find the equation of the line that is perpendicular to y=3x and passes through the point (4,-2)

Answer:

The height of the building is 153.664 meter.

Step-by-step explanation:

Consider the provided function.

[tex]s(t) = 4.9t^2 + v_0 t + s_0[/tex]

Here t represents the time v₀ represents the initial velocity, s₀ represents the initial height and s(t) represents the height after t seconds.

It is given that the splash is seen 5.6 seconds after the stone is dropped.

That means after 5.6 seconds height s(t) = 0, Also the initial velocity of the stone is 0.

Substitute respective values in the above function.

[tex]0 = 4.9(5.6)^2 +5.6(0)+ s_0[/tex]

[tex]0 = 4.9(31.36)+ s_0[/tex]

[tex]s_0=-153.664[/tex]

As height can't be a negative number so the value of s₀ is 153.664.

Hence, the height of the building is 153.664 meter.

Answer:

a) The demand function is

[tex]q(p) = -4 p + 107[/tex]

b) The nightly revenue is

[tex] R(p) = -4 p^2 + 107 p [/tex]

c) The profit function is

[tex]P(p) = -4 p^2 + 133.75 p - 939 [/tex]

d) The entrance fees that allow Swing Haven to break even are between 10.03 and 23.41 dollars per guest.

Step-by-step explanation:

a) Lets find the slope s of the demand:

[tex] s = \frac{79-43}{7-16} = \frac{36}{-9} = -4 [/tex]

Since the demand takes the value 79 in 7, then

[tex]q(p) = -4 (p-7) + 79 = -4 p + 107[/tex]

b) The nightly revenue can be found by multiplying q by p

[tex]R(p) = p*q(p) = p*( -4 p + 107) = -4 p^2 + 107 p[/tex]

c) The profit function is obtained from substracting the const function C(p) from the revenue function R(p)

[tex]P(p) = R(p) - C(p) = p*q(p) = -4 p^2 + 107 p - (-26.75p + 939) = \\\\-4 p^2 + 133.75 p - 939[/tex]

d) Lets find out the zeros and positive interval of P. Since P is a quadratic function with negative main coefficient, then it should have a maximum at the vertex, and between the roots (if any), the function should be positive. Therefore, we just need to find the zeros of P

[tex]r_1, r_2 = \frac{-133.75 \,^+_-\, \sqrt{133.75^2-4*(-4)*(-939)} }{-8} = \frac{-133.75 \,^+_-\, 53.526}{-8} \\r_1 = 10.03\\r_2 = 23.41[/tex]

Therefore, the entrance fees that allow Swing Haven to break even are between 10.03 and 23.41 dollars per guest.

We found the linear demand equation as q(p) = -4p + 107. The nightly revenue R(p) is R(p) = -4p^2 + 107p, and the profit P(p) is P(p) = -4p^2 + 133.75p - 939. Setting the profit equal to zero, we found the club breaks even at entrance fees $5.32 and $44.31.

In this question, we're asked to formulate linear demand, revenue, and profit equations, and find the entrance fees for break even. First, let's find the linear demand equation.

To obtain this demand equation, we can use the two given points ($7, 79) and ($16, 43) and find the slope (rate of change) equals (43-79) / (16-7) = -4. Hence the demand equation will be q(p) = -4p + b. To find b, substitute one of the points into the equation, for example ($7, 79), we get b=107, hence q(p) = -4p + 107.

Next, let's find the nightly revenue R (p), which is simply the product of the entrance fee and the number of guests, hence R(p) = p * q(p) = p (-4p + 107) = -4p^2 + 107p.

 The profit P(p) is the difference between revenue and costs, hence P(p) = R(p) - C(p) = -4p^2 + 107p - (-26.75p + 939) = -4p^2 + 133.75p - 939.

Finally, for Swing Haven to break even, the profit must be zero. By setting P(p) = 0 and solving the equation -4p^2 + 133.75p - 939 = 0, we get the two solutions p = 5.3216 and p = 44.3031, or roughly $5.32 and $44.31.

Answer: the plant is 6 1/4 inches above the​ ground.

Step-by-step explanation:

In her garden Pam plants the seed 5 and one fourth inches below the ground. Converting 5 and one fourth inches to improper fraction, it becomes 21/4 inches.

After one month the tomato plant has grown a total of 11 and one half inches. Converting 11 and one half inches to improper fraction, it becomes 23/2 inches.

