The distance of the hiker of a linear function.
The true statement is <em>(d) The y-intercept is (0, 2), and the 2 represents the number of miles from the car at the start of this time period.</em>
From the graph, we can see that the graph crosses the y-axis at: (0,2)
This means that, the y-intercept is (0,2), and 2 represents the number of miles, he started with.
Hence, the correct statement is (d)

You are solving for x, correct?
Answer:
dx/dt = 5√5/2
Step-by-step explanation:
Given:
dx/dt = 25 feet per second
According to Pythagoras theorem:
x² + 90² = y²
We know that x = 30 ft
So,
x² + 90² = y²
30² + 90² = y²
y = 30√10
So,
x² + 90² = y²
By taking differentiate:
2x dx/dt = 2y dy/dt
[x/y][dx/dt] = dy/dt
dx/dt = 5√5/2
You can find the perimeter by just counting the distance of every line segment all around the shape since they have vertical and horizontal slopes.
