If the respective sides are proportional and the corresponding angles are congruent, two triangles are said to be similar.

Triangles with the same form but different sizes are referred to as comparable triangles. Examples of related objects are all equilateral triangles and squares with any side length. In other words, two similar triangles have similar sides that are proportionately equal and similar angles that are congruent.

If two triangles have an equal number of corresponding sides and corresponding angles, they can be compared. Similar figures are objects that have the same shape but various sizes, like two or more figures.

Answer:

The point is in the second quadrant.

Substitute 6 for r.

The value of y is approximately 5.196.

Step-by-step explanation:

To convert polar coordinates (r,θ) to rectangular coordinates (x,y), we use the following formulas:

x = r * cos(θ)

y = r * sin(θ)

The point is in the second quadrant.

-This statement is true because the polar angle (120°) is in the range of 90° < θ < 180° which correspond to the second quadrant in the cartesian plane.

Start by adding 180° to θ.

This statement is False, because when converting from polar coordinates to rectangular coordinates we don't need to add 180° to the angle, we use the given angle as it is.

Substitute 6 for r.

This statement is true. In this case, the given polar coordinates are (6, 120°), so we substitute 6 for r in the formulas.

The value of x is 3.

This statement is False, to calculate x we use the formula x = r * cos(θ), so in this case x = 6 * cos(120°) = -3, which is not equal to 3.

The value of y is approximately 5.196.

This statement is true, to calculate y we use the formula y = r * sin(θ), so in this case y = 6 * sin(120°) = 6 * 0.866 = 5.196, which is approximately equal to 5.196

Step-by-step explanation:

A translation is the movement of the graphed line, either vertically or horizontally. The two given points are A and D:

A (2,11)

When the line is translated, point A becomes A' (8,22).

Pint A is moved to the right by 6, and up by 11. Lets do the same for point D to make it D'

Answer:

G to the power of 5

Step-by-step explanation:

Since there are 5 Gs, the exponent would be 5

Answer: [tex]G^5[/tex]

Step-by-step explanation: G times G times G times G times G is G times itself 5 times, which can be rewritten as [tex]G^5[/tex]

For x^2 * 5x to end in 5, x must be an odd number.

The last digit of a number is determined by its units digit. For example, the last digit of 123 is 3, the last digit of 789 is 9, and so on.

When you multiply two numbers, the last digit of the product is determined by the last digit of each factor. For example, the last digit of 3 * 4 is 2, the last digit of 6 * 7 is 2, and so on.

In this case, x^2 * 5x is a product of two numbers, x^2 and 5x. To find the units digit of x^2, we can square the units digit of x. The units digit of 5x is the units digit of x.

So, since we want x^2 * 5x to end in 5 , the last digit of x^2 * 5x has to be 5. The last digit of x^2 is the square of the last digit of x, and the last digit of 5x is 5 if x is odd and 0 if x is even.

For the equation -6x + 3y = -7 , the x-intercept and y-intercept is obtained as (1.167,0) and (0,-2.333) respectively.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

The given equation is -

-6x + 3y = -7

To find the x-intercept, substitute the value of y = 0.

-6x + 3(0) = -7

-6x + 0 = -7

-6x = -7

Use the arithmetic operation of division -

x = -7/-6

x = 1.167

To find the y-intercept, substitute the value of x = 0.

-6(0) + 3y = -7

0 + 3y = -7

3y = -7

Use the arithmetic operation of division -

y = -7/3

y = -2.333

So, the x-intercept is obtained as x = 1.167 and y-intercept is obtained as  y = -2.333.

A graph can also be plotted to find the intercepts.

Therefore, the intercepts are x = 1.167 and y = -2.333.

Pedro reaches the bootom faster than Naomi.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. The statement is not an equation if there is no "equal to" sign in it.

Equations can be divided into three categories based on their degree. The three categories of mathematical equations are as follows:

Linear Equations

Quadratic Equations

Cubic Equations

Pedro's Elevation in feet equation

E = 4200 - 800h

So, initial elevation at h = 0 is

E = 4200 ft for Pedro

Now Naomi's Initial Elevation is 3500 ft.      

So, Pedro is 4200 - 3500 = 700 ft higher than Naomi                                            

at h = 1hr

Pedro's Elevation = 4200 - 800*1 = 3400 ft

and Naomi's Elevation = 2900 ft

Speed of desending of Pedro is = total distance/ total time

= (4200 - 3400)/1 = 800 ft/hr

Speed of desending of Naomi is = total distance/ total time

(3500 - 2900)/1 = 600 ft/hr

For Elevation = 0 for Pedro

0 = 4200 - 800h

h = 4200/800 = 5.25 hr

Naomi's elevation when time is 5.5 is 200 ft

The number that should be added to the expression x²+4x to change it into a perfect square trinomial is 4.

The general form of a perfect square trinomial is (x + y)^2, where x and y are the roots of the trinomial. To check if a trinomial is a perfect square, we can try to factor it into the square of a binomial. We can also complete the square method, which involves adding and subtracting the square of half of the x-coefficient of the linear term and then grouping the resulting terms.

It is important to note that for a trinomial to be a perfect square trinomial, the constant term must be a square of an integer and the linear term must be an even number.

The slope is defined as the ratio of the change in the y-axis to the change in the x-axis.

The slope of a straight line will define the line’s angle of steepness from the horizontal whether it rises or falls. When the line neither rises nor falls, then its slope will be zero.

This is the case with a horizontal line where it extends infinitely to its left or right but without any sign of rise or fall.

In a coordinate system, points are represented by a pair of coordinate values. This pair is having y to values x-value and y-value.

For example (x,y) will represent a point on the geometrical plane. Also, (0,0) will represent the origin point.

The multiplication rule example is calculating the probability that both the balls drawn are red from an urn containing 30 red and 10 blue balls. Two balls are pulled from a bag one after the other without replacement.

As per the multiplication rule, the probability of events A and B happening is equal to the product of the probability of B happening and the conditional probability that event A happens if event B occurs.

If A and B are dependent events, then the probability of both events happening simultaneously is given by:

P(A ∩ B) = P(B).P(A|B)

If A and B are two independent events in an experiment, then the probability of both events happening simultaneously is given by:

P(A ∩ B) = P(A).P(B)

Let's solve our given example

Let A and B represent the events that the first and the second balls are pulled, which are red balls. Now, we have to calculate P(A∩B) or P(AB).

P(A) = P(red balls in first draw) = 30/40

Now, only 10 balls of blue colour and 29 balls of red colour are left in the bag. The probability of pulling a red ball in the second draw is also an example of conditional probability, where the drawing of the second ball depends on the drawing of the first ball.

Hence Conditional probability of B on A will be,

P(B|A) = 29/39

By multiplication rule of probability,
