Think through this one...

9:48 + 9 minutes = 9:57

9:57 + 30 minutes = 10:27

10:27 + 3 hours = 1:27 p.m.

which statements are true about the graph of the function f(x) = 6x – 4 x2? check all that apply. the vertex form of the functio
Brut [27]

Answer:

The vertex of the function is the point (-3,-13)

The graph increase over the interval--------> (-3,∞)

Step-by-step explanation:

we have

f(x)=6x-4+x^{2}

<u>1) Convert to vertex form</u>

Group terms that contain the same variable, and move the constant to the opposite side of the equation

f(x)+4=x^{2}+6x

Complete the square. Remember to balance the equation by adding the same constants to each side

f(x)+4+9=x^{2}+6x+9

f(x)+13=x^{2}+6x+9

Rewrite as perfect squares

f(x)+13=(x+3)^{2}

f(x)=(x+3)^{2}-13 -----> function in vertex form

<u>2) Find the vertex</u>

The vertex of the function is the point (-3,-13)

<u>3) Find the axis of symmetry</u>

we know that

In a vertical parabola, the axis of symmetry is equal to the x-coordinate of the vertex

The x-coordinate of the vertex in this problem is equal to x=-3

therefore

the equation of the axis of symmetry is  x=-3

<u>4) Find the increase-decrease intervals</u>

The graph increase over the interval--------> (-3,∞)

The graph decrease over the interval--------> (-∞,-3)

see the attached figure to better understand the problem

<u>5) Find the x-intercepts of the function</u>

we know that

the x-intercepts are the values of x when the value of the function is equal to zero

In this problem the x-intercepts are  

(-6.61,0) and (0.61,0)

so

The function cross the x-axis twice

see the attached figure

The discriminant of a quadratic equation is 40. What is the nature of solutions?
RSB [31]

Answer:

It means that the roots of the quadratic equation are real and distinct

Step-by-step explanation:

Here, given the discriminant of the quadratic equation, we want to find out the nature of the solutions.

Mathematically, we can use to determine the nature of the discriminant.

By it’s formula;

D = b^2 - 4ac

We can see that the given discriminant 40 is a positive value. What this means is that the quadratic equation has roots which are real and are distinct

A softball is tossed into the air upward from a first floor balcony. The distance of the ball 14 +32t -16t^2 above the ground at
snow_tiger [21]
You can either find the roots of the quadratic formula using the quadratic formula two find the halfway point or you can use the formula t=-b/2a.  Both of the two methods gives you the axis of symmetry (the t value for the vertex).
I will use the second method since I don't like using the quadratic formula.
t=-32/(2x-16)
t=1 second
After you find the t value for the axis of symmetry, you plug it into the formula of the graph to find the height.
h=-16+32+14
h=30 feet
