Answer:
(a) The time to complete 1 cycle and return is 16/3
(b) The minimum height is 30 inches and the maximum is 54 inches
Step-by-step explanation:
Given
Solving (a): Time to complete 1 cycle and return
This implies that we calculate the period. This is calculated using:
Where:
So, we have:
Solving (b): The maximum and the minimum height
To do this, we have:
Which means:
So, the minimum is:
And the maximum is:
Recall that the height is:
So, the maximum and the minimum of are:
and
Answer:
60/30
Step-by-step explanation:
2 can be written as the rational number .
We want a denominator of 30, so we multiply the denominator by 30. However, we realize that if we only multiply the denominator by 30, we change the whole number from 2 into 2/30, which are obviously not the same. So, we have to multiply both the numerator and denominator by 30:
Thus, the answer is 60/30.
