Answer
Exponential function is in the form of : 
.....[1]
where a is the initial amount and r is the growth rate and (1+r) is the growth factor.
Given the function: 
On comparing with equation [1] we have;
Initial amount(a) = 12
1+r = 1.05
Subtract 1 from both sides we get;
or 5%
Growth (r) = 0.05 or 5%
Now, evaluate the function for t = 5 we have;
Substitute the value of t=5 in the given function we have;
Therefore, the value of function when t=5 to the nearest tenth is 15.3
D 8x-3 because must add them all together
Answer:
Step-by-step explanation:
Given that,
The area of the base = 13.2 cm²
The height of the pyramid = 13.7 cm
We need to find the volume of this pyramid. The formula can be given by :
Put all the values,
So, the volume of the pyramid is equal to 
.
I'm not an economic expert, but this looks like (y=my+b) where b is the y intercept which is where a graph crosses the y axis. In your case if F=0 then your graph will cross at the origin. IF it is a similar concept.
