I need help with this

1 answer:

3 0

Volume formula: 1/3pir^2h

From this, 1/3(pi)(8^2)(15)= 1005.3

This is not a answer choice but… 1004.8 is the best choice they might have used 3.14 instead of the full pi

Hope this helps

Answer:

slope = 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, 1)

m = $\frac{1-0}{0+1}$ = 1

One positive number is the square of another positive number. their sum is 132. find the numbers.

Jet001 [13]

X +x²= 132
x +x²-132= 132-132
x²+x -132 = 0
(x-11) (x+12) = 0
x-11 = 0 X+12=0
x-11+11 = 0+11 X+12-12=0-12
x =11 x= -12

Check
x +x²= 132 x +x²= 132
-12 +-12²= 132 11 +11²= 132
-12 + 144 = 132 11+ 121=132
132= 132 132=132

Since the problem says positive the answer is (11,121)
