Find surface area
SA=2pir^2+2hpir
h=42
r=1.5
SA=2pi1.5^2+2(42)pi1.5
SA=4.5pi+126pi
SA=130.5pi square inches
area/areacoverdperspray≤numberofsprays
130.5pi/150
2.73
so buy 3 cans because you can't get 0.73 cans
A
This can be displayed as 5x = 28 - 2x
We can solve for the value of x by making the following changes:
<u>Add 2x to both sides</u>
7x = 28
<u>Divide by 7</u>
x = 4
Answer:
Insert non-suspicious whistling
Answer:
Axis of Symmetry:
x=2
Vertex:
(2,11)
Step-by-step explanation:
Finding the derivative:
f'(x)=-10x+20
Setting the slope equal to zero:
-10x+20=0 x-2=0 x=2
Finding vertex:
f(2)=-5*(2)^2+20*2-9
=-20+40-9=20-9=11
(2,11)
Answer:
yes
A function whose graph is a straight line is a linear function. The graph of a nonlinear function is not a straight line.
