Answer:
The first pyramid:
63x
39x 24x
23x 16x 8x
The second pyramid:
162x
82x 80x
4x 78x 2x
The third pyramid:
12a+2b
9a+b 3a+b
9a b 3a
The fourth pyramid:
-19a
-5a -14a
3a -8a -6a
Step-by-step explanation:
All that an alegbra pyramid is is adding the two terms below it.
So you can see how I added the terms that lied below each number, such as in number 1: I added 23x and 16x to get me 39x, and I added 16x and 8x to get me 24.
Hope this helped!
Answer:
72
Step-by-step explanation:
When I see the words "instantaneous rate of change", I have to assume that you're in some stage of pre-calculus in your math class.
The instantaneous rate of change of a function is just its first derivative.
We have the function
V(r) = 3 π r²
and we need its first derivative with respect to ' r '. That shouldn't be
too hard, because the ' 3 π ' is nothing but constants.
Watch me while I do it slowly for you:
-- The derivative of ' r² ' with respect to ' r ' is ' 2r '.
-- The derivative of V(r) with respect to ' r ' is (3 π) times the derivative of ' r² '.
-- The derivative of V(r) with respect to ' r ' is (3 π) times (2r) = <u>6 π r</u> .
The value of the derivative when r=3 is (6 π 3) = 18π = about <em>56.5 feet³/foot .</em>
