The equation will be of the form:

where A is the amount after t hours, and r is the decay constant.
To find the value of r, we plug the given values into the equation, giving:

Rearranging and taking natural logs of both sides, we get:


The required model is:
For 24 keep the orders of operation in mind. So first we'd work out what's in parentheses, so we'd start by doing 5-3, which is 2. We'd then add 2+2 to get 4. Then we multiply 16 and 4 to get 64. So the correct answer is 64.
For the second part of 24 we first multiply 3 and 4 to get 9. We would then subtract 17-9 to get 8. Finally, we'd add 8+2 to get 10. So the correct answer is 10.
As for 25, the answer is 6400 centimeters^3.

Hello! Your figures are missing, so I could help you in a general way. The Slope-intercept form of the equation of a line is given by the form:

Case 1:

If the slope is positive, we will have a line as the form illustrated in figure 1. So as x increases y also increases.
Case 2:

If the slope is negative, we will have a line as the form illustrated in figure 2. So as x increases y decreases.
Case 3:

If the slope is zero, we will have a line as the form illustrated in figure 3. here we have a constant function.
Case 4:
m: undefined
If the slope is undefined, we will have a line as the form illustrated in figure 4.