The height of the the plant above the​ ground would be

23/2 - 21/4 = (46 - 21)/4 = 25/4

Converting to mixed fraction, it becomes

Answer:

The probability that Meena wins is 21/25

Step-by-step explanation:

In order for Meena to win, she needs to win the next turn or the following one, otherwise, she loses. The probability for that is equal to substract from 1 the probability of the complementary event: bob wins in the next 2 turns. Since each turn is independent from the other, we can obtain the probability of Bob winning the next 2 turns by taking the square of the probability of him winning on one turn, hence it is

[tex] {\frac{2}{5}}^2 = \frac{4}{25} [/tex]

Thus, the probability for Meena to win is 1-4/25 = 21/25.

Meena only needs one more point to win, and with a ⅘ or 60% probability in her favor for the next turn, she will win the game.

The question asks for the probability that Meena will win a game where she is currently ahead 9 to 6, and the game is won by the first person to reach 10 points. In each turn, there is a ⅗ chance that Bob will get 2 points and Meena will lose 1 point, and a ⅘ chance that Meena will get 2 points and Bob will lose 1 point.

To find the probability of Meena winning, we only need to look at the next round because Meena is already at 9 points and she needs only 1 point to win. Two scenarios can occur:

Bob gets 2 points, and Meena loses 1 point. This outcome is not possible because Meena cannot have 8 points; she's already at 9 points. So, this situation doesn't count.

Meena gets 2 points (which will put her at or above 10 points) and Bob loses 1 point. This is the winning scenario for Meena. The probability of this happening is ⅘ or 0.6 (since only this outcome will end the game with Meena as the winner).

Therefore, the probability that Meena will win on the next turn (and win the game) is 0.6 or 60%

Answer: b. 70%

Step-by-step explanation:

Given : Nik logs the following hours meeting with clients (c) or doing other work (o) :

Mon: 6 c, 4 o

Tue: 8 c, 2 o

Wed: 9 c, 1 o

Thu: 7 c, 3 o

Fri: Off

The number of hours Nik spend with clients on Thursday = 7 [Number of corresponding to c is 7 in the table]

Total hours he spend in work on Thursday =  7+3 = 10

The percent of time Nik spent with clients on Thursday :

[tex]\dfrac{\text{Number of hours he spent with clients}}{\text{Total works he work on Thursday}}\times100\\\\=\dfrac{7}{10}\times100=7\times10\%=70\%[/tex]

Hence, the Nik spent 70% of his time with clients on Thursday.

The variable x is found to equal 3. Substituting x=3 into the expressions for JK and KL, both are found to equal 13. The entire line segment JL is then found to equal 26.

In this mathematics problem, we are given that K is the midpoint of JL. This implies that the segments JK and KL are of equal length, thus JK=KL.

So, we can set the two given expressions equal to each other: 2x+7=4x+1. Solving this equation for x, we get that x=3.

Substituting x=3 into the expressions for JK and KL: JK=2x+7=2(3)+7=13, and KL=4x+1=4(3)+1=13.

To find JL, we simply add JK and KL together, since JKL is a line segment with K being the midpoint. Hence, JL=JK+KL=13+13=26.

Step-by-step explanation:

The total number of possible integers when any number is selected is 10 (i.e from 0 - 9). When four number integers are selected, the total number of sample sample will be;

                                   10 × 10 × 10 × 10 = 10,000

The sample space = 10,000

To know the possible ways of selecting the given four digits, we will use permutation.

                                 [tex]^{n}P_{r} = \frac{n!}{(n-r)!}[/tex]

To get the probability,

but 0! = 1

                                     [tex]^{4}P_{4} = 4![/tex]

Answer:

option 1

Step-by-step explanation:

first we have to find the slopes of the lines

D(1, -2)     E(3, 4)

y = m*x + b

m1: slope

m1 = (y2-y1) / (x2-x1)

m1 = (4 - (-2)) / (3 - 1)

m1 = 4+2 / 3-1

m1 = 6 / 2

m1 = 3

we do the same with the other 2 points

D(-1, 2)     E(4, 0)

y = m*x + b

m2: slope

m2 = (y2-y1) / (x2-x1)

m2 = (0 - 2) / (4 - (-1))

m2 = -2 / 4 + 1

m2 = -2 / 5

m1 = 3        m2 = -2/5

for 2 lines to be perpendicular it must be met

m1 * m2 = -1

we check if they are perpendicular

3 * -2/5 = -1

-6/5 = -1   <-- no perpendicular

Part 1: The function that models the height of the basketball is [tex]\( h(t) = -16t^2 + 15t + 6.5 \).[/tex]

Part 2: The basketball hits the ground after approximately 0.97 seconds.

Part 3: The basketball reaches its maximum height at approximately 0.47 seconds.

Part 4: The maximum height of the basketball is approximately 11.39 feet.

