Easy, that is the slope from (2,f(2)) to (3,f(3))
remember that the slope between the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
find f(2) and f(3)
f(2)=2²+6(2)+5=4+12+5=21
f(3)=3²+6(3)+5=9+18+5=32
so the slope from (2,21) to (3,32) is (32-21)/(3-2)=11/1=11
answer is 11
9,660/0.5m3=19.320kg/m^3
Get it from this equation m=pV
p is density ,V volume, m mass
Hope it helps ;)
Answer:
110.25π 
Step-by-step explanation:
The can is a circular cylinder and has the formula for the volume to be
V = 
r = 3.5 and h = 11
Since the paint is now 2 in. from the top of the can, then there are 9 in. left in the can, which means there is 9/11 of the total volume in the can.
Therefore, 
we get V = (9/11)(12.25)(11)π
= 110.25π
The track is a square with half circle on its right and left side. The area of the square is 128 feet². The length is 22.6 feet
<h3>How to illustrate the information?</h3>
It should be noted that the area of the square will be:
= x².
Therefore, 128 = x².
x ,= ✓128
x = 11.3
Therefore the radius of the circle will be:
= 11.3/2
= 5.65
The length of the truck will be:
= 11.3 + 5.65 + 5.65
= 22.6
The length is 22.6 feet

The track has ____ sides of the square and the distance around
Answer:
y =-3
Step-by-step explanation:
4(y+1)=-8
Divide each side by 4
4/4(y+1)=-8/4
y+1 = -2
Subtract 1 from each side
y+1-1 = -2-1
y = -3
