vagabundo [1.1K]

Answer:

44 pi centimeters cubed

Step-by-step explanation:

Since, base radius and height of cone are equal to to that of cylinder. Hence,

$Volume \: of \: cone \\ = \frac{1}{3} \times Volume \: of \: cylinder \\ = \frac{1}{3} \times132\pi \\ = 44\pi \: {cm}^{3}$

I think u do the ones in the parenthesis first bc of PEMDAS since it's both negative it become positive and u can cross out both the 2's and that leaves u with 1/7 and then u just times 1/7 with 8 and then u get 8/7

Solve (9^62773 + 2)^83721

shutvik [7]

Remember the order of operations and do what is in parenthses first.

Take 9 to its power first, then add 2. Once you get that, take that answer to the 83721 power.

I would give you the answer, but my calculator is saying invalid input every time I am trying to use such high exponents. Sorry :( But I hope that this helps

Answer:

A. -2

B. -10

Step-by-step explanation:

The slope of a perpendicular line will be the negative reciprocal of the slope of the given line:

-1/(1/2) = -2 . . . . slope of the perpendicular line

The y-intercept will let the given point satisfy the equation ...

y = -2x +b

2 = -2(-6) +b

-10 = b . . . . . . . subtract 12. This is the y-intercept.
