The equation of the line given by the coordinates (-8, 3) and (-6, 0) is 2y = -3x -18.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Hence, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = (y2 - y1) / (x2 - x1)

The coordinates of the points are:

(-8, 3) and (-6, 0)

The slope of the line is given as:

m = (y2 - y1) / (x2 - x1)

Substituting the coordinates we have:

m = (0 - 3)/ (-6 + 8)

m = -3/2

Using the point slope form:

y - y1 = m (x - x1)

Substituting the values of slope and coordinates we have:

y - 3 = -3/2(x + 8)

2(y - 3) = -3(x + 8)

2y - 6 = -3x -24

2y = -3x -18

Hence, the equation of the line given by the coordinates (-8, 3) and (-6, 0) is 2y = -3x -18.

Using the formula of simple interest, the time it will take to accumulate to $3200 at a rate of 4.5% is 71.35 years

Simple interest is a method of calculating the interest charge on a loan or deposit. It is based on the principle of earning interest only on the initial amount (principal) that was borrowed or deposited.

The formula for simple interest is:

I = P * r * t

where:

I is the interest amount

P is the principal amount

r is the interest rate (expressed as a decimal)

t is the time period (in years)

Substituting the values into the formula;

A = P(1 + rt)

3200 = 760(1 + 0.045(t))

3200 = 760 + 34.2t

34.2t = 3200 - 760

34.2t = 2440

Answer: See the attached image below for the proof table.

Explanation:

We start with what we're given. Simply repeat the given information word for word. This is statement 1 of the proof.

Statement 2 mentions AB is parallel to CD. This is valid due to the definition of a parallelogram. The name means "two sets of opposite parallel sides. Statement 3 is a similar situation.

Statement 4 relies on statement 2. The red angles in the diagram are congruent alternate interior angles. They are only congruent because of AB parallel to CD.

Statement 5 relies on statement 3 for similar reasoning as the previous paragraph. Focus on the blue angles.

Statement 6 is hopefully self explanatory so there's not much for me to mention here.

Statement 7 has us connect statements 4, 5, and 6 to prove triangle ADB is congruent to triangle CBD. We use the ASA (angle side angle) theorem here.

Statements 8 and 9 finish up the proof. CPCTC stands for "Corresponding parts of congruent triangles are congruent". If two triangles are congruent, then their corresponding pieces must be congruent as well. It would be like saying two houses are identical if and only if their front doors are identical.

The area of the equilateral triangle with side length 10 cm is 25 cm².

What is triangle ?

Triangle can be defined in which it consists of three sides , three angles and sum of three angles is always 180 degrees.

To find the area of an equilateral triangle, we need to find the height first. The height of an equilateral triangle is equal to the length of the perpendicular line from the center of the triangle to one of its sides.

To find the height, we can divide the equilateral triangle into two 30-60-90 triangles. The height is equal to half of the hypotenuse of one of these triangles, which can be calculated as:

10 cm / 2 = 5 cm

Now that we have the height, we can find the area of the equilateral triangle as follows:

Area = ½ * base * height

Area = ½ * 10 cm * 5 cm

Area = 25 cm²

Hence, The area of the equilateral triangle with side length 10 cm is 25 cm².

Answer:

Marianna will have $19,700 in her annuity after 6 years.

Step-by-step explanation:

To find the amount of money in the annuity after 6 years, we need to calculate the compound interest earned over that time period.

First, let's find the interest rate per quarter: 8% annual interest divided by 4 quarters per year = 2% interest per quarter.

Next, we'll calculate the number of quarters that the money is invested: 6 years x 4 quarters per year = 24 quarters.

Now we can use the formula for compound interest to find the total amount of money in the annuity after 6 years:

A = P * (1 + r/n)^(nt)

Where:

A = final amount

P = initial investment ($10,000 in this case)

r = interest rate per quarter (2% or 0.02)

n = number of times the interest is compounded in a year (4)

t = number of years invested (6)

Plugging in the values:

A = $10,000 * (1 + 0.02)^(24)

A = $10,000 * 1.96634438

A = $19,663.44

Rounding to the nearest hundred dollars: $19,700

So, Marianna will have $19,700 in her annuity after 6 years.

The exact perimeter of the segment is 54.13 inches, and the exact area of the segment is 301.44 square inches.

What is perimeter and area enclosed in circle?

A circle is also defined by two properties: area and perimeter. The formulas for both the measures of the circle are given by; Area of a circle = πr². The perimeter of a circle = 2πr.

Let's call the center of the circle O and the endpoint of the arc A. Let's also call the endpoint of the chord that defines the segment B. Then we have an isosceles triangle OAB, where OA = OB = 24 inches.

1) The perimeter of the segment is equal to the length of the arc plus the length of the chord. To find the length of the arc, we can use the formula:

Arc length = (Ф / 360) * 2πr,

where Ф is the measure of the angle in degrees, r is the radius (which is 24 inches in this case), and π is pi.

In this case, the measure of the angle is 60°, so the length of the arc is:

Arc length = (60 / 360) * 2π * 24 inches

Arc length  = (1/6) * 2π * 24 inches

Arc length  = 4π inches

To find the length of the chord, we can use the formula:

Chord length = 2r * sin(Ф/2), where r is the radius and Ф is the measure of the angle in radians.

First, we need to convert the angle measure from degrees to radians:

60° = 60 * (π / 180) radians = π / 3 radians

Now, we can find the length of the chord:

Chord length = 2 * 24 * sin(π / 6)

Chord length = 24 * 2 * sin(π / 6)

Chord length = 24 * √3 inches

Finally, we can add the length of the arc and the chord to find the perimeter:

Perimeter = 4π + 24 * √3

Perimeter = 4π+41.57

Perimeter = 54.13 inches

2) To find the area of the segment, we can use the formula:

Area = (Ф/ 360) * πr², where Ф is the measure of the angle in degrees and r is the radius.

In this case, the measure of the angle is 60°, so the area of the segment is:

Area = (60 / 360) * π * 24² square inches

Area = (1/6) * π * 576 square inches

Area = 96π square inches

Area = 301.44 square inches

So, The exact perimeter of the segment is 54.13 inches, and the exact area of the segment is301.44 square inches.

Given that, simplify the following:

2/3 x 2/5

4/2 x 6/3

2/4 x 3/6

2/3 x 6/3

For the expression 2/3 x 2/5:

To multiply fractions, we multiply the numerators together and the denominators together.

So, (2 x 2)/(3 x 5) = 4/15.

For the expression 4/2 x 6/3:

Again, we multiply the numerators together and the denominators together.

Thus, (4 x 6)/(2 x 3) = 24/6 = 4.

For the expression 2/4 x 3/6:

Following the same process, we multiply the numerators and denominators.

Therefore, (2 x 3)/(4 x 6) = 6/24 = 1/4.

Lastly, for the expression 2/3 x 6/3:

Similarly, we multiply the numerators and denominators together.

Hence, (2 x 6)/(3 x 3) = 12/9 = 4/3.

Therefore, the result of fraction multiplication are:

2/3 x 2/5 = 4/15

4/2 x 6/3 = 4
