Answer:

A glide reflection is a composition of transformations.In a glide reflection, a translation is first performed on the figure, then it is reflected over a line. Therefore, the only required information is the translation rule and a line to reflect over. ... The first one is a translation rule.

Final answer:

In a glide reflection, the translation occurs first, moving the figure along a straight line, followed by a reflection over a line parallel to the translation vector, resulting in a figure that has been moved and potentially reoriented.

Explanation:

In a glide reflection, a transformation that combines a translation with a reflection, the proper sequence is important. The translation part comes first, where the figure is slid along a straight line called the translation vector. After the figure has been moved, the second step is the reflection over a line parallel to the vector of the translation. This two-step process results in a final image that has the same size and shape as the original figure but is in a different position and may have a different orientation.

Imagine a point undergoing a glide reflection. Initially, it is translated along a vector, and then it is reflected across a line that is parallel to the direction of translation. The end result is that the point has 'glided' to a new location, as if it had slid across a mirror placed at an angle to its original path.

Answer:

The missing coefficient of the x-term of the product (-x-5)2 is 10.

Step-by-step explanation:

Through whole square formula.

(-x-5)2 = (-x)^2 -2(-x)(5)+(5)^2

=x^2+10x+25

Therefore, the missing coefficient of the x-term of the product is 10

Answer:

10

Step-by-step explanation:

The given expression is

[tex](-x-5)^2[/tex]

We need to find the coefficient of x.

According to the property of algebra.

[tex](a-b)^2=a^2-2ab+b^2[/tex]

In the given expression a=-x and b=5.

Substitute a=-x and b=5 in the above formula.

[tex](-x-5)^2=(-x)^2-2(-x)(5)+(5)^2[/tex]

On further simplification we get

[tex](-x-5)^2=x^2+10x+25[/tex]

Coefficient of x is a multiplicative factor of x.

Therefore, the coefficient of x is 10.

Answer:

| x - 0 | ≤ 2

Step-by-step explanation:

Given,

The ideal temperature of the freezer = 0° F,

Also, it can fluctuate by 2° F,

Thus, if x represents the temperature of the freezer,

Then, there can be two cases,

Case 1 : x > 0,

⇒ x - 0 ≤ 2

Case 2 : If x < 0,

⇒ 0 - x ≤ 2,

⇒ -( x - 0 ) ≤ 2,

By combining the inequalities,

We get,

| x - 0 | ≤ 2,

Which is the required inequality.

Answer:

[tex]\sqrt[6]{200}[/tex]

Step-by-step explanation:

First of all, you need to know that you cannot multiply those radicals without having a common index (the little number outside the radical that sits in the curve of the radical).  One is a 3 and the other, without being stated outright, is understood to be a 2.  BUT we can make them like.  The index of a radical is the denominator of the exponential equivalent.  

[tex]\sqrt[3]{5}=5^{\frac{1}{3}}[/tex] and

[tex]\sqrt{2}=2^{\frac{1}{2}}[/tex]

See how the indexes are now the denominators of the rational exponents.  We can make them like by finding the LCM of 3 and 2...which is 6:

[tex]5^{\frac{1}{3}}=5^{\frac{2}{6}}[/tex] and

[tex]2^{\frac{1}{2}}= 2^{\frac{3}{6}}[/tex]

Now that the indexes are like, we rewrite them as radicals again:

[tex]\sqrt[6]{5^2}*\sqrt[6]{2^3}[/tex] which, simplified, is

[tex]\sqrt[6]{25}*\sqrt[6]{8}[/tex]

Now we can find the product which is

[tex]\sqrt[6]{200}[/tex]

The product of ∛5 ×√2 is approximately 2.41. The correct option is b) [tex]\sqrt[6]{200}[/tex], which matches the calculated value.

To find the product ∛5 × √2, we first take the cube root of 5 (∛5) and then multiply it by the square root of 2 (√2).

