A circle with a circumference of 108 cm is centered at the vertex of an angle. The rays of the angle subtend an arc that is 18.9 cm long. Complete the following statements by entering numbers in the answer boxes. a. 1/360th of the circumference of the circle is cm long, so the measure of the angle in degrees is
b. The arc subtended by the angle's rays is % of the circumference of the circle.

450 is the final answer! : )

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

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

it is c!

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
