Question

The function f(x) = 0.4x² – 36x +1000, models the number of accidents, f(x), per 50 million

Answer 1

Answer:

$f(50) = 200$

There are 200 accidents per 50 million miles for 50 year old drivers

Step-by-step explanation:

Given

$f(x) = 0.4x^2 - 36x + 1000$

Required

Determine f(50)

To do this, substitute 50 for x

$f(x) = 0.4x^2 - 36x + 1000$

$f(50) = 0.4 * 50^2 - 36 * 50 + 1000$

$f(50) = 0.4 * 2500 - 1800 + 1000$

$f(50) = 1000 - 1800 + 1000$

$f(50) = 200$

Interpretation: There are 200 accidents per 50 million miles for 50 year old drivers
