Answer: A.
B. A'(5) = 1.76 cm/s
Step-by-step explanation: <u>Rate</u> <u>of</u> <u>change</u> measures the slope of a curve at a certain instant, therefore, rate is the derivative.
A. Area of a circle is given by
So to find the rate of the area:
Using
Then
Multipying and simplifying:
The rate at which the area is increasing is given by expression .
B. At t = 5, rate is:
At 5 seconds, the area is expanded at a rate of 1.76 cm/s.
C because PEMDAS

In parallelogram SAVE, the value of the angle is m∠SEV = 125° while in parallelogram MORE ∠MOR = 111
<h3>What is a
parallelogram?</h3>
A parallelogram is a quadrilateral with equal opposite and parallel sides. Opposite angles are equal.
In parallelogram SAVE:
m∠VAS = m∠SEV
3x - 5 = 2x + 15
x = 20
m∠VAS = 3(20) - 5 = 55 degrees
m∠VAS + m∠SEV = 180 (consecutive interior angles)
55 + m∠SEV = 180
m∠SEV = 125°
In parallelogram MORE:
∠MOR + ∠ORE = 180 (consecutive interior angles)
4x - 5 + 2x + 11 = 180
x = 29
∠MOR = 4(29) - 5 = 111
In parallelogram SAVE, the value of the angle is m∠SEV = 125° while in parallelogram MORE ∠MOR = 111

26.5×.006=value, so you take value ans subtract from 26.5.
The length of the diagonal of the square is 22.05 units
<h3>How to find the diagonal of a square?</h3>
A square have all its sides equal to each other.
Therefore, using Pythagoras theorem,
c² = a² + b²
c² = (9√3)² + (9√3)²
c² = 81 × 3 + 81 × 3
c² = 243 + 243
c² = 486
square root both sides
c = √486
c = 22.045407685
c = 22.05 units
