Janelle is using a piece of cardstock to create an open box with no top. The cardstock is 8 inches by 11 inches. She cuts a square with length out of each corner and folds up the sides to create the box. Find the volume of the box, , in standard form.

Answers

Answer: 4x^3-38x^2+88x

Step-by-step explanation:

The volume of the box in standard form is 4x³ - 38x² + 88x

Since Janelle cuts a square of side length x out of each corner of the cardstock, we have a length x + x = 2x cut out of each dimension of the cardstock.

Since the dimensions of the cardstock are 8 inches by 11 inches, cutting out a length of 2x inches from each dimension to produce the length, L and width, w of the open box, we have the length of the open box, L = 8 -2x and the width of the open box, W = 11 - 2x.

Since the height of the open box is the length x of the square cut out of each corner, and the open box is a rectangular box,

So, the volume of the box is

V = LWx

Substituting the values of the variables into the equation, we have

V = LWx

V = (8 - 2x)(11 - 2x)x

Expanding the brackets, we have

V = (88 - 16x - 22x + 4x²)x

V = (88 - 38x + 4x²)x

V = 88x - 38x² + 4x³

Re-arranging, we have

V = 4x³ - 38x² + 88x

So, the volume of the box in standard form is 4x³ - 38x² + 88x

Adding -5 is like subtracting 5

3 -5

-2

Answer:

-2

Step-by-step explanation:

You need to add a positive number and a negative number.

This is how you add a positive number and a negative number.

First, get rid of the signs and make them both positive.

Now you have 5 and 3.

Do a subtraction the way you first learned subtraction in elementary school, which is the larger number minus the smaller number.

5 - 3 = 2

The answer is either 2 or -2.

To finish the original addition, look at the two original numbers. 5 is greater than 3. 5, the greater value, is on a negative number, so the answer is negative.

3 + (-5) = -2

If the domain of the function f(x)=2x2- 8is {-2, 3, 5}, then the range is

Answers

Answer:

{0, 10, 42}

Step-by-step explanation:

Domain is set of input values and range is set output values.

For the function f(x) = 2x² - 8 and domain set of {-2, 3, 5}

Range is:

f(-2) = 2(-2)² - 8 = 0f(3) = 2*3² - 8 = 10f(5) = 2*5² - 8 = 42

Range: {0, 10, 42}

Write an equation in slope-intercept form of the line that is a segment bisector of both AB and CD. Ay 4 B(6,3) A(-4,1) -4 -2 2. 4 6 X D(5, -1) -2 4 C1-1,-5) -6​

Answers

Answer:

y = -5x + 7

Step-by-step explanation:

Given that the location of the points are:

A(-4, 1), B(6, 3), C(-1, -5) and D(5, -1)

The location of the bisector of a line is given as:

[tex]x=\frac{x_1+x_2}{2} \\\\y=\frac{y_1+y_2}{2}[/tex]

If E(x1, y1) is the bisector of segment AB then the location of E is at:

[tex]x_1 =\frac{-4+6}{2}=1 \\\\y_1=\frac{1+3}{2}=2[/tex]

Hence E is at (1, 2)

If F(x2, y2) is the bisector of segment CD then the location of F is at:

[tex]x_2 =\frac{-1+5}{2}=2 \\\\y_2=\frac{-5-1}{2}=-3[/tex]

Hence F is at (2, -3)

Hence the line that is a segment bisector of both AB and CD pass through the point (1, 2) and (2, -3).

The equation of the line is given by:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-2=\frac{-3-2}{2-1}(x-1)\\ \\y-2=-5(x-1)\\\\y-2=-5x+5\\\\y=-5x+7[/tex]

Answer: The equation is: y = -5x + 7.

Step-by-step explanation:

Given that the location of the points are:

A(-4, 1), B(6, 3), C(-1, -5) and D(5, -1).

Midpoint of A(-4, 1), B(6, 3) is = [tex]\left(\frac{\left(-4+6\right)}{2},\frac{\left(1+3\right)}{2}\right)=(1,2)[/tex].

Midpoint of C(-1, -5) and D(5, -1) is [tex]\left(\frac{\left(-1+5\right)}{2},\frac{\left(-5-1\right)}{2}\right)=(2,-3)[/tex].

Using point slope formula:

[tex]\frac{y-2}{x-1}=\frac{-3-2}{2-1}\\\frac{y-2}{x-1}=-5\\y-2=-5x+5\\y=-5x+7[/tex]

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that y = 2x and 3x – 3y = 2, therefore, if we substitute the value of y from y=2x into the second equation 3x-3y=2, then,

3x – 3y = 2

3x – 3(2x) = 2

3x – 6x = 2

–3x = 2

x = 2/–3

Hence, the value of x in the two of the given equations is 2/–3.

If ∠ABD and ∠CBD are a linear pair, m∠ABD = (3x+31)°, m∠CBD = (2x-6)°, then find m∠ABD. *

Answers

Answer:

∠ ABD = 124°

Step-by-step explanation:

A linear pair of angles sum to 180°, thus

∠ ABD + ∠ CBD = 180 , substitute values

3x + 31 + 2x - 6 = 180, that is

5x + 25 = 180 ( subtract 25 from both sides )

5x = 155 ( divide both sides by 5 )

x = 31

Thus

∠ ABD = 3x + 31 = 3(31) + 31 = 93 + 31 = 124°

Since we know that the area of the shaded sector is 10 pi, we can divide 10pi by 100pi to get 1/10. 1/10 is the area of the shaded sector compared to the area of the whole circle. Multiply 1/10 by the angle measure of a circle, which is 360, to get 36 degrees.
