Answer:
Step-by-step explanation:
<u>Differentiation</u>
We have a relationship between x and y as follows:
Both variables depend on time t for t≥0.
Differentiating with respect to time:
Applying the derivative of a power function:
Recall the derivative of a constant is 0.
Dividing by 2:
Solving for y':
At some specific time, we have:
x=3, y=4, dx/dt = x' = 6. Substituting:
Operating:
Simplifying:
Answer:
Now if the high and low monthly average temperatures satisfy the inequality, then the , monthly averages are always within 22 degrees of 43°F.
Step-by-step explanation:
The inequality describes the range of monthly average temperatures T in degrees Fahrenheit at a certain location.
The inequality expression is given as:
now this expression could also be expressed as:
Now if the high and low monthly average temperatures satisfy the inequality, then the , monthly averages are always within 22 degrees of 43°F.
( As the difference is 22 degrees to the left and right)
