Can someone please explain how to go the answers for this
Effectus [21]

Answer:

A=3, B=4, C=-5

Step-by-step explanation:

So A represents the amplitude, which is the distance between the midline (C), the middle of the graph, and the maximum (or minimum). B is the distance of the period of the graph. In this case, we see that the midline is C=-5 because that is the halfway point of the sine function. We also see that the period distance is B=5-1=4, so our period would be 2π/4 or π/2. Our amplitude would be A=3 because |a|=|-5-(-2)|=|-5+2|=|-3|=3. Observe the graph to see this visually.

MatroZZZ [7]

Answer:

slope = -1/2 and y-intercept = 80

Step-by-step explanation:

A water tank has 80 gallons of water. But the tank has a leak from which water flows at a rate of 1 gallon every 2 minutes

Rate of change is the slope

Given that rate of change is  1 gallon every 2 minutes that is 1/2. The water flows out at the rate of 1/2. since it flows out the slope is negative.

So slope = -1/2

y intercept is the initial amount of water in the tank

A water tank has 80 gallons of water. so y intercept is 80 gallons of water

y intercept = 80
