A right circular cylinder is changing shape. The radius is decreasing at the rate of 2 inches/sec while it's height is increasing at the rate of 5 inches/sec. When the radius is 4 inches and the height is 6 inches, how fast is the volume changing? Round your answer to three decimal places
Answers
The volume of the right circular cylinder is changing at a rate of approximately 50.265 cubic inches per second.
Given that a right circular cylinder is changing shape.
The radius is decreasing at the rate of 2 inches/sec
dr/dt = -2 inches
The radius is increasing at the rate of 2 inches/sec
dh/dt=5 inches
We have to find dv/dt when r is 4 inches and h is 6 inches.
Volume=πr²h
Differentiate with respect to 't' to find the change of volume:
[tex]\frac{dV}{dt}=\pi(2rh\frac{dr}{dt}+r^2\frac{dh}{dt})[/tex]
Plug in the values:
[tex]\frac{dV}{dt}=3.14(2(4)(-2)(6) + 16(5))[/tex]
[tex]=3.14(-96+80)[/tex]
[tex]=3.14(-16)[/tex]
[tex]=-50.265[/tex] inch³/sec.
Hence, the volume change is -50.265 inch³/sec.

Forces affect motions in living and nonliving things. In a human, swallowed food moves down the esophagus into the stomach, even if the human is upside down doing a handstand. Which force moves food through the esophagus into the stomach?
a:Frictional force in the esophagus moves food through the esophagus.
b:Gravitational force pulls food through the esophagus.
c:Magnetic force in the stomach pulls food through the esophagus into the stomach.
d:Push force from contractions of the esophagus moves food through the esophagus.
Answers
Answer:
a
Step-by-step explanation:
The force that moves food through the esophagus into the stomach is;
d:Push force from contractions of the esophagus moves food through the esophagus.
When we are sitting upright and eat food, the food moves down the esophagus and into the stomach.
Now, that will be a logical explanation because just like a flow, it goes with gravity position and would go from up down like a free fall.
However, when we are not sitting upright but upside down with our head on the ground and legs up, what happens is that the food still goes to the stomach via the oesophagus but this time because of the position of the body, the oesophagus will contract i.e. contraction in the walls of the food pipe which will lead to a push force that takes the food into the stomach.

At a store, a hat has a regular price of x dollars. During a sale, the price of the hat is discounted by 20%. The expression 0.8x describes the discounted price, in dollars, of the hat. Which expression also describes the discounted price, in dollars, of the hat?
Answers
Answer: D) x - 0.2x
Step-by-step explanation:
The hat has a regular price of x dollars.
This price is reduced by 20% so the relevant expression for the discount is; 20% * x or; 0.2x
The discounted price will be the price of the hat less the discount which means the formula will be;
= Price - discount
= x - 0.2x

You are an office manager. You have been asked to research the cost of an online messaging service. The service charges $3.25 per employee each month. However, if you sign up for a full one-year subscription, the charge drops to $2.80 per employee per month. Your office has 20 employees.
Answers
Answer:
The final cost for the service that offers the better deal is $56 per month, in total for the whole year it's $672.
The cost for the one that offers the worse deal is $65 per month.
Step-by-step explanation:
All we need to do is multiply the amount of money by the number of employees.
So:
20 × $2.80 = $56
(Calculations for worse deal)
20 × $3.25 = $65
Answer: $108.00
Step-by-step explanation:
$3.25 per employee, per month (3.25 x 20 x 12) = $780/ mo
$2.80 per employee, per month (2.80 x 20 x 12) = $672/mo
subtract the two, which equals $108.00 will be saved each year with the one-year subscription.

A map has the scale 0.75 of an inch equals 220 miles. The distance from Springfield to Glenview is 6 inches. How many actual miles separate Springfield from Glenview?
Answers
Answer:
1,760 actual miles separate Springfield from Glenview.
Step-by-step explanation:
Scaling
Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing real dimensions by a constant factor. We use scaling when representing geographic locations on a map.
The map has the scale:
0.75 inch => 220 miles
This gives us the scaling factor as 220/0.75. There is no need to divide.
We are given the distance from Springfield to Glenview is 6 inches on the map. The actual distance is
6*220/0.75 = 1,760
1,760 actual miles separate Springfield from Glenview.
