Answer:
Relative Size, S, is 1584.89
Step-by-step explanation:
The equation is 
Where,
- R is the measurement in Richter Scale
- S is the relative size of the earthquare
<u>It is given that in Richter Scale, an earthquake measured 3.2, so
.</u>
<em>They want to know relative size, S, so we put given information in equation and solve for S:</em>

<em>Converting to exponential form, we have:</em>

<em>Rounding to nearest hundredth, we have:</em>

Answer:
20 ft
Step-by-step explanation:
We know that
Perimeter of rectangle = 2(l + w)
Let the width be w
=> 104 = 2(32 + w)
=> 104/2 = 32 + w
=> 52 = 32 + w
=> 52 - 32 = w
=> 20 = w
Hence z
Width of playground is 20 ft
Answer: 650 Ft above the trough of the valley. Explanation 450 - (-200) = 650
I believe the answer is graph A.
