We take the equation <span>d = -16t^2+12t</span> and subtract d from both sides to get
                                         0<span> = -16t^2+12t - d
We apply the quadratic formula to solve for t. With a = -16, b = 12, c = -d, we have
                                         t = [ -(12) </span><span>± √( 12^2 - 4(-16)(-d) ) ] / [2 * -16]</span>
                                           = [- 12 ± √(144-64d) ] / (-32)
                                           = [- 12 ± √16(9-4d)] / (-32)
                                           = [- 12 ± 4√(9-4d)] / (-32)
                                           = 3/8 ±√(9-4d) / 8
The answer to your question is t = 3/8 ±√(9-4d) / 8

Sides that match up between two similar figures are called corresponding sides.
Naily [24]

Answer:

A. Height of the Flag pole  

B. Longest.

Explanation:

Two similar triangles have corresponding sides with the same ratio.

A smaller triangle is showing the shadow of a person and the larger one is showing the shadow of a flag.

Now the person's shadow in the smaller triangle corresponding to the Height of the Flag pole.

The longest side of the large triangle corresponds with the Longest side of the smaller triangle.

Given: 3x &lt; -6.
ddd [48]

Answer: FIRST OPTION.

Step-by-step explanation:

To know which is the solution set given the inequality 3x < -6 you need to solve for the variable "x".

You must divide both sides by 3:

3x < -6\\\\\frac{3x}{3}=\frac{-6}{3}

Therefore, you get:

x

Then, the solution set is the following:

{x | x < -2}

You can observe that this solution set matches with the first option.
