Answer:
$20.60
Step-by-step explanation:
25.75x20%=5.15
25.75-5.15=20.60
2.8
-14x+28=-4x
10x=28
X=2.8

The second derivative represents acceleration, so the larger the a value the faster the increase of velocity and accordingly a quicker progression towards positive or negative infinity.

Answer:
x(x − 6) (x + 5)
Step-by-step explanation:
this is the factored form of x^3 - x^2 - 30x
hope this helps and is right :)
Using the midpoint formula, the coordinates of Q are: <em>A. (-10, 1)</em>
<h3>What is the Midpoint Formula?</h3>
- Midpoint formula is given as,
Thus, given that:
- M is the midpoint of PQ.
- M (-4, 7)
- P (2, 13).
Therefore:
Solve for x-coordinate of P:
-4 = 1/2(2 + x1)
2(-4) = 2 + x1
-8 = 2 + x1
-8 - 2 = x1
x1 = -10
Solve for y-coordinate of P:
7 = 1/2(13 + y1)
14 = 13 + y1
y1 = 1
Therefore, using the midpoint formula, the coordinates of Q are: <em>A. (-10, 1)</em>
