Answer:
f(-2) = 0
f(0) = -4
f(4) = 12
Step-by-step explanation:
Given the function f(x) = x^2 - 4, we must plug in the values substituting x for each of the answers.
f(-2) = (-2)^2 - 4
-2 times itself is a positive 4, therefore:
f(-2) = 4 - 4
f(-2) = 0
We do the same for each answer.
f(0) = (0)^2 - 4
f(0) = -4
f(4) = (4)^2 - 4
f(4) = 16 - 4
f(4) = 12
It is incorrect because the length of the unknown side is the square root of 7,225.
If you use the pythagorean theorem and plug in the values,
a^2 + 132^2 = 157^2
a^2 + 17424 = 24649
-17424 -17424
_________________
a^2 = 7225
If you square root it, the final answer would be 85.
If you want I will help you by the answer just tell me if you want I will help you that's okey with me I am typing really fast
I'm not quite sure though, im thinking 65 represents the speed of the moving car.
