Answer:

If the units in the equation are in feet, it lef5t at a height of 7.4 feet (or meters, etc.).

Step-by-step explanation:

p(x) = - 0.013x2 + 0.02x + 7.4

When x, the time, = 0 [just before it leaves the pitcher's hand]

p(0) = 7.4

Angle ABD and Angle CBD are supplementary angles and Angle CBD and Angle DBE are complementary. If the measure of angle ABD is 1
gizmo_the_mogwai [7]

Answer:

54°

Step-by-step explanation:

ABD = 144°

ABD + CBD = 180°......(i)

CBD + DBE = 90°........(ii)

From (i)

144° + CBD = 180°

CBD = 180° - 144°

= 36°

From (ii)

CBD + DBE = 90°

36° + DBE = 90°

DBE = 90 - 36

= 54°

Factor completely and then place the factor. in the proper location on the grid (4x-+3)(-2x-5)
Ivahew [28]
Yay, love these ones.

First of all, (4x-+3)(-2x-5) is the same as (4x-3)(-2x-5)
So the method for solving these can be remembered by FOIL.
F= Firsts   O= Outsides   I= Insides   L= Lasts

In other words everything is multiplied by everything, for example:
4x * -2x and -3 * -5 <span>is the firsts of the brackets multiplied and last of the brackets mulitplied
</span>
4x * -5 and 3 * -2x is the outsides of the brackets multiplied and the insides of the brackets multiplied
<span>
The SUM of FOIL is then added:</span><span>
</span><em>4x*-2x = -8x^2</em>
<em>-3*-5= 15</em>
<em>4x*-5=-20x</em>
<span><em>3*-2x=-6x</em>
</span><span>-8x^2 -20x -6x + 15 = 0
-8x^2 -26x + 15 = 0

So the factored of (4x-3)(-2x-5) <u /><em>=</em> -8x^2 -26x + 15 = 0

So then you graph that equation on your given grid
