Answer:
E. 400
Step-by-step explanation:
So this is how we set this up, and how we solve

Hope this helps!
So you are solving for circumference of a quarter circle: 
r= 28

The area of the space under the slide is 2.10 square meters
<h3>The vertical distance</h3>
The diagram in the question is added as an attachment
The vertical distance is represented by h.
So, we have:
sin(70) = h/2
Solve for h
h = 2 * sin(70)
Evaluate
h = 1.88 m
Hence, the vertical distance is 1.88 m
<h3>The length of the slide</h3>
This is calculated using
sin(40) = h/Slide
This gives
sin(40) = 1.88/Slide
Solve for Slide
Slide = 1.88/sin(40)
Evaluate
Slide = 2.92
Hence, the length of the slide is 2.92 m
<h3>The
area of the
space under the slide</h3>
This is calculated using:
A = 0.5 * h * slide * sin(∅)
Where
∅ = 90 - 40 = 50
So, we have:
A = 0.5 * 1.88 * 2.92 * sin(50)
Evaluate
A = 2.10
Hence, the area of the space under the slide is 2.10 square meters

It is B. The radius is 4. So the area is 16 pi. If you multiply that out it is about 50.
Answer:
they show parralel line and perpendicular line
if the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.
the x and y intercept are different
two solutions
Answer:
b) y= 3x - 5
Step-by-step explanation:
9x-15 ÷3 = 3x - 5
3y ÷ 3 = y
