The following equation denotes the correlation between the duration and output of an activity: A = kT
How to explain the equationIt should be noted that A represents the amount of production, T is the period of working on the task, and k consists of a constant ratio.
Therefore, it can be conclusively stated that the culminating yield is in direct correlation to the amount of effort contributed, as denoted by the factor of proportionality k, thus producing a linear relationship when displayed upon a graph.

Selena took a pizza out of the oven, and it started to cool to room temperature (68°F). She will serve the pizza when it reaches 130°F. She took the pizza out at 5:00 P.M. Use regression to find when she can serve it.
Selena can serve the pizza at around 6:40 P.M.
How to explain the regressionThe regression line should have the equation y = -1.7x + 300, where y is the temperature, x is the time in minutes since the pizza was taken out of the oven, -1.7 is the slope of the line, and 300 is the y-intercept.
Set y (the temperature) to 130°F, and solve for x (the time).
130 = -1.7x + 300
-170 = -1.7x
x ≈ 100
According to the regression model, the pizza will reach 130°F after about 100 minutes after it was taken out of the oven. Therefore, Selena can serve the pizza at around:

(10 points) During a recent oil spill in the gulf, the radius of the spill was increasing at a rate of 10 feet per second. How fast is the circular area of the spill increasing at the moment that the radius is 80 feet? dA = dt __________
The solution is, the two dimensions will be 2121.32 by 1414.2.
Here, we have,
let X and Y be the two dimensions.
Area will be X times Y.
XY = 3000000
Y = 3000000 / X
Perimeter = 2x + 3y
substituting the values:
Perimeter = 2x + 3*3000000 / x
= 2x + 9000000 / x
so, we get,
2 = 9000000 / x^2
x^2 = 9000000 / 2 = 4500000
x = sqrt(4,500,000)
= 2121.32
= 1000 sqrt (4.5)
y = 3000000 / 2121.32
= 1414.2
= 1000 sqrt(2)
so the dimensions will be 2121.32 by 1414.2 .

Use the given circumference to find the surface area of the spherical object. a pincushion with C = 24 cm
Answer:
approximately 183.4 square centimeters.
Step-by-step explanation:
We can use the formula for the circumference of a sphere, which is:
C = 2πr
where C is the circumference and r is the radius.
We know that the circumference of the pincushion is 24 cm. We can use this to find the radius:
C = 2πr
24 = 2πr
r = 24/(2π)
r ≈ 3.82 cm
Now that we know the radius, we can use the formula for the surface area of a sphere, which is:
A = 4πr^2
Substituting the value we found for the radius, we get:
A = 4π(3.82)^2
A ≈ 183.4 cm^2
Therefore, the surface area of the pincushion is approximately 183.4 square centimeters.

Salton City has a lower altitude because -60.96 meters is greater than -38.1
Salton City has a lower altitude because -60.96 meters is less than -38.1 meters.
Option C is the correct answer.
We have,
The altitude of Bombay Beach is -60.96 meters.
The altitude of Salton City is -38.1 meters.
Altitude is the height of a location above sea level, and a negative value indicates that the location is below sea level.
Therefore, we can see that Salton City has a higher altitude than Bombay Beach because -38.1 meters is a higher altitude than -60.96 meters.
Thus,
Salton City has a lower altitude because -60.96 meters is less than -38.1 meters.

You want to purchase a new bike that costs $125.99. To save for the bike, you mow your neighbor's yard for $40 each week. How much money will you have left over if you buy the bike after saving for 4 weeks?
Answer: $34.01
Step-by-step explanation:
To get the answer, we must first add up the entire amount of money saved after four weeks of mowing the neighbor's lawn, then subtract the bike's price.
Since we get $40 a week, after 4 weeks we will have saved the following:
40 × 4 = 160
We will therefore have $160 to spend on the bike. The bike costs $125.99, so we will have the following amount of money after purchasing the bike:
160 - 125.99 = 34.01
Therefore, after purchasing the bike, we will have $34.01 leftover.
for a new customer top golf charges $10 for a player card and $2 per hour.
The cost for a new customer to rent a bay for 6 hours at Top Golf is $22, which includes a $10 player card fee and a $12 bay rental fee at $2 per hour.
Let's let "x" be the total cost for a new customer to rent a bay for 6 hours.
We know that there is a flat fee of $10 for the player card, and then an additional $2 per hour for the bay rental.
So, the equation for the cost "x" can be written as
x = 10 + 2(6)
The expression 2(6) represents the cost of the bay rental for 6 hours. We can simplify the expression by multiplying 2 and 6, which gives us
x = 10 + 12
Now, we can combine like terms to find the final cost
x = 22
Therefore, the cost for a new customer to rent a bay for 6 hours at Top Golf is $22.

Put the quadratic into vertex form
The vertex form of the quadratic function f(x) = 2x^2 + 8x + 7 is f(x) = 2(x + 2)^2 - 25.
How to find the vertex formTake a look at the quadratic function:
f(x) = 2x^2 + 8x + 7
In this situation, a = 2 and b = 8, yielding:
f(x) = 2(x^2 + 4x) + 7
It shtbe noted that to determine the value to add and subtract, multiply (b/2a)2 by (8/2(2))2 = 42 = 16. Inside the parenthesis, we add and subtract 16:
f(x) = 2(x^2 + 4x + 16 - 16) + 7
The expression inside the parenthesis can now be written as a perfect square:
f(x) = 2((x + 2)^2 - 16) + 7
Finally, the phrase is simplified by spreading the 2:
f(x) = 2(x + 2)^2 - 32 + 7

Piedmont Hotels is an all-equity company. Its stock has a beta of 1.29. The market risk premium is 7.2 percent and the risk-free rate is 3.0 percent. The company is considering a project that it considers riskier than its current operations so it wants to apply an adjustment of 2.2 percent to the project's discount rate. What should the firm set as the required rate of return for the project?
The firm set 14.49% as the required rate of return for the project.
What is the required rate of return for Piedmont Hotels' riskier project?We will first calculate the Project's discount rate which can we calculated using the formula that:
= Rf rate + Beta*risk premium
= 3.0% + 1.29*7.2%
= 3.0% + 0.09288
= 0.12288
= 12.29%
The required rate of return for the project will be:
= Project's discount rate + Adjustment rate