Part 1: To model the height of the basketball, we use the given function [tex]\( h(t) = -16t^2 + v0t + h0 \)[/tex] with the initial velocity [tex]\( v0 = 15 \)[/tex] ft/sec and the initial height [tex]\( h0 = 6.5 \)[/tex] feet. Plugging in these values, we get the function:

[tex]\[ h(t) = -16t^2 + 15t + 6.5 \][/tex]

Part 2: To find the time it takes for the basketball to hit the ground, we set the height function equal to zero and solve for [tex]\( t \)[/tex]:

[tex]\[ -16t^2 + 15t + 6.5 = 0 \][/tex]

Using the quadratic formula [tex]\( t = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \),[/tex]where [tex]\( a = -16 \), \( b = 15 \)[/tex], and [tex]\( c = 6.5 \)[/tex], we get two solutions. We discard the negative solution because time cannot be negative, and we round the positive solution to the nearest hundredth:

[tex]\[ t = \frac{-15 \pm \sqrt{15^2 - 4(-16)(6.5)}}{2(-16)} \] \[ t = \frac{-15 \pm \sqrt{225 + 416}}{-32} \] \[ t = \frac{-15 \pm \sqrt{641}}{-32} \] \[ t \approx \frac{-15 + 25.31}{-32} \] \[ t \approx 0.97 \text{ seconds} \][/tex]

Part 3: To find when the basketball reaches its maximum height, we need to find the vertex of the parabola. The time coordinate of the vertex of a parabola [tex]\( ax^2 + bx + c \)[/tex] is given by [tex]\( t = -\frac{b}{2a} \)[/tex]. For our function, [tex]\( a = -16 \)[/tex]and [tex]\( b = 15 \)[/tex], so:

[tex]\[ t = -\frac{15}{2(-16)} \] \[ t = \frac{15}{32} \] \[ t \approx 0.47 \text{ seconds} \][/tex]

Part 4: To find the maximum height, we substitute the time at which the maximum height is reached back into the height function:

[tex]\[ h(0.47) = -16(0.47)^2 + 15(0.47) + 6.5 \] \[ h(0.47) \approx -16(0.2209) + 7.05 + 6.5 \] \[ h(0.47) \approx -3.5344 + 7.05 + 6.5 \] \[ h(0.47) \approx 11.39 \text{ feet} \][/tex]

Therefore, the basketball reaches a maximum height of approximately 11.39 feet after approximately 0.47 seconds.

Step-by-step explanation:

Given:

Cost Price for producing 'd' dog lashes = [tex]9000+3.2d[/tex]

Revenue Generated from selling 'd' dog lashes = [tex]d(15-0.00005d)[/tex]

We need to find the profit earned from producing and selling 'd' dog lashes.

Solution:

Now we know that;

profit earned from producing and selling 'd' dog lashes can be calculated by Subtracting Cost Price for producing 'd' dog lashes from Revenue Generated from selling 'd' dog lashes.

framing in equation form we get;

Profit earned = [tex]d(15-0.00005d)-(9000+3.2d)[/tex]

Now Applying Distributive property we get;

Profit earned = [tex]15d-0.00005d^2-9000-3.2d[/tex]

Now Combining like terms we get;

Profit earned = [tex]-0.00005d^2+15d-3.2d-9000[/tex]

Profit earned = [tex]-0.00005d^2+11.8d-9000[/tex]

Hence  Profit earned from producing and selling 'd' dog lashes is [tex]-0.00005d^2+11.8d-9000[/tex].

Final answer:

The polynomial representing the profit from producing and selling d dog leashes is -0.00005d² + 11.8d - 9000, calculated by subtracting the cost (9000 + 3.2d) from the revenue (d(15 - 0.00005d)).

Explanation:

The student's question relates to finding the polynomial expression that represents the profit earned from producing and selling d dog leashes. Profit is calculated by subtracting the cost from the revenue. The cost polynomial is given as 9000 + 3.2d, and the revenue polynomial is d(15 - 0.00005d).

To find the profit, we subtract the cost from the revenue:

Profit = Revenue - Cost

Profit = (d(15 - 0.00005d)) - (9000 + 3.2d)

Profit = 15d - 0.00005d² - 9000 - 3.2d

Profit = -0.00005d² + (15 - 3.2)d - 9000

Profit = -0.00005d² + 11.8d - 9000

Therefore, the correct polynomial that represents the profit is -0.00005d² + 11.8d - 9000.

Answer:

40/13 hours

Step-by-step explanation:

Let 1 represent the room being painted.

1/5 would represent 1/5 of a room painted in 1 hour.

1/8 would represent 1/8 of a room being painted in 1 hour

But they are are working together so

(1/5)x + (1/8)x = 1

The lowest common denominator is 5 * 8 = 40

[(1/5)x * 40 + (1/8)x * 40] = 1

8x + 5x = 40

13x = 40

x = 40/13

x = 3.077 hours

But you want a fraction as your answer so it is 3 1/13 or 40/13

You should notice that 3.077 is smaller than the lowest amount of time both of them use. That always happens with these questions.

