Answer:

Hey!

Your answer would be 3,005.5!

Step-by-step explanation:

How did we get this?

Well to find the mean of a data set we...

ADD ALL THE VALUES UP and DIVIDE BY THE AMOUNT OF NUMBERS PRESENT...

So in this case...

WE DO: 3,004 + 3,007 = 6,011

NOW: DIVIDE BY 2...6,011 / 2

YOUR ANSWER IS 3005.5!

Hope this helps!

You measure a sheet of paper. The width is 8.47 inches and the length is 10.98 inches. What is the area of the paper in mks unit

Hoochie [10]

SOLUTION - GIVEN

Width = 8.47 inches

Length = 10.98 inches

FIND OUT - Area of a paper in mks units.

TO PROOF - Paper shape is like rectangle.

Formula

Area of a rectangle = length × breadth

= 10.98 × 8.47 $inches^2$

= 93.0006 $inches^2$

Now we require answer in mks units.

( mks units stand for the length in meter, mass in kilogram & time in

seconds.)

That means we require answer in meter unit.

1 inches = 0.0254 meter

Area of a paper = 93.0006 × 0.0254 × 0.0254 $meter^2$

= 0.0600002671 $meter^2$

Hence proved

If –3 i is a root of the polynomial function f(x), which of the following must also be a root of f(x)? –3 – i –3i 3 – i 3i

Ber [7]

If -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)

<h3>How to determine the true statement?</h3>

The root of the polynomial function is given as:

-3 + i

The above root is a complex root.

If a polynomial has a complex root, then the conjugate of the root is also a root of the function

The conjugate of -3 + i is -3 - i

Hence, if -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)

Determine the equation of the line that passes through the points of intersection of the graphs of the quadratic functions f(x)

timofeeve [1]

Answer: $x-2y-2=0$

Step-by-step explanation:

Given :

$f(x) = x^2 - 4 \\ g(x) = - 3x^2 + 2x + 8$

Point of intersection :

$f(x)=g(x)\\x^2-4=-3x^2+2x+8\\4x^2-2x-12=0\\2x^2-x-6=0\\2x^2-4x+3x-6=0\\2x(x-2)+3(x-2)=0\\(x-2)(2x+3)=0\\x=2\,,\,\frac{-3}{2}$

$x=2\,;f(2)=2^2-4=0\\x=\frac{-3}{2}\,; f\left ( \frac{3}{2} \right )=\left ( \frac{3}{2} \right )^2-4=\frac{-7}{4}=-1.75$

So, we have points $\left ( 2,0 \right )\,,\,\left ( -1.5,-1.75\ \right )$

Equation of line passing through two points $\left ( x_1,y_1 \right )\,,\,\left ( x_2,y_2 \right )$ is given by $y-y_1=\frac{y_2-y_1}{x_2-x_1}\left ( x-x_1 \right )$

Let $\left ( x_1,y_1 \right )=\left ( 2,0 \right )\,,\,\left ( x_2,y_2 \right )=\left ( -1.5,-1.75\ \right )$

So, equation is as follows :

$y-0=\frac{-1.75-0}{-1.5-2}\left ( x-2 \right )\\y=\frac{-1.75}{-3.5}\left ( x-2 \right )\\y=\frac{1}{2}(x-2)\\2y=x-2\\x-2y-2=0$
