Answer:
A
Step-by-step explanation:
Let x = Tan
dx = sec²d
sqrt(1 + 
) = sec
So I = Tan(theta) * sec(theta)
but Tan(theta) = sin(theta) / cos(theta) = sin(theta)*sec(theta)
So I = integral sin(theta)*sec^2(theta) d theta
Answer A
Answer:
(-1,0)
Step-by-step explanation:
Given that ;
1 minute= 1 revolution
2minutes=2 revolution
30seconds, 0.5 minutes= 1/2 a revolution
Hence;
2 minutes 30 seconds will be two and a half revolutions
2 minutes will complete 2 revolutions to return to point (1,0), then from (1,0), the carousel proceeds to cover the half revolution and complete 2 minutes and 30 seconds
Note the revolutions will be conducted in anticlockwise direction, so the 1/2 revolution will follow the property of rotation in anticlockwise direction about the origin through 180°, starting from point (1,0)
The property states that a points (h,k) rotated about the origin in anticlockwise direction through 180° will be mapped to (-h,-k)
Hence (1,0) will be mapped to (-1,0)
Answer:
4/5
Step-by-step explanation:
slope = (difference in y)/(difference in x)
slope = (-5 - 3)/(-5 - 5)
slope = -8/(-10)
slope = 4/5
