What do you mean by composite figure?

A compound shape or figure is a two-dimensional figure made up of basic two-dimensional shapes such as triangles, rectangles, circles, and semicircles.

To find the perimeter of a compound 2D shape, add the lengths of the sides. Find individual regions for each part of the compound shape. The area of ​​a composite shape is the sum of its individual areas.

Let the given composite figure be divided into four rectangles A,B,C and D having dimension 3 and 4

Area of rectangle A = 3 × 4 = 12

Area of rectangle A = area of rectangle B = area of rectangle C = area of rectangle D = 12 square feet.

Total area = Area of rectangle A + area of rectangle B + area of rectangle C + area of rectangle D = 12 + 12 + 12 + 12 =48 square feet

The amount borrowed is $66,000, the annual interest rate is 4 %, the number of payments per year is 12, the loan term is 20 years, and the payment amount is $10668.39.

Compound interest is applicable when there will be a change in the principle amount after the given time period.

For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.

The total amount paid is,

A = 4800[1 + 0.04/12]^(12 x 20)

A = $10668.39

Hence "The amount borrowed is $66,000, the annual interest rate is 4 %, the number of payments per year is 12, the loan term is 20 years, and the payment amount is $10668.39".

Answer:

n = 45

m = 135

Step-by-step explanation:

The sum of the interior angles of a triangle is 180

180 - 55 - 80 = 45

m = the sum of 55 + 80

n= 45°;

m= 135.

The sum of all interior angles of a triangle must equa 360°. Hence, the value of n is given by the following expression:

[tex]n+55+80=180\\ \\n=180-55-80\\\\ n=45[/tex]

Since "m" and "n" are opposites angles and, since there's a straight line adjacent to them, the sum of m and n should equal 180 (check the attached image). Find m with the following expression:

[tex]45+m=180\\ \\m=180-45\\ \\m=135.[/tex]

The roots of a quadratic function are the values of x that make the function is 0. These roots can be found by solving the equation f(x) is 0.

A quadratic function is a type of mathematical function that can be written in the form f(x) = ax^2 + bx + c, where a, b, and c are constants and a is not equal to 0. This type of function is called a quadratic function because the highest power of x in the function is 2.

The graph of a quadratic function is a parabola, which is a U-shaped curve. The shape of the parabola is determined by the value of the constant a. If a is positive, the parabola opens upwards and if a is negative, the parabola opens downwards.

The roots of a quadratic function are the values of x that make the function equal to 0. These roots can be found by solving the equation f(x) = 0. To solve this equation, we can use the quadratic formula, which is:

Using Associative property for the given expression.

We get:

[tex]\rule[225]{225}{2}[/tex]

The answer to this question is = 12 + n is the expression not equivalent to 8 + (n - 4)

Let us consider any random value of n for example let us take the value of n = 5

As per the original equation given in question 8 + (n - 4) if we substitute the value of n = 5

= 8+ (5 - 4)

= 8+1

= 9

Now we will be substituting the value of n in all the answer options-

Option 1- (8 - 4) + n

= (8 - 4) + 5

= 4 + 5

= 9

Therefore, this answer matches the original equation so this is not the correct option

Option 2- (8 + 4) - n

= (8 + 4) - 5

= 13 - 5

= 9

Therefore, this answer matches the original equation so this is not the correct option

Option 3- n+4

Compound interest is that the interest on savings calculated on each the initial principal and therefore the accumulated interest from previous periods.

Main body:

Given :

Total amount = $1800

Compounded monthly,

so formula becomes,

Total amount = amount (1+r/1200)^12t

T = A[tex](1+r/1200)^{12t[/tex]

1800 = 900 (1+6/1200)^12t

2 = (1+1/200)^12t

2 = 1.005^12t

taking log on both sides

log 2 = 12t *log 1.005

0.3/0.002 = 12t

t = 12.5 years

The rectangular coordinates are (-3.825,-1.169).

In a rectangular coordinate system, we were plotting points based on an ordered pair of (x, y). In the polar coordinate system, the ordered pair will now be (r, θ). The ordered pair specifies a point’s location based on the value of r and the angle, θ, from the polar axis.

