A nurse infuses a dose in 50 minutes. She needs to infuse the dose at a 20% faster rate. How much time does she need ?
1 answer:
Answer: The nurse needs 40 minutes to infuse the dose at a 20% faster rate.
Step-by-step explanation:
In order to calculate how much time the nurse needs to infuse the dose, you have to calculate how much is the 20%
The 20% of 50 minutes is obtained multiplying 50 by the factor that represents the 20% which is
= 10 minutes
Now, the time she needs to infuse the dose at a faster rate is obtained as follows:
50 minutes - 10 minutes = 40 minutes.
Notice that you have to subtract the 20% of 50 minutes to the original time to obtain a 20% faster rate.

<h3>The function for Bruce’s elevation isStep-by-step explanation:
We are given initial Bruce’s elevation = 1,505 feet.
Each successive hour, his average elevation change for the hike becomes 6 times the previous hourly elevation change.
We know, the exponential function , where a is the initial value, b is the growth factor and x is the exponent represents time in hours.
Therefore, initial value a=1505, growth factor b for exponential function is 6.
Plugging a=1505 and b=6 in , we get
Also note, if b>0, it would be an exponential growth function.
<h3>Therefore, the function for Bruce’s elevation is
