Answer:
(A)d=20h
Step-by-step explanation:
If Kia rides her bike at 20 miles per hour.
20 miles per hour is referred to as the Kia's Speed.
Now we know that:
Given:
- Number of hours traveled=h
- Distance traveled=d
- Speed = 20 mph
Substituting these three into the formula above, we have:
Cross multiply
d=20h
<u>The correct option is A.</u>
The exponential functions change is represented by decay and the percentage rate of decrease is 1.00619%.
Step-by-step explanation:
Step 1:
To determine if the function represents growth or decay, we substitute values to x.
If the values increase with an increase of x, it represents growth.
If the values decrease with an increase of x, it represents decay.
Step 2:
If
If
So as x increases the value of y decreases, so it represents decay.
Step 3:
The percentage rate of change is determined by dividing the difference of two consecutive values by the first value.
The percentage rate of change
Substituting the values, we get
The percentage rate of change .
As the values of y decrease with an increase in x, it is the percent decrease per unit.