∛5 ≈ 1.71 (approximately, rounded to two decimal places)

√2 ≈ 1.41 (approximately, rounded to two decimal places)

Now, let's calculate the product:

∛5 × √2 ≈ 1.71 × 1.41 ≈ 2.41 (approximately, rounded to two decimal places)

Now, let's check the options:

a. [tex]\sqrt[6]{10}[/tex] ≈ 1.72 (approximately, rounded to two decimal places)

Final answer:

The angle 237° is located in the third quadrant since it is between 180° and 270°.Therefore, the correct answer to the question is:

D. III

Explanation:

The question asks in which quadrant the angle 237° is located. To determine the quadrant of an angle in standard position (angle measured from the positive x-axis), we use the following information:

Angles from 0° to 90° are in the first quadrant.

Angles from 90° to 180° are in the second quadrant.

Angles from 180° to 270° are in the third quadrant.

Angles from 270° to 360° are in the fourth quadrant.

Since 237° is between 180° and 270°, it is located in the third quadrant. Therefore, the correct answer to the question is:

D. III

Answer:

  183.7 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that the relation between the hypotenuse and opposite side in a right triangle is ...

  Sin = Opposite/Hypotenuse

For the first observation, the angle is 45° and the length of the hypotenuse of the triangle is given as x. For the second observation, the opposite side (building height) is the same, the angle is 60°, and the hypotenuse is 150 ft.

We can multiply the above equation by "Hypotenuse" to get an expression for "Opposite".

  Opposite = Sin×Hypotenuse

For our two observations, this becomes ...

  sin(45°)·x = (building height) = sin(60°)·(150 ft)

Dividing by the coefficient of x, we have ...

  x = (150 ft)·sin(60°)/sin(45°) ≈ 183.7 ft

Answer:

B: 183.7

Step-by-step explanation:

First we need to find our values

A = 45°

B = 180 - 60 = 120

a = 150

Then we can solve for x using this formula x = a * sin(B)/sin(A).

x = 150 * sin(120)/sin(45)

x = 150 * √6/2

x = 75√6

x = 183.71173

The z-score for a student who scored 75 on the test with an average of 80 and a standard deviation of 6 is approximately -0.833, indicating the score is 0.833 standard deviations below the mean.

To calculate the z-score for a student who scored 75 on a history test, we can use the z-score formula:

[tex]Z = \( \frac{X - \mu}{\sigma} \)[/tex]

Where:

X is the raw score (75 in this case)

[tex]\( \mu \)[/tex] is the mean score (80)

[tex]\( \sigma \)[/tex] is the standard deviation (6)

Inserting the values, we get:

[tex]Z = \( \frac{75 - 80}{6} \) = \( \frac{-5}{6} \) = -0.833\[/tex]

The z-score for a student who earned 75 on the test is approximately -0.833, rounded to the nearest thousandth. This z-score indicates that the student's score is about 0.833 standard deviations below the mean

Answer:

{2, 2, -6}

Step-by-step explanation:

synthetic division is one of the easier ways of determining whether or not a given number is a root of a polynomial.  Here we're told that -6 is a root.  Let's go through the steps of synthetic division:  keep in mind that if there is no remainder (that is, the remainder is zero), then the divisor (such as -6) is a zero of the polynomial.

The coefficients of f(x)=x^3+2x^2-20x+24 are {1, 2, -20, 24}.

Setting up synthetic div.:

       -6   )   1    2    -20    24

                      -6     24    -24

             ----------------------------

                 1    -4       4     0

Here the remainder is zero (0), so it is safe to assume that -6 is a zero of the original polynomial.

We can continue with synth. div. to determine the remaining zeros of the original function  f(x)=x^3+2x^2-20x+24.   The coefficients {1,  -4,  4} represent the quadratic x^2 - 4x + 4.  Let's check whether the factor 2 of 4 is indeed a zero:

2   )   1    -4    4

               2   -4

    -----------------

       1      -2    0

Here the remainder is zero.  Thus, 2 is a zero of f(x)=x^3+2x^2-20x+24.  Notice that the remaining coefficients are {1, -2}; they represent x - 2 = 0, so the third root is 2.

Thus, the zeros of f(x)=x^3+2x^2-20x+24 are {2, 2, -6}

There are a total of 2,000 students in the school.

1.) There are 540 students in the 6th grade. 540 is only 27% of students compared to the total. To find the total students in the whole school, we divide 540 by 27%.

