Answer:

The radius of the sphere is 6\ cm

Step-by-step explanation:

we know that

The volume of a sphere is equal to

V=\frac{4}{3}\pi r^{3}

In this problem we have

V=288\pi\ cm^{3}

substitute and solve for r

288\pi=\frac{4}{3}\pi r^{3}

simplify

288*3/4=r^{3}

r^{3}=216

r=6\ cm

5x-2y=2 slope intercept form?
Nata [24]

Answer:

y = \frac{5}{2}x-1  

Step-by-step explanation:

Slope-intercept form is represented by the formula y = mx  + b. So, to place the given equation in slope-intercept form, isolate the y on the left side and arrange the terms in that matching order. Remember, whatever you do to one side, do to the other:

5x-2y = 2\\-2y = -5x + 2\\\frac{-2}{-2}y = \frac{-5}{-2} x+\frac{2}{-2} \\y = \frac{5}{2} x-1

So, the slope-intercept form is y = \frac{5}{2}x-1.

Find the measure of the indicated angle to the nearest degree.
eimsori [14]

1. use sin

inverse of sin(44/57) = 50.5 ---> 51°

2. use tan

inverse of tan(6/8) = 36.8 ---> 37°

3. use cos

inverse of cos(20/31) = 49.8 ---> 50°

4. use sin

inverse of sin(37/58) = 39.6 ---> 40°
