Question

On April 1st there were 5984 Covid 19 cases recorded in WA state. And on April 30th there we 14637 cases.

Let April 1st 2020 be represented by t=0 and thus April 30th which is 29 days later, is represented by t=29

Assume exponential growth Use this data to estimate the confirmed cases of Covid 19 in Wa state on May 15 2020(43 days after april 1st)

Number of cases based on exponential model =

Answer 1

Hello Sufyan,

First put the information into a table.

t (days) 0 29 43

y cases 5984 14637 ?

The method to find an equation in y and t depends on how your teacher wants you to do it.

You could substitute the first two points into an exponential equation such as y = Ce^kt

This will enable you to find the values of C and k. Then write the equation for y and t with the numbers for C and k. After that you can substitute 43 in for t and solve for y.

It is also possible to get an exponential equation using a graphing calculator. It will not have e as the base.

YOn TI-83 or 84, you would press STAT and choose Edit. Type in the firs two points into the columns.

Then Press STAT and highlight Calc. Choose expreg and Enter and it will give you a formula.

After that, you can substitute 43 for x, and solve for y.

After you work out the answer, you may submit your exponential formula and the final answer, and an Expert can check them.
