The volume is proportional to the cube of the radius:
4^3=64
The volume will be 64 times the original value!
Answer:
x= -5
Step-by-step explanation:
just use a calculator
(x+13)*(x-7)=0
Split into possible cases :
________________________
x+13=0
x-7=0
Solve the equations:
________________________
x= -13
x= 7
Final solution :
According to the rate of change, it is found that the hourly rate of temperature change at the bottom of the mountain was of -2.5 ºC per hour.
<h3>What is the average rate of change?</h3>
The average rate of change of a function is given by the <u>change in the output divided by the change in the input.</u>
In this problem, it is stated that at the top of the mountain, the average rate of change is of -2.5 ºC per hour, and at the bottom of the mountain the rate is the same, hence the hourly rate of temperature change at the bottom of the mountain was of -2.5 ºC per hour.
