<span>The equation is e = 300 - 10t. t is greater or equal than 0 and given that e cannot be negative, 300 - 10 t greaetr or equal than 0 => 10 t greater or equal than 300, and t greater or equal than 300/10 = 30. This is the viable points are times from 0 to 10 and elevation from 300 to 0. Some points are (0,300) which is the initial point (when Rory is on the top); (1, 290); (2, 280); (3, 270); (4, 260); (5, 250); (6, 240); (10, 200), (20, 100), (30, 0).</span>
Answer:
(5, -3)
Step-by-step explanation:
given two points (x₁, y₁) and (x₂, y₂), the midpoint is 
= 
Answer:
No
Step-by-step explanation:
A relation is a function if every x-value has exactly one y-value.
Because the x-value 1 has two y-values (-3 and 3), the relation is not a function.
Plotting (1, -3) and (1, 3) will produce a vertical line that intersects the function at two points.
Therefore, the relation is not a function.
Hope that helps.
Answer:
The given function 
was replaced with 
then the value of k is -3
that is k=-3.
Step-by-step explanation:
The given function is 
and when x=x+k then 
Now to find the value of k:
Put x=x+k in the function f(x)
Now comparing equations (2) and (3) we get
Therefore k=-3
Therefore the given function was replaced with then the value of k is -3
that is k=-3.
