Answer a = 5 and b = 2.
Procedure
Initially means x = 0, then
5 = a*b^0 = a*1 = a, then a = 5
When x = 1, the height is the double of 5, i.e 10 and
10 = a.b^1 = a.b ⇒ b = 10/a = 10/5 = 2
The a = 5 and b = 2, so the equation is y =5(2)^x
Answer:
Step-by-step explanation:

In this situation a = 1, b = 2

1 + 4 = 
5 = 
c = 
This is an important mathematical theorem to know. It's called the Pythagorean Theorem.
Put the argument value where the variable is, then evaluate.
For f(x), you want f(2).
f(2) = 2² + 1 = 4+1 = 5
For g(x), you want g(1).
g(1) = 3·1 +1 = 4
For [f(2) - g(1)] you want the difference of the above values.
[f(2) - g(1)] = [5 - 4] = 1
Answer: 17.28
Step-by-step explanation:
18*12 =216*.02=4.32
18*12=216*.10=21.6
21.6-4.32=17.28
