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.
A and B are the answers.
If you need proof, just ask in the comments, and I’ll get back to you.
I hope this helps!
The equation of the line:
y = m x + c
m is the slope , c is constant
so m = 1/2 (given)
so y = (1/2) x + c
c will be calculated from the given point as y -1 when x =-3
then -1 = (1/2) * -3 + c
c = -1 +(1/2)*3 = 1/2
so y = (1/2) x + (1/2)
the graph of function is as shown in the figure
Answer: 4/5 * 7^1/2 ==> 1st option
Step-by-step explanation:
3(7/25)^1/2-(28/25)^1/2+(63/25)^1/2=
3(7)^1/2 / 5 -(4*7)^1/2 / 5 +(9*7)^1/2 / 5=
3(7)^1/2 / 5 -2(7)^1/2 / 5 +3(7)^1/2 / 5=
(3-2+3)(7^1/2 / 5)=
4(7^1/2 / 5)=4/5 * 7^1/2 ==> 1st option
Answer:
18
Step-by-step explanation:
$72 divided by 4 is 18, 18 x 4 is 72.
