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

. In April, it rained 1/4 of an inch on 15 different days. How many inches of rain fell
notka56 [123]

Answer:

3.75, or \frac{15}{4} inches of rain during the 15 days of April.

Step-by-step explanation:

All you have to do is add \frac{1}{4} 15 times to get that number.

\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} +\frac{1}{4} = 3.75

You can also do 15 times \frac{1}{4}, which will result in the same thing.

Answers matching "The combined average weight of an okapi and a llama is 450 kilograms. The average weight of 3 llamas is 190 ki
kirill [66]

Let us say that:

x = weight of llamas

y = weight of okapi

 

From the problem, we can create the equations:

x + y = 450           --> 1

3 x = y + 190        --> 2

 

Rewriting equation 1:

x = 450 – y

 

From equation 2:

3 (450 – y) = y + 190

1350 – 3 y = y + 190

4 y = 1160

y = 290

 

From equation 1:

x = 450 – 290

x = 160

 

Therefore a llama weighs 160 kilograms while okapi weigh 290 kilograms on average.
