It gets you closer to your answer.
Ex: 11×2-- Round 11 to 10 and then multiply and get 20. But if you get some answer like 50, you know it is wrong. But the answer is 23
The second one since the lowest y value is -4 and the values go forever up
The <em><u>correct answer</u></em> is:
46.6 days
Explanation:
The general form for exponential growth is
, where A is the total amount, p is the initial amount, r is the percent of growth, and t is the amount of time (in this case, days).
We do not know the initial amount, the total amount, or the amount of time. We do know that r, the percent of growth, is 1.5%; 1.5% = 1.5/100 = 0.015:

We also know we want the total amount, A, to be twice that of the initial amount, p:

Divide both sides by p:

Using logarithms to solve this,

First u divide 39.39 to 3 and u get 13.13 so it is already rounded u dont need to round<span />
Answer:
3 3/4
Step-by-step explanation: all that you have to do is add 1/3 +2/3+11/4 which gives you 3 3/4
