We have been given that a virus has infected 400 people in the town and is spreading to 25% more people each day. We are asked to write an exponential function to model this situation.
Since the number of infected people is increasing, so our model will be exponential growth model.
An exponential growth function is in form , where,
y = Final amount,
a = Initial amount,
r = Growth rate in decimal form,
x = Time.
Let us convert 25% into decimal form.
The initial number of infected people is , so our function would be .
To find the number of infected in 10 days, we will substitute in our given formula as:
Therefore, there will be approximately 3725 infected people in 10 days.

Answer:
The graph of image and preimgae is shown below.
Step-by-step explanation:
From the given figure it is noticed that the vertices are A(-2,2), B(5,2), C(5,0), D(0,0), F(0,-2) and G(-2,-2).
It is given that figure ABCDFG is rotated by positive 90° about the origin (0,0).
Positive means counter clockwise and negative means clockwise.
If a figure is rotated by counter clockwise 90° about the origin (0,0), then
The vertices of image are
The graph of image and preimgae is shown below.
