An electronics store finds that over a period of three months, sales of stereos decreased. In March, the store sold 325 stereos. In April, the store sold 280 stereos, and in May, the store sold 235 stereos. Type your answers and then click or tap Done. Make a conjecture about the number of stereos sold in June. Make a conjecture about the number of stereos sold in July. Make a conjecture about the number of stereos sold in August.

b.-4 units

all you   do is count how many times you move

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

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
