Mine is pretty rough but hope it helps look at the attached image.
Answer:
B
Step-by-step explanation:
x=-2, f(-2)=-7
x=0, f(0)=5
x=1, f(1)=2
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>
First distribute
combine like terms
subtract 6x from both sides
then you get no solutions which is a special case
Answer:

Step-by-step explanation:
Given:
Consecutive Terms: k-5, k+7, k+55
Required:
Determine the value of k
To do this, we make use of the concept of common ratio.
The common ratio (r) of a geometric sequence is:

In other words:

Where 1, 2 and 3 represents the terms of the progression/sequence
So:
becomes
