Evan runs a website that has gotten quite popular. However, its popularity seems to be decreasing and the site is now getting 7%
anyanavicka [17]

Answer:

(a-b) *(a-b) *(a-b)

=(a*a*a) -3*(a*a*b)+3*(a*b*b)-(b*b*b)

34000*(1-7%)*(1-7%)*(1-7%)

=34000*(1-0.07)*(1-0.07)*(1-0.07)

=34000*[(1*1*1)-3*(1*1*0.07)+3*(1*0.07*0.07)-(0.07*0.07*0.07)]

=34000*(1-0.21+0.0147-0.000343)

=34000*(0.804357)

=34*1000*(804.357/1000)

=34*804.357

=<u>27348.138</u>

<u>=</u><u>27348</u>

Find the circumference and area of a circle<br>with a radius of 5 feet.​
iVinArrow [24]

Circumference = 2(pi)r

Area = (pi)r^2

r = 5

5 * 2 = 10

Circumference = 10π

5 * 5 = 25

Area = 25π

Using 3.14 as pi substitute:

5 * 3.14 = 15.7

15.7 * 2 = 31.4

Circumference = 31.4

5 * 5 = 25

25 * 3.14 = 78.5

Area = 78.5
