The equation for percentage increase is
{(New value - old value) / old value} x100%
Therefore it should be
{(22.5 - 19.5) / 19.5} x 100%
=15% (rounded to nearest whole number)
Answer is B

Which statement is true about the flight of 2 rockets?
umka21 [38]

Answer:

  The first rocket, g(x), reached its maximum height before the second rocket, h(x).

Step-by-step explanation:

Each equation is in vertex form, so we can read the vertex of the rocket's path from the equation.

  y = a(x -h)^2 +k . . . . . . has vertex (h, k)

__

g(x) has vertex (time, max height) = (4, 170).

h(x) has vertex (time, max height) = (5, 170).

The rockets have the same maximum height (170), but the first rocket, g(x), reaches that height in 4 seconds, one second sooner than the second rocket, h(x).

The first rocket, g(x), reached its maximum height before the second rocket, h(x).

The vertex of the graph of y = -4(x + 3)2 + 2 is ( , )
andrezito [222]

Answer:

Step-by-step explanation:

This quadratic is of the form

y=-a(x-h)^2+k where h and k are the coordinates of the vertex. Notice that inside the parenthesis it very specifically follows the format (<u>x -</u> h)². That means that if you have something like what we have here, ( x + 3)^2, it was originally (x - (-3))^2, and the value for h is -3. k is much simpler to determine. Our 2 at the end is a +2, so the k is 2. The vertex then is (-3, 2).
