Method 1

10%     -  43    |multiply both sides by 10

100%  -   430

Answer: 43 is 10% of 430.

Method 2

10%      -    43
100%    -    x
/cross multiply/

10x = 100·43
10x = 4300    |divide both sides by 10
x = 430

Answer: 43 is 10% of 430.

The correct option will be the last one: f(x)= 9sin(6 \pi x)+6

<em><u>Explanation</u></em>

The general equation for sinusoidal function is: f(x)= Asin(2\pi fx)+b, where A=Amplitude, f= frequency and b= y-intercept

Here the maximum value is 15 and the minimum value is -3. So, the distance between maximum and minimum values is 18. That means, the Amplitude, A= \frac{18}{2}=9

Frequency (f) is given as 3 and y-intercept(b) is 6

So, the required function will be:

f(x)= 9sin(2\pi*3x) +6\\ \\ f(x)= 9sin(6\pi x) +6
