Answer: 8 meters per second
Step-by-step explanation:
Hi, to answer this, first, we have to divide the time counted by the number of waves, to obtain the time of each wave:
10 /20 = 0.5 seconds per wave
Now, we simply divide the distance given by the time, to obtain the speed rate:
4/0.5 = 8 meters per second

Answer:
(A) The slope of secant line is 18.
(B) The slope of secant line is h+16.
Step-by-step explanation:
(A)
The given function is

At x=3,

At x=9,

The secant line joining (3,27) and (9,135). So, the slope of secant line is


The slope of secant line is 18.
(B)
The given function is

At x=5,

At x=5+h,

The secant line joining (5,55) and
. So, the slope of secant line is



The slope of secant line is h+16.
