Given: –c^{2}(3c – 2)
On opening the bracket, I get, = -3c^{3} + 2c^{2}

because , the following sign conventions are followed:
( - )× (-) = +

( - )× (+) = -
(+)× (-) = -
(+ )× (+) = +
thus the answer is -3c^{3} + 2c^{2}

ad-work [718]

>First jump = 4.25 m

 

>Best jump = 1.12 * First jump

Best jump = 1.12 * (4.25 m)

Best jump = 4.76 m

 

>Best jump = 0.85 * Winning jump

Hence,

Winning jump = Best jump / 0.85

Winning jump = 4.76 m / 0.85

The function h is defined as follows.
JulsSmile [24]

Answer:

The equation you are given is a quadratic. The standard form of a quadratic is y = a(x-h)2 + k where (h,k) is the vertex of the graph, which is a parabola. Vertically moving the graph 4 units upward means that you are moving k +4 units.

y = a(x-h)2 + k            standard form

y = 5x2 - 4                  original equation

y = 5(x-0)2 - 4            re-written in standard form

h = 0     k = -4

Four (4) units up is k + 4--->-4 + 4 = 0.

Therefore, f(x) = 5x2 + 0--->f(x) = 5x2.
