The area of the triangular section is 12 square units and the area of the entire figure is 60 square units.

We know that the Area of triangle is defined as the product of its height to its base.

Area of triangle =  height × base

From the figure, we can see that Height is = 4 units and the base is = 6 units,

So, the area of the triangular section is = 1/2 × base × height,

⇒ (1/2) × 6 × 4

⇒ 12 square units

The entire figure consists of two figure , one is a rectangle and the other part is a triangle,

So, the area of the entire figure is = Area of rectangle + area of triangle

⇒ 4×12 + 12

⇒ 48 + 12

⇒ 60 square units

Therefore, the area of the entire figure is 60 square units.

x=18/6=3

The value of x is 30 degrees.

A right-angled triangle is a type of triangle that has one angle that measures exactly 90 degrees (a right angle). This angle is formed by the intersection of the two sides of the triangle that are perpendicular to each other, which are called the legs or the adjacent and opposite sides. The side opposite the right angle is called the hypotenuse, and it is always the longest side in the triangle. The other two sides are usually labeled as a and b, and are called the legs or the adjacent and opposite sides depending on which angle is being considered. The Pythagorean theorem, which states that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse, is one of the fundamental properties of right-angled triangles. Right-angled triangles have numerous practical applications in geometry, trigonometry, physics, and engineering.

We can use the trigonometric ratio of sine to find the angle x.

sin(x) = opposite/hypotenuse = PQ/PR = 48/96 = 1/2

Taking the inverse sine of both sides, we get:

x = sin^(-1)(1/2)

Using a calculator, we get:

x ≈ 30 degrees

Therefore, the value of x is 30 degrees.

Polynomial multiplication is the process of multiplying two polynomials together to get a new polynomial that represents the product of the two original polynomials.

It should be noted that to multiply two polynomials, you need to perform a distributive operation. You take each term of the first polynomial and multiply it by each term of the second polynomial. Then, you add all the resulting terms together to get the final polynomial.

For example, let's say you want to multiply the polynomials (x + 2) and (x - 3).

First, you multiply the x term in the first polynomial by the x term in the second polynomial:

(x) * (x) = x²

Next, you multiply the x term in the first polynomial by the -3 term in the second polynomial:

(x) * (-3) = -3x

Then, you multiply the 2 term in the first polynomial by the x term in the second polynomial:

(2) * (x) = 2x

Finally, you multiply the 2 term in the first polynomial by the -3 term in the second polynomial:

(2) * (-3) = -6

Now, you add up all the resulting terms to get the final polynomial:

x² - x - 6

Therefore, the product of (x + 2) and (x - 3) is x² - x - 6.

The workman's hourly rate of pay for a 40-hours week is 380.

Hourly rate of pay = Total pay ÷ Total hours worked

Hourly rate of pay = 15, 200 ÷ 40 = 380

Therefore, the workman is paid 380 per hour for a 40-hours week. To calculate the hourly rate of pay, the total pay is divided by the total hours worked. In this case, the total pay is 15, 200 and the total hours worked is 40, so when we divide 15, 200 by 40, we get 380. This is the hourly rate of pay for the workman for the 40-hours week.

The given function of the cost represents exponential growth.

A form of growth known as exponential growth occurs when the rate of expansion is proportionate to the present value. This implies that the rate of growth increases as the present quantity increases. An exponential function, such as the one in this question (y = abx, where an is the starting value, b is the growth factor, and x is the number of time periods), may be used to describe exponential growth. In natural and social processes, such as population expansion, economic growth, and the spread of illnesses, exponential growth is frequently seen. Yet, there are always resource constraints and other factors that will ultimately reduce or stop the expansion, therefore exponential growth cannot last eternally.

The given function is y=100(1. 05)^x.

To find cost for certain year we substitute different value of x.

From the function we observe that as the value of x increases the function increases continuously.

Hence, the given function of the cost represents exponential growth.

