The height h, in feet, of a ball that is released 4 feet above the ground with an initial velocity of 80 feet per second is a fu

gulaghasi [49]

Answer with Step-by-step explanation:

The height of the ball from the ground as a function of time is given by

$h(t)=-16t^2+80t+4$

The height of the ball at any instant of time can be found by putting the value of time 't' in the above relation as

Part a)

Height of ball after 2 seconds it is released is

$h(2)=-16\times 2^2+80\times 2+4=100feet$

Part b)

Height of ball after 4 seconds it is released is

$h(4)=-16\times 4^2+80\times 4+4=68feet$

What is the factored form of the expression?

Georgia [21]

Answer: The answer is (d) $(4x+7)(7x+8).$

Step-by-step explanation: Given equation to be factored is

$28x^2+81x+56.$

The given expression is quadratic, so we can factor it into two linear factors, by using the following factorisation rule.

$x^2+(a+b)x+ab=(x+a)(x+b).$

So, the given equation can be factorised using the above rule. The factorisation is as follows.

$28x^2+81x+56\\\\=28x^2+49x+32x+56\\\\=7x(4x+7)+8(4x+7)\\\\=(4x+7)(7x+8).$

Thus, the correct option is (d).
