Explanation:
We view the ramp as a right triangle. The hypotenuse is 4.2 and the vertical side .7, which is opposite the angle
θ
we seek.

I'm going to finish the problem but I'll note if we were actually building the ramp we don't need to know the angle; this sine is sufficient.

which I think is a pretty steep ramp for a wheelchair.
There will be another inverse sine that is the supplementary angle, around

, but we can rule that out as a value for a ramp wedge angle.
Answer:
y = -1/4x +3
Step-by-step explanation:
Hope this helps!
The “1/2” caused the parabola to be vertically compressed meaning it got wider.
and the “-2” caused the parabola to move 2 units to the right
Therefore the correct answer should be C.
Answer:
66
-30
___
36
Step-by-step explanation:
The answer is 36 do 66 minus 36.
Answer:
11 units
Step-by-step explanation:
simply subtract -3 from 8, which is the same as adding 3 and 8, so the answer is 11 units.
