Answer: undefined
Step-by-step explanation:
The answer is undefined because when you plug in the points in the formula
y2-y1/ x2-x1 the denominator is 0 which makes it undefined. Also when you put it into a graphing calculator it will say that its undefined.
Answer:
Chris will take 0.75 seconds to return to his starting height of 10 feet.
Step-by-step explanation:
Let the height of Chris be represented by
, where
is the height in feet and
, the time in seconds. First, we equalize the formula to a height of 10 feet and simplify the resulting expression, that is:


Then, we simplify the expression by algebraic means:

Roots of the polynomial are, respectively:

First root represents the initial height of Chris, whereas the second one represents the instant when Christ returns to the same height above the surface of the water. Hence, Chris will take 0.75 seconds to return to his starting height of 10 feet.
Answer:
41.67
Step-by-step explanation:
Using the tangent on the stick with shadow:
tan(θ) =
Using the tangent on the building:
tan(θ) = 
⇒ h = 25 · tan(θ)
= 25 ·
⇒ h = 41.66... ≈ 41.67
Answer:
I believe C, or the answer you have chosen, is correct.
Step-by-step explanation:
In this question, we add like, AKA similar, terms.
There is nothing to match x^2, so we leave it alone and put it at the head of equation since it has the highest power:
x^2
There is nothing to match -x, so we also leave it alone and put it next to x^2, keeping its sign:
x^2 - x
We can add 1 and 5 to get 6, so we put 6 next to the -x to get our final equation:
x^2 - x + 6.
