The required functions are obtained as f(x) = x/5, f(x) = ∛(2x), f(x) = x - 10 and f(x) = 2x/3 - 17 respectively.
What is the inverse of a function?The inverse of a function y = f(x) is defined as a function having range as the domain of the function f(x) and domain as the range. Mathematically it can be written as f⁻¹(y) = x which implies that f⁻¹(f(x)) = x.
The given problem can be solved as follows,
(a) f⁻¹(x) = 5x
Substitute x = f(x) to obtain,
f⁻¹(f(x)) = 5f(x)
=> x = 5f(x)
=> f(x) = x/5
(b) f⁻¹(x) = x³/2
Substitute x = f(x) to obtain,
f⁻¹(f(x)) = f(x)³/2
=> x = f(x)³/2
=> f(x) = ∛(2x)
(c) f⁻¹(x) = x + 10
Substitute x = f(x) to obtain,
f⁻¹(f(x)) = f(x) + 10
=> x = f(x) + 10
=> f(x) = x - 10
(d) f⁻¹(x) = 3( x + 17)/2
Substitute x = f(x) to obtain,
f⁻¹(f(x)) = 3( f(x) + 17)/2
=> 2x = 3( f(x) + 17)
=> 2x/3 = f(x) + 17
=> f(x) = 2x/3 - 17
Hence, the functions for the given inverse functions are f(x) = x/5, f(x) = ∛(2x), f(x) = x - 10 and f(x) = 2x/3 - 17 respectively.

Answer:
1) Yes, table shows a probability distribution
2) Mean = 1.5
3) Standard Deviation = 1.1
Step-by-step explanation:
PART 1:
For the table to show a probability distribution, the sum of all probabilities should be equal to 1
Sum of probabilities = 0.358 + 0.443 + 0.174 + 0.025
Sum of probabilities = 1
Hence, the table shows the probability distribution.
PART 2:
The formula for mean is given by:
Mean = Sum of terms/ Total no. of terms
Mean = (0+1+2+3) / 4
Mean = 1.5
PART 3:
The formula for standard deviation is given by:

Renee can see a 25 square foot quilt in 16 hours. Genera can sew the same size quilt in 12 hours. How long would it take them to see the quilt together?
Answers
28 hours because they are too long from each other
Answer:
Approximately 6.86 hours.
Step-by-step explanation:
Renee sews at a rate of 1.5625 sq ft an hour. Found using square feet divided by hours.
Genera sews at a rate of 2.084 sq ft an hour. Found using square feet divided by hours.
To find how fast they can sew the quilt together, we must add their sewing speeds together: 1.5626 + 2.084 = 3.64583333.
Using this equation we can divide a 25 sq ft quilt by their speed of 3.64583333 to get approximately 6.86 hours.
The answer is approximate because we used rounded decimals.

At 50, Brian sets up an IRA, where he plans to deposit $12,000 at the end of each year until age 75. Find the amount of the annuity if he invests in a stock fund that yields 4% compounded annually.
Answers
Answer: the amount of the annuity is $501000
Step-by-step explanation:
We would apply the future value which is expressed as
FV = C × [{(1 + r)^n - 1}/r]
Where
C represents the yearly payments.
FV represents the amount of money
in your account at the end of 25 years.
r represents the annual rate.
n represents number of years or period.
From the information given,
r = 4% = 4/100 = 0.04
C = $12000
n = 75 - 50 = 25
Therefore,
FV = 12000 × [{(1 + 0.04)^25 - 1}/0.04]
FV = 12000 × [{2.67 - 1}/0.04]
FV = 12000 × 41.75
FV = $501000

Nelson decides to invest $1,000,000 in a period annuity that earns 4.8% APR
compounded monthly for a period of 15 years. How many years will it take
Nelson to earn back his initial investment?
Answers
Answer:
21yearsStep-by-step explanation:
Amount invested by Nelson = $1,000,000
Interest rate per month = 4.8%
Simple Interest = Principal * Rate * Time/100
simple Interest = $1,000,000 * 4.8 *(1/12)/100
simple Interest = $1,000,000 * 4.8/1200
simple interest = $4,000/ month
Simple interest for one year = $4,000*12 = $48,000
In order to determine the number of years it will take Nelson to earn back his initial investment, we will divide its initial investment by the interest earned on the investment yearly as shown;
amount of years = $1,000,000/ $48,000
Amount of years = 20.8years ≈ 21years
10.7 years

Which equation correctly represents the distance between - 15.1 and -3.9 on a number line?
- 3.9 - (-15.1)] = 11.2
-3.9 - 15.1 = -11.2
|- 15.2 + (-3.9) |= 19
-15.1 - 3.9 = -19
Answers
Answer:
Step-by-step explanation:
Keep in mind that distance is positive, not negative. Eliminate the negative results.
- 3.9 - (-15.1)] = 11.2 is correct. -(-15.1) - 3.9 is approximately 15 - 4, or 11, which agrees with the 11.2 correct result.
