Answer:
Below in bold.
Step-by-step explanation:
A. −16x2 + 24x + 16 = 0
-8(2x2 - 3x - 2) = 0
-8(2x + 1 )(x - 2) = 0
x = -0.5, 2.
So the x-intercepts are (-0/5, 0) and (2, 0).
B. As the leading coefficients is negative (-16) the vertex of the graph will be a Maximum.
To find its coordinates we convert the function to vertex form:
f(x) = −16x2 + 24x + 16
= -16(x^2 - 1.5x) + 16
Completing the square on contents of the parentheses:
= -16 [(x - 0.75)^2 - 0.75^2] + 16
= -16(x - 0.75)^2 - 16 * -0.75^2 + 16
= -16(x - 0.75)^2 + 9 + 16
= -16(x - 0.75)^2 + 25.
So the coordinates of the vertex are (0.75, 25)
The time × 1.5=the distance
so 5×1.5=7.5
10×1.5=15
20×1.5=30

Answer:
P = - 7
Step-by-step explanation:
To solve we must put all the literals (letters) on one side of the operation and all the free numbers on the other. To do this we are going to do the same operations on both sides of the equal sign
- 15 - 3p = 6
So, we are going to add 15 on both sides
- 15 - 3p + 15 = 6 + 15
- 3p = 21
We are goint to divide everything by -3
-3p/-3 = 21/-3
It result:
<h2>p = -7</h2><h2 />
We check as follows:
We are going to replace the unknown (p) by the value we gave it already (-7)
-15 - 3(-7) = 6
-3 × -7 = +21
-15 + 21 = 6
6 = 6
we have the correct result
