The distance traveled, in feet, of a ball dropped from a tall building is modeled by the equation d(t) = 16t2 where d equals the
nignag [31]

Assuming that by "16t2" you mean 16t^2:


First of all, let's compute the position at the two required times:


d(2)=16\cdot 2^2 = 16*4 = 64


d(5)=16\cdot 5^2 = 16*25 = 400


So, the ball traveled a total distance of \Delta d = 400-64 = 336, during the time \Delta t = 5-2 = 3.


The average rate of change is the ratio between these two:


\frac{\Delta d}{\Delta t} = \frac{336}{3} = 112

What is the value of x?
Alexus [3.1K]

Answer:

x = 22.5

Step-by-step explanation:

\frac{BH}{DH}  =  \frac{HM}{HT}  \\  \frac{6}{15 + 6}  =  \frac{9}{9 + x}  \\  \frac{6}{21}  =  \frac{9}{9 + x}  \\ 6(9 + x) = 9 \times 21 \\ 54 + 6x = 189 \\ 6x = 189 - 54 \\  6x = 135 \\ x =  \frac{135}{6}  \\ x = 22.5
