For

you seem to want to know the value of f(0). Put 0 where x is, then evaluate.
The initial value of the function is 3._____
You will observe that when x=0, the exponential term evaluates to 1. This is true regardless of its base. Thus f(0) is always the coefficient of the exponential term—in this case, 3.
Answer: Well since the ratio is 9:7 for red to blue well transfer that first by finding out the blue if there are 117 xc=9:7x13 would be 117 red and 7x13=91 blue so the new ratio is 117:91.
So now we add which I'm sure you can do,
117

The dimensions of the prism are 3 m by 4 m by 5 m.
Area = 2(3 * 4 + 3 * 5 + 4 * 5) = 2(12 + 15 + 20) = 2(47) = 94 m^2
7:4 is the original ratio.
Apples to oranges
14:x
7*2 = 14
4*2 = 8
14:8
Answer: There are 8 oranges
