"h and k cannot both equal zero" -- yes, it can. if the vertex of a parabola is at (0, 0), there's nothing incorrect/invalid about that!!
"k and c have the same value" -- k and c do not have the same value. "k" is the y-value of the vertex and c is the constant in your quadratic equation, and the constant is not necessarily the y-value.
"the value of a remains the same" -- this is true. the a's in your equations are the same values, because the a-value is the coefficient of the x-variable in both equations. y = a(x - h)^2 and y = ax^2 -- both of these have a applying to your x-variables.
"h is equal to one half -b" -- this isn't true. the formula for calculating the x value of the vertex (h is the x-value of the vertex) is h = (-b/2a). -b/2a is not the same as one half -b because this answer choice doesn't involve the a-value.
Answer:
put all of them which is a
Step-by-step explanation:
Answer:
8.8
Step-by-step explanation:
This is the correct answer because the 8 repeats.
The initial velocity is 19 ft/s.
This is in the form f(t) = -16t²+v₀t+h₀, where v₀ is the initial velocity. 19 is in the place of v₀, so it is the initial velocity.
Answer: 2.33, 1.87, 3.6, 7.1
Step-by-step explanation:
2.33, 1.87, 3.6, 7.1 is not arranged from smallest to the largest. Arranging the number will be 1.87, 2.33, 3.6, 7.1.
