Find the number of arrangements that can be made by taking 4 letters from the letters of the word addressee.

The worker worked 38 + 5 = 43 hours that week.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Let's break this problem down into two parts.

Part 1: Calculating the base pay for the 38 hours worked

The worker earned #80 per hour for a 38-hour week, so the base pay for those 38 hours would be:

Base pay = #80/hour x 38 hours = #3040

Part 2: Calculating the overtime pay for the additional hours worked

To find out how many hours were worked beyond the 38-hour week, we can use the fact that the total pay for the week was #3640. We know that the base pay for 38 hours was #3040, so the remaining #600 must be the overtime pay.

Since the company pays overtime at a time and a half, we can use this to find out how many hours were worked beyond the 38-hour week:

Overtime pay = (#80/hour x 1.5) x (number of overtime hours)

We can rearrange this equation to solve for the number of overtime hours:

Number of overtime hours = Overtime pay / (#80/hour x 1.5)

Number of overtime hours = #600 / (#80/hour x 1.5) = 5

Therefore, the worker worked 38 + 5 = 43 hours that week.

Answer: To find out how much commission Yamilet will receive for selling an $8,125 ring, we need to multiply the price of the ring by her commission rate, which is 12% or 0.12 in decimal form.

Commission = Price of ring x Commission rate

Commission = $8,125 x 0.12

Commission = $975

Therefore, Yamilet will receive a commission of $975 for selling an $8,125 ring.

Step-by-step explanation:

As a result, 7 is the number of w that solves the problem.

In mathematics, a denominator is the lowest integer in a proportion that indicates how many equal portions are split into a whole. It is a fraction's division. In this case, the fraction is 4, so there are four components overall.

To solve for w in the equation (W+3)/4 = (W-2)/2, we can start by cross-multiplying to eliminate the denominators:

2(W+3) = 4(W-2)

Expanding the brackets:

2W + 6 = 4W - 8

Simplifying:

2W = 14

W = 7

Therefore, the value of w that satisfies the equation is 7.

The present value of the annuity is $189,468.24 if the initial payment is $1,000 and the monthly interest rate is 0.3333%.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

To solve this problem, we need to first find the monthly interest rate since the payments are made monthly. The monthly interest rate can be found by dividing the annual interest rate by 12:

i = 4% / 12 = 0.3333% per month

Next, we need to find the present value of the annuity. We can use the formula for the present value of an annuity-immediate:

[tex]PV = P * (1 - (1 + i)^{-n}) / i[/tex]

where PV is the present value, P is the monthly payment, i is the monthly interest rate, and n is the number of payments.

The first year, the payments are level, so we can use the formula with n = 12 to find the present value of the payments for the first year:

[tex]PV1 = 1000 * (1 - (1 + 0.003333)^{-12}) / 0.003333 = \$11,887.87[/tex]

For the second year, the payments increase by 2%, so the monthly payment for the second year will be:

P2 = 1000 * 1.02 = $1,020

We can then use the formula again with n = 12 to find the present value of the payments for the second year:

[tex]PV2 = 1020 * (1 - (1 + 0.003333)^{-12}) / 0.003333 = \$12,061.92[/tex]

We can continue this process for the remaining 18 years, increasing the payment by 2% each year. The total present value of the annuity is the sum of the present values of each year's payments:

PV = PV1 + PV2 + ... + PV20 = $189,468.24

Therefore, the present value of the annuity is $189,468.24 if the initial payment is $1,000 and the monthly interest rate is 0.3333%.

The closest option to the cone area is 923.2 m². 

A cone is a shape formed from a series of line segments or lines that connect a common point, called a vertex or vertex, to all points on the base of a circle that do not contain vertices. The distance from the apex of the cone to the base is called the height of the cone.

To solve this problem, we need to find the surface of the cone. Formula for the surface area of cone:

A = [tex]\pi[/tex]r² + [tex]\pi[/tex]rℓ

where r is the radius of the base, ℓ is the height of the depression, and π is a constant of approximately 3.14159.

First, we find the radius of the base. Since the bottom line of the cone is listed as 18 feet and we know the radius is 14 feet, we can use the Pythagorean theorem to find the height of the cone.

h² = ℓ² - r²

h² = 19.3² - 14²

h ≈ 11.48 feet

Now we can compute the surface.

