The number of people with the flu during an epidemic is a function, f, of the number of days, d, since the epidemic began. The equation f(d) = 50 - ()" defines f.

a. How many people had the flu at the beginning of the epidemic? Explain how you know.

b. How quickly is the flu spreading? Explain how you can tell from the equation.

c. What does f(1) mean in this situation?

d. Does f(3.5) make sense in this situation?

answer: this is not a question

step-by-step explanation: this is a answer

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.

first, let's see what the pattern is.

58 - x = 47

46 - x = 36

x = 9

so this means that the term after 25 is 25 - 9:

the next term in the sequence is 16.
