Answer:
The rate at which Perimeter of the square is increasing is .
Step-by-step explanation:
Given:
Circumference of the circle =
Rate of change of in circumference = 6 in/secs
We need to find the rate at which the perimeter of the square is increasing
Solution:
Now we know that;
Now we know that;
side of the square= diameter of the circle
side of the square =
Now Perimeter of the square is given by 4 times length of the side.
Now we need to find the rate at which Perimeter is increasing so we will find the derivative of perimeter.
But
So we get;
Hence The rate at which Perimeter of the square is increasing is .
Answer: C, D
<u>Explanation:</u>
Length: L = x + 3
width: x ≥ y + 2 ⇒ y ≤ x - 2
wheels: y
0.50(L * x) + 4(2.25y) ≤ 50
0.50(x + 3)(x) + 4(2.25y) ≤ 50
0.50(x² + 3x) + 9y ≤ 50
9y ≤ 50 - 0.50(x² + 3x)
<u>9y</u> ≤ <u>50 - 0.50x² - 1.5x</u>
÷9 ÷9
y ≤

15 per person is the rate
22 is the constant
y = 15x + 22
<em>divide that by the number of people (x) to get:</em>
y =