Step-by-step explanation:

Use the triangle bisector theorem:

"The angle bisector of a triangle divides the opposite side into two parts proportional to the other two sides of the triangle."

so 12 is to 16  as   x is to 20

12/ 16 = x/20

20 * 12/16 = x = 15 units

Answer:

x = 15

Step-by-step explanation:

the segment inside the triangle is an angle bisector and divides the side opposite the angle into segments that are proportional to the other two sides , that is

[tex]\frac{12}{16}[/tex] = [tex]\frac{x}{20}[/tex] ( cross- multiply )

16x = 12 × 20 = 240 ( divide both sides by 16 )

As a result, it takes around 0.25 minutes for the oven to reach 300°F, or equation roughly 15 seconds. Rounded to the closest minute, the answer is 0 minutes.

A math equation is a mechanism for connecting statements and indicating equivalence with both the equals symbol (=). An equation is an algebraic claim that asserts the equivalency of two formulae in algebra. In the calculation 3x + 5 = 14, for example, the equivalence sign separates the numbers 3x + 5 and 14. To explain the relationship among the two words on each surface of a letter, a formula can really be employed. The software and the logo are usually interchangeable. For instance, 2x - 4 equals 2.

Set T = 300 in the equation and solve for t to discover the number of minutes it takes for the oven's temperature to reach 300°F:

T = 400 - It

300 = 400 - It / subtraction T = 300

It = 400 - 300

It = 100

t = 100 / I

T = 400 minus It I = (400 minus T) / t

When we substitute T = 0 and T = 1, we get:

I = (400 - 0) / 1\sI = 400

Now we can substitute I = 400 into the equation we found before for t:

t = 100 / I\st = 100 / 400\st = 0.25

Answer:

Add to eliminate X

Step-by-step explanation:

To eliminate a variable, we need to make its coefficient equal and opposite in the two equations. In this case, we can see that the coefficient of x in both equations is the same (6x), so we can eliminate x by adding the two equations.

When we add the two equations, the x term will cancel out, leaving us with the equation:

9y = 36

We can then solve for y by dividing both sides by 9:

y = 4

Now that we know the value of y, we can substitute it back into one of the original equations to solve for x. Let's use the first equation:

6x + 5y = 12

6x + 5(4) = 12

6x + 20 = 12

6x = -8

x = -4/3

Therefore, the solution to the system of equations is x = -4/3, y = 4.

Answer:

y = (1/x)+2.05

Step-by-step explanation:

We are only given one point, so there are an infinite number of possible equations.  But forging ahead, we can come up with at least one equation of an inverse relationship containing the point (-20,2).

By inversely, the function will produce lower values of y as x increases, or vice versa.  A good first step is to say:

 y = 1/x

As the value of x increases, the value of y decreases.  Invere accomplished.

Simple, elegant, and inverse.  If it were a person, she'd be on the cover of People Magazine.

But we want any equation to include the point (-20,2).

Let's see if we can move y=1/x to include (-20,2)

y=(1/x) + b

2 = (1/(-20)) + b

2 = -(0.05) + b

b = 2.05

The equation y = (1/x)+2.05 is an inverse equation that includes point (-20,2).

See the attached graph.  Note that when x = 0, the expression (1/x) becomes (1/0).  Division by zero is not allowed (undefined).  Use caution if in the neighborhood.

(x + 2)2 + (y - 4)2 - 11 = 0

The equation of the circle in standard form is x2 + y2 + 36x - 72y + 11 = 0. To arrive at this answer, you need to complete the square for both the x and y terms in the equation. First, divide the equation by 9 to get the following:

x2 + y2 + 4x - 8y + 1 = 0

To complete the square for the x terms, add and subtract (4/2)2 = 16/4 = 4 to the equation:

x2 + 4 + y2 + 4x - 8y + 1 - 4 = -4

Simplifying gives you:

(x + 2)2 + y2 - 8y + 5 = 0

To complete the square for the y terms, add and subtract (8/2)2 = 64/4 = 16 to the equation:

(x + 2)2 + (y - 4)2 + 5 - 16 = -11
