1/2•(2p-6)(p+1)
1/2•(2p^2+2p-6p-6)
1/2•(2p^2-4p-6)
p^2-2p-3
D = 4n - 2
+2 +2
d + 2 = 4n
Divide both sides by 4
n = d + 2 / 4
You have to divided 11 by 2 in order to get the radius
And you’ll get 5.5
r=5.5
h=12
Your formula is (1/3)(pi)(r^2)(h)
Answer:
y=1/2x+5
Step-by-step explanation:
- standard form: y-0=1/2(x- -10) *(x- -10) = (x+10)
- y=1/2x+5 which is now in slope-intercept
