Step-by-step explanation:

Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.

Answer:

  D(-7, 2)

Step-by-step explanation:

The midpoint of diagonal AC is the same as the midpoint of diagonal BD, so ...

  (A+C)/2 = (B+D)/2

We can solve for D by multiplying by 2 and subtracting B:

  D = A + C - B

  D = (-2, 4) +(-4, 1) -(1, 3) = (-2-4-1, 4+1-3)

  D = (-7, 2)

Answer:

x=56.7

Step-by-step explanation:

From the given triangle, the opposite side of angle x is 66 mm

79 mm is opposite to the right angle, so hypotenuse = 79 mm

we know the opposite side and the hypotenuse

To find the angle we use sin

[tex]sin(x)= \frac{opposite side}{hypotenuse}[/tex]

opposite side = 66

hypotenuse = 79

[tex]sin(x)= \frac{66}{79}[/tex]

[tex]x=sin^{-1}(\frac{66}{79})[/tex]

x=56.66199855

Round the answer to nearest tenth

x=56.7

Step-by-step explanation & answer:

Let

x = "one number", then

4x+2 = "the other number"

If the sum is decreased by two, that gives

sum decreased by two = (x+4x+2) - 2 = 5x

The sum decreased by two = 25 (given)

therefore

5x = 25

x = 5

Answer:

  C)  65,535

Step-by-step explanation:

You can add up the 8 terms ...

  3, 12, 48, 192, 768, 3072, 12288, 49152

to find their sum is 65535.

_____

Estimating

Knowing the last term (49152) allows you to make the correct choice, since the sum will be more than that and less than double that.

_____

Using the formula

You know the formula for the sum of a geometric sequence is ...

  S = a1(r^n -1)/(r -1)

where a1 is the first term (3), r is the common ratio (4), and n is the number of terms (8).

Filling in the values, you find the sum is ...

  S = 3(4^8 -1)/(4-1) = 4^8 -1 = 65535

The sum of the geometric sequence 3, 12, 48, ... with 8 terms is 65,535. We use the geometric sum formula and identify a common ratio of 4 to compute the answer, which is option C.

To find the sum of a geometric sequence, we use the formula S = a * (1 - r^n) / (1 - r), where S is the sum of the sequence, a is the first term, r is the common ratio, and n is the number of terms. In this sequence, the first term a is 3, and we can find the common ratio r by dividing the second term by the first term: r = 12 / 3 = 4. With 8 terms in the sequence, we can calculate the sum.

S = 3 * (1 - 4^8) / (1 - 4) = 3 * (1 - 65536) / (1 - 4) = 3 * (-65535) / (-3) = 65535.

Therefore, the sum of the sequence is 65,535, which corresponds to option C.

Answer:

Step-by-step explanation:

The volume for a cube is V = l × w × h

But since this is a cube, all the sides aree the same length, so we could rewrite this in terms of x as:

V = [tex]x^3[/tex]

If we know the volume to be 1000, we sub it in for V:

[tex]1000=x^3[/tex]

We "undo" a cube by taking the cubed root of both sides.  The cubd root of x cubed is just x, and the cubed root of 1000 is 10.  Therefore, x = 10

Answer:

B.  z = 2

Step-by-step explanation:

Set up the matrix like this.  I multiplied the last row by a 2 to get rid of the fractions so that's what you will see:

[tex]\left[\begin{array}{ccc}2&1&-1\\0&2&3\\-1&2&2\end{array}\right][/tex]

I used Cramer's Rule to solve for the value of y.  In order to do that you need to find the determinant of the matrix, then you need to find the determinant of the matrix after you sub the solution set into the column representing z.