2.) We first change 27% into a decimal by moving the point two times to the left. (Rule to change the percent into a decimal)

27% = .27

3.) Before we divide, we remove the decimal by moving the decimal two times to the right and so do we to 540.

.27 = 27

540. = 54000.

4.) Now we have 54000 divided by 27 which give us the answer of 2,000.

Answer:

276.75

Step-by-step explanation:

Deposit 1230. paying 2.25 % 10 yrs.

the interest is 276.75 and the amount is 1506.75

Answer:

The answer to the first question is $276.75     and the answer to the second question is $4882.50

Step-by-step explanation:

Johnny deposited $1230 in a savings account at 2.25 percent interest. How much interest will the account earn in 10 years?

To solve this, we simply use the simple interest formula;

Simple Interest = PRT / 100

where p is the principal, R is the rate and T is the time (in years)

In this question principal = $1230  rate = 2.25   and time = 10

We can now plug the variables into the formula;

Simple Interest = PRT / 100

                           =$1230  × 2.25× 10    /     100

                             = $27675  / 100

                              = $276.75

Therefore, the amount of interest earn in 10 years is  $276.75

Will got an insurance check of $4500 after a car accident. He deposited it into a savings  account at 1.7 percent interest for five years. What was the total amount of money in the  account after five years?

We can also solve this second part of the question using the simple interest formula, here;

principal = $4500

Rate =1.7

Time =5

We will now insert our values into the simple interest formula, thus;

Simple Interest = PRT / 100

                          =$4500 × 1.7 × 5   / 100

                          =$38250 / 100

                          =$382.50

Simple interest =$382.50

Total amount = $4500 + $382.50

                      =$4882.50

Therefore, the total amount in the account after five years is $4882.50

Final answer:

Using the Rational Root Theorem, the polynomial equation 2x⁴+ 4x³-6x²+15x-12=0 has 12 distinct possible rational roots, where factors of the constant term are divided by factors of the leading coefficient.

Explanation:

To determine the number of possible rational roots for the polynomial equation 2x⁴+4x³−6x²+15x−12=0, we can use the Rational Root Theorem. This theorem states that if the polynomial has any rational roots, they must be of the form ±p/q, where p is a factor of the constant term and q is a factor of the leading coefficient.

The constant term in this case is -12, and its factors are ±1, ±2, ±3, ±4, ±6, and ±12. The leading coefficient is 2, and its factors are ±1 and ±2.

Thus, the possible rational roots are combinations of the factors of -12 divided by the factors of 2, giving us ±1, ±2, ±3, ±4, ±6, and ±12 combined with ±1 and ±2. So, our possible rational roots are: ±1/1, ±2/1, ±3/1, ±4/1, ±6/1, ±12/1, ±1/2, ±2/2, ±3/2, ±4/2, ±6/2, and ±12/2 which simplifies to ±1/1, ±2, ±3, ±4, ±6, ±12, ±1/2, ±3/2, and ±6/2.

After simplification, there is a total of 12 distinct possible rational roots, corresponding to option D.

Phone and Tablet Storage Measurement

Let's break down each part of the question to help Theresa and her family understand the storage capacity in bits.

Part A

Theresa and Ruben's phones each have 32 gigabytes (GB) of storage. To find the number of bits:

→ Convert gigabytes to bytes: 32 GB = 32 × 1024 × 1024 × 1024 bytes.

→ Convert bytes to bits (since 1 byte = 8 bits): 32 × 1024 × 1024 × 1024 × 8 bits.

→ Calculate the value: 32 × 1024 × 1024 × 1024 × 8 = 274,877,906,944 bits.

→ In scientific notation, this is approximately 2.75 × 10¹¹ bits.

Part B

Cal and Julia's phones each have 64 gigabytes (GB) of storage:

→ Convert gigabytes to bytes: 64 GB = 64 × 1024 × 1024 × 1024 bytes.

→ Convert bytes to bits: 64 × 1024 × 1024 × 1024 × 8 bits.

→ Calculate the value: 64 × 1024 × 1024 × 1024 × 8 = 549,755,813,888 bits.

