Answer:

  D.  The ball was thrown from an initial height of 3 feet.

Step-by-step explanation:

The generic form of the equation for (vertical) ballistic motion is ...

  h(t)=-\dfrac{1}{2}gt^2+v_0t+h_0

where g is the acceleration due to gravity, usually approximated as 32 ft/s², v₀ is the initial upward velocity, and h₀ is the initial height.

The given equation matches the situation where the object was launched vertically at the rate of 40 ft/s from a height of 3 ft.

The 3 represents an initial height of 3 feet.

Factor this trinomial completely.
WITCHER [35]

Answer:

Option C. (2x+3)(6x – 5) is the correct answer.

Step-by-step explanation:

Given polynomial(trinomial) is:

12x^2 + 8x - 15

The given trinomial is quadratic. Factorization will be as follows:

Multiplying the co-efficient of x^2 and the constant results in 180. We have to make factors of 180 in such a way that their sum of difference is equal to the co-efficient of x.

The required factors are 18 and 10

So,

=12x^2+18x-10x-15\\=6x(2x+3)-5(2x+3)\\= (6x-5)(2x+3)

Hence,

Option C. (2x+3)(6x – 5) is the correct answer.
