Answer:
$10 + $2m
m = 1 mile that Jana bikes.
Step-by-step explanation:
4.25 + 1.25m + 5.75 + 0.75m
Add like terms
10 + 2m
23 because if there is 14 people remaining and 9 went home early so it would equal 23 because 14+9=23 so there was 23 people
at the party
The answer is 80 because 400 divided by 5 is 80
Given:
r = radius = 4
h = height = 12
dr = error in radius = 0.2
What we want to find
dV = error in volume
Use the derivative to find the differential dV
V = pi*r^2*h
dV/dr = d/dr[ pi*r^2*h ]
dV/dr = 2pi*r*h
dV = 2pi*r*h*dr
dV = 2pi*4*12*0.2
dV = 19.2pi
So if the error in measuring the radius is +-0.2 inches, then the error in the cylinder volume is +-19.2pi cubic inches (we either measure the volume to be 19.2pi cubic inches too big, or 19.2pi cubic inches too small)
----------------------------------------------------------------------------------
Final Answer: Plus or minus 19.2pi cubic inches
Note: your teacher may want you to drop the "plus or minus" part
