"<" is definitely "less than". It denotes the inequality between two values.

Explain how you could write a quadratic function in factored form that would have a vertex with an x-coordinate of 3 and two dis

skad [1K]

The definition of quadratic function is given by:

 $(1) \ f(x)=ax^{2}+bx+c \\ \\ where \ a, b, c \ are \ real \ values$ 

So the problem asks for two conditions:

1. Write the quadratic function in factored form. 
2. The vertex has an x-coordinate of 3.

Then the equation (1) must be written as follows:

 $f(x)=(x-m)(x-n) \\ \\ where \ m \ and \ n \ are \ the \ roots$ 

To satisfy the two conditions:

$\frac{m+n}{2}=3$

So we are free to choose the value of one root, say:

$m=1$

Thus:

$n=6-1=5$

Finally, the answer is:

$f(x)=(x-1)(x-5)$

The graph of this function is shown in the figure below.

What are the coordinates of the red dot?

kow [346]

Answer:

(5, 2)

Step-by-step explanation:

Coordinates of a point in a coordinate plane is usually written as (x, y). This point contains the value of x and its corresponding y value.

The red dot on the plane given, if you trace it down to the x-axis, it is at x = 5, while if you trace it horizontally against the y-axis, you'd have y = 2.

Therefore, the coordinates of the red dot is (5, 2).

Find an equation in standard form for the hyperbola with vertices at (0, ±2) and foci at (0, ±7).

Alisiya [41]

Standard Form of an Equation of an Hyperbola opening up and down is:

(y-k)^2 / b^2 - (x-h)^2 / a^2 = 1

where Pt(h,k) is a center with vertices 'b' units up and down from center.

vertices: vertices: (0,+-2) b = 2 AND Center is (0,-0)

(y)^2/4-(x)^2/a^2=1

foci: (0,+-7)

a^2 = 24

square root of 4 + a^2 = 5.29

4 + 5.29 = 9.29

y^2 / 4 - x^2 / 24 = 1
