The mass of a particular substance is known to grow exponentially at a rate of 1.5% per day. its initial mass was 230 grams and, after t days, it weighed 325 grams.

the equation modelling this growth is

230×1.015 t  =  325.

use the method of taking logs to solve this equation for t, giving your answer correct to the nearest day.

23 days

Step-by-step explanation:

Given that the mass of a particular substance is known to grow exponentially at a rate of 1.5% per day

Initial mass =

After t days, mass =

The equation is

Approximately after 23 days the mass will become 325 gms.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
