Answer:
y=sin((pi/290)x)
Step-by-step explanation:
If we look at all the coordinates given (0,0),(145,1),(290,0),(435,-1),(580,0) we can draw it out and see what are our maximum and minimum y-value. Once you graph this you will notice that the maximum y-value is 1 and minimum y-value is -1, this is important because we call this our amplitude. Now we will determine our midline, we do so by getting the average of our amplitude so
and so our midline is zero. Next we will determine our period in terms of radians we can do so by looking at our period which happens to be 580. This means that the line will repeat itself every 580 on the numberline and so:

Therefore our period in radians is pi/290.
A sine function is such that:

where A is the amplitude, B is the period, and D is the midline. Our amplitude is 1, midline is zero and our period is pi/290 and so our final equation is:

Answer:
10 lb of cashews and 70 lb of peanuts
Step-by-step explanation:
Let x = the pounds of cashews.
Then 80 – x = the pounds of peanuts
Value of cashews + value of peanuts = volume of mixture
x×4.75 + (80 – x)×2.75 = 80×3 Remove parentheses
4.75x + 220 - 2.75x = 240 Combine like terms
2.00x + 220 = 240 Subtract 220 from each side
2.00x = 20 Divide each side by 2.00
x = 10 lb
80 - x = 80 – 10
80 - x = 70 lb
Max will mix 10 lb of cashews with 70 lb of peanuts.

<em>Check:
</em>
10×4.75 + 70×2.75 = 80×3.00
47.50 + 192.50 = 240.00
240.00 = 240.00
