The rock's height is increasing in the interval from 0 seconds to 3 seconds.

At time 0 the rock starts moving upward from 52 foot until it reachs 180 foot height (time 3 seconds). Then the rock starts to descend, which means that the height starts to decrease.

Answer from: natimike10

The interval as observed from the graph where the height of rock is increasing is (0,3).

Step-by-step explanation:

We are given the following in the question:

A rock is thrown from a 52 foot cliff.

The attached image shows the graph of height of rock y units in time x seconds.

Thus, the x-axis represents time in seconds.

The y-axis represents the height of the rock.

We have to find the interval for which the height of rock is always increasing.

Looking at the graph, the height of rock follows a parabolic pattern that is first the height of rock increases, reaches a maximum value and then decreases.

The interval as observed from the graph where the height of rock is increasing is (0,3).

This can be interpreted as:

From 0 to 3 seconds the height of the rock increases from 52 foot to 180 foot.At 3 second the rock is at maximum height that is 180 foot.After 3 seconds the height of the rock decreases from 180 foot to 0 foot that is ground level.

Answer from: Quest

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to $\frac{1}{60} hr\\$

then mult. both sides by 75 we get the ratio

75 mi. to $\frac{75}{60} hr\\$

simplifying we get

75 mi. to $\frac{5}{4} hr$

or 1.25 hr.
