Answer:
Option C is the correct answer.
Step-by-step explanation:
We are given,
<em>A graph where the function first increases and then decreases to touch the x-axis and the increases.</em>
It is required to find the corresponding situations.
So, from the options we have that,
The graph represents the speed of a vehicle which first increases (as it accelerates), then decreases (slows down) and then touch the x-axis (stops at the light) and then increases (accelerates on the ramp for a freeway).
Hence, option C is scenario that the graph describes.
Answer:
b ≈ 48.6°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin b =
=
, then
b =
(
) ≈ 48.6° ( to 1 dec. place )
The other side is x^2+9
x^3-27/x-3= x^2+9
Option A is your answer.
Subtract 3 from both sides to get zero on the right side of the equal sign.
8 - 3 = 5.
So that becomes your constant term in the equation.
