The area of the square increasing at 30 
The rate of change function is defined as the rate at which one quantity is changing with respect to another quantity. In simple terms, in the rate of change, the amount of change in one item is divided by the corresponding amount of change in another
Let the side of a square be x.
So,
Area of square = 
A =
Differentiating with respect to time we get,
dA/dt = 2x dx/dt
When area = 9
the side becomes 3 cm
At x = 3cm and dx/dt = 5 cm/s (Given)
dA/dt = 2.3.5 = 30 
Thus the area of the square increasing at 30

A linear equation in two variables doesn't involve any power higher than one for either variable. It has the general form Ax + By + C = 0, where A, B and C are constants. It's possible to simplify this to y = mx + b, where m = ( −A / B) and b is the value of y when x = 0. A quadratic equation, on the other hand, involves one of the variables raised to the second power. It has the general form y = ax2 + bx + c. Apart from the adding complexity of solving a quadratic equation compared to a linear one, the two equations produce different types of graphs.
The point (250,0) of the graph represents that the average price per ticket is $250.
Given to us
x is the price the passenger paid
f(x) is the positive percent difference
<h3>What is the correct interpretation of the point (250, 0)?</h3>
We know that a coordinate is written in the form of (x, y), therefore, the point (250, 0) represents that the price of the ticket is 250, while the 0 in the coordinate represents that there is no percentage difference. Since the point (250,0) is the mid-value of the x-axis on the graph, we can say that $250 is the average price of the ticket.
Hence, the point (250,0) of the graph represents that the average price per ticket is $250.

Answer:
Step-by-step explanation:
A)
attached , I used g o o g l e draw.
B)
0.8 m = 80 cm =800 mm /50 = 16 mm
C)
bed = 4cm x 3cm
4cm*50= 200 cm = 2 m
3cm*50 = 150 cm = 1.5 m
