Answer:
1- 51.496yd 2- 39.25ft 3- 163.28cm 4- 53.38mm 5- 50.24in 6-94.2ft 7-18.84yd 8- 207.24m
Step-by-step explanation:
So how you do circumference is you find the diameter and times it by pi.
for 1. you will do 8.2 times 2 for the diameter then times it by pi and get 51.496 yards.
for 2 you would do 12.5 times pi and get 39.25ft
for 3 you would do 26 times 2 which is 52 then multiply it by pi which is 163.28cm
for 4 you do 17 times pi which is 53.38mm
for 5 you do 16 times pi which is 50.24in
for 6 you do 30 times pi which is 94.2ft
for 7 you do 3 times 2 which is 6 then multiply by pi which is 18.84yd
for 8 you do 33 times 2 which is 66 then multiply by pi which is 207.24m.

Prove BUGS is a trapezoid
Given the coordinates, to prove a trapezoid; all we need to do is to check if one pair of sides is parallel.
<u></u>
<u>Taking BU and GS as a pair</u>
First, we calculate the slope using:

For BU
--- 
--- 
So, we have:



For GS
--- 
--- 
So, we have:



<em>The slope of BU and GS are not the same; hence, they are not parallel.</em>
<u>Taking BS and GU as a pair</u>
Calculate the slope
For BS
--- 
--- 
So, we have:



For GU
--- 
--- 
So, we have:



The slope of BS and GU are the same; hence, they are parallel.
<em>BUGS is a trapezoid because BS and GU have the same slope</em>
Answer:
144 feets
Step-by-step explanation:
Look on s(t) like quadratic function. We need to find maximum of the function using 1st diferetioal:
s(t)=-16t^2+64t+80
s’(t)=-32t+64
S’(t)=0 if t=2
For t>2, s’(t)<0
For t<2, s’(t)>0. So the maximum od function is in the point 2.
S(2)=-16*4+64*2+80=-64+128+80=144
