Answer:
positive 3
Step-by-step explanation:
-8 + 11 is 3. the other way you can think of it is by subtracting 8 from 11.

Step-by-step explanation:
<u>Step 1: Define</u>
-84 = -2(2 + 5k)
<u>Step 2: Solve for </u><em><u>k</u></em>
- Divide -2 on both sides: 42 = 2 + 5k
- Isolate <em>k</em> term: 40 = 5k
- Isolate <em>k</em>: 8 = k
- Rewrite: k = 8
<u>Step 3: Check</u>
<em>Plug in k into the original equation to verify it's a solution.</em>
- Substitute in <em>k</em>: -84 = -2(2 + 5(8))
- Multiply: -84 = -2(2 + 40)
- Add: -84 = -2(42)
- Multiply: -84 = -84
Here we see that -84 does indeed equal -84.
∴ k = 8 is the solution to the equation.
Answer:
Since acceleration is the derivative of velocity, velocity is the antiderivative of acceleration. If you know the acceleration for all time, and if you know the starting velocity, you can figure out the velocity for all time.

Answer:
A and B
Step-by-step explanation:
The minimum occurs at the turning point ( vertex )
The coordinates of the vertex are (1, - 2 ) → A
The x- intercepts are the points where the graph crosses the x- axis
This occurs at (3, 0 ) and (- 1, 0 ) → B
The axis of symmetry is a vertical line passing through the vertex
Equation of axis of symmetry is x = 1 , not y = - 2
(1, - 2 ) is a minimum not a maximum , see above