→ In scientific notation, this is approximately 5.50 × 10¹¹ bits.

Part C

The family gets two free tablets with 16 gigabytes (GB) of storage each:

→ Convert gigabytes to bytes: 16 GB = 16 × 1024 × 1024 × 1024 bytes.

→ Convert bytes to bits: 16 × 1024 × 1024 × 1024 × 8 bits.

→ Calculate the value: 16 × 1024 × 1024 × 1024 × 8 = 137,438,953,472 bits.

→ In scientific notation, this is approximately 1.37 × 10¹¹ bits.

Part D

Theresa and Ruben each get 8-gigabyte (GB) SD cards:

→ Convert gigabytes to bytes: 8 GB = 8 × 1024 × 1024 × 1024 bytes.

→ Convert bytes to bits: 8 × 1024 × 1024 × 1024 × 8 bits.

→ Calculate the value: 8 × 1024 × 1024 × 1024 × 8 = 68,719,476,736 bits.

→ In scientific notation, this is approximately 6.87 × 10¹⁰ bits.

Part E

The family gets 40 gigabytes (GB) of cloud storage:

→ Convert gigabytes to bytes: 40 GB = 40 × 1024 × 1024 × 1024 bytes.

→ Convert bytes to bits: 40 × 1024 × 1024 × 1024 × 8 bits.

→ Calculate the value: 40 × 1024 × 1024 × 1024 × 8 = 343,597,383,680 bits.

→ In scientific notation, this is approximately 3.44 × 10¹¹ bits.

Answer:

a = -4

b = 6

Step-by-step explanation:

See attached

Answer:

a=-4 and b=6

Step-by-step explanation:

[tex]\frac{a}{x-8} +\frac{b}{x+4} =\frac{2x-64}{(x-8)(x+4)}[/tex]

First, add the fractions by finding the common denominator.

In this case, (x-8)(x+4).

[tex]\frac{a(x+4) + b(x-8)}{(x-8)(x+4)} =\frac{2x-64}{(x-8)(x+4)}[/tex]

Therefore, the numerators are equal:

[tex]a(x+4) + b(x-8) =2x-64[/tex]

Simplify:

[tex]ax+4a + bx-8b =2x-64\\(a+b)x+4a-8b=2x-64[/tex]

Now match the coefficients.

[tex]a+b=2, 4a-8b=-64[/tex]

Solve the system of equations.  I'll use substitution, but you can also use elimination if you prefer.

[tex]4a-8b=-64\\a-2b=-16\\(2-b)-2b=-16\\2-3b=-16\\-3b=-18\\b=6\\a=-4[/tex]

Therefore, a=-4 and b=6.

ANSWER

Point-slope form:

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

Slope-intercept form:

[tex]y= -\frac{3}{5} x + \frac{9}{5}[/tex]

EXPLANATION

The graphed line passes through

[tex](-2,3) \: \: and \: \: (3,0)[/tex]

The slope of this line is determined using

[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]

We substitute the points to get;

[tex]m = \frac{0 - 3}{3 - - 2} [/tex]

[tex]m = -\frac{3}{5} [/tex]

The point-slope formula is:

[tex]y-y_1 = m(x - x_1)[/tex]

Substitute the first point and slope to get:

[tex]y - 3 = -\frac{3}{5} (x - - 2)[/tex]

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

To find the slope-intercept form, we expand to get:

[tex]y= -\frac{3}{5} x - \frac{6}{5} + 3[/tex]

[tex]y= -\frac{3}{5} x + \frac{9}{5} [/tex]

Answer:

Slope

[tex]m=-\frac{3}{5}[/tex]

point-slope form

[tex]y=-\frac{3}{5}(x-3)[/tex]

slope-intersection form

[tex]y=-\frac{3}{5}x+1.8[/tex]

Step-by-step explanation:

The equation of a line in the point-slope form has the following formula:

[tex]y-y_0 = m (x-x_0)[/tex]

Where m is the slope and [tex](x_0, y_0)[/tex] is a point belonging to the line.

The equation of a line in the slope-intersection form has the following formula:

[tex]y = mx + b[/tex]

Where b is the intersection of the line with the y axis.

