for a quadratic equation function that models the height above ground of a projectile, how do you determine the maximum height,

y, and time, x , when the projectile reaches the ground A) the maximum height is the y coordinate of the vertex of the coordinate function which occurs when x= b/2a the projectile reaches the ground when the height is zero. The time when this occurs is the x-intercept of the zero of the function that is farthest to the left. B) The maximum height is the y coordinate of the vertex of the equation function which occurs when x = b/2aThe projectile reaches the ground when the height is zero. The time when this occurs is the x-intercept of the zero of the function that is the farthest to the right. C) The maximum height is the y coordinate of the vertex of the quadratic function which occurs when x = -b/2a The projectile reaches the ground when the height is zero. The time went this occurs is the x-intercept of the zero of the function that is the farthest to the left. D) The maximum height is a y coordinate of the vertex of the quadratic function, which occurs when x = -b/2a the projectile reaches the ground when the height is zero. The time when this occurs is the x-intercept of the zero of the function that is farthest to the right.

Problem

For a quadratic equation function that models the height above ground of a projectile, how do you determine the maximum height, y, and time, x , when the projectile reaches the ground

Solution

We know that the x coordinate of a quadratic function is given by:

Vx= -b/2a

And the y coordinate correspond to the maximum value of y.

Then the best options are C and D but the best option is:

D) The maximum height is a y coordinate of the vertex of the quadratic function, which occurs when x = -b/2a

The projectile reaches the ground when the height is zero. The time when this occurs is the x-intercept of the zero of the function that is farthest to the right.​

Solve 8x + c = k for x
Natali [406]

Answer:

x = 1/8(k-c)

Step-by-step explanation:

8x + c = k

Subtract c from each side

8x +c-c = k-c

8x = k-c

Divide each side by 8

8x/8 = (k-c)/8

x = 1/8(k-c)
