Okay. 12 - 4 is 8. For the other question, you have to multiply the difference of that by 1/4. 8 * 1/4 is 2. The expression of (12 - 4) is four times the value of 1/4 * (12 - 8). and 2 is 1/4 the value of 8. The answers to this question are A , B, and C.
Repost your question. There is clearly a typo on the right side.
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.

supplementary angles are 180°
<1+<2=180°
given that <1=112°
112°+<2=180°
<2=180°-112°
<2=68°
