The resulting transformation is a combination of rotation and translation.

The resulting R'ST' is an example of a Rotation and Translation.

In a rotation, an object is turned or twisted around a fixed point. In this case, R'ST' is rotated around a specific point.

A translation refers to the sliding of an object in a particular direction.

In this case, R'ST' is also shifted or translated in a specific direction.

Therefore, the resulting transformation is a combination of rotation and translation.

-$1.71

To find the average of a set of numbers, you add them all together and divide by the amount of numbers.

Start by adding the numbers together to get -8.55.

Since they are 5 numbers, divide -8.55 by 5 to get -1.71.

So, the average daily change of the stock’s value is -$1.71.

Answer:

D

Step-by-step explanation:

This graph shows two vertical asymptotes, one at x = +3, the other at x = 4.  Thus, we omit the first two answer choices.  Next, we substitute 0 for x and determine the y value in Answer Choice C:  F(0) = 0.  Does the graph go through (0, 0)?  Yes, it does.  Next, evaluate F at x = 3.5 (halfway between x =  3 and x = 4); that is, evaluate function D at x = 3.5.  Does the y value come out to be -4 as shown in the graph?  Yes, it does.    So D is the correct function to match this graph.

Considering the vertical asymptotes of the function, and it's behavior, it is found that the rational function graphed below is given by:

D. [tex]f(x) = \frac{1}{(x - 3)(x - 4)}[/tex]

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.

Answer:

4,582,500

Step-by-step explanation:

(30,000*611)/4=4,582,500

Answer:

Quarterly budget of $4582500 must be allocated.

Step-by-step explanation:

A facility spends on its inmates of an average = $30000 annually

Number of inmates = 611

Total amount to be spent = $30000×611

= $18330000

Since there are 4 quarters in a year so quarterly budget allocated

= [tex]\frac{18330000}{4}[/tex]

= $4582500

Therefore, quarterly budget of $4582500 should be allocated.

The mode in a stem-and-leaf plot is determined by identifying which leaf (end digit of a data point) occurs most often for a particular stem (leading digit(s)). For example, in the data set 4, 5, 6, 6, 6, 7, 7, 7, 7, 7, 7, 8, 8, 8, 9, 10 the mode is 7 as it appears most frequently.

The stem-and-leaf plot is a type of graph that provides a visual representation of data. It is a way of organizing data in which we can easily discover the mode, mean, median, and even the shape of the distribution (such as skewness). The mode in a data set is the value that appears the most often. In the context of a stem-and-leaf plot, identifying the mode involves finding which 'leaf' or end digit of a data point (the last digit in a number) occurs most frequently on a particular 'stem' or leading digit (all but the last digit of a number).

For example, in the stem-and-leaf plot of the data set given : 4, 5, 6, 6, 6, 7, 7, 7, 7, 7, 7, 8, 8, 8, 9, 10 the mode is 7 as the number '7' shows up the most often, which is 6 times. For identifying the mode, we closely look at the list of leaf values for each stem value and determine which leaf occurs more frequently than any other. Therefore, to answer the student's question about finding the mode from a stem-and-leaf plot, they simply need to identify which leaf value occurs most frequently in the data set presented in the plot.

Ava and Kelly will be 3/4 mile apart after 22.5 minutes of running at their respective speeds of 6 mph for Ava and 8 mph for Kelly.

To determine when Ava and Kelly will be 3/4 mile apart in a road race, we must calculate the difference in distance they cover over the same time frame. Ava runs at 6 miles per hour (mph) and Kelly runs at 8 miles per hour (mph). The difference in their speeds is 2 mph (8 mph - 6 mph).

We need to calculate the time it takes for this difference in speed to result in a gap of 3/4 miles. Since speed is distance divided by time, we can use the formula:
Time = Distance / Speed. Substituting the values we have, we get:
Time = (3/4) miles / 2 mph. When we calculate this, we find the time to be 3/8 hours, or 22.5 minutes.

Therefore, Ava and Kelly will be 3/4 mile apart after 22.5 minutes of running at their respective average speeds.

Answer:$400

Step-by-step explanation:

Because, if she spent ONLY 1/5 of her money, and she has $80 left, wouldn't you basically have to multiply 5 with 80 to get the original amount of money?

Answer:

$100

Step-by-step explanation:

If Maryna had $80 after spending 1/5, we know she has 4/5 left. Then, we divide 80 by 4/5. To divide a fraction, we multiply the number by rhe reciprocal. So, we multiply 80/1 by 5/4. 80 multiplied by 5 is 400, and divided by 4 is 100. This is how we get an original amount of $100.

Answer:

x = 11, y = 8

Step-by-step explanation:

ΔABC and ΔFDE are congruent by the postulate SSS

Equate the congruent sides in the 2 triangles

BC = ED, that is

x + 3 = 14 ( subtract 3 from both sides )

x = 11

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

DF = AB, that is

x - y = 3 ← substitute x = 11

11 - y = 3 ( subtract 11 from both sides )

- y = 3 - 11 = - 8 ( multiply both sides by - 1 )

y = 8

Answer:

The value of x is 11 and the value of y is 8.

