationship

Solution:

Given that,

[tex]y = 4.50x[/tex]

We have to find the constant of proportionality in the equation

We know that,

When y varies directly with x, then

[tex]y \propto x\\\\y = kx ---- eqn\ 1[/tex]

Where, "k" is constant of proportionality

From given,

y = 4.50x

Compare the above equation with eqn 1,

Thus, constant of proportionality in the equation y = 4.50x is 4.50

Answer: x = -14/5

Step-by-step explanation: We shall begin by expanding the brackets for both sides of the equation

-2/3 (x + 2) = 1/6 (x + 6)

(-2x/3) -4/3 = (x/6) + 1

By collecting like terms we now have

(-2x/3) - (x/6) = 1 + 4/3

(-4x - x)/6 = 7/3

-5x/6 = 7/3

By cross multiplication we now have

-5x (3) = 7 (6)

-15x = 42

x = -(42/15) {simplify further by dividing the RHS by 3}

x = -14/5

Therefore x equals, minus fourteen over five (-14/5)

AB = [tex]4\sqrt{3}[/tex]

Step-by-step explanation:

30-60-90 theorem, usually x is used to explain but I will use y since x is in your problem, just substitute any variable for y

in a 30 -60 -90 triangle

the length opposite the 30 degrees is y

the length opposite the 60 degrees is y[tex]\sqrt{3}[/tex]

the length opposite the 90 degrees is 2y

since y[tex]\sqrt{3}[/tex] = 6

y = 6/[tex]\sqrt{3}[/tex]

rationalizing the denominator

[tex]\frac{6}{\sqrt{3} } *\frac{\sqrt{3}}{\sqrt{3}}[/tex] = [tex]\frac{6\sqrt{3} }{3} = 2\sqrt{3}[/tex]

if y = [tex]2\sqrt{3}[/tex], 2y = [tex]4\sqrt{3}[/tex]

To calculate the total cost for a 660 feet fence by Company 2, subtract the initial 550 feet covered by the flat fee from the total length, multiply the additional feet by the per-foot cost, and add the flat fee to get the final cost, which is $7790.

The student is asking about calculating the total cost for installing fencing, which involves initial fees and additional per unit costs. In this case, Company 2 charges a flat fee for the first 550 feet of fence and then an additional fee for each foot beyond that.

To find the total cost when Company 2 installs a fence of 660 feet, we first calculate the number of feet beyond the initial 550 feet. This is 660 - 550 = 110 feet. Then, we multiply the additional feet by the cost per additional foot: 110 feet x $29/foot = $3190.

Lastly, we add the initial flat fee of $4600 to the cost for the additional feet to get the total cost: $4600 + $3190 = $7790.
