Answer:
its D
Step-by-step explanation:
3r+2(12r+7)<5r-8
3r+24r+14<5r-8
27r+14<5r-8
22<-22r
when you devide by a negative the signs flips so
22/-22>-22/-22r
-1>r
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>
The graph<span> of </span>y<span> = </span>tan x has<span> vertical </span>asymptotes<span> at </span>x<span> = π/2 and </span>x<span> = –π/2,. The period of the </span>tangent function is<span> π, vertical </span>asymptotes<span> also occur when </span>x<span> = π/2 + nπ, where n </span>is<span> an integer.</span>
2x-1=x^2
If you plug these two equations into a graphing calculator, like desmos.com, you can see that the two lines will intersect at (1, 1).
