Answer:  No it does not .

Step-by-step explanation:

First use the coordinates of point A and B to write an equation.

A (-3,-2)

B(2,1)

We will need to use these points to find the slope first and by doing that we will find the difference in the y values and divide it by the difference in the x values.

-2-1= -3

-3-2 = -5

-3/-5= 3/5  

The slope is 3/5 and now we need to find the y intercept using the same points. As you can see the equation will have to be in slope intercept form which uses the formula y=mx+b  where m is the slope and b is the y-intercept.

We will plot the first points in and solve for b.

-2=3/5(-3) + b

-2= -9/5 + b  

+9/5  +9/5

b = -1/5  

We will now write the equation  y=3/5x - 1/5   .

Now using the equation try point c to see if it fits the graph.  

Point C is (5,3)  so again plot in the x and y coordinates and solve,

3= 3/5(5) - 1/5

3 = 3 - 1/5

3\(\neq\) 14/5

In this case 3 does not equal 14 over 5 so Point c does not fit the graph

According to the centroid theorem, the distance between the vertex and the midpoint of the sides equals 2/3 of a triangle's centroid.

The center of the object is known as the centroid. The centroid of a triangle is the location where the three medians of the triangle meet. The intersection of all three medians is another way to define it. The middle is a line that joins the midpoint of a side and the contrary vertex of the triangle. The ratio of the distance between the median and the centroid of the triangle is 2: 1. It can be determined by taking the average of all the triangle's vertices' x- and y-coordinate points.

a) It would take Anya approximately 4 years to accumulate $40,000 with an annual interest rate of 12%. b) Anya must earn an annual rate of return of approximately 12.6% to save $40,000 in 3 years.

a) To calculate the number of years it would take Anya to accumulate $40,000, we can use the future value formula for compound interest:

Future Value = Present Value * (1 + interest rate)ⁿ

Where:

Future Value = $40,000

Present Value = $25,000

Interest rate = 12% = 0.12

n = number of years

Substituting the given values into the formula, we have:

$40,000 = $25,000 * (1 + 0.12)ⁿ

Dividing both sides of the equation by $25,000, we get:

(1 + 0.12)ⁿ = 40,000 / 25,000

(1.12)ⁿ = 1.6

To solve for n, we can take the logarithm of both sides of the equation:

n * log(1.12) = log(1.6)

Using a calculator, we find that log(1.12) ≈ 0.0492 and log(1.6) ≈ 0.2041. Therefore:

n * 0.0492 = 0.2041

n = 0.2041 / 0.0492 ≈ 4.15

b) To calculate the required rate of return for Anya to save $40,000 in just 3 years, we can rearrange the future value formula:

Future Value = Present Value * (1 + interest rate)ⁿ

$40,000 = $25,000 * (1 + interest rate)³

Dividing both sides of the equation by $25,000, we have:

(1 + interest rate)³ = 40,000 / 25,000

(1 + interest rate)³ = 1.6

Taking the cube root of both sides of the equation:

1 + interest rate = ∛1.6

Subtracting 1 from both sides, we get:

interest rate = ∛1.6 - 1

Using a calculator, we find that ∛1.6 ≈ 1.126. Therefore:

interest rate = 1.126 - 1 ≈ 0.126

To express the interest rate as a percentage, we multiply by 100:

interest rate = 0.126 * 100 = 12.6%

Using a t-table or statistical software, the critical t-value for a 90% confidence interval with 70 degrees of freedom is approximately 1.667.

What is the confidence interval?

A confidence interval is a range of values that is likely to contain the true value of an unknown population parameter, such as the population mean or population proportion. It is based on a sample from the population and the level of confidence chosen by the researcher.

To find the critical T-value for a 90% confidence interval, we need to determine the degrees of freedom (df) and use a T-table or a T-distribution calculator.

Assuming that the sample size is n = 72, the degrees of freedom for a 90% confidence interval would be:

df = n - 1 = 72 - 1 = 71

Using a T-table, we can find the critical T-value for a two-tailed test at a 90% confidence level with 71 degrees of freedom. The result is approximately 1.667.

Therefore, the critical T-value for this 90% confidence interval is 1.667.

Declan's reasoning does make sense. This is because 3/4 and 1/2 have the same denominator, and 3/4 is a larger fraction than 1/2.

