The graph of the sine curve below is of electromagnetic energy that represents green light: sine graph with points at 0, 0 and 145, 1 and 290, 0 and 435, negative 1 and 580, 0 what function accurately represents the sine curve for green light?

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: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
