The volume of blood that passes through the cross-section per unit time is approximately 0.1532 cm^3/s.

Poiseuille's Law describes the flow of fluid through a cylindrical tube. It can be used to calculate the volume of blood that passes through a cross-section per unit time. The formula for Poiseuille's Law is as follows:

Q = (π * ΔP * r^4) / (8 * η * L)

Where:

Q is the volume flow rate,

ΔP is the pressure difference across the tube,

r is the radius of the tube,

η is the viscosity of the fluid, and

L is the length of the tube.

Given information:

Viscosity (η) = 0.0010

Radius (r) = 0.030 cm

Length (L) = 3 cm

Pressure difference (ΔP) = 1000 dynes/square cm

First, we need to convert the radius and length to meters, as the SI unit system is typically used in scientific calculations:

Radius (r) = 0.030 cm = 0.030 * 0.01 m = 0.0003 m

Length (L) = 3 cm = 3 * 0.01 m = 0.03 m

Now, we can calculate the volume flow rate (Q) using Poiseuille's Law:

Q = (π * ΔP * r^4) / (8 * η * L)

= (π * 1000 * (0.0003)^4) / (8 * 0.0010 * 0.03)

= (3.1416 * 1000 * 0.000000000027) / (0.024)

= 0.0036756 / 0.024

≈ 0.1532 cm^3/s

Therefore, the volume of blood that passes through the cross-section per unit time is approximately 0.1532 cm^3/s.

The amount to be remitted when paying the invoices together on December 8 is $2,477.19.

To calculate the amount that must be remitted when paying the invoices together on December 8, we need to consider the available discount periods and the due date.

Let's break down the information provided:

Invoice No. 312 dated November 2 for $923.00

Invoice No. 429 dated November 14 for $784.00

Invoice No. 563 dated November 30 for $873.00

Given the terms 5/10, 2/30, n/60, this means that a 5% discount is offered if payment is made within 10 days, a 2% discount is offered if payment is made within 30 days, and the net amount is due within 60 days.

To calculate the amount to be remitted, we need to consider the applicable discount periods. For payments made on or before December 8, the following discounts apply:

Invoice No. 312: 5% discount if paid within 10 days

Invoice No. 429: 5% discount if paid within 10 days

Invoice No. 563: 2% discount if paid within 30 days

To calculate the remitted amount, we subtract the applicable discount from each invoice amount and sum them up:

Invoice No. 312: $923.00 - (5% of $923.00) = $923.00 - ($46.15) = $876.85

Invoice No. 429: $784.00 - (5% of $784.00) = $784.00 - ($39.20) = $744.80

Invoice No. 563: $873.00 - (2% of $873.00) = $873.00 - ($17.46) = $855.54

Total amount to be remitted = $876.85 + $744.80 + $855.54 = $2,477.19

Therefore, the amount to be remitted when paying the invoices together on December 8 is $2,477.19.

The polynomial in standard form is - x⁶ -2x⁴ + 5x - 4 = 0.

The polynomial expression you provided is indeed valid, and we can write it in standard form by rearranging the terms:

f(x) = f(x) - 2x⁴ - x⁶ - 4 + 5x

f(x) - f(x) = -x⁶ - 2x⁴ + 5x - 4

The term "f(x)" appears on both sides of the equation, so we can subtract it from both sides:

The amplitude of a sine function is the absolute value of the coefficient multiplying the sin(x) term.

In this case, the coefficient is -2. Since the amplitude is always positive, we take the absolute value of -2, which gives us an amplitude of 2.

The period of a sine function is given by the formula 2π/b, where b is the coefficient multiplying the x variable. In our equation, the coefficient is 1 (since sin(x) has an implied coefficient of 1), so the period is 2π/1 = 2π.

The phase shift of a sine function is determined by the value inside the parentheses. In this case, there is no value inside the parentheses, so there is no phase shift. The function remains centered around the origin (x = 0).

The vertical shift of a function is the constant term added or subtracted from the trigonometric function. In this equation, the constant term is -3, which means the graph is shifted downward by 3 units.

10x=15+15

10x=30

divide both sides by 10

10x/10=30/10

x=3

Answer:

Part A: This equation has only one solution.

Part B: The solution to the equation is x = 3.

Step-by-step explanation:

To solve the equation 5(2x - 3) = 15, we can follow these steps:

Part A: Determining the number of solutions

Since this is a linear equation with one variable, it can have either one solution, infinitely many solutions, or no solution.

