Answer: The formula to calculate the radius of a sphere if we know the volume is: Cubic root [3V/(4∏)].


Solution:

The formula for the volume (V) of a sphere is:

V=(4∏/3) r^3

Solving for r: Multiplying both sides of the equation by 3/(4∏):

3/(4∏) V = 3/(4∏) [(4∏/3) r^3]

3V/(4∏) = r^3

Cubic root both sides of the equation (raising to the power 1/3):

Cubic root [3V/(4∏)] =Cubic root (r^3)

Cubic root [3V/(4∏)] = r

r = Cubic root [3V/(4∏)]

A lines slope is 0, and it’s y intercept is 3. What is it’s equation in slope intercept form?
Zepler [3.9K]

Answer:

y=3

Step-by-step explanation:

y=mx+b where m = slope and b=y-intercept
slope: 0, y-intercept: 3

Eva has borrowed 200 songs from her friend. She plans to download an equal number of songs on her music player each week for 5 w
Alenkasestr [34]

PART A)

The rate of change is -40 songs each week, because the amount of songs left to be downloaded decrease by 40 every week.

<span>the initial value is 200 at 0 weeks, which means that there are 200 songs to be downloaded at the beginning</span>

PART B)

<span><span><span> <span><span>calculate the slope:
</span><span> m = (y2- y1)/(x2 - x1) = (160 - 200)/(1 - 0)
m = -40
now use the line equation in form of point-slope
y - y1 = m(x - x1)
y - 200 = -40(x - 0)
y = -40x + 200</span></span> </span></span></span>

Answer: 9


Step-by-step explanation:

To square a number, you multiply it by itself twice.

In this case, your answer would be 3 x 3 = 9.

Hope it helps! :)
