What is rate of change?
The rate of change of a function is the rate at which the output values change over the input value.
The rate of change of a function is one degree less than the actual function.
The volume of a cube is :
V = s³
The rate of change of volume V with respect to length a will be :
dV/ds = d(s³ )/ds
= 3s²
This means that, a cubic function will have a quadratic rate of change
Hence, The roc of the volume of a cube with respect to the length of its side s is 3s².

If a production line produces 50 mouse traps every 30 minutes over the course of a 10-hour work day with a half hour break for lunch how many mouse traps are made in a day
Answers
100 traps/ 1 hr times 9.5 hrs = 950
10 hrs - half hr break (30 minutes) = 9.5 hrs of work
so if it is 100 mousetraps per hr...and the hrs worked are 9.5 hrs.....then the number of mousetraps produced are : 9.5 * 100 = 950 mouse traps <==
A miner descended 1500 feet into a mine. While in the mine, he then rose 1200 feet and then descended 850 feet. What was the miner's net gain or loss in altitude?

Then add the numbers.
A miner descended 1500 feet into a mine.
-1500 ft
he then rose 1200 feet
+1200 ft
then descended 850 feet
-850 ft
Now add the three numbers:
-1500 ft + 1200 ft + (- 850 ft) = -1150 ft
Since the sum is a negative number, that means
he had a net loss in altitude of 1150 ft.

Mary having her living room and bedroom painted. Interior Designs USA charges $60.00 to evaluate the space plus $35.00 per hour of labor. Splash of Color charges $55.00 per hour with no initial fee. Which of the following are true? Select all that apply.
If it takes 7 hours to paint the two rooms, Interior Designs USA will charge the least.
Splash of Color will always charge the least.
If it takes more than 5 hours to paint the rooms, Splash of Color will be more cost effective.
If it takes 10 hours to paint the rooms, Splash of Color will charge $200 more than Interior Designs USA.
If it takes 3 hours to paint the rooms, both companies will charge the same amount.
Answers
Answer:
The correct statements are 1, 3, and 5.
Explanation:
Let's calculate the total cost for each company based on the given information:
For Interior Designs USA:
- Evaluation fee: $60.00
- Labor cost per hour: $35.00
- Total labor cost for 7 hours: $35.00/hour × 7 hours = $245.00
- Total cost = Evaluation fee + Total labor cost = $60.00 + $245.00 = $305.00
For Splash of Color:
- Labor cost per hour: $55.00
- Total labor cost for 7 hours: $55.00/hour × 7 hours = $385.00
Now, let's analyze the statements:
1. If it takes 7 hours to paint the two rooms, Interior Designs USA will charge the least. - True. ($305.00 < $385.00)
2. Splash of Color will always charge the least. - False. In this case, Interior Designs USA charges less for 7 hours of work.
3. If it takes more than 5 hours to paint the rooms, Splash of Color will be more cost effective. - True. As we've seen, Splash of Color charges $55.00 per hour, while Interior Designs USA charges $35.00 per hour plus an initial fee.
4. If it takes 10 hours to paint the rooms, Splash of Color will charge $200 more than Interior Designs USA. - False. Let's calculate:
- Interior Designs USA: $60.00 (evaluation fee) + $35.00/hour × 10 hours = $60.00 + $350.00 = $410.00
- Splash of Color: $55.00/hour × 10 hours = $550.00
Splash of Color charges $550.00 - $410.00 = $140.00 more, not $200. Therefore, this statement is false.
5. If it takes 3 hours to paint the rooms, both companies will charge the same amount. - False. Let's calculate:
- Interior Designs USA: $60.00 (evaluation fee) + $35.00/hour × 3 hours = $60.00 + $105.00 = $165.00
- Splash of Color: $55.00/hour × 3 hours = $165.00
They both charge $165.00, so this statement is true.
So, the correct statements are 1, 3, and 5.

