Explain why the result is always the original number followed by your age

It isn't.  For example, if I integrate the function [ 2sin(θ) + 3cos(θ) ] between
the limits of -π and +π, my age does not appear anywhere in the result.

It depends on how the calculation is set up, and what steps you go through
to get the result.  You haven't told us anything about that.

Graph the function represented in the table on the coordinate plane.
Umnica [9.8K]
First find out the function for the given table.
Find the slope.
m= (y2-y1)/(x2-x1)
m=(-1-(-3)) / (-1-(-2))
m=(-1+3) / (-1+2)
m=2/1
m=2
Now equation of line:
y-y1=m(x-x1)
y-(-3)=2(x-(-2))
y+3=2(x+2)
y+3=2x+4
y=2x+1
Now plot these points on the graph, we get the attached graph.

ahrayia [7]
y= -\frac{1}{2} x^{2}-1 is a quadratic function, so its graph is a parabola.

Notice that the coefficient of x is 0, this always means that the axis of symmetry is the y-axis.

That is, the vertex of the parabola is in the y-axis, so the x-coordinate of the vertex is 0.

for x=0, y=-1. So the vertex is (0, -1)

The coefficient of x^{2} is negative. This means that the parabola opens downwards, so the vertex is a maximum.


Answer: (0, -1) , maximum (none of the choices)

Create a factorable polynomial with a GCF of 2. Rewrite that polynomial in two other equivalent forms. Explain how each form was
earnstyle [38]
 4x^2 + 8x + 12

Equivalent forms: x^2 + 2x + 3 and 8x^2 + 16x + 24.

The first equivalent form was created by dividing each term by 2, and the second equivalent form was created by multiplying each term by 2.

Solve x ^ 2 - 3x = - 8 using the quadratic formula.
Sergio039 [100]

Answer: \frac{3 +- \sqrt{23}i}{2} If using complex numbers, or undefined if using all real numbers

Step-by-step explanation:

Moving -8 to the left side of the eq by adding both sides by 8=

x^2-3x+8=0

The quad formula:\frac{-b  +- \sqrt{b^2-4ac}}{2a}

a=1 b=-3 c=8

Inserting a b c values into formula: \frac{-(-3)  +- \sqrt{(-3)^2-4(1)(8)}}{2(1)}

Simplifying: \frac{3 +- \sqrt{9-32}}{2}

\frac{3 +- \sqrt{-23}}{2}  Since the square root of a negative number doesn't exist in the set of real numbers, the equation is undefined.

OR

\frac{3 +- \sqrt{23}i}{2} Using complex numbers i, to replace the negative number created by subtracting 9-32.
