Question

A few weeks into the deadly SARS (Severe Acute Respiratory Syndrome) epidemic in 2003, the number of cases was increasing by about 4% each day.† On April 1, 2003 there were 1,804 cases. Find an exponential model that predicts the number
A(t)
of people infected t days after April 1, 2003.
A(t) = 1804(1.04^t)
Use your model to estimate how fast the epidemic was spreading on April 17, 2003. (Round your answer to the nearest whole number of new cases per day.

Answer 1

just plug in the number of days that had past to get your answer

Answer 2

I did and I got 3,378.85 but its says to round to the nearest whole number and therefore its 3,379 cases per day, but my homework is online and its says its wrong

Answer 3

try this
1804(1.04^17)=3,517.8

Answer 4

i mean this
3518

Answer 5

still wrong

Answer 6

the nearest whole number means no decimal

Answer 7

ok try 3379

Answer 8

oh nm

Answer 9

yep i put 3518 and 3379 and still wrong

Answer 10

3379 doesnt work either

Answer 11

oh i think i got it.
3514

Answer 12

nope hahaha

Answer 13

@igreen we need help

Answer 14

What does 't' represent? Days?

Answer 15

yes

Answer 16

\(A(17) = 1804(1.04^{17})\)

\(A(17) = 1804(1.9479005)\)

\(A(17) = 3514.0125\)

Answer 17

17 days is approximately $3,514.

Answer 18

I get that when I graph too..

Answer 19

3,514 or 3,513

Answer 20

@iGreen nope he already tried 3514

Answer 21

Maybe $3,513 will work.

Answer 22

hopefully.

Answer 23

nope