Find the determinant requires that I "pick up" the first 2 columns and then drop them at the end of the matrix and do the multiplication of the majors minus the minors.  The matrix looks like this:

2    1    -1    2    1

0    2    3    0    2

-1    2    2    -1    2

The multiplication of the majors:

[(2×2×2)+(1×3×-1)+(-1×0×2)] = (8-3+0)=5

The multiplication of the minors:

[(-1×2×-1)+(2×3×2)+(2×0×1)] = (2+12+0) = 14

So the determinant of the matrix is I A I = 5 - 14 = -9

Now for the determinant of z, noted as I [tex]A_{z}[/tex] I.  Notice that I am replacing the laast column with the solution set this time:

2    1    -8    2    1

0    2    -6    0    2

-1    2    -8    -1    2

The multiplication of the majors:

[(2×2×-8)+(1×-6×-1)+(-8×0×2)] = (-32+6+0) = -26

The multiplication of the minors:

[(-1×2×-8)+(2×-6×2)+(-8×0×1)] = (16 - 24 + 0) = -8

So the determinant of I [tex]A_{z}[/tex] I = -18

Cramer's Rule is to divide I [tex]A_{z}[/tex] I by I A I:

[tex]\frac{-18}{-9}= 2[/tex]

So the value you need for z to solve for y is 2

The value of z is 2.

The correct answer is an option (B) z = 2

"It is a set of numbers arranged in rows and columns so as to form a rectangular array."

"An inverse of matrix 'B' is  a matrix such that [tex]B\times B'=I[/tex] where [tex]I[/tex] is an identity matrix."

"It is a set of equations for which we find a common solution."

For given question,

We have been given a system of equations.

2x + y - z = -8

2y + 3z = -6

-1/2x + y + z = -4

We can write the third equation as, -x + 2y + 2z = -8

So, we have system of equations,

2x + y - z = -8

2y + 3z = -6

-x + 2y + 2z = -8

We write above system of equations in matrix form as,

[tex]\Rightarrow \begin{bmatrix}2 & 1 & -1 \\0 & 2 & 3 \\-1 & 2 & 2\end{bmatrix}[/tex] [tex]\begin{bmatrix}x \\y \\z\end{bmatrix}[/tex] [tex]=\begin{bmatrix}-8 \\-6 \\-8\end{bmatrix}[/tex]

⇒ AX = B

We use inverse matrix to find the solution of given system of equations.

Pre-multiply both the sides of above equation by [tex]A^{-1}[/tex]

[tex]\Rightarrow A^{-1} AX = A^{-1}B\\\\\Rightarrow IX=A^{-1}B\\\\\Rightarrow X=A^{-1}B[/tex]

The inverse of matrix A is,

[tex]A^{-1}=\begin{bmatrix}\frac{2}{9} & \frac{4}{9} & \frac{-5}{9} \\\\\frac{1}{3} & \frac{-1}{3} & \frac{2}{3} \\\\\frac{-2}{9} & \frac{5}{9} & \frac{-4}{9}\end{bmatrix}[/tex]

[tex]\Rightarrow \begin{bmatrix}x \\y \\z\end{bmatrix}=\begin{bmatrix}\frac{2}{9} & \frac{4}{9} & \frac{-5}{9} \\\\\frac{1}{3} & \frac{-1}{3} & \frac{2}{3} \\\\\frac{-2}{9} & \frac{5}{9} & \frac{-4}{9}\end{bmatrix} . \begin{bmatrix}-8 \\-6 \\-8\end{bmatrix}[/tex]

[tex]\Rightarrow \begin{bmatrix}x \\y \\z\end{bmatrix}= \begin{bmatrix}0 \\-6 \\2\end{bmatrix}[/tex]

To find the closing price of the stock, we need to add the increase to the opening price:

Convert the mixed numbers to improper fractions: [tex]\$33\frac{1}{8} = \frac{265}{8} \ and\ \$4\frac{1}{4} = \frac{17}{4}[/tex]

Find a common denominator to add the fractions: Since 8 and 4 are both multiples of 4, we will convert [tex]\frac{17}{4} to \frac{34}{8}.[/tex]

Add the fractions [tex]: \frac{265}{8} + \frac{34}{8} = \frac{299}{8}[/tex]

Convert the improper fraction back to a mixed number: [tex]\frac{299}{8} = $37\frac{3}{8}[/tex]

Therefore, the closing price of the stock was  [tex]$37\frac{3}{8}[/tex]per share.

