Identify the variation as direct, inverse, joint or combined. y = cx²

combined variation          

Step-by-step explanation:

we have

we know that

a) in the interval ----> (0,∞)

If the value of x increase the value of y increase

so

Is a direct variation

b) in the interval ----> (-∞,0)

If the value of x increase the value of y decrease

so

Is a inverse variation

therefore

Is a combined variation

according to newton’s cannonball model, what happens if the cannonball's velocity is enough to overpower the pull of earth’s gravitystep-by-step explanation:

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.
