Answer:

3.  [tex]\dfrac{4}{3 \pi}[/tex]

Step-by-step explanation:

Volume of a cone:

[tex]V=\dfrac13\pi r^2h[/tex]

(where r is the radius and h is the height)

Given:

[tex]\implies r=\dfrac14h[/tex]

Therefore, substitute [tex]r=\frac14h[/tex] into the volume formula to find the volume of the cone in terms of h:

[tex]\implies V=\dfrac13\pi \left(\dfrac14h\right)^2h[/tex]

[tex]\implies V=\dfrac{1}{48}\pi h^3[/tex]

Differentiate with respect to h:

[tex]\implies \dfrac{dV}{dh}=3 \cdot \dfrac{1}{48} \pi h^2=\dfrac{\pi h^2}{16}[/tex]

Volume is increasing at a constant rate of 3cm/s:

[tex]\implies \dfrac{dV}{dt}=3[/tex]

Use the chain rule to find [tex]\dfrac{dh}{dt}[/tex]

[tex]\implies \dfrac{dh}{dt}=\dfrac{dV}{dt}\times\dfrac{dh}{dV}[/tex]

[tex]\implies \dfrac{dh}{dt}=3\times\dfrac{16}{\pi h^2}[/tex]

[tex]\implies \dfrac{dh}{dt}=\dfrac{48}{\pi h^2}[/tex]

When h = 6:

[tex]\implies \dfrac{dh}{dt}=\dfrac{48}{\pi \cdot 6^2}=\dfrac{4}{3 \pi}[/tex]

Step-by-step explanation:

Answer:

x=-5

Step-by-step explanation:

-12x-7=53

     +7=+7

-12x=60

divide both sides by negative 12

60/-12= -5

so x =-5

The solution of the linear equation with a single variable - 12x - 7 = 53 will be -5.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The equation with a single variable 'x' is given below.

- 12x - 7 = 53

Simplify the equation, then we have

- 12x - 7 = 53

- 12x = 60

x = 60 / (-12)

x = - 5

The solution of the linear equation with a single variable - 12x - 7 = 53 will be -5.

The measure of center that would best describe a typical value of the data set is a mean since the values are close.

It should be noted that the measure of center include the mean, median, mode, and the mid-range.

In this case, when there is a close distribution of different numbers, he beta measurement will be the mean.

Therefore, the mean of the numbers will be:

= (20 + 21 + 21 + 25 + 20 + 23 + 27 + 23 + 24 + 25 + 26 + 24 + 23 + 22 + 24)/15

The length of segment YT will be equal to 12 units as the line segment XY is dilated to create line segment X'Y' using point t as the center of dilation.

Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

Triangles XYT and X'Y'T are similar to the AA Similarity Theorem

[tex]\dfrac{XT}{YT}=\dfrac{X'T}{Y'T}[/tex]

substitute the given values

[tex]\dfrac{8}{YT}=\dfrac{6}{9}[/tex]

[tex]YT=\dfrac{9\times 8}{6}[/tex]

[tex]YT=12\ units[/tex]

Hence the length of segment YT will be equal to 12 units as the line segment XY is dilated to create line segment X'Y' using point t as the center of dilation.

to get the slope of any straight line, we simply need two points off of it, hmm from the table let's use hmmm (2 , 0) and (4 , -2)

[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-2}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-2}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{4}-\underset{x_1}{2}}}\implies \cfrac{-2}{2}\implies -1[/tex]

Step-by-step explanation:

To find the slope, take 2 points from the graph. I'm going to pick (0,2) and (1,1). Whenever we find the slope this way, we need to keep this formula in mind:

[tex] \frac{y2 - y1}{x2 - x1} = slope[/tex]

Solution:

Numbers with a negative sign are less than zero

Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.

+ sign numbers can be denoted as simply numbers  

On a number line the number increases as we move to the right and decreases as we move to the left.
