Answer:
Step-by-step explanation:
I'm going to use a Pythagorean identity to help make this make sense.

We are given that cos(0) = 1, so
cos²θ = 1² which simplifies to
cos²θ = 1. So filling into our trig identity:
sin²θ + 1 = 1 and
sin²θ = 0 then
sinθ = √0 so
sinθ = 0
so
sin(0) = 0
Answer: x < -3.5
Step-by-step explanation:
Subtract 3 from both sides and we get
-4x > 14
We divide -4 on both sides, but be careful because we have to flip the sign since it's a negative number.
x < -3.5
Answer:
(-1,-1)
Step-by-step explanation:
down 2 affects the y, so 1-2=-1
Left 4 affects the x, so 3-4=-1
Answer:
Negative and Nonlinear
Step-by-step explanation:
From left to right, the dots seem to be going downward. The scatterplot has a negative association.
The dots form a curved line. A curved line on a graph is nonlinear.
The scatterplot has a negative and nonlinear association.
