The number of students is an illustration of a linear function
There are 1320 students in branch B
<h3>How to determine the number of students</h3>
From the question, we have the following equation that represents the number of students in branch A
A = 1650
Also, we have:
Multiply through by 4
Add 4B and B
Substitute 1650 for A
Divide through by 5
Hence, there are 1320 students in branch B

Answer:
8πcm²/sec
Step-by-step explanation:
The radius of the circle increases at a rate of dr/dt = 0.25cm/sec
The radius of the circle r = 16cm
The area of the circle increases at a rate of dA/dt = ?
Area of a circle = πr²
We take the derivative with respect to t
dA/dt = 2πrdr/dt
dA/dt = 2 π (16)(0.25)
dA/dt = 8πcm²/sec
