A bank teller hourly wage will increase from $18 to $21.60. What percent increase does this represent?

Answer:

Step-by-step explanation:

The line contains the points (0,3) and (6,11).

first find the slope with slope formula.
m=(11-3)/(6-3)

=8/2

=4.

you know the y-intercept is 3, so use slope-intercept form

y=4x+3

for a ratonal, the expression only makes sense if the denominator is not 0, since if that occurs then the expression becomes undefined, a division by 0 is always undefined, for this case, when does that occur?  Let's set the denominator to 0 and solve for "x".

\(\cfrac{\sqrt{2}}{\sqrt{x-1}} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{setting the denominator to 0}}{\sqrt{x-1}=0\implies (\sqrt{x-1})^2=0^2}\implies x-1=0\implies x=1\)

well then, let's see what happens when x = 1

\(\cfrac{\sqrt{2}}{\sqrt{x-1}}\implies \cfrac{\sqrt{2(1)}}{\sqrt{1-1}}\implies \cfrac{\sqrt{2}}{\sqrt{0}}\implies \cfrac{\sqrt{2}}{0}\leftarrow und efined\)

so the only values that makes sense is anything but x < 1, because a smaller value of 1 will give us an imaginary value from the root, so the only values that makes sense are namely { x | x ∈ ℝ; x > 1 }

The box in the middle of the plot spans from the first quartile (Q1) to the third quartile (Q3), with a line inside representing the median.

A whisker plot, also known as a box and whisker plot, is a graphical representation of a set of numerical data through their quartiles. The plot consists of a box with whiskers extending from the top and bottom, showing the spread and distribution of the data. The five-number summary, which includes the minimum value, first quartile (Q1), median, third quartile (Q3), and maximum value, is used to create the whisker plot.

Here,

To create a box and whisker plot, we need to find the five-number summary of the data set, which includes:

Minimum value: the smallest value in the data set.

First quartile (Q1): the median of the lower half of the data set.

Median: the middle value in the data set.

Third quartile (Q3): the median of the upper half of the data set.

Maximum value: the largest value in the data set.

First, we need to put the data in order:

10, 12, 14, 15, 16, 18, 22, 24, 25, 28

The minimum value is 10 and the maximum value is 28.

The median is the middle value, which is 18.

To find the first quartile, we need to find the median of the lower half of the data set, which is:

10, 12, 14, 15, 16

The median of this lower half is 14.

To find the third quartile, we need to find the median of the upper half of the data set, which is:

22, 24, 25, 28

The median of this upper half is 24.

So, the five-number summary for this data set is:

Minimum value = 10

First quartile (Q1) = 14

Median = 18

Third quartile (Q3) = 24

Maximum value = 28

Now we can use this information to create the box and whisker plot:

      |          |      

 ----+----+----+----+----

    10   14   18   24   28

The box in the middle of the plot spans from the first quartile (Q1) to the third quartile (Q3), with a line inside representing the median. The whiskers extend from the box to the minimum and maximum values in the data set.

the area of the circular plate is approximately 63.62 square inches.

The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

Given, A circular plate has a circumference of 28.3 inches.

The circumference of a circle is given by the formula:

C = 2πr

where C is the circumference,

π (pi) is a constant approximately equal to 3.14,

and r is the radius of the circle.

In this case, we are given the circumference of the circle, which is 28.3 inches. So we can use the formula to solve for the radius:

28.3 = 2πr

r = 28.3 / (2π)

r ≈ 4.5

Now that we know the radius is approximately 4.5 inches, we can use the formula for the area of a circle:

A = πr²

Plugging in the value of r, we get:

A = 3.14 x 4.5²

A ≈ 63.62

So the area of the circular plate is approximately 63.62 square inches.

The monthly Payment for the loan is approximately $271.24.

To calculate the monthly payment for the loan, we can use the formula for calculating the monthly payment on an intermediate-term loan. The formula is:

Monthly Payment = (Loan Amount * Monthly Interest Rate) / (1 - (1 + Monthly Interest Rate)^(-Number of Months))

Given:

Loan Amount = $50,000

Interest Rate = 6.5% per year

Number of Years = 5

First, we need to convert the annual interest rate to a monthly interest rate. Since there are 12 months in a year, the monthly interest rate is:

Monthly Interest Rate = (6.5% / 100) / 12 = 0.00541667

Plugging in the values into the formula, we get:

Monthly Payment = ($50,000 * 0.00541667) / (1 - (1 + 0.00541667)^(-5 * 12))

              = $271.24

Therefore, the monthly payment for the loan is approximately $271.24.

The owners of the restaurant want to use the loan to renovate the kitchen and expand the dining room, which they expect will generate additional monthly revenue between $2,000 and $5,000.

If we assume a conservative estimate of $2,000 per month in additional revenue, the loan payment of $271.24 represents approximately 13.56% of the additional revenue. This means that the owners would still have a significant portion of the additional revenue available for other expenses or profit.

On the other hand, if we consider the higher estimate of $5,000 per month in additional revenue, the loan payment would represent only about 5.42% of the additional revenue, leaving a substantial amount of money for other purposes.

Considering these calculations, it appears that taking this loan is a smart business decision. The monthly payment is manageable and leaves a significant portion of the additional revenue for the restaurant's operation and potential profit. However, it is essential for the owners to ensure that the projected additional revenue is realistic and sustainable to cover the loan payment and other business expenses.

