Answer: The square root of 45 is a like radical to 3 x √5.

To see why, we can simplify each radical using the product rule of radicals:

3 x √5 = √(3^2 x 5) = √45

Similarly, we can simplify the square root of 45 using the prime factorization of 45:

√45 = √(3 x 3 x 5) = 3√5

Therefore, 3 x √5 is a like radical to √45, and vice versa.

The dimensions of the rectangle are: length: 20 units and width: 3 units.

To solve the problem, we can set up an algebraic equation using the formula for the area of a rectangle, which is A = length × width.

Let x be the length of the rectangle, and x - 17 be the width.

Then we can set up the equation:

60 = x(x - 17)

Simplifying the equation gives us:

x² - 17x - 60 = 0

Now we can factor the equation:

(x - 20)(x + 3) = 0

This gives us two possible solutions for x:

x = 20 or x = -3

However, since the length of a rectangle cannot be negative, we can disregard the second solution.

Therefore, the length of the rectangle is 20 units, and the width is 20 - 17 = 3 units.

Mohal would expect to earn $265 in a day when he waits on 16 tables, and he would expect to earn $15tt + $25 in a day when he waits on tt tables

Earnings or wages refer to the amount of money an individual receives in exchange for their work or services. This can include a regular salary or hourly wage, as well as bonuses, commissions, and other forms of compensation.

Earnings or wages are typically determined by a variety of factors, including the type of work being performed, the level of skill and experience required, the local job market, and the employer's policies and practices. In some cases, earnings may be negotiated between the employer and the employee, while in other cases they may be set by industry standards or government regulations.

To calculate Mohal's expected earnings in a day when he waits on 16 tables, we can use the formula:

Total earnings = Guaranteed wage + Tips

Guaranteed wage = $25

Tips = $15 x Number of tables

Number of tables = 16

So, Total earnings with 16 tables = $25 + ($15 x 16) = $265

To calculate Mohal's expected earnings in a day when he waits on tt tables, we can use the same formula:

Total earnings = Guaranteed wage + Tips

Guaranteed wage = $25

Tips = $15 x Number of tables

Number of tables = tt

So, Total earnings with tt tables = $25 + ($15 x tt) = $15tt + $25

Therefore, Mohal would expect to earn $265 in a day when he waits on 16 tables, and he would expect to earn $15tt + $25 in a day when he waits on tt tables.

The vertices of the image of the triangle BCD are B'(x, y) = (- 3, 13), C'(x, y) = (0, 19) and D'(x, y) = (18, 10). The representation of the resulting figure is in the image attached below.

Herein we find the representation of a triangle on Cartesian plane, whose image, that is, the result of a dilation, must be found. The formula to be used is introduced below:

P'(x, y) = P(x, y) + k · [P(x, y) - O(x, y)]

Where:

If we know that B(x, y) = (- 3, 7), C(x, y) = (- 2, 9), D(x, y) = (4, 6), O(x, y) = (- 3, 4) and k = 2, then the coordinates of the vertices of the image are listed below:

B'(x, y) = (- 3, 7) + 2 · [(- 3, 7) - (- 3, 4)]

B'(x, y) = (- 3, 7) + 2 · (0, 3)

B'(x, y) = (- 3, 7) + (0, 6)

B'(x, y) = (- 3, 13)

C'(x, y) = (- 2, 9) + 2 · [(- 2, 9) - (- 3, 4)]

C'(x, y) = (- 2, 9) + 2 · (1, 5)

C'(x, y) = (- 2, 9) + (2, 10)

C'(x, y) = (0, 19)

D'(x, y) = (4, 6) + 2 · [(4, 6) - (- 3, 4)]

D'(x, y) = (4, 6) + 2 · (7, 2)

D'(x, y) = (4, 6) + (14, 4)

∠B=∠B.....common angles

∠BDE =∠BAC....corresponding angles

so, △BDE∼△ABC

Since △BDE and △ABC are similar so, corresponding sides will be in proportion,

Answer:

1 mile is equal to 1,760 yards. Therefore, 3 miles is equal to 3 x 1,760 = 5,280 yards.

Comparing 5,280 yards to 1,000 yards, we can see that 5,280 yards is greater than 1,000 yards.

To determine how much greater, we can subtract 1,000 from 5,280:

5,280 - 1,000 = 4,280

Therefore, 3 miles is 4,280 yards greater than 1,000 yards.

The cost per square foot of the remaining sheet metal is $4.10.

To find the cost per square foot of the remaining sheet metal, we can first calculate how much sheet metal is remaining by solving the equation:

7.6X - 3.5X = 65.6

where X is the amount of sheet metal remaining in square feet.

Simplifying the left side of the equation gives:

4.1X = 65.6

Dividing both sides by 4.1 gives:

X = 16

Therefore, the amount of sheet metal remaining is 16 square feet.

To find the cost per square foot, we can divide the cost of the remaining sheet metal by the amount of sheet metal remaining:

$65.60 / 16 sq. ft. = $4.10 per square foot.

A function is a mathematical rule that takes an input value and produces a unique output value. It can be thought of as a machine that transforms input values into output values.

The domain of the piecewise function g of x is (–∞, 2) ∪ (2, ∞), since the expression x squared plus 2 times x minus 8 is equal to zero when x is equal to negative 4 and 2, but the function is undefined at x equals negative 4 and x equals negative 5 due to the logarithmic function.

