Answer:
The rate of change is
ft^(2)/min
Step-by-step explanation:
The area of a circle is given by the following equation:

To solve this question, we have to realize the implicit differentiation in function of t. We have two variables, A and r. So

We have that:
.
We want to find 
So


Since the area is in square feet, the rate of change is in ft^(2)/min.
So the rate of change is
ft^(2)/min
The absolute value of -1/3 is 1/3. I guess by using the number line you move 2(1/3) to the right from the point -1/3
The answer is 42.3
Step by Step:
Let our variable be n, standing for number.
3.6(x) + 4.5(y) = n
3.6(3) + 4.5(7) = n
10.8 + 31.5 = n
n = 42.3
Answer:
The measure of the complement angle is 
Step-by-step explanation:
Let
x-----> the angle
we know that
The complement of an angle is equal to 
The supplement of an angle is equal to 
we have
The complement of an angle is one-sixth the measure of the supplement of the angle

solve for x




Find the measure of the complement angle
