I'd guess the slope is 1.3 but I'm not sure
Answer:-5
Step-by-step explanation:
Answer: For Part A, there are 9,604 possibilities. For Part B, there are 1,440 possibilities.
To find the total number of possibilities, we will use the Fundamental Counting Principle. To do this, we find the number of possibilities for each position and then multiply them.
For Part B:
There are only 4 possibilities for the first position, since it must be odd (1, 3, 5, 7). The for the next 4 digits, all 7 numbers are a possibility.
4 x 7 x 7 x 7 x 7 = 9604
For Part B:
We again start with 4, however the numbers can be repeated. So we reduced the number of choice by 1 each time.
4 x 6 x 5 x 4 x 3 = 1440
As the comments state, the velocity is the derivative of the position.
Therefore, the velocity as function of time is:
ds / dt = 24 + 6t - 3t^2.
That is a parabola whose maximum is (1,27). With that you know that the velocity will never be either 63 m/s or 81 m/s.
Also, you know that the velocity at t = 1 s is 27 m/s.
And, you can also find that the velocity at t = 3 is 15 m/s.
I am confident on that this analysis solves your question. Else, insert a comment.
