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.

what's the slope between (5,-2) and (-7,22)

Answers

Answer: The answer is: -2

Step-by-step explanation:

Here, suppose

(5,-2)=(x1, y1)

(-7,22)=(x2, y2)

Now, use the slope equation to find slope(m).

y2-y1=m(x2-x1)

or,m=y2-y1/x2-x1

After this, just substitute the values from above.

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

Writing in an Interval Form, note that we use the least value in the left and the most value in the right.

From [a,b], [a,b), (a,b] or (a,b) | a must be less than b.

Hence , the Vladas hypothesis which is incorrect is x² + y² = 25 which is option (c) .

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.
