A ball is thrown from a height of 65 meters with an initial downward velocity of 10/ms . The ball's height h (in meters) after t

seconds is given by the following. h=65-10t-5t^2 How long after the ball is thrown does it hit the ground? Round your answer(s) to the nearest hundredth. (If there is more than one answer, list them)

So you are asked to find t when the ball hits the ground, so set the equation to 0.
0=65-10t-5t^2

It's A.  All you have to remember here are your rules of translations.  If there is side to side movement within a parabola it will be indicated within a set of parenthesis with the x coordinate.  If there is no set of parenthesis with the x there is no side to side movement.  The quantity (x+3) ^{2} tells us that the vertex has moved left 3 units.

Which is the equation in the slope-intercept form of the line that contains points E &amp; F ?
sesenic [268]

Answer:

y = 4x - 12

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 )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = E(4, 4) and (x₂, y₂ ) = F(2, - 4)

m = \frac{-4-4}{2-4} = \frac{-8}{-2} = 4 , then

y = 4x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 4), then

4 = 16 + c ⇒ c = 4 - 16 = - 12

y = 4x - 12 ← equation of line
