Both triangles ABC and DEF are similar to each other based on angle angle similarity

Two triangles are said to be similar if the ratio of the corresponding sides of both triangles are proportional to each other. Also, all the three angles of one triangle are equal to that of the other triangle.

The angle angle (AA) similarity theorem states that two triangles are similar if two angles of one triangle is equal to that of the other triangle.

It is possible to construct a triangle whose sides are 10.2 cm 5.8 cm and 4.5 cm because the sum of two sides are smaller than third sides.

In the given question, we have to check that it is possible to construct a triangle whose sides are 10.2 cm 5.8 cm and 4.5 cm.

The sum of the two sides must always be greater than the third side in order to determine whether or not the given sides may form a triangle.

To check this we firstly add the 10.2 and 5.8

10.2 + 5.8 > 4.5

16 > 4.5

Now we add 10.2 and 4.5

10.2 + 4.5 > 5.8

14.7 > 5.8

Now we add 5.8 and 4.5

5.8 + 4.5 > 10.2

10.3 > 10.2

It is possible to construct a triangle whose sides are 10.2 cm 5.8 cm and 4.5 cm because the sum of two sides are smaller than third sides.

A. Without computing, the sum of 2, 3, and -2 is 3.

B. The explanation that supports the answer in Part A is (A) 2 and -2 are additive inverses and the sum of any number and its additive inverse is zero. The integer 3 is positive, so the sum with be positive.

An additive inverse of a number is the value that results in zero when added to the original number. It is the value that we add to a number in order to get zero. If an is the original number, then its additive inverse is minus a, i.e., -a, such that;

a+(-a) = a – a = 0

By changing the sign of a number, we can find its additive inverse. A positive number's additive inverse is negative, while a negative number's additive inverse is positive. Except for the sign, the numerical value will not change. The additive inverse of 8 is -8, for example, while the additive inverse of -6 is 6.

This is demonstrated by using y = changes in different as the formula for the single direction, where m denotes the slope while c denotes the y-intercept. In the intercepting form of the equation, the line's slope (m) the y-intercept (b) are indicated. Slope and y-intercept are, respectively, m and b for equations with the intercept form (y=mx+b). Additionally, certain equations might be modified to look like slope intercepts. When y=x is written as y=1x+0, for example, the slope and una become 1 and 0, respectively.

Here,

In this case, you must first set up your equation in the "Slope intercept" form.

6x=8y+10

Because your y should be alone, add 8y to each of your sides.

8y + 6x = 10

Since subtraction is the exact reverse of addition, multiply 6 times on both sides.

8y = 6x + 10

You will now divide both sides by 8. You will be alone yourself while completing this.

y= 6/8x + 10/8

The midpoint formula is a mathematical formula used to find the midpoint of a line segment, given the coordinates of the two endpoints of the segment. In class 11, it is defined as:

Midpoint = ( (x1 + x2)/2 , (y1 + y2)/2 )

Where (x1, y1) and (x2, y2) are the coordinates of the two endpoints of the line segment, and (x, y) are the coordinates of the midpoint of the segment.

For example, if the two endpoints of a line segment are (5,6) and (9,11)

Midpoint = ( (5 + 9)/2 , (6 + 11)/2 )

Midpoint = (7,8.5)

The midpoint of the line segment with endpoints (5,6) and (9,11) is (7,8.5)

Step-by-step explanation:

n to the power of 6, also written as n⁶, is a mathematical operation that raises the number n to the sixth power. This means that n is multiplied by itself six times.

For example, if n = 2, then n⁶ = 2 × 2 × 2 × 2 × 2 × 2 = 64.

Exponentiation is a mathematical operation that is used to represent repeated multiplication. The number that is being multiplied is called the base, and the number that represents how many times the base is being multiplied is called the exponent. In the case of n⁶, the base is n and the exponent is 6.

In general, when raising a number to a power, the result is the product of that number multiplied by itself the number of times represented by the exponent. For example, n³ = n × n × n and n⁴ = n × n × n × n.

In addition to being a mathematical operation, exponentiation also has practical applications in fields such as computer science, engineering, and physics.

For example, in computer science, exponentiation is used to perform fast computations, such as in the process of encryption and decryption. In engineering and physics, exponentiation is used to calculate rates of growth, such as in the case of compound interest and radioactive decay.

Answer:

The break even point is 380.

Step-by-step explanation:

36x + 200 = 76x

200 = 76x - 36x

200 = 40x

200/40 = x

5 = x

C = 36(5) + 200            R = 76(5)

C = 180 + 200              R = 380

C = 380

Answer:

The breakeven point is 5 units

Step-by-step explanation:

C is the cost ($) and R is the revenue ($).

We are told that :

R=76x

C=36x+200

Profit would be the Revenue minus the Cost:

Profit = R - C

The "breakeven point" is the situation in which there is neither a profit nor a loss.  That means that the total profit equals the total cost for x units. We want to find the value of x that would result in no profit or loss: Profit = 0.

0 = R-C

====

Profit = 76x - (36x+200)

Profit = 40x - 200

0 = 40x - 200         [The Breakeven Point]

-40x = -200

x = 5 units

5 units results in 76*5 or $380 in revenue.

5 units results in a cost of 36*(5)+200 or $380 in costs.

The result is breakeven (Profit = $390 - $380) of $0.00

The division of 16 - 8x - 7x² + 2x³ by x - 4 will have a quotient of 2x² + x - 4 and a remainder of 0 using synthetic division.

The procedure for synthetic division involves the following steps:

Divide.

Multiply.

Subtract.

Bring down the next term, and

Repeat the process to get zero or arrive at a remainder.

We shall rearrange 16 - 8x - 7x² + 2x³ to become 2x³ - 7x² - 8x + 16 and then divide by x - 4 as follows;

2x³ divided by x equals 2x²

x - 4 multiplied by 2x² equals 2x³ - 8x²

subtract 2x³ - 8x² from 2x³ - 7x² - 8x + 16 will give x² - 8x

x² divided by x equals x

x - 4 multiplied by x equals x² - 4x

subtract x² - 4x from x² - 8x will give us -4x + 16

-4x divided by x equals -4

x - 4 multiplied by -4 equals -4x + 16

subtract -4x + 16 from -4x + 16 will result to a remainder of 0
