Answer:
1. 3.14
Step-by-step explanation:
If we have

That just equals

For example, consider function

The inverse of that function is




So

If we compose the function, f(x) into f^-1(x).
We get

That proof of that.
1. Here x=f^-1(3.14)and f(3.14) cancel out so the answer is 3.14
2. We first find f(-7) which is -12,
We then find f(-12)= 5 so the answer here is 5.

for every member to get a shirt you would need to order 9 packages of shirt (because 5 times 9 is 45) and for caps the minimum to order would be 15 packages of caps
explanation
caps=3 per package
shirts=5 per package
divide 45 by and get 15
15 is the total packages of hats needed to order
for shirt 45 divided by 5 is 9
9 is the total packages of shirts needed to order
A toy company needs to profit at least $500 from selling cars and trucks. A car can make a profit $2 while the truck can $3 profit.
let x be the number of cars
let y be the number of truck
If 200 resources for the car per week, we have:
Profit = $2x + $3y
$500 = $2*200 + $3*y
$500 - $400 = $3y
100 = 3y
y =100/3 = 33.33
The number of trucks needs to produce per week is at least 34 pieces.
