M is directly proportional to r^3

Oliga [24]

Answer:

<em>r=6</em>

Step-by-step explanation:

<u>Proportions </u>

We know M is directly proportional to $r^3$

This can be written as

$M=kr^3$

Where k is the constant of proportionality which will be determined knowing that when r = 4, M= 160. Substituting in the equation above:

$160=k\cdot 4^3$

$160=k\cdot 64$

Solving for k:

$k=\frac{160}{64}=2.5$

The equation is:

$M=2.5\cdot r^3$

Now find r when M=540:

$540=2.5\cdot r^3$

Dividing by 2.5:

$216=r^3$

Taking cube roots:

$r=\sqrt[3]{216}$

r=6

Pamela makes cloth dolls, which she sells to friends and relatives. her total inventory includes over 200 yards of fabric, 100 y

Tresset [83]

The number of items in her finished goods inventory would be the number of dolls that are complete. This would be 15 dolls. The other numbers represent items that are unfinished.

Which is true about the slope of the function y=4x+3?

$\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}$

The slope of the function y=4x+3 is 4; in equations like this one, the slope is simply the number before x.

The rise is 4, and the run is 1.

Remember, slope is also defined as "Rise/Run"

[Note:- You haven't listed any options here, could you kindly add them in the comments?]

<h3>Good luck.</h3>

Determine the slope of the line represented by y=5x-7 ?

Reptile [31]

Step-by-step explanation:

that is totally easy.

in the slope intercept form of a line equation the factor of x is always the slope.

in general

y = ax + b

a = the slope.

so, in our case here

y = 5x - 7

5 is the slope.

and -7 is the y intercept (at what point does the line intercept the y-axis; that is the y value when x = 0).
