number of cards = 100
number less than 14 = {2,3,...,13} = 12
number perfect square = {4, 9, 16, 25, 36, 49, 64, 81, 100} = 9
so
a) probability = 12/100 = 3/25
b) probability = 9/100
Answer:
- (b - 9)(b + 8)
Step-by-step explanation:
72 + b - b² ← factor out - 1 from each term and rearrange into standard form
= - (b² - b - 72) ← factor the quadratic
Consider the factors of the constant term (- 72) which sum to give the coefficient of the b- term (- 1)
The factors are - 9 and + 8
Use these factors to split the b- term
b² - 9b + 8b - 72 ( factor the first/second and third/fourth terms )
b(b - 9) + 8(b - 9) ← factor out (b - 9) from each term
(b - 9)(b + 8)
Then
72 + b - b² = - (b - 9)(b + 8)
Original price $24.99
Now it's on sale with 30% off
So the price now will be 24.99 - 30% of 24.99
Or we can say that it will be 70% of the initial price
So:
24,99 . 70% = 24,99 . 70/100 = 17,493
The price will be $17,493
One way is to solve for the inverse of the first function
remember, to solve, replace f(x) or g(x) with y, switch x and y, solve for y and replace it with 
A.
nope, not A
<h3>What is the inverse function?</h3>
The inverse function of a function f is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by 
B.
![f^{-1}(x)=\sqrt[3]{((x-16)/3)}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Csqrt%5B3%5D%7B%28%28x-16%29%2F3%29%7D)
nope, not the same
not B
C.
The correct, answer is C.
