Answer:
<em>f(50) = 109.44943 feet</em>
Step-by-step explanation:
<u>Modeling</u>
The model of a situation where the skid distance f is measured against the car speed x can be expressed as:
Using this equation, we can predict the skid distance for a car that is driving at x=50 mph by substituting in the equation of the model:
f(50) = 109.44943 feet
<span>f(x) = 4x + 3
g(x) = -2x + 5
(f o g) (5) means the function of g when g is a function of 5
(the function of the function concept)
so we need to get g(5) firstly
</span>
<span>g(x) = -2x + 5
g(5)= -2(5) + 5 = -5
After that, f(g(5)) = f(-5) = 4(-5) + 3 = -20 + 3 = -17
I hope that helps

B, because 12 inches equals one foot so it's one foot a minute. In an hour it would walk 60 feet as to A would only walk 52
Answer:
A: The scale would be x3
B: 4/3
Step-by-step explanation:
Y is just x multiplied by -3