A = [tex]\pi[/tex](14)² + [tex]\pi[/tex](14)(19.3)

A ≈ 923.2 square feet

So the closest option to the cone area is 923.2 m².

The number of students who scored more than 70 but less than 80 is zero.

A stem-and-leaf diagram is a quantitative analysis of a collection of data points that are separated into a "stem" (the first digit of the number) and a "leaf" (the remainder of the number) (the last digit of the number).

To find the number of students who scored more than 70 but less than 80, we need to look at the stem-and-leaf plot and count the number of leaves that fall within this range.

Stem 7 has a leaf of 6, which represents a score of 76. Therefore, at least one student scored between 70 and 76.

The stem 8 has leaves of 2, 5, and 8, which represent scores of 82, 85, and 88, respectively. Therefore, no students scored between 76 and 80.

Therefore, the number of students who scored more than 70 but less than 80 is zero.

The answer is m = 0.

a. The equation of the tangent plane is z = 1 + x.

b. The point (4/3, 8/3, 5) lies on both the plane T(0,1) and the line l.

c. The other points on the graph of f(x) whose tangent plane contains the line l are (-9/8, -1/2, -21/8) and (-25/32, -3/4, -47/32)

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

(a) The partial derivatives of f(x) at this point:

∂f/∂x = 2x + y²

∂f/∂y = x² + 2xy

Evaluating these at (0,1), we get:

∂f/∂x(0,1) = 1

∂f/∂y(0,1) = 0

So the equation of the tangent plane is:

z = f(0,1) + ∂f/∂x(0,1)(x-0) + ∂f/∂y(0,1)(y-1)

z = 1 + x

(b)

The plane T(0,1) contains the line l:

2x = y = (z+3)/2

Substituting y = 2x and z = 2y-3, we get:

z = 2(2x) - 3 = 4x - 3

So any point on the line l can be written as (x, 2x, 4x-3).

Substituting these values into the equation of the plane, we get:

4x-3 = 1 + x

3x = 4

So x = 4/3, y = 8/3, and z = 5.

Therefore, the point (4/3, 8/3, 5) lies on both the plane T(0,1) and the line l.

(c) To find all other points on the graph of f whose tangent plane contains the line l, we need to find the intersection of the graph of f with the plane T(0,1) + λ(2,0,1), where λ is a scalar. This gives us the system of equations:

x² + y²xy = 1 + x + 2λ

2x + y² = 0

y - 1 = λ

Solving for x and y in terms of λ, we get:

y = λ + 1

x = -(y²)/2 = -(λ+1)²/2

Substituting these values into the first equation, we get:

(λ+1)² + (λ+1)²(-(λ+1)²/2) = 1 - (λ+1)²/2 + 2λ

Simplifying and solving for λ, we get:

λ = -1/2, -1/4

Therefore, the other points on the graph of f(x) whose tangent plane contains the line l are:

(-9/8, -1/2, -21/8) and (-25/32, -3/4, -47/32)

Mark needs a score of 2 on the 5th test to pass the course

Let X be the score Mark needs to get on the fifth test to pass the course.

To find X, we can use the formula for the mean of five numbers:

(mean of 5 numbers) = (sum of the 5 numbers) / 5

We know that Mark needs a mean score of 10 to pass, so:

10 = (total score on all 5 tests) / 5

Multiplying both sides by 5, we get:

50 = total score on all 5 tests

We also know that Mark's mean score on the first four tests is 12, so:

(mean score on the first four tests) = (total score on the first four tests) / 4

12 = (total score on the first four tests) / 4

total score on the first four tests = 48

To pass the course with a mean score of 10, Mark needs a total score of 50, and he has already scored 48 on the first four tests. Therefore, he needs to score:

Step-by-step explanation:

To find the inverse of the exponential function y = (3/2)^x, we need to interchange the roles of x and y, and then solve for y.

So, starting with y = (3/2)^x, we can write:

x = (3/2)^y

To solve for y, we can take the logarithm of both sides with base 3/2:

log(3/2) x = y

Therefore, the inverse of the exponential function y = (3/2)^x is:

y = log(3/2) x

or in exponential form:

y = (log base 3/2) x

This function is the logarithmic function with base 3/2.