The value of r can be positive, negative, or zero. The sign of r is very important in locating the exact position of the point. The absolute value of r, |r|, is the distance between the point and the pole.

1. If r is positive (r > 0) then the point lies on the terminal side of θ

2. If r is negative (r < 0) then the point lies on the ray opposite of the terminal side of θ

3. If r is zero (r = 0) then the point lies at the pole regardless of θ

Given,

Answer:

Step-by-step explanation:

a. The music stalls collected Ks 3000.

b. The game stalls collected Ks 4800, which is a fraction of the total amount of money collected. To find the fraction, we can divide the amount collected by the game stalls by the total amount collected by all the stalls:

$\frac{Ks 4800}{Ks 3000 + Ks 4800 + Ks 3000} = \frac{Ks 4800}{Ks 10800} = \frac{2}{9}$

Therefore, the game stalls collected $\frac{2}{9}$ of the total amount of money.

c. The food stalls collected Ks 4800, which is a percentage of the total amount of money collected. To find the percentage, we can divide the amount collected by the food stalls by the total amount collected by all the stalls and multiply by 100%:

$\frac{Ks 4800}{Ks 3000 + Ks 4800 + Ks 3000} \times 100% = \frac{Ks 4800}{Ks 10800} \times 100% = 44.44%$

Therefore, the food stalls collected 44.44% of the total amount of money.

d. The handicraft stalls collected Ks 3000, and the music stalls collected Ks 3000. The ratio of the money collected by the handicraft stalls to the money collected by the music stalls is therefore 1:1. We can write this ratio as $\frac{1}{1} = 1$, or simply as 1.

The amount A in an account to the nearest cent, the amount A in the account after 10 years is $30,441.65.

Generally, To find the amount A in the account after 10 years, we can use the formula for continuous compound interest:

A(t) = A(0) * e^(rt)

where A(t) is the amount in the account after t years, A(0) is the initial amount in the account, r is the interest rate, and t is the number of years.

In this case, we know that A(0) = $15,000, A(8) = $22,377.37, and t = 10 years. We can rearrange the formula to solve for r:

r = (1/t) * ln(A(t)/A(0))

Substituting the known values, we get:

r = (1/10) * ln(22377.37/15000)

Solving this equation, we get r = 0.0658082.

Now that we have the value of r, we can use the formula for continuous compound interest to find the amount A in the account after 10 years:

A(10) = 15000 * e^(0.0658082 * 10)

Solving this equation, we get A(10) = $30,441.65.

All points in a plane that are at a specific distance from a specific point, the center, form a circle.
Formula for the first circle: x²+ y² = 9

Formula for the second circle:

center is (0, 7.5) and the radius is 15/2, so

x² + (y - 7.5)² = (7.5)²

Combining these yields:

9 - y² + (y - 7.5)² = (7.5)²

9 - y² + y² - 15y + (7.5)² = 7.5²

9 - 15y = 0

y = 9/15 = 3/5

∴ y = 0.6

x² + y² = 9 = x² + (3/5)²

x² = 9 - (9/25)

x² = [(225 - 9)/25] = 216/25

∴ x = 2.9394

r = √(x² + y²) =

r = √[( 216/25) + (9/25)]

r = √(225/25) = 15/5

To find the coordinates of a point on a circle with radius 10 corresponding to an angle of 325 degrees, you can use the following formula:

(x, y) = (r * cos(θ), r * sin(θ))

where (x, y) are the coordinates of the point, r is the radius of the circle, and θ is the angle in radians.

To convert the angle from degrees to radians, you can use the following formula:

θ (radians) = θ (degrees) * (π / 180)

Substituting the values into the formula and converting the angle to radians, you get:

(x, y) = (10 * cos(325 * (π / 180)), 10 * sin(325 * (π / 180)))

= (-5.5, 9.5)

Therefore, the coordinates of the point on the circle with radius 10 corresponding to an angle of 325 degrees are (-5.5, 9.5).
