Answer:
A. (f-g)(x) = -5^x +3x -2
Step-by-step explanation:
The only terms that can be combined are the constants.
(f -g)(x) = f(x) -g(x)
(f -g)(x) = (-5^x -4) -(-3x -2) = -5^x -4 +3x +2
(f -g)(x) = -5x^4 +3x -2 . . . . . matches A

You will receive a free beverage and free desert on your 60th visit.
Beverage- 1, 2, 3, 4, 5, 6
Visits- 12, 24, 36 ,48 ,60
Desert- 1, 2, 3 ,4
Visits- 15, 30, 45, 60
Notice how for beverages at 60 visits you get your 6th drink for free, and for deserts, at you 60 visits you receive your 4 free desert.
So, since both numbers have the same number (60) of visits which is their common multiple between the 2, you answer is 60.
Answer:
It will take 0.72s for the football to hits the ground.
Step-by-step explanation:
We have that the equaation for the height of the football is
The football will hit the ground when .
Multiplying by -1
To solve this equation, we need the bhaskara formula:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots such that , given by the following formulas:
In this problem, we have that:
So
It cannot take negative seconds for the ball to hit the ground.
So it will take 0.72s for the football to hits the ground.
