Answer:
The fencing will cost $330.09
Step-by-step explanation:
First we have to calculate the perimeter of the semicircle for that we use the following formula:
d = diameter = 29ft
s = semicircle
π = 3.14
s = d * 1/2 * π
we replace the values that we know
s = 29ft * 1/2 * 3.14
s = 45.53ft
Now we multiply the number of feet by the price of what comes out 1 foot of fence
45.53 * $7.25 = 330.0925
Round to the nearest hundredth
$330.0925 = $330.09
(x-h)^2+(y-k)^2=r^2
(x-0)^2+(y+2)^2=9^2
x^2+y^2+4+4y=81
x^2+y^2+4y-81+4=0
x^2+y^2+4y-77=0
Answer:
1, -1, -3
Step-by-step explanation:
6(x+x+2+x+4)=-18
6(3x+6)=-18
18x+36=-18
18x=-54
x=-3
so x=-3, x+2=-1, and x+4=1
Answer:
calculate the rise over the run.
therefore, it's -8/7
