Answer:
y ≈ 5.2
Step-by-step explanation:
∠ F = 180° - (42 + 48)° ← sum of angles in a triangle
∠ F = 180° - 90° = 90°
Thus Δ DEF is right at F
Using the sine ratio in the right triangle
sin48° = 
= 
= 
( multiply both sides by 7 )
7 × sin48° = y , then
y ≈ 5.2 ( to the nearest tenth )
Answer:
a. y = -x² + 2x - 8
b. y = 
c. y = x³+ 3
Step-by-step explanation:
Answer:
-2 x -3/2
Step-by-step explanation:
-2 x -3/2
That would equal three, which is more than 2.

The correct answer is 4ft
<span>because the radius of that circle </span>
<span>(x+10<span>)^2</span>+(y−8<span>)^2</span>=<span>4^2</span></span>
<span>is 4</span>
It sucks that points have to be used in order to post questions.
Openstudy - the company that merged into Brainly - was much better.
Anyway, I think that the answer to this question is A. I'm not sure, though.