To calculate the slope of the line knowing 2 points we use the following formula:

[tex]m=\frac{y_1-y_0}{x_1-x_0}[/tex]

In this case:

[tex]x_0 =3\\y_0=0\\x_1=-2\\y_1=3[/tex]

So

[tex]m=\frac{3-0}{-2-3}[/tex]

[tex]m=-\frac{3}{5}[/tex]

So the equation of a line in the point-slope form

[tex]y-0 =-\frac{3}{5}(x-3)[/tex]

[tex]y=-\frac{3}{5}(x-3)[/tex]

The equation of a line in the slope-intersection form is:

[tex]y-0=-\frac{3}{5}(x-3)[/tex]

[tex]y=-\frac{3}{5}(x-3)[/tex]

[tex]y=-\frac{3}{5}x+\frac{9}{5}[/tex]

[tex]y=-\frac{3}{5}x+1.8[/tex]

with [tex]b=1.8[/tex]

If we want to change it to a mixed number

x = 1 9/14

Step-by-step explanation:

42x – 5 = 64

Add 5 to each side

42x – 5+5 = 64+5

42x = 69

Divide each side by 42

42x/42 = 69/42

x = 69/42

Divide the top and bottom by 3

x =23/14

If we want to change it to a mixed number

x = 1 9/14

Answer:

d)4

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

y = 2x² + 8x + 3

Complete the square:

y = 2(x² + 4x) + 3

y = 2(x² + 4x + 4) + 3 - 2(4)

y = 2(x + 2)² - 5

So the vertex is at (-2, -5).  The graph must be Graph A.

Graph A has its vertex at (-4, -5). Then the correct option is A.

It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.

The parabolic expression is given below.

y = 2x² + 8x + 3

y = 2(x² + 4x) + 3

y = 2(x² + 4x + 4) - 8 + 3

y = 2(x + 4)² -5

The vertex of the parabola is at (-4, -5).

Graph A has its vertex at (-4, -5). Then the correct option is A.

Then the graph of the parabola is given below.

Answer:  101 revolutions

Step-by-step explanation:

Answer:  The total number of revolutions is 101.

Step-by-step explanation:  Given that the wheels on Jason's dirt bike measure 19 inches in diameter.

We are to find the number of revolutions that the wheels make when Jason rides for 500 feet.

We know

1 foot = 12 inches.

So, 500 feet = 12 × 500 = 6000 inches.

Now, diameter of the wheels is given by

d = 19 inches.

So, the circumference of the wheels will be

[tex]C=\pi d=3.14\times19=59.66~\textup{inches}.[/tex]

Therefore, to ride 500 feet, The number of revolutions that the wheels make is given by

[tex]n=\dfrac{6000}{59.66}=100.56989...[/tex]

Rounding to the nearest whole number, the required number of revolutions will be 101.

Thus, the total number of revolutions is 101.

Answer: [tex]7m^5-3m^3-3[/tex]

Step-by-step explanation:

You can observe that you need to subtract the polynomial [tex](6m^5 + 3 - m^3 -4m)[/tex] and the polynomial [tex](-m^5 + 2m^3- 4m + 6)[/tex].

It is important the remember the multiplication of signs:

[tex](+)(+)=+\\(-)(-)=+\\(+)(-)=-[/tex]

Then, the first step is to distribute the negative sign:

[tex](6m^5 + 3 - m^3 -4m)-(-m^5 + 2m^3- 4m + 6)=\\=6m^5 + 3 - m^3 -4m+m^5-2m^3+ 4m- 6[/tex]

And finally you must add the like terms. Then:

[tex]=7m^5-3m^3-3[/tex]

Answer:

  $1,000 at 2%; $1,800 at 4%

Step-by-step explanation:

Let x represent the amount invested at 2%. Then x+800 was invested at 4% and the total interest earned was ...

  x·2% + (x+800)·4% = 92

  x·6% + 32 = 92 . . . . . . . . . simplify

  x·0.06 = 60 . . . . . . . . . . . . subtract 32; write 6% as a decimal

  x = 60/0.06 = 1000 . . . . . divide by the coefficient of x

$1000 was invested at 2%; $1800 was invested at 4%.