Answer:

  A. 17 1/2 . . . cubic feet

Step-by-step explanation:

The volume is the product of the length, width, and height. If your calculator doesn't deal with mixed numbers, it can be convenient to use one that does.

  (4 ft)(2 1/2 ft)(1 3/4 ft) = 17 1/2 ft³

The volume of the box is 17 1/2 cubic feet.

____

You can also convert the numbers to decimal to use on your calculator:

  4 × 2.5 × 1.75 = 17.500

Or convert them to improper fractions:

  4 × 5/2 × 7/4 = 35/2 = 17 1/2

Final answer:

The volume of the box is 17 1/2 cubic feet, making the correct answer A. 17 1/2.

Explanation:

To find the volume of the box, we need to multiply its length, width, and height together.

The formula for volume is Volume = length × width × height.

Given that the box has a length of 4 feet, a width of 2 1/2 feet, and a height of 1 3/4 feet, we first need to convert these measurements into improper fractions or decimals to make the multiplication easier.

Width: 2 1/2 feet = 5/2 feet
Height: 1 3/4 feet = 7/4 feet

Volume = 4 feet × (5/2 feet) × (7/4 feet) = 20/2 × 7/4 = 10 × 7/4 = 70/4 = 17 1/2 cubic feet.

Therefore, the correct answer is A. 17 1/2 cubic feet.

x = 1

y = 6(1) - 4 = 2

Check:  y = 5(1) - 3 = 2, good

Answer: (1, 2)

Final answer:

To solve the given system of linear equations, we use substitution to find y = 1/9 and then find x = 7/9 as the values that satisfy both equations.

Explanation:

The student is attempting to solve a system of linear equations. To find the values of x and y that satisfy this system, we need to use a method such as substitution or elimination. Given the system:

x = −2y + 1

13x + 8y = 11

We can substitute the expression for x from the first equation into the second equation:

13(−2y + 1) + 8y = 11

−26y + 13 + 8y = 11

−18y + 13 = 11

−18y = −2

y = −2/−18

y = 1/9

Now we can substitute this value of y back into the first equation to find x:

x = −2(1/9) + 1

x = −2/9 + 1

x = −2/9 + 9/9

x = 7/9

Therefore, the solution to the system is x = 7/9 and y = 1/9.

Answer: n = g/5

Step-by-step explanation:

X=33/17

Here is how it works

By the way what you are working with is called improper factions, which is when the big number is placed over the smaller number.

Now 33/17 is also 1 16/17

35/17 is also 2 1/17

Now we can the proper fractions which are 1 16/17 and 2 1/17

1+2=3 and 16/17 + 1/17 equals 1

Answer:

  No, the clay will not pour out easily. I know this because the angle of the truck bed is less than 50°, which is the minimum angle for easy pouring.

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

  Sin = Opposite/Hypotenuse

If α represents the angle of the truck bed, this means ...

  sin(α) = 9/15

We can find α using the inverse sine function:

  α = arcsin(9/15) ≈ 36.87°

We note this angle is less than 50° so we expect the clay will not pour out easily.

Using the tangent function of trigonometry, we find that the angle of the raised dump truck is approximately 30.96°. Since this is less than the necessary 50°, the clay will not pour out easily when the dump truck is raised to 9 feet.

In order to solve this problem, we need to use trigonometry, specifically the tangent function. We form a right triangle, using the truck's bed length (15 feet) as the hypotenuse, the height it's been lifted (9 feet) as the opposite, and we want to find the angle this makes with the ground.

We use the relationship in trigonometry: Tan(angle) = Opposite/Hypotenuse. Converting the values to this equation, Tan(angle) = 9/15. Solving this gives us the angle as the inverse tan of 9/15.

Using a calculator to find the Inverse tan (also known as arctan or tan^-1) of 9/15 gives us an angle, which is approximately 30.96°.

No, The clay will not pour out easily when the body of the dump truck is raised to 9 feet. I know this because the body angle of the dump truck (approximately 30.96°) is less than the necessary 50° for the clay to pour out easily.
