Answer:
Step-by-step explanation: Fourteen can be expressed as 2 + 3 + 4 + 5, also a sum of consecutive positive integers. Some numbers can be expressed as a sum of consecutive positive integers in more than one way. For example, 25 is 12 + 13 and is also 3 + 4 + 5 + 6 + 7.
<span>8 goes into 43 5 times with 3 left over so your answer will be = 5 3/8</span>
Answer:
Step-by-step explanation:
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
5(5a+b)-13
You would have to distribute
5*5a=25a
5*b=5b