Part B: Solving the equation

Let's solve the equation step by step:

Distribute the 5 on the left side of the equation:

10x - 15 = 15

Add 15 to both sides of the equation to isolate the variable term:

10x - 15 + 15 = 15 + 15

10x = 30

Divide both sides of the equation by 10 to solve for x:

(10x) / 10 = 30 / 10

x = 3

Therefore, the solution to the equation 5(2x - 3) = 15 is x = 3.

To summarize:

Part A: This equation has only one solution.

Part B: The solution to the equation is x = 3.

A = (14 in. + 6 in.)(6 in.)(1/2)

A = 60 in.²

Answer:

60 in^2

Step-by-step explanation:

solution Given:

Area of the shaded region or trapezoid = Area of Rectangle ABCD - Area of triangle CDE

we have

Area of Rectangle ABCD= length* breadth =BC*AB=14*6=84 in^2

Area of Triangle CDE= 1/2* base*height=1/2*DE*CD=1/2*8*6=24 in ^2

Now

Area of the shaded region or trapezoid = Area of Rectangle ABCD - Area of triangle CDE

=84 in^2-24in^2

=60 in^2

Similarly, we have another way to calculate the area of the trapezoid;

Area = 1/2*h*(side1*side2)

=1/2*AB*(AE+BC)

=1/2*6*(6+14)

=60 in^2

This means that approximately 51.57% of the students would have scores between 60 and 75.

The problem is asking for the percentage of students that would have scores between 60 and 75 in a normally distributed test with a mean score of 70 and a standard deviation of 15.

To solve the problem, first we need to standardize the scores by using the formula:

z = (x - μ) / σ where z = the standardized score x = the raw score μ = the mean score σ = the standard deviation Then,

we can find the area between the z-scores corresponding to 60 and 75 using a standard normal distribution table or calculator.

The area represents the percentage of students who scored between 60 and 75.

To find the z-score corresponding to 60:x = 60μ = 70σ = 15z = (60 - 70) / 15 = -0.67

To find the z-score corresponding to 75:x = 75μ = 70σ = 15z = (75 - 70) / 15 = 0.33

Now, we can find the area between -0.67 and 0.33 using a standard normal distribution table or calculator.Using a calculator, we can use the normalcdf function to find the area:normalcdf(-0.67, 0.33) = 0.5157

Step-by-step explanation:

To divide the polynomial (9x^3 - 6x^2 + 15x) by the monomial 3x^2, we can write it as:

(9x^3 - 6x^2 + 15x) ÷ (3x^2)

To simplify the division, we divide each term of the polynomial by 3x^2:

(9x^3 ÷ 3x^2) - (6x^2 ÷ 3x^2) + (15x ÷ 3x^2)

To divide monomials with the same base, we subtract the exponents. So:

9x^3 ÷ 3x^2 = 9/3 * (x^3/x^2) = 3x^(3-2) = 3x

(-6x^2) ÷ (3x^2) = -6/3 * (x^2/x^2) = -2

15x ÷ 3x^2 = 15/3 * (x/x^2) = 5/x

Putting it all together, we have:

(9x^3 - 6x^2 + 15x) ÷ (3x^2) = 3x - 2 + 5/x

Therefore, the division of (9x^3 - 6x^2 + 15x) by 3x^2 is 3x - 2 + 5/x.

Answer:

Brenda will be able to afford the $20,000 car after 10 years.

Step-by-step explanation:

To determine whether Brenda will be able to afford a $20,000 car after 10 years, we need to calculate the future value of her investment with an interest rate of 4.5%.

The formula for calculating the future value of an investment is:

FV = PV * (1 + r)^n

Where:

FV = Future Value

PV = Present Value (initial investment)

r = Interest rate

n = Number of periods

In this case, Brenda's initial investment (PV) is $15,000, the interest rate (r) is 4.5% (or 0.045 as a decimal), and the number of periods (n) is 10 years.

Let's calculate the future value of Brenda's investment:

FV = $15,000 * (1 + 0.045)^10

FV = $15,000 * (1.045)^10

FV ≈ $22,292.26

After 10 years, Brenda's investment will grow to approximately $22,292.26.

Since the future value of her investment is greater than the cost of the car ($20,000), Brenda will be able to afford the $20,000 car after 10 years.
