When using a quadratic equation in the form y = ax2 + bx + c to model the height of a projectile (y) over time (x), which of the following is always represented by the constant term?
the initial height of the projectile
the initial velocity of the projectile
the time at which the projectile hits the ground
the maximum height of the projectile
its not b , i already

The general form of a quadratic equation is .

We want to know what is meant by the constant term, c.

If we let x=0, we have y=c. What does this mean?

y is the height and x is time, so y=c at x=0 means at time 0, the height of projectile is c, or, the initial height of the projectile is c.

c, thus, is the initial height.

ANSWER: "the initial height of the projectile"

step-by-step explanation:

1+1=2

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
