Inverse of function f(x) is f⁻¹(x) = x³/125 - 7
What is inverse function?An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by 'f' or 'F', then the inverse function is denoted by f⁻¹ or F⁻¹.
Given function,
f(x) = 5∛(x + 7)
f⁻¹(x) = 5∛(f(x) + 7)
Cubing both sides
x³ = 5³(f(x) + 7)
x³ = 125 (f(x) + 7)
f(x) + 7 = x³/125
f(x) = x³/125 - 7
Hence, f⁻¹(x) = x³/125 - 7 is inverse of function f(x).

A car rental agency charges $250 per week plus $0.10 per mile to rent a car.
a. Write an equation that expresses the weekly cost to rent the car, y, in terms of the number of miles driven during the week, x.
b. How many miles did you drive during the week if the weekly cost to rent the car was $260?
Answer:
a. 250+0.10x=y
b. 250+0.10x=260
-250. -250
———————————-
0 + 0.10x = 10
——— ——-
0.10 0.10
—————————————-
X = 100
( you drove 100 miles )
Step-by-step explanation:
In question A, basically you already have a base of 250 and you add 0.10, multiplying it with x, which is the number of miles, equals to the total amount. So the answer for that question is : 250+0.10x = y. For question B, you just had to substitute the y for 260, and solve for x ( subtract 250 from both sides, divide by 0.10 on both sides, and you get x = 100. So the answer for that question is you drove 100 miles.
hope this helped =)
The cost of renting a car can be formulated as y = 250 + 0.10x, with y representing the total cost and x the distance travelled. If the total cost was $260, then 100 miles were driven.
Explanation:The car rental agency's charge can be represented as a linear equation with a fixed cost ($250/week) plus a variable cost ($0.10/mile). This can be represented algebraically as: y = 250 + 0.10x, where y is the total weekly cost and x signifies the number of miles driven.
To find out how many miles (x) were driven for a total cost of $260, substitute y with 260 in the equation and solve for x:
260 = 250 + 0.10xSubtract 250 from both sides: 10 = 0.10xDivide by 0.10 to solve for x: x = 100Therefore, if the weekly cost to rent the car was $260, you drove 100 miles.

b) $84000 is the total money that will be put into the account.
c) The total interest earned is obtained as $272796.54.
What is Compound Interest?
The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.
a) Figure out the period interest rate, i.
Use the formula: i=r/m, where r is the nominal interest rate and m is the number of compounding periods.
If the bank pays 7% compounded monthly, that means that the nominal annual interest rate is 7.0% and the monthly period interest rate is 7/12 = 0.58%.
The principal amount A = $200
The number of times interest applied per time period n = 35 × 12 = 420
Now, use the uniform series compound-amount factor to find the future value.
The equation is -
F = A [((1 + i)^n) - 1] / i
where F is the future value, A is the annuity amount, i is the period interest rate.
Substitute the values into the equation -
F = 200 [((1 + 0.0058)^420) - 1] / 0.0058
F = 200 [((1.0058)^420) - 1] / 0.0058
F = 200 (11.3471 - 1) / 0.0058
F = 200 (10.3471) / 0.0058
F = 200 × 1783.9827
F = 356796.54
Therefore, the amount will be $356796.54 after 35 years.
b) The total money put in the account will be -
Total amount = The principal amount × The number of times interest applied per time period
Total amount = A × n
Substitute the values into the equation -
Total amount = 200 × 420
Total amount = 84000
Therefore, the total amount is $84000.
c) The total interest earned will be -
Total Interest = The future amount - The total money put in the account
Total Interest = F - The total money put in the account
Substitute the values into the equation -
Total Interest = 356796.54 - 84000
Total Interest = 272796.54
Therefore, the total interest is $272796.54.

A deli is trying out new labels for their cylindrical-shaped wheels of cheese. The label covers the entire wheel except the circular top and bottom.
If the wheel has a radius of 22 centimeters and a height of 16 centimeters, how many square centimeters of the wheel does the label cover? (Approximate using pi equals 22 over 7)
A. 15,488 over 7 square centimeters
B. 36,784 over 7 square centimeters
C. 1,936 over 7 square centimeters
D. 340,736 over 7 square centimeters
Answer: The real answer is 15,488 over 7 square centimeters.
Step-by-step explanation:
For this question, you need to use the formula for surface area of a cylinder: SA = 2πr^2 + 2πrh
Since the label DOES NOT cover the bases, you do not need to do the first part of the formula (2πr^2) because that part is finding the area of the bases. We are only looking for how many square centimeters the label IS covering.
2πrh
So times the radius by 2.
22 * 2 = 44
Now times 44 by the height
44 * 16 = 704
And finally, times 704 by 22/7
22/7 * 704 = 15,488 over 7 square centimeters
So 15,488 over 7 square centimeters is the answer.
You might get it in decimal form (something like this number 2,212.5714285) but if you divide 15,488 by 7 you will get the same decimal.