Final answer:

Rachel and Barbara would take ⅜shy hours to paint the living room together, as they have a combined work rate of 0.325 room/hour calculated from their rates of 1 room per 5 hours and 1 room per 8 hours, respectively.

Explanation:

To find out how many hours it would take Rachel and Barbara to paint the living room together, we can use the concept of work rate. Rachel's work rate is ⅑or (1 room per 5 hours), and Barbara's work rate is ⅑or (1 room per 8 hours). To find their combined work rate, we add their rates together.

Rachel's rate: ⅑or (1 room/5 hours) = 0.2 room/hour
Barbara's rate: ⅑or (1 room/8 hours) = 0.125 room/hour
Combined rate: 0.2 + 0.125 = 0.325 room/hour

To find out how long it takes them to paint the room together, we can set up the equation: 1 room = (0.325 room/hour) × (hours). Solving for 'hours' gives us:

Hours = ⅑or / 0.325
Hours = ⅑or / (⅜shy / 1)
Hours = ⅜shy × 1
Hours = ⅜shy
Therefore, it would take them ⅜shy hours to complete the painting together.

Step-by-step explanation:

From the question stated let us recall the following statement.

The number of cities the tourist wants to visit is =8

Now,

If the route is selected randomly, what is the probability that the cities she visits are in alphabetical order.

Therefore,

The probability that she visits the cities in alphabetical order = 1/8!

There are 8! = 40320 ways in which these cities can be visited

P(Visiting in alphabetical order) = 1/40320 = 0.00002480

Step-by-step explanation:

Triangle WXY is a right angle triangle.

From the given right angle triangle,

WX represents the hypotenuse of the right angle triangle.

With m∠W as the reference angle,

WY represents the adjacent side of the right angle triangle.

XY represents the opposite side of the right angle triangle.

To determine m∠W, we would apply

the cosine trigonometric ratio.

Cos θ = adjacent side/hypotenuse. Therefore,

Cos W = 5/7 = 0.7143

W = 44.1° to the nearest tenth.

The differential equation provided is transformed to M(x,y) dx + N(x,y) dy = 0 with M(x,y) = [tex]-4x^4 - 3y[/tex]and N(x,y) = 3x + [tex]2y^4[/tex], setting the stage for verifying its exactness through partial differentiation.

To address the student's query about finding a function F(x,y) whose differential fits the given differential equation, we'll first transform the differential equation dy/dx =[tex](-4x4-3y)/(3x+2y4)[/tex] into the form M(x,y) dx + N(x,y) dy = 0.

This transformation requires us to regard the equation as a differential one, implying:

This representation simplifies the process of checking for exactness, which necessitates partial differentiation and comparison of ∂M/∂y and ∂N/∂x.

Should these partial derivatives be equal, the differential is exact, enabling the determination of the function F(x, y) through integration.

Combining 2s and −4s gives an equivalent expression of −2s.

We need to combine the like terms. Like terms are terms that have the same variable raised to the same power. In this case, both terms involve the variable "s."

In the expression 2s + (−4s), both terms are like terms because they both contain the variable "s." The coefficients are 2 and −4.

To combine like terms, you simply add or subtract their coefficients while keeping the variable the same:

Coefficient of the first term: 2

Coefficient of the second term: −4

Now, perform the arithmetic operation:

2 + (−4) = −2

Final answer:

The cost for two pounds of gummy bunnies is $2.66, with the unit rate being $1.33 per pound after rounding to two decimal places.

Explanation:

To determine how much two pounds of gummy bunnies will cost at Joan's candy emporium, we first need to calculate the unit rate of the gummy bunnies that are selling for $4.00 per three pounds. The unit rate is found by dividing the total cost by the number of pounds:

Unit Rate = Total Cost / Number of Pounds

Unit Rate = $4.00 / 3 pounds = $1.33 per pound (rounded to two decimal places)

Now that we have the unit rate, we can determine the cost for two pounds of gummy bunnies:

Cost for Two Pounds = Unit Rate x Number of Pounds

Cost for Two Pounds = $1.33 per pound x 2 pounds = $2.66 (rounded to two decimal places)

Answer:

The submarine will be located 1350ft below sea level or (-1350ft)

Step-by-step explanation:

First we must find the distance traveled

[tex](\frac{300}{1} )(\frac{4.5}{1})[/tex]

From this, we are able to calculate that traveled distance of the submarine.

300 x 4.5 = 1350

1350 + 0 (sea level) = 1350

Therefore the distance traveled by the submarine is 1350ft

Answer:

-1350 ft