Raffle tickets are being sold for a fundraiser. The function a(n) relates the amount of money raised to the number of tickets sold, n.
It takes as input the number of tickets sold and returns as output the amount of money raised.
a(n) = 3n – 15
Which equation represents the inverse function n(a), which takes the money raised as input and returns the number of tickets sold as output?
Answers
Answer:
For apex it is N(a)= [tex]\frac{a+15}{3}[/tex]
To find the inverse function, solve the equation a = 3n - 15 for n. The inverse function is n(a) = (a + 15) / 3.
Explanation:To find the inverse function, we need to solve the equation n(a) = 3n - 15 for n.
Step 1: Replace n(a) with a: a = 3n - 15
Step 2: Solve for n.
Add 15 to both sides of the equation.a + 15 = 3nDivide both sides of the equation by 3.(a + 15) / 3 = nTherefore, the inverse function is n(a) = (a + 15) / 3.
Solve P=2D+2C for D
Answers
Answer: D = (P - 2C)/2
Step-by-step explanation:
We want to solve P= 2D + 2C for D
This means "isolate D in one side of the equation"
The first step is subtracting 2C in the both sides of the equation:
P - 2C = 2D + 2C - 2C = 2D
P - 2C = 2D
Now, we want to take of the multiplication that is acting on D, so we divide in both sides by 2:
(P - 2C)/2 = (2D)/2 = D
Now we have D isolated, and this is:
D = (P - 2C)/2

Which equation has the same solution as 4-2(x-5)-x-19
Answers
The equation 3x - 4 = 2x + 7 has the same solution as 4 - 2(x - 5) = x - 19, with both solutions yielding x = 11.
Let's solve the equation step-by-step: 4 - 2(x - 5) = x - 19
First, expand the left side:4 - 2x + 10 = x - 19Combine like terms:
14 - 2x = x - 19Move all terms involving x to one side:
14 = 3x - 19Move constant terms to the other side:
33 = 3xSolve for x:
x = 11
Now, let's compare this solution to other given equations:
2(x + 5) = -82x + 10 = -8
2x = -18
x = -9 (Not a match)3(x - 3) = 9
3x - 9 = 9
3x = 18
x = 6 (Not a match)x + 2 = 2x - 3
2 = x - 3
x = 5 (Not a match)3x - 4 = 2x + 7
3x - 2x = 7 + 4
x = 11 (Match)
The equation with the same solution as 4 - 2(x - 5) = x - 19 is 3x - 4 = 2x + 7.
Complete question: Which equation has the same solution as 4 - 2(x - 5) = x - 19?

Answers
The probability that a selected consumer is 35–55 years old or likes crunchicles is 0.5.
Explanation:To determine the probability that the selected consumer is 35–55 years old or likes crunchicles, we need to add the probabilities of these two events happening individually and subtract the probability of both events happening. Let's assume the probability of a randomly selected consumer being 35–55 years old is 0.4 and the probability of a randomly selected consumer liking crunchicles is 0.3. The probability of a randomly selected consumer being both 35–55 years old and liking crunchicles is 0.2. Therefore, the probability that the selected consumer is 35–55 years old or likes crunchicles is:
P(35-55 or crunchicles) = P(35-55) + P(crunchicles) - P(35-55 and crunchicles)
= 0.4 + 0.3 - 0.2 = 0.5

an air traffic controller is tracking two planes. To start, playing a is at an altitude of 2814 ft and plan B is just taking off. Plan a is gaining altitude at 30.5 feet per second in playing day is gaining altitude at 80.75 feet per second. How many seconds will pass before the planes are on the same altitude
Answers
The initial altitude is the 'y-intercept'.
The rate of elevation is the slope.
Plane A: y = 30.5x + 2814
Plane B: y = 80.75x
The planes will be at same altitude when the y values are equal.
80.75x = 30.5x + 2814
Solve equation for 'x'.
80.75x - 30.5x = 2814
50.25x = 2814
x = (2814/50.25) = 56

It will take 56 seconds before planes are at same altitude.

56 seconds will pass.

A point estimate is a single value used to estimate an unknown parameter. The point estimate of the difference between the mean annual premium in Pennsylvania and the national mean can be calculated by taking the difference between the two means.
Explanation:A point estimate is a single value that is used to estimate an unknown parameter of a population. In this case, the point estimate of the difference between the mean annual premium in Pennsylvania and the national mean can be calculated by taking the difference between the two means.
