V (cube)=9³=729 cm³
V (cone)=1/3*π*R²*H= 1/3*π*3²*9=84.8 cm³
V (metal)= 729-84.8=644.2 cm³
Answer:
Part 1:
$4.50 a months
12 months in a year
$4.50 * 12 months = $54 dollars a year
Part 2:
Mr.Simon would record this transcation as a " - " because the maintenances fees deducts from this saving account.
Answer:
B)-1/4
Step-by-step explanation:
f(x) = 4x ; slope is 4
perpendicular , slope is opposite and reciprocals so slope of this perpendicular line is -1/4
Answer
B)-1/4
Answer:
Step-by-step explanation:
rate of leaking water = 9500 cm³/min
height of tank, H = 6 m = 600 cm
diameter of tank, = 4 m
radius of tank, R = 2 m = 200 cm
dh/dt = 20 cm/min
at any time, h = 2 m Let at that time radius of the tank is r.
According to the diagram
R / H = r / h
200 / 600 = r / h
r = h/3
The volume of tank is given by
Differentiate with respect to t
dV/dt = 279111.11 cm³/min
This is the volume of water increasing per minute in the tank.
Let C be the rate of volume of water pumped into the tank.
So, C = 279111.11 + 9500
C = 288611.11 cm³/min
Answer: C
Step-by-step explanation:
It is C because you are adding money to something you already have, hence positive integer
