If your rate of pay is $36 per hour and you bill by the quarter hour, you would bill $162 for 4 hours and 30 minutes project.

Based on the given information, your rate of pay is $36 per hour, and you bill by the quarter hour. You spent 4 hours and 30 minutes on a client project.

To calculate the bill, first convert the 30 minutes into quarter hours: 30 minutes = 2 quarter hours. In total, you worked for 4 hours and 2 quarter hours (18 quarter hours).

Now, multiply your rate of pay ($36) by the number of quarter hours (18) and divide by 4 to account for the quarter hour billing: ($36 * 18) / 4 = $162. Therefore, you would bill the client $162 for the project.

Answer:

Step-by-step explanation:

The expression +3(5-3) can be simplified using the order of operations (PEMDAS) as follows: first, we need to perform the exponentiation operation, which gives us 125.

Then, we need to perform the operation inside the parentheses, which gives us 6. Finally, we multiply 3 by 6, giving us 18. Therefore, the simplified expression is 125 + 18 = 143.

To further explain this solution, we use the order of operations, which is a set of rules that dictate the order in which operations must be performed when evaluating an expression. The acronym PEMDAS stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction, which represents the order of operations from left to right.

In this expression, we first need to evaluate the exponentiation operation, which is 5 to the third power. This gives us 125. Next, we need to perform the operation inside the parentheses, which is 5-3. This gives us 2. We then multiply 3 by 2, which gives us 6. Finally, we add 125 and 6, giving us 131.

It is important to follow the order of operations when simplifying an expression to ensure that we obtain the correct result. By using PEMDAS, we can systematically simplify an expression step-by-step, avoiding any potential errors and obtaining a clear and concise solution.

The area inside the square and outside the circle is 0.86 square units.

To find the area inside the square and outside the circle, we need to first find the area of the square and the area of the circle.

Let's assume that the square has sides of length 2 units, which means its area is:

Area of square = side^2 = 2^2 = 4 square units

Now, let's assume that the circle has a radius of 1 unit, which means its area is:

Area of circle = pi * radius^2 = 3.14 * 1^2 = 3.14 square units

To find the area inside the square and outside the circle, we need to subtract the area of the circle from the area of the square:

Area inside square and outside circle = Area of square - Area of circle

                                     = 4 - 3.14

When the diameter of the balloon is 50 cm, the radius of the balloon is increasing at a rate of approximately 0.0254 cm/s

We are given that the volume of a spherical balloon is increasing at a rate of 100 cm³/s. We need to find how fast the radius of the balloon is increasing when the diameter is 50 cm.

Let's first find the expression for the volume of the balloon in terms of its radius.

V = 4/3 πr³

Differentiating with respect to time (t), we get:

dV/dt = 4πr² (dr/dt)

We are given that dV/dt = 100 cm³/s. When the diameter of the balloon is 50 cm, the radius is 25 cm.

Substituting these values, we get:

100 = 4π(25)² (dr/dt)

Simplifying, we get:

dr/dt = 100 / (4π(25)²)

dr/dt ≈ 0.0254 cm/s

Therefore, when the diameter of the balloon is 50 cm, the radius of the balloon is increasing at a rate of approximately 0.0254 cm/s

MN² = (6.7 feet)² - (1.7 feet)²

MN² = 44.56 feet²

MN = 6.67 feet

Now, we can use the sine function to find the measure of ∠N:

sin(N) = MN/NO

sin(N) = 6.67 feet / 6.7 feet

To determine the convergence of the integral 4(1-z)/(2^2 +1)² dz from 0 to infinity, we can use the comparison test.

First, note that (1-z) is bounded between 0 and 1, so we can compare it to the integral of 4/(2² +1)² dz from 0 to infinity, which is convergent since it is a constant times the convergent p-series with p=2.

Therefore, by the comparison test, the original integral is also convergent. To evaluate it, we can use partial fractions:

4(1-z)/(2² +1)^2 = A/(2+i)² + B/(2-i)²

Solving for A and B, we get A = (1+i)/5 and B = (1-i)/5.

Then, the integral becomes:

∫ 4(1-z)/(2² +1)² dz = A ∫ 1/(2+i)² dz + B ∫ 1/(2-i)² dz

= (1+i)/5 [-1/(2+i)] + (1-i)/5 [-1/(2-i)] from 0 to infinity

= [(1+i)(2-i) - (1-i)(2+i)]/25(2² +1)

= 0

Therefore, the integral is convergent and evaluates to 0.

To determine if an integral is convergent or divergent, you need to look at its limits and the function you are integrating. Convergent means that the integral has a finite value, while divergent means the integral does not have a finite value.

For example, if you have an integral like this:

∫(f(x) dx) from a to b,

you need to evaluate the limits 'a' and 'b' and the function 'f(x)'. If 'a' or 'b' is infinity (∞) or the function 'f(x)' behaves such that it leads to an infinite value for the integral, it is divergent. Otherwise, it is convergent.

Part B: The greatest number of music stands the club can buy is 6, and the greatest number of songs the club can buy is 3.

Part A:

The cost of x music stands is 15x dollars, and the cost of y songs is 350y dollars. The total cost cannot exceed $2,100, so we can write the following equation:

15x + 350y = 2100

Therefore, the equation that describes the amount of music stands and songs that the band club can purchase is 15x + 350y = 2100.

Part B:

To find the greatest number of each item the club can buy, we can use the given equation and look for integer solutions for x and y that satisfy the equation.

We can rearrange the equation to solve for y:

y = (2100 - 15x) / 350

To get integer solutions for y, we need 2100 - 15x to be divisible by 350. The largest multiple of 350 that is less than or equal to 2100 is 6*350 = 2100. So, we can try x = 0, 1, 2, 3, ..., 6 and see which values give integer solutions for y.

When x = 0, y = 6, which is an integer solution.

When x = 1, y = 5, which is not an integer solution.

When x = 2, y = 4, which is not an integer solution.

When x = 3, y = 3, which is an integer solution.

When x = 4, y = 2, which is not an integer solution.

When x = 5, y = 1, which is not an integer solution.

When x = 6, y = 0, which is an integer solution.

The area of the shaded region of the circle is A = 57,918.5 feet²

Given data ,

First, we need to find the area of the quarter circle:

Area of quarter circle = (1/4)  π ( r )²

= (1/4)  π ( 290 )²

= 66,018.5 feet²

Next, we need to find the area of the square:

Area of square = side²

= 90²

= 8,100 feet²

Now, we can find the area of the shaded section by subtracting the area of the square from the area of the quarter circle:

Area of shaded section = Area of quarter circle - Area of square

= 66,018.5 feet² - 8,100 feet²

= 57,918.5 feet²

Hence , the area of the shaded section of the field is 57,918.5 feet²
