A mountain is 12,408 feet above sea level, and a valley is 175 feet below sea level. What is the difference in elevation between
1 answer:
Answer:
The difference of <u>12,583 feet</u> in elevation between the mountain and the valley.
Step-by-step explanation:
Given:
A mountain is 12,408 feet above sea level, and a valley is 175 feet below sea level.
Now, to get the difference in elevation between the mountain and the valley.
As mountain is above sea level = 12,408 feet.
And valley is below sea level = 175 feet.
So, by adding we get the difference in elevation between the mountain and the valley:
Therefore, the difference of 12,583 feet in elevation between the mountain and the valley.

Option C) y + 4 = x
Step-by-step explanation:
We are given the following information in the question:
Line AB goes through the points A (0, –4) and B (6, 2).
We can use the two-point form of equation of straight line.
The equation of line is given by:
where, is the point through which the line passes.
The equation of line is:
Thus, the equation of line AB is given by Option C) y + 4 = x
Answer:
31). Maximum height = 100 feet
32). Time to hit the ground = 5 seconds
Step-by-step explanation:
31). Equation modeling the height 'h' of the ball is,
h = -16t² + 80t
For the maximum height of the ball,
Find the derivative of 'h' with respect to time 't' and equate it to zero.
seconds
That means after 2.5 seconds ball will reach the maximum height.
By substituting in the equation,
feet
Therefore, maximum height achieved by the ball is 100 feet.
32). If the ball follows the parabolic path,
Time taken by the ball to reach the maximum height = Time taken by the ball to come back to the ground from the maximum height.
Time taken by the ball to hit the ground = 2(2.5) = 5 seconds