Step-by-step explanation:

It is given that ∆ABC and ∆FDE are congruent.

The corresponding parts of congruent triangle are congruent.

[tex]AB=FD[/tex]                       (CPCTC)

[tex]3=x-y[/tex]                 .... (1)

[tex]BC=DE[/tex]                       (CPCTC)

[tex]x+3=14[/tex]

Subtract 3 from both the sides.

[tex]x=14-3[/tex]

[tex]x=11[/tex]

The value of x is 11.

Put x=11 in equation (1).

[tex]3=11-y[/tex]

Add y on both the sides.

[tex]3+y=11[/tex]

Subtract 3 from both the sides.

[tex]y=11-3[/tex]

[tex]y=8[/tex]

The value of y is 8.

The k-th root's inverse function is raising to the k-th power.

So, if we raise the k-th root of some number x to the k-th power, we have applied a function and its inverse to x, and we must get x itself as output:

[tex]f(f^{-1}(x))=f^{-1}(f(x))=x\quad\text{for every invertible function f}[/tex]

So, in our case, we have

[tex](\sqrt[k]{x})^k = \left(x^{\frac{1}{k}}\right)^k=x^{k\cdot \frac{1}{k}}=x^1=x[/tex]

The equation that Arlene claim should be [tex]x^{k.\frac{1}{k}} \ = x^1 = x[/tex]

The k-th root's inverse function should be raising with respect to the k-th power.

Thus, in the case if we raise the k-th root of some number x to the k-th power, so here we used the function and its inverse to x, and we must get x itself in an output:

So,

Given : f(x) = 5x² - 7(4x + 3)

Now,

f(3) = 5 × 3² - 7(4 × 3 + 3)

= 5 × 9 - 7(12 + 3)

= 45 - 7 × 15

= 45 - 105

= - 60

Hence,

f(3) = - 60

To find f(3) for the function f(x) = 5x² - 7(4x + 3), we substitute 3 into the function and simplify to get f(3) = -60.

To evaluate f(3) for the function f(x) = 5x² - 7(4x + 3), we need to substitute the value of 3 into the function:

f(3) = 5(3)² - 7(4(3) + 3)

Now we simplify the expression step by step:

The final result is:

f(3) = 45 - 105 = -60.

The answer is 125° = x because the exterior angle is 55°, from adding up all the exterior angles to ensure they add up to 360°. Then, you would have to use the Supplementary Angeles Theorem to find the obtuse measure beside that 55° exterior angle: 55 + m<x = 180. This is how you get 125° = m<x. You understand?

Answer:

The equation of the line is y = 4x

Step-by-step explanation:

* Lets revise how to form an equation of a line from its slope and

 a point on the line

- The equation of a line is written as y = mx + b where m is the

  slope of the line and b is the y-intercept.

- The line intersect the y-axis at point (0 , b)

* Lets solve the problem

- The line has slope = 4

- The line passes through the point (2 , 8)

∵ The slope = 4

∵ m is the slope of the line in the equation

∴ m = 4

- Substitute the value of m in the equation

∵ y = mx + b

∴ y = 4x + b

- To find the value of b substitute the x-coordinate and the

  y-coordinate of the point instead of x and y of the equation

∵ The point (2 , 8) lies on the line

∵ y = 4x + b

- Put x = 2 and y = 8 in the equation to find b

∴ 8 = 4(2) + b ⇒ simplify

∴ 8 = 8 + b ⇒ subtract 8 from both sides

∴ 0 = b

- That means the y-intercept = 0 and the line passing through

  the origin point

∴ y = 4x + 0

* The equation of the line is y = 4x

1 ) Watts =E * I = 110 * 5 = 550 watts =.55 KW  

2) I = Watts / e = 1100 / 110 = 10 amperes  

3) 1 horsepower = 33000 ft/lbs per minute  

HP = ( 2000 * 1000) / (33000 *4) = 15.1515 hp  

4) cost = (10 * 100 / 1000) *11 * $0.10 = $1.10  

5) This answer will be incorrect because you have not stated the power factor of the motor.  

va = I * E = 7.5 * 240 = 1800  

2 hp = 2 * 746 watts = 1492 watts  

If the motor had a 1.0 power factor (it doesn't) the efficiency would be  

efficiency = output / input = 1492 / 1800 = 82.888 %  

6) I = watts / E =1000 / 120 = 8.333 amps  

7) 1 = watts / E = 1000 / 240 = 4.1616  

8) Kw-hr = (2 * 24 * 365 ) / 1000 = 17.52  

cost = kw-hr * $0.03 = 17.52 * $0.03 = $0.5256  

9) efficiency = (115 * 240) / (2400 * 12) = 95.8333 %  

10) KW = (I^2 * R) / 1000 = (20^2 * 5) / 1000 = 2  

the current required is 10 amperes.

To calculate the current required for a device rated at 1,100 watts operating at 110 volts, we use the formula P = IV, where P is power in watts, I is current in amperes, and V is voltage in volts.

Rearranging the formula to solve for current, we get I = P / V. Plugging in the given values, we have:

I = 1,100 W / 110 V

Thus, the current required is 10 amperes.