Therefore, it is reasonable to assume that 3/4 is greater than 6/12 because 6/12 simplifies to 1/2. Simplifying fractions means dividing the numerator and denominator by the same number, in this case, 6 is divisible by 2, so we can reduce the fraction to 1/2.

So, Declan is correct in his reasoning that 3/4 is greater than 6/12. It is important to understand the relationship between fractions and their denominators to make such comparisons accurately.

3/4 = 9/12

1/2 = 6/12

6/12 = 6/12

Since 9/12 (which is equivalent to 3/4) is greater than 6/12 (which is equivalent to 1/2), we can say that 3/4 is indeed greater than 6/12.

Therefore, Declan's reasoning is correct.

Answer:

The answer is r\(z^{2r}\)

Step-by-step explanation:

The values of r are determined, the general solution can be written as:

y = c1e^(r1t) + c2e^(r2t)

where c1 and c2 are constants that can be determined using initial conditions or boundary conditions, if given.

To find the general solution of the given differential equation:

42y'' + 11y' - 3y = 0

We can assume a solution of the form y = e^(rt), where r is a constant to be determined.

Differentiating y with respect to t:

y' = re^(rt)

Differentiating y' with respect to t again:

y'' = r^2e^(rt)

Now, substitute these expressions for y, y', and y'' into the original differential equation:

42(r^2e^(rt)) + 11(re^(rt)) - 3(e^(rt)) = 0

Simplify the equation by factoring out e^(rt):

e^(rt)(42r^2 + 11r - 3) = 0

For the equation to hold for all t, the expression in the parentheses must equal zero:

42r^2 + 11r - 3 = 0

This is a quadratic equation that can be solved using factoring, the quadratic formula, or other methods. Solving this equation gives two possible values for r:

r1 = (-11 + √(11^2 - 442(-3))) / (242)

r2 = (-11 - √(11^2 - 442*(-3))) / (2*42)

Simplifying these values will give the exact solutions for r.

Once the values of r are determined, the general solution can be written as:

y = c1e^(r1t) + c2e^(r2t)

where c1 and c2 are constants that can be determined using initial conditions or boundary conditions, if given.

The function f(x) = -2|x - 3| + 2 involves a horizontal shift of 3 units to the right, a vertical reflection, and a downward stretch. Its domain is all real numbers, and its range is all real numbers less than or equal to 2.

The function f(x) = -2|x - 3| + 2 is a transformation of the basic absolute value function f(x) = |x|. Let's analyze the transformations and then graph both functions.Transformations:

1. Shifting: The function f(x) = -2|x - 3| + 2 involves a horizontal shift of the absolute value function f(x) = |x|. The term (x - 3) inside the absolute value causes a shift of 3 units to the right.

2. Reflecting: The negative sign in front of the absolute value function reflects the graph across the x-axis. It causes the function to be reflected vertically.

3. Compressing or stretching: There is no compression or stretching factor present in this particular function.

Graph of the basic function f(x) = |x|:

The graph of the basic function f(x) = |x| is a V-shaped graph that passes through the origin (0, 0). It has symmetry with respect to the y-axis.Graph of the given function f(x) = -2|x - 3| + 2:

To graph the given function, we start with the basic absolute value function f(x) = |x| and apply the transformations: a horizontal shift of 3 units to the right and a vertical reflection. The negative coefficient (-2) affects the amplitude, making the graph steeper.

Domain of f(x) = -2|x - 3| + 2:

The domain of the given function is all real numbers since there are no restrictions on the input values of x.

Range of f(x) = -2|x - 3| + 2:

The range of the given function is the set of all real numbers less than or equal to 2, as the vertical reflection and the coefficient (-2) cause the graph to be reflected and stretched downward.

Note: Without specific constraints on the values of x, the domain and range of the given function follow the typical domain and range of absolute value functions.

Answer:

The area of the piece of paper is 466 cm²

Step-by-step explanation:

First you would want to find the area of the rectangle

39x20=780 cm²

Both semi-circles are the same, so you can just find the area of the whole circle

The diameter is 20 cm so you would use 10 as the radius

A=πr²

A=3.14x10²

A=3.14x100

A=314

Then you have to subtract the area of the circle from the area of the rectangle.
