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.

See below
Step-by-step explanation:
If you are using a FAIR die the THEORETICAL probability of rolling a 5
would be 1 time out of 6
or 55 times out of 330
YOUR EXPERIMENTAL probability is 53 / 330
Answer: I believe it would be $12.50 . hope it helps!

Answer:
y = - 7x + 17
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 7x - 9 ← is in slope- intercept form
with slope m = - 7
Parallel lines have equal slopes, thus
y = - 7x + c ← is the partial equation
To find c substitute (1, 10) into the partial equation
10 = - 7 + c ⇒ c = 10 + 7 = 17
y = - 7x + 17 ← equation of parallel line
