Answer:
a² + b² = c²
28² + 45² = c²
784 + 2025 = 2809
Square root of 2809 is 53
The hypotenuse is 53
45/117
Both numbers can be divide by 9
5/13
Probability = 1/4, or 25%
The probability of rolling an even number on a die: 1/2
(1, 2, 3, 4, 5, 6; 3 are even numbers, 3/6 = 1/2)
The probability of flipping heads: 1/2
(heads or tails)
1/2 x 1/2 = 1/4
Ok to figure out if one is an inverse function, you plug in y for x and substitute f(x) with x and solve for y.
We only have to do this for 1 of the functions so we will take f(x)
x = 5y +1/y
I’m not sure you can solve for y here therefore g(x) is not an inverse function of f(x)
