Answer:
(x+3)^2 + (y-2) ^2 = 25
Step-by-step explanation:
Equation of a circle: (x-h)^2 + (y-k)^2 = r^2
Center at (h,k)
Radius=r
Answer:
add the whole numbers. -9+10=1
1 2-3/7
remove one digit from the whole number:. 1-1=0
add the denominator to 2=7+2=9
:. 9-3/7=6/7
answer=6/7
Answer:
53 boxes
Step-by-step explanation:
Subtract the end amount from the beginning amount to find the number of boxes already delivered.
89-36=53
Answer:
-9

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>
