George shouldn't think too far.
He should use the formula for Compound Interest.
Amount in compound interest, A = P(1+ r/100)ⁿ.
Where A = Amount, P = Principal, r is the rate per year, n = number of years.
Note: the expression (1+ r/100) is raised to power n.
From George's problem: P = 750, r = 22, I guess number of years , n = x
A(x) = 750( 1 + 22/100)ˣ
A(x) = 750( 1 + 0.22)ˣ
From your options I can't see an answer. Except the expression of option (A) is actually raised to power x, and not times x as stated in the option.

nope
Answer:h(x)=g(x+5)+1
Step-by-step explanation:
Right side of the equation:
cos ( A - B ) - cos ( A + B ) =
= cos A cos B + sin A sin B - ( cos A cos B - sin A sin B ) =
= cos A cos B + sin A sin B - cos A cos B + sin A sin B =
= 2 sin A sin B - left side of the equation ( correct )
The formula for exponential growth is written as y = a(1 + RATE)^time
where a is the starting value, rate is the percentage of growth written as a decimal and time in this case would be the number of days.
You are given the growth rate as 11% and the starting day was day 1.
Since the table only goes to 10 days, you can use 10 as the time, or use X as an exponent if you need to calculate more than 10 days.
Using all this information, the formula becomes y = 1(1.11)^10 for 10 days or y = 1(1.11)^x for any number of days needed.
