Neither all can be substrates
(3x - 8y + 7)-(-x + 7y - 6)
The formula is V=1/3area of base*high
v=1/3*πr^2*h
=1/3*49π*9=49π*3=147πcm^3
a is the correct answer
The 1st number is odd, less than 5, so it might be 1 or 3, the probability is 2/10
But if the sum has to less than 5, than *when 1st number is 1, the second number can only be 1.2.3
and *when 1st number is 3, 2nd can only be 1
*1: 3/100
*2: 1/100
3/100+1/100=4/100
so the answer should be (4/100)/(2/10)=2/10=1/5
I'm not so sure if I'm right
plz tell me if there's something wrong with my answer
The average profit of the local store is an illustration of an exponential function
The profit function is: 
<h3>How to determine the function</h3>
From the question, we have:
- Initial value (a) = 960
- Rate per year (b) = 88%
An exponential function is represented as:

So, the function that represents the profit per year is:

Divide x by 12 to get the monthly rate

Evaluate the exponent

Hence, the profit function is:
