Please help me with this thank you so much
Tasya [4]

Answers:

<u>5) A.) 26</u> and <u>6) D.) 30</u>

Step-by-step explanations:

<em>Question 5)</em>

For this question, we need to analyze the graph given and look at how many people scored 601 or above on the math portion. So, looking at the answers given we aren't going to have a smaller number of only 16 or 10, since they are both equal to or higher than 601. So, we need to add the amount of students that scored the 601 or higher amount.

16 + 10 = 26.

This answer matches up with the answer given of A).

<em>Question 6)</em>

For this question, it is similar except you don't add the numbers given. Instead, the question is asking for a specific amount given. So, looking at the answers given, yes 18 and 6 did score below 500, but the question asked "...scored <u>500 or below</u>?" This is a specific question telling us about the 500 or below, which is in one column. As shown in the graph, 30 students scored this specific amount, which gives us our answer of D).

I hope that this helps.

astraxan [27]

Given:

The x- intercepts of a parabola are (0,-6) and (0,4).

The parabola crosses the y- axis at -120.

Lucas said that an equation for the parabola is y=5x^2+10x-120 and that the coordinates of the vertex are (-1, -125).

To find:

Whether Lucas is correct or not.

Solution:

The x- intercepts of a parabola are (0,-6) and (0,4). It means (x+6) and (x-4) are the factors of the equation of the parabola.

y=a(x+6)(x-4)             ...(i)

The parabola crosses the y- axis at -120. It means the equation of the parabola must be true for (0,-120).

-120=a(0+6)(0-4)

-120=a(6)(-4)

-120=-24a

Divide both sides by -24.

\dfrac{-120}{-24}=a

5=a

Substituting a=5 in (i), we get

y=5(x+6)(x-4)

y=5(x^2+6x-4x-24)

y=5(x^2+2x-24)

y=5x^2+10x-120

So, the equation of the parabola is y=5x^2+10x-120.

The vertex of a parabola f(x)=ax^2+bx+c is:

Vertex=\left(-\dfrac{b}{2a},f(-\dfrac{b}{2a})\right)

In the equation of the parabola, a=5,b=10,c=-120.

-\dfrac{b}{2a}=-\dfrac{10}{2(5)}

-\dfrac{b}{2a}=-\dfrac{10}{10}

-\dfrac{b}{2a}=-1

Putting x=-1 in the equation of the parabola, we get

y=5(-1)^2+10(-1)-120

y=5-10-120

y=-125

So, the vertex of the parabola is at point (-1,-125).

Therefore, Lucas is correct.
