Daniel is in the buisness of repairing home computers. He charges a base fell of $30 for each visit and $15 per hour for his labor. Write a function for the total cost c(h) for a home visit and h hours of labor

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
