Step-by-step explanation:
Let p be the number of trees Wangari plants, and h be the time she spends planting them in hours.
We have been given that Wangari plants trees at a constant rate of 12 trees every 3 hours.
Let us find number of trees planted in 1 hour by dividing 12 by 3.
We can represent this information as:
Therefore, the equation relates the number of trees (p) Wangari plants, and the time (h) she spends planting them in hours.
Answer:
Guillermo reach his lowest altitude 50 sec after diving and the lowest altitude is -125 m
Step-by-step explanation:
Let
x -----> the time in seconds
y ----> altitude in meters
we have
This is a vertical parabola open upward
The vertex is a minimum
To find out the lowest altitude, find the vertex
Complete the square
Factor the leading coefficient
Rewrite as perfect square
The vertex is the point (50,-125)
therefore
Guillermo reach his lowest altitude 50 sec after diving and the lowest altitude is -125 m (below the sea level)
