B
Step-by-step explanation:
5 x 6 x 5
30 x 5
150
Answer:
0.75
Step-by-step explanation:
Each 1/4 is a quarter so multiply 0.25*3 which equals 0.75
X(t) = 1/2sin t + cos (2t)
speed = x'(t) = 1/2cos t - 2sin(2t)
acceleration = x''(t) = -1/2sin t - 4cos(2t)
When t = pi/2,
acceleration = -1/2sin(pi/2) - 4cos(pi) = -1/2 - 4(-1) = -1/2 + 4 = 3 1/2 = 7/2 m/s^2
Answer:
Step-by-step explanation:
Adding equation 1 and 2 we have
-x=27
Therefore x= -27
Substituting the value of x into equation 2 we have
-108+y = 6
y = 114
