Afree floating bubble had a diameter between 41 and 42 feet. calculate the exact volume of a sphere with a diameter of 42 feet( type an exact answer in terms of pi)

$18 was the price of the t-shirt

step-by-step explanation:

a .4y4

hope this !

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
