Answer:

The volume of cone changing at rate [tex]\frac{400}{3}\pi in^3/s[/tex]

Step-by-step explanation:

Let r be the radius of cone and h be the height of cone

[tex]\frac{dr}{dt}=2 in/s[/tex]

[tex]\frac{dh}{dt}=-4 in/s[/tex]

We have to find the rate at which the volume of cone changing when r=10 in and h=20 in

Volume of cone

[tex]V=\frac{1}{3}\pi r^2 h[/tex]

Differentiate w.r.t t

[tex]\frac{dV}{dt}=\frac{1}{3}\pi (2rh\frac{dr}{dt}+r^2\frac{dh}{dt})[/tex]

Substitute the values

[tex]\frac{dV}{dt}=\frac{1}{3}\pi(2\times 10\times 20\times 2+(10)^2\times (-4))[/tex]

[tex]\frac{dV}{dt}=\frac{1}{3}\pi(400)=\frac{400}{3}\pi in^3/s[/tex]

Hence, the volume of cone changing at rate [tex]\frac{400}{3}\pi in^3/s[/tex]

Equation of a line:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope.

Finding the slope of a line, given two points:

When we are given two points of a line, the slope of the line is given by the change in y divided by the change in x.

Points (4,r), (r,3)

Change in y: 3 - r

Change in x: r - 4

Slope is 0, so:

[tex]\frac{3 - r}{r - 4} = 0[/tex]

[tex]3 - r = 0[/tex]

[tex]r = 3[/tex]

The value is r = 3.

Answer: 50%

Step-by-step explanation:

In 2010, there were only 2 bike manufacturers and they had market shares of 30% and 70%.

A new manufacturer joins the market and captures 10% of the market share and Splendor increases to 40% of market share.

Market shares:

Yamaha = 10%

Splendor = 40%

Passion = 100% - 10% - 40%

= 50%

Answer:

C. 66 mm (using 3.14, it would be 65.94 mm)

Step-by-step explanation:

From what I know, the radius of this coin is 10.5 mm.

The formula for the circumference of a circle is 2πr or πd.

In this case we're using 3.14 for π.

(2 * 10.5) * 3.14

21 * 3.14

21 * 3.14 is the same as 62.8 + 3.14

62.8 + 3.14

65.94 mm

This is close to 66 mm, which was C, so that is the answer.

Slope = change in Y over change in X:

Slope = (1 - 8) / (5-9)

Slope = -7/-4

Slope = 7/4

Answer:

The slope is [tex] \frac{7}{4} [/tex].

.

Step-by-step explanation:

Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

☆And now we just plug in!

[tex]m = \frac{1 - 8}{5 - 9} = \frac{ - 7}{ - 4} = \frac{7}{4} [/tex]

Answer:

x + y = 0

Step-by-step explanation:

x and y are both the same distance from 0 on the number line. That means they are additive inverses (or opposites). Knowing this law, additive inverses always equal 0.

Answer:

900 L

Step-by-step explanation:

Let x be the number of litres when the tank is full.

Then 5/6 x - 30 = 4/5 x

Solve this by converting to /30:

25/30 x - 30 = 24/30 x

1/30 x = 30

x = 30*30 = 900

The standard error of the sample mean is 0.7835140.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Given:

Population mean = 62.95

Population standard deviation = 5.65

Sample size = 52

The standard error of the sample mean :

= Standard deviation / √(sample size)

= 5.65 / √(52)

= 0.7835140

Hence, the standard error is 0.7835140.
