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.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
