The table shows the height of a soccer ball that has been kicked from the ground over time. (For reference: h(t) = 144 – 16t2) T
adoni [48]

Answer : option D

The rate of change is not constant and increases then decreases over time. The height of the ball above ground gets larger until 1.25 seconds and then gets smaller after that time.

Rate of change is nothing but the slope

To find slope we use formula \frac{Change in height }{change in time}

Time (seconds) Height (feet) Rate of change

0 -------------------------0

0.5 -----------------------16 --------------------\frac{16-0}{0.5-0} =32

1 ----------------------24 --------------------\frac{24-16}{1-0.5} =16

1.25 -----------------------25--------------------\frac{25-24}{1.25-1} =4

1.5 -------------------------24 --------------------\frac{24-25}{1.5-1.25} =-4

2 ----------------------------16 --------------------\frac{16-24}{2-1.5} =-16

2.5 -------------------------0 --------------------\frac{0-16}{2.5-2} =-32

Rate of change is positive till 1.25 seconds and then it becomes negative. From this it is clear that, the rate of change is not constant and increases then decreases over time. The height of the ball above ground gets larger until 1.25 seconds and then gets smaller after that time.

A dinner plate has a circumference of 106.76 cm. What is the area of the dinner plate? Use = 3.14.
Sphinxa [80]
C=2pr,  r=c/(2p)

a=pr^2, using r found above we get:

a=p(c^2/(4p^2))

a=(c^2)/(4p), since c=106.76 and we approximate pi as 3.14

a=(106.76^2)/(4*3.14)

a=11612.2176/12.56 cm^2

a≈924.54 cm^2  (to nearest one-hundredth of a square cm)
