Explanation:

a) The velocity curve is linearly increasing from 0 to 6 m/s over a period of 2 seconds, then linearly decreasing from 6 m/s to 0 over the same period. The acceleration is the rate of change of velocity, so for the first half of the motion the acceleration is a constant (6 m/s)/(2 s) = 3 m/s². Similarly, over the second half of the motion, the acceleration is a constant (-6 m/s)/(2 s) = -3 m/s².

The distance traveled is the integral of the velocity, so the linearly increasing velocity will cause the distance vs. time curve to have a parabolic shape. The shape will likewise be parabolic, but with decreasing slope, as the velocity ramps down to zero. Overall, the distance versus time curve will have an "S" shape.

The motion (position and velocity) will be continuous, but the acceleration will not be. There will be a significant "j.erk" at the 2-second mark where acceleration abruptly changes from increasing the velocity to braking (decreasing the velocity).

b) The attachment shows the (given) velocity curve in meters per second and its integral, the position curve, in meters.

The integral in the attached works nicely for machine evaluation. For hand evaluation, it is perhaps best written piecewise:

  s(t)=\begin{cases}\displaystyle\int_0^t{3x}\,dx\qquad\text{for $x\le2$}\n\n\displaystyle6+\int_2^t{(12-3x)}\,dx\qquad\text{for $2<x\le4$}\end{cases}

What is the answer to 3(2b-1)

Answers

You need to distribute the 3, so your answer would be 6b-3
You have to distribute the 3 to everything within the parenthesis.

3 • 2b = 6b & 3 • -1 = -3

So, your answer will be 6b-3.

Hope I helped. :)

Evaluate 8 − 12 ÷ 2 + 3. 1 −1 4 5

According to the order of operations, multiplication and division are performed before addition and subtraction.

... 8 - 12 ÷ 2 + 3

... = 8 - 6 + 3 . . . . . . 12÷2 = 6

... = 2 + 3 . . . . . . . . . 8-6 = 2

Step-by-step explanation:

Consider w1 = 4 + 2i and w2 = –1 – 3i. Which graph represents the sum w1 + w2?

Answers

Answer:

Option (2)

Step-by-step explanation:

Two points having real and imaginary parts are,

w₁ = 4 + 2i

w₂ = -1 - 3i

By adding these numbers,

w₁ + w₂ = (4 + 2i) + (-1 - 3i)

            = (4 - 1) + (2 - 3)i

            = 3 - (1)i

Since, coordinates of a number on the graph are (x, y)

Here x = Real part

y = Imaginary part

Therefore, sum of these numbers will be (3, -1).

Option (2) will be the correct graph.
