x represents the horizontal distance, which statements are true? Check all that apply
The scenario can be represented by the function h(x)=-0256)(x-5).
The scenario can be represented by the function h(x)= 16)(x + 5).
The vertex is on the line x=25.
The greatest height that the water reaches is 15 units.
The scenario can be represented by the function h(x)=-166-5).
Answer:
Step-by-step explanation:
From the problem, we deduct that the function has to be quadratic, because it's mention two zeros, which is proper of a polynomial expression with grade 2.
So, we can say that:
Because, 5 and 0 are roots of the expression.
Also, we know that the point is on the curve, this means:
Replacing this relation in the first expression, we have:
So, the expression would be:
If we graph, we could get the vertex easier.
You can see in the image, that the vertex is at x = 2.5
Therefore, the option C is the answer.
However, the first option has this function:
h(x) = –0.25(x)(x – 5).
Which also can be solution, because, if we try x = 4:
h(4) = –0.25(4)(4 – 5)=1
Therefore, option A is also part of the answer.
Answer
answer A and C are right
S (-5k +20)
13
Answer:
- 10
Step-by-step explanation:
Substitute k = 3, 4, 5, 6 into the expression and sum the terms, that is
(- 15 + 20) + (- 20 + 20) + (- 25 + 20) + (- 30 + 20)
= 5 + 0 - 5 - 10
= - 10
