The ebola virus has an infection rate of 11% per day as compared to the sars virus, which has a rate of 4% per day. if there were one case of ebola and 30 cases of sars initially reported to the authorities and cases are reported each day, which statement is true?

3) At day 10 there are more SARS cases, but at day 53 there are more Ebola cases.

Step-by-step explanation:

First let's get our variables.

Ebola Rate = 11% or 0.11

SARS Rate = 4% or 0.04

x = number of days

Let Ebola = e(x)

Let SARS = s(x)

So the total number of cases  are:

e(x) =

s(x) =

At day 10:

e(10) =

e(10) =

e(10) =

s(10) =

s(10) =

s(10) =

So at day 10 the number of cases of Ebola will be 2 and SARS at 44.

At day 53:

e(53) =

e(53) =

e(53) =

s(53) =

s(53) =

s(53) =

By day 53, Ebola will overtake SARS at 252 cases to 239 cases.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
