Answer:
s = 6 m
Step-by-step explanation:
The value of the velocity v is given as:
m/s
To find s, we have to integrate and apply the initial values of s = o when t = 0:

When t = π/2, s will be:
s = -3cos(2 * π/2) + 3
s = -3cos(π) + 3
s = -3(-1) + 3
s = 3 + 3
s = 6 m
We're looking for a percentage of the people who voted for Candidate-A. So
the first thing we need to know is: How many people voted for Candidate-A ?
The number of people who voted for Candidate-A is
(1,253 men) + (1,921 women) = 3,174 people .
The question is: What percent of those people were women ?
Out of the total, 1,921 were women.
To find percent, you divide the part by the total.
1,921 / 3,174 = 0.6052 .
Changed to percent and rounded to the nearest whole one, that's<em> 61% .</em>
The answer is the option D.
You have to use implicit derivative
1) dy / dx = y'
2)
I think the answers are A and C. Hope this helps ☺
