Let,
f(x) = -2x+34
g(x) = (-x/3) - 10
h(x) = -|3x|
k(x) = (x-2)^2

This is a trial and error type of problem (aka "guess and check"). There are 24 combinations to try out for each problem, so it might take a while. It turns out that 

g(h(k(f(15)))) = -6
f(k(g(h(8)))) = 2

So the order for part A should be: f, k, h, g
The order for part B should be: h, g, k f
note how I'm working from the right and moving left (working inside and moving out).


Here's proof of both claims

-----------------------------------------

Proof of Claim 1:

f(x) = -2x+34
f(15) = -2(15)+34
f(15) = 4
-----------------
k(x) = (x-2)^2
k(f(15)) = (f(15)-2)^2
k(f(15)) = (4-2)^2
k(f(15)) = 4
-----------------
h(x) = -|3x|
h(k(f(15))) = -|3*k(f(15))|
h(k(f(15))) = -|3*4|
h(k(f(15))) = -12
-----------------
g(x) = (-x/3) - 10
g(h(k(f(15))) ) = (-h(k(f(15))) /3) - 10
g(h(k(f(15))) ) = (-(-12) /3) - 10
g(h(k(f(15))) ) = -6

-----------------------------------------

Proof of Claim 2:

h(x) = -|3x|
h(8) = -|3*8|
h(8) = -24
---------------
g(x) = (-x/3) - 10
g(h(8)) = (-h(8)/3) - 10
g(h(8)) = (-(-24)/3) - 10
g(h(8)) = -2
---------------
k(x) = (x-2)^2
k(g(h(8))) = (g(h(8))-2)^2
k(g(h(8))) = (-2-2)^2
k(g(h(8))) = 16
---------------
f(x) = -2x+34
f(k(g(h(8))) ) = -2*(k(g(h(8))) )+34
f(k(g(h(8))) ) = -2*(16)+34
f(k(g(h(8))) ) = 2

A small business has 15 full-time employees. How many people does the small business employ if the full-time workers make up 30%
Alexxx [7]

Answer:

50 employees

Step-by-step explanation:

The total number of employees the business has will have to be made up the full-time employees and part-time employees.

The number of full-time employees = 15

Let the total number of  employees = x

15 = 30 percent of x

15 = 30/100 \times x\\x=1500/30 = 50

The company has a total of 50 employees

An insured has $5,000 of medical coverage on a personal auto policy at the time of a covered accident. The insured and two passe
Vlad1618 [11]

Answer: 14,000 $ Max will be paid and 5000$ per person.

Step-by-step explanation:

In this case, we can assume the following:

1. That the policy covers only the insured one and not the passengers

2. The policy cover all the injured.

Now, the policy covers 5000$ of medical treatment, so, the medical treatment for the insured is 7000$.

To this quantity you'll have to take out the policy coverage which is 5000$, so: 7000 - 5000 = 2000$.

Finally, we just have to to the sum, of all quantity, because the passengers are not included in the policy, therefore:

8000 + 4000 + 2000 = 14000 $.

That is the maximum paid of all, and 5000$ will pay the policy for the injured only.

Now, if we assume that the passengers are also covered by the policy, then:

7000 - 5000 = 2000

8000 - 5000 = 3000

4000 - 5000 = -1000 it won t pay anything.

So if we sum 5000 + 5000 + 4000 = 14000$.

We got the same result assuming the policy with all.

Therefore the final answer is that the policy will pay 14000$ for all.

HELPP describe the mistake made in the work shown
solmaris [256]

Step-by-step explanation:

-2(8m+8) = -16

-16m-16 = -16

-16m = -16+16

-16m= 0

m= 16

Therefore, the value of m is 16.

Sorry but is that below another question? or is it whole a same question?

-16m÷16 = -32÷16

-m = -2

remove those "-" signs from both sides. So, the answer is 2.