The most appropriate measure of center for this data would be the median of 49.

The reason for this is that the data is skewed, with a cluster of higher donations between 45 and 50, and only a few donations in the lower range. The mean can be affected by outliers, and in this case, the presence of the two donations of 11 and 18 can skew the mean downwards. Therefore, the median, which is the middle value of the data set when arranged in order, is a more appropriate measure of center for this skewed distribution.

In this case, the median of 49 represents the middle value of the data set and is not influenced by the extreme values at either end of the distribution. Therefore, the charity can use the median donation amount of 49 dollars to accurately represent the typical donations received.

The physical diameter of the sun will be 1309000km and the percentage of difference between the diameters will be 5.8%.

From the information, the sun has an angular diameter of about 0.5° and an average distance from the Earth of about 150 million km. The angular diameter in radians will be:

= 0.5π / 180

= 0.008727 radians

Distance from the sun = 150 × 10^6

The physical diameter of the sun will be:

= 150 × 10^6 × 0.008727

= 1309000km

The difference between the diameters will be:

= 1390000 - 1309000

= 8.1 × 10^4.

The percentage of difference will be:

Applying the tangent and the circle theorems, we have:

22. x ≈ 9.4;   23. Perimeter of triangle GHI = 168 units

24. m<NSR = 110°;    25. x = 10

22. Based on the tangent theorem, the triangle is a right triangle since the line is tangent to the radius of the circle. Therefore, based on the Pythagorean theorem, we have:

x = √[(7.4 + 4.6)² - 7.4²]

x ≈ 9.4

23. JH and HK are tangents, therefore they are equal. Thus:

7x + 4 = 13x - 20

7x - 13x = -4 - 20

-6x = -24

x = 4

Perimeter = GI + GJ + JH + HK + KI

GI = 52

HK = JH = 7x + 4 = 7(4) + 4 = 32

KI = 15

GJ = 52 - 15 = 37

Perimeter of triangle GHI = 52 + 37 + 32 + 32 + 15 = 168 units

24. Based on the angle of intersecting chords theorem, we have:

m<NSR = 1/2(170 + 50)

m<NSR = 110°

25. Based on the inscribed angle theorem, we have:

2(4x - 5) + 290 = 360

Solve for x:

8x - 10 + 290 = 360

D. A pair of intersecting lines

Step-by-step explanation:

A conic section is a fancy name for a curve that you get when you slice a double cone with a plane. Imagine you have two ice cream cones stuck together at the tips, and you cut them with a knife. Depending on how you cut them, you can get different shapes. These shapes are called conic sections, and they include circles, ellipses, parabolas and hyperbolas. If you cut them right at the tip, you get a point. If you cut them slightly above the tip, you get a line. If you cut them at an angle, you get two lines that cross each other. That's what happened in your question. The plane cut the cone at an angle, so the curve is two intersecting lines. That means the correct answer is D. A pair of intersecting lines.

What is Algebraic expression ?

An algebraic expression is a mathematical expression that contains one or more variables, as well as numbers and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots. It represents a mathematical relationship or rule and can be used to describe or represent quantities that can vary.

The equations that are true for x = -2 and x = 2 are:

\(x^{2}\)  – 4 = 0

This equation becomes (-2)2 - 4 = 0, which simplifies to 4 - 4 = 0, and it is true.

4 \(x^{2}\)  = 16

This equation becomes 4(-2)2 = 16, which simplifies to 4(4) = 16, and it is also true.

So, the correct options are:

\(x^{2}\)  – 4 = 0

4 \(x^{2}\)  = 16

Note: The other options are not true for x = -2 and x = 2. For example, x2 = -4 is not true for real numbers since the square of a real number cannot be negative. 3x2 + 12 = 0 is not true for x = -2 and x = 2, as it becomes 3(-2)2 + 12 = 0 which simplifies to 12 + 12 = 0, which is false. And 2(x - 2)2 = 0 is not true for x = 2, as it becomes 2(2 - 2)2 = 0, which simplifies to 0 = 0, and it is true, but it is not true for x = -2.

So, the correct options are  \(x^{2}\)  – 4 = 0 and 4 \(x^{2}\)  = 16.

So, the circumference of the table is:

C = πd

C = π(3)

C = 9.42 feet (rounded to the nearest tenth)

Therefore, the circumference of the table to the nearest tenth is 9.4 feet.

Step-by-step explanation:

12) Angles of a triangle add up to 180°.

m∠P + m∠Q + m∠R = 180

5x − 14 + x − 5 + 2x − 9 = 180

8x − 28 = 180

8x = 208

x = 26

m∠P = 5x − 14 = 116

m∠Q = x − 5 = 21

m∠R = 2x − 9 = 43

14) If two sides of a triangle are equal, then the angles opposite those sides are also equal.

(Conversely, if two angles are equal, then the sides opposite those angles are also equal.  Such a triangle is called an isosceles triangle.)

BC ≅ BD, so m∠C = m∠D.

5x − 19 = 2x + 14

3x = 33

x = 11

m∠B = 13x − 35 = 108

m∠C = 5x − 19 = 36

m∠D = 2x + 14 = 36