The electric field outside the pipe is E(r) = σa² / ε_0r².

The electric field inside the pipe is E(r) = σa²/ ε_0r.

Assuming the metallic pipe is infinitely long, we can use Gauss's Law to determine the electric field both inside and outside the pipe.

Let's consider a cylindrical Gaussian surface of radius r and length L, with its axis coinciding with that of the pipe.

By Gauss's Law, the electric flux through the surface is given by:

Φ_E = ∫ E . dA = E x 2πrL

where;

The charge enclosed by the Gaussian surface is given by:

Q_enc = σ x π(2a)² x L

= 4πa²σL

where;

By Gauss's Law, the electric flux through the Gaussian surface is also given by:

Φ_E = Q_enc / ε_0

where;

Equating the two expressions for Φ_E, we get:

E x 2πrL = 4πa²σL / ε_0

Simplifying, we get:

E = σa² / ε_0r for r < a

E = σa² / ε_0r^2 for r > a

Therefore, the electric field inside the pipe (r < a) is inversely proportional to the distance from the axis, while outside the pipe (r > a) it is inversely proportional to the square of the distance from the axis.

Outside the pipe: E(r) = σa² / ε_0r²

How to determine?

To find the area of each polygon, we need to use the formula for the area of each respective shape.

Assuming the polygons are rectangles, triangles, and trapezoids, we can find their areas as follows:

The area of the rectangle with length 9 ft and width 6 ft is A = length × width = 9 ft × 6 ft = 54 ft².

The area of the triangle with base 10 cm and height 115 cm is A = (1/2) × base × height = (1/2) × 10 cm × 115 cm = 575 cm².

The area of the trapezoid with bases 5 m and 8 m, and height 4 m is A = (1/2) × (base1 + base2) × height = (1/2) × (5 m + 8 m) × 4 m = 26 m².

The area of the triangle with base 3 cm and height 8 cm is A = (1/2) × base × height = (1/2) × 3 cm × 8 cm = 12 cm².

The area of the rectangle with length 1.5 m and width 5 m is A = length × width = 1.5 m × 5 m = 7.5 m².

The area of the trapezoid with bases 6 ft and 3 ft, and height 4 m is A = (1/2) × (base1 + base2) × height = (1/2) × (6 ft + 3 ft) × 4 m = 9 ft × 4 m = 36 ft².

Therefore, the unlock code is: 54-575-26-12-7.5-36.

Rotate point A 180 counterclockwise about the origin to get point A'. -2,-3 coordinate is A'

What is counterclockwise rotation?

Rotations that are counterclockwise (CCW) travel in the opposite direction from how a clock's hands move. Positive numerals are used to indicate these rotations.

Rotation in either a clockwise or anticlockwise direction refers to a change in the electrical activity flowing through the heart in a horizontal plane. Consider the observer as being at the bedside of the sufferer. It is known as anticlockwise rotation if the patient's heart's electrical activity has shifted more to their right side. It is known as clockwise rotation if the patient's heart's electrical activity has shifted more to the left.

Our point A(x,y) rotates 180 degrees anticlockwise around the origin to become A' (-x,-y). Making both x and y negative is all we do as a result.

Dear Mary,

I understand your concerns about the cost of attending college and how it might not be worth it in the end. However, earning a college degree can significantly increase your earning potential and lead to greater job opportunities. In fact, individuals with a bachelor's degree earn an average of $1 million more over their lifetime compared to those with only a high school diploma. Moreover, pursuing a degree in chemical engineering can open doors to highly rewarding and well-paying career paths.

I agree that the published costs of attendance on college websites can be overwhelming, but keep in mind that these figures are often the maximum amount and many students receive financial aid to reduce their expenses. Financial aid comes in many forms, including scholarships, grants, work-study programs, and loans. Scholarships and grants do not have to be repaid, so it's worth exploring those options first. Loans can be daunting, but they can also be manageable if you borrow responsibly and budget accordingly.

It's understandable that you may feel uncertain about whether you qualify for financial aid or not, but it's always worth applying. Many families are surprised to find out that they qualify for aid that they didn't expect. The Free Application for Federal Student Aid (FAFSA) is the form used to determine your eligibility for federal and state financial aid, and it's free to complete. Private institutions may also require additional forms, so make sure to check each college's financial aid website for more information.

As for student loans, there are many repayment plans available, and you can choose one that works best for your budget. If you're having trouble finding a job after graduation, you can apply for deferment or forbearance to temporarily suspend your payments. It's important to have a plan in place for repayment, but it's also important not to let the fear of repayment stop you from pursuing your dreams.

I hope this information helps you make a more informed decision about your college plans. Remember, investing in your education can have long-lasting benefits and lead to a brighter future.

Let's assume the number to be x.

According to the problem statement, the sum of a number and its reciprocal is 2 1/6 or 13/6.

So we can set up the equation:

x + 1/x = 13/6

Multiplying both sides by 6x, we get:

6x^2 + 6 = 13x

Bringing all the terms to one side, we get:

6x^2 - 13x + 6 = 0

We can solve for x using the quadratic formula:

x = [13 ± sqrt(13^2 - 4(6)(6))] / (2*6)

x = [13 ± sqrt(169)] / 12

x = [13 ± 13] / 12

So, x can be either 2/3 or 3/2. Therefore, the number is either 2/3 or 3/2.
