Answer:
a) The mass is released at t = 0 when h is minimum. Half a cycle later h reaches its maximum and another half a cycle it reaches its minimum again. Hence over one cycle, h varies with t as follows:
b) According to the graph obtained in part a), h(t) could be modeled by a cosine function shifted (translated) vertically up and horizontally to the right. Hence
Step-by-step explanation:
Answer:
x ≤ 2
Step-by-step explanation:
We are given the inequality:
First, get rid of the denominator by multiplying both sides by 2:
Add both sides by 6 then subtract both sides by x:
Then divide both sides by 3:
Therefore, the answer is x ≤ 2