Last year at a certain high school, there were 95 boys on the honor roll and 64 girls on the honor roll. This year, the number of boys on the honor roll increased by 20% and the number of girls on the honor roll increased by 25%. By what percentage did the total number of students on the honor roll increase? Round your answer to the nearest tenth (if necessary).
Answer:
1.9 percent
Step-by-step explanation:
95 boys + 64 girls = 159 total honor roll students
To quickly find percentages of numbers, think of the current number as 100%, or 1.00. Then, go from there to find the number to multiply to get the percentage you need.
For example, a 25% decrease in the number of girls means the new number will be 75% of the old number, so we multiply the number of girls by 0.75 to get the new number of girls. 64*0.75 = 48.
Same with the boys, 95 boys is 100%, but this year the number increased by 20%, so we need to find 120% of the number, so we multiply it by 1.20. 95*1.20 = 114
To answer this question, we need to know by what percent the total number of honor students increased by, so we need to know the new total number. 48+114 = 162
To find out what percent 162 is out of 159, we divide them. 162 / 159 = 1.0188, or 101.9 percent if you round to the nearest tenth. So, the number of students increased by 1.9%.

Find the Profit value
if the supply cost of each electric bicycle is £950, and the company decides to set the price less than £1300, then we can repeat the above process to find the optimal price and profit.
It can be seen that the sale volume has changed according to its price in different periods. The values have been reported in the following table. This company is going to launch a new product and the price needs to be decided based on the market analysis. Determine the appropriate price for the newly developed electric bicycle with the aim of maximizing the company’s profit. The demand for new products has a direct relationship with its price.
Table 1- Demands of an electric bicycle based on a price level according to previous experiences
Price (£) Demand
1150 415
1185 405
1210 390
1235 380
1260 345
1285 302

1435 222
1460 216
1485 214
1510 210
1540 200
The main objective of the company is to maximize profit regarding to the new product. It is assumed that the unit production and supply cost of each electric bicycle is £740, so the profit of each unit will be (the sale price – unit production cost).
Determine the optimal demand
Compute the optimal profit.
Interpret the results.
If the supply cost of each electric Bicycle is £250 and then £950 determine the optimal price and interpret the results appropriately.
Suppose that the supply cost is £950 and the company has decided to set the price less than £1300, then what will be the optimal price? Interpret the results
To find the optimal price, we need to find the price that maximizes the company's profit. Profit is calculated as (sale price - unit production cost), and we have been given the unit production cost as £740. So, the profit function can be written as:
Profit = (sale price - £740) * demand
Using the data in the table, we can plot the demand as a function of price and then calculate the profit for each price level:
Price (£) Demand Profit (£)
1150 415 121,750
1185 405 133,650
1210 390 141,600
1235 380 146,200
1260 345 140,100
1285 302 113,640
1310 270 75,600

1485 214 62,370
1510 210 61,500
1540 200 59,200
From the table, we can see that the maximum profit is obtained at a price of £1210, which gives a profit of £141,600. The optimal demand at this price is 390 units.
Interpretation: The company can maximize its profit by setting the price of the electric bicycle at £1210, and the optimal demand at this price is 390 units. The company can earn a profit of £141,600 if it sells 390 electric bicycles at this price.
If the supply cost of each electric bicycle is £250, then the profit function becomes:
Profit = (sale price - £250 - £740) * demand
Profit = (sale price - £990) * demand
Using the same method as before, we can calculate the profit for each price level:
Price (£) Demand Profit (£)
1150 415 157,450
1185 405 169,950
1210 390 177,300

1260 345 174,150
1285 302 146,890
1310 270 110,250
1335 255 96,525
1360 246 95,040

The maximum profit is obtained at a price of £1210, which gives a profit of £177,300. The optimal demand at this price is 390 units.
Interpretation: If the supply cost of each electric bicycle is reduced to £250, then the optimal price remains the same as before at £1210. However, the maximum profit increases to £177,300, which is an increase of £35,700 compared to the previous scenario.
If the supply cost of each electric bicycle is £950, and the company decides to set the price less than £1300, then we can repeat the above process to find the optimal price and profit.
