Answer:
Step-by-step explanation:
I believe the correct answer from the choices listed above is option D. The expression that could be used to determine the average rate at which the object falls during the first 3 seconds of its fall would be (h(3)-h(0))/3. Average rate can be calculated by the general formula:
Average rate = (change in y-axis) / (change in x-axis)
In this case,
Average rate = (change in height) / (change in time)

Step-by-step explanation:
the arc length of a circle is calculated as
arc = circumference of circle × fraction of circle
(5)
circumference (C) is calculated as
C = 2πr ( r is the radius )
here diameter = 12 , then r = 12 ÷ 2 = 6
C = 2π × 6 = 12π ≈ 37.7 m ( to the nearest tenth )
(6)
JK = 2πr × 
= 2π × 7 × 
= 14π × 
=
≈ 9.2 in ( to the nearest tenth )
(7)
7.5 = 2πr ×
7.5 = 2πr ×
( multiply both sides by 3 to clear the fraction )
22.5 = 2πr ( divide both sides by 2π )
r =
≈ 3.6 ft
