Answer:
The velocity is - 5.5m/s
Explanation:
Given
[tex]x(t) = 2t^3 - 3t^2 - 4t[/tex]
Required
The velocity when acceleration = 0
First, calculate the velocity (v)
[tex]v = x'(t)[/tex]
[tex]x(t) = 2t^3 - 3t^2 - 4t[/tex] --- differentiate
[tex]x'(t) =6t^2 - 6t - 4[/tex]
So:
[tex]v(t) =6t^2 - 6t - 4[/tex]
Next, calculate acceleration (a)
[tex]a = v'(t)[/tex]
[tex]v(t) =6t^2 - 6t - 4[/tex] --- differentiate
[tex]v'(t) = 12t - 6[/tex]
So:
[tex]a(t) = 12t - 6[/tex]
From the question acceleration = 0
So:
[tex]a(t) = 12t - 6 =0[/tex]
[tex]12t - 6 =0[/tex]
Solve for t
[tex]12t = 6[/tex]
[tex]t = 6/12[/tex]
[tex]t=0.5[/tex]
Substitute [tex]t=0.5[/tex] in [tex]v(t) =6t^2 - 6t - 4[/tex] to get the velocity
[tex]v(0.5) = 6 * 0.5^2 - 6 * 0.5 - 4[/tex]
[tex]v(0.5) = -5.5[/tex]

Explanation:
this seems like the best answer

Answer:
1,800,000,000 ways
Explanation:
Given
[tex]Digits: 8[/tex]
[tex]Alphabets: 2[/tex]
Required
Number of ways of selection
From the 8 digits; the first must be nonzero (i.e. any of 1 - 9).
There are 9 ways of selecting this:
The other 7 digits could be any of the 10 digits and there may be repetition.
Each of the digits can be selected in 10 ways. So, the number of ways of selecting the 7 digits is: [tex]10^7[/tex]
For the alphabets:
The first can be selected from the [tex]5[/tex] letters while the second can be selected from the remaining [tex]4.[/tex]
So, the number of ways the alphabets can be selected is: [tex]5 * 4[/tex]
Total number of selection is:
[tex]Selection = First\ Nonzero* The\ 7\ other\ digits\ * The\ alphabets[/tex]
[tex]Selection = 9* 10^7 * 5 * 4[/tex]
