Answer:
It will take 47 hours
Step-by-step explanation:
We can have the exponential function as follows;
P = I( 1 + r)^n
if the initial value was x , the final will be 2x
The change rate is 1.5% , which is r, this is same as;
1.5/100 = 0.015
So what we want to calculate is the n attached
This will be;
2x = x ( 1 + 0.015)^n
2 = 1.015^n
ln 2 = n ln 1.015
n = ln 2/ln 1.015
n = 46.55
This is approximately 47 hours
Answer:
The product would be -27x.
Step-by-step explanation:
First you use the distributive property to distribute the -9x to the 5 and the -2x. Then you would get -45x+18x. 18x because when you multiply a negative and a negative you get a positive. Then, you add those two and you should get -27x.
