Answer: They are not similar.

Step-by-step explanation: The angle measures are not the same for both triangles which makes them not similar to each other.

The number of triangles that can be formed from a common vertex on the polygon shown is three triangles.

To form triangles on polygons, you can draw diagonals connecting the vertices of the polygon. A diagonal is a line segment that connects two non-adjacent vertices of a polygon. By drawing diagonals, you can create triangles within the polygon.

From a hexagon, we can draw three diagonals from each vertex. So, from a common vertex, we can draw three diagonals and form three triangles. Since there are six vertices in a hexagon, we can choose any one of these vertices as the common vertex and form three triangles.

Answer:

y = x - 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (2, 0) ← 2 points on the line

m = [tex]\frac{0-(-2)}{2-0}[/tex] = [tex]\frac{0+2}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1

the line crosses the y- axis at (0, - 2 ) ⇒ c = - 2

The relationships between various components that all cooperate to create the same outcome are covered by a work. A utility is composed of numerous unique elements that work together to produce unique outcomes for each input.

Here,

To figure out how much each individual would spend, we need to divide the cost of the gift by the number of people contributing. Here are the estimates for various populations:

Each person would spend $180 ($360 / 2) if there were two people splitting the expense.

The expense would be divided among three people, who would each pay

=>  $120 = ($360 / 3).

If the cost were divided among five individuals, each person would pay =>  $72 = ($360 / 5).

Ten people would split the expense equally, each spending

=>  $36 =  ($360 / 10).

Each person would spend

=>  $3.60 = ($360 / 100)

if there were 100 people splitting the expense.

II. The algorithm is as follows:

Cost per individual equals total expense / number of individuals

=> f(N) = C/N

The monthly yield of the 20-year annuity with a present value of $425,000 and an APR of 4.5% is $8,521.68.

Monthly yield refers to the return on an investment over a 12-month period. It is calculated by dividing the total return on an investment by the amount invested and multiplying it by 100 to get a percentage figure.

This is done by taking 1 plus the interest rate divided by the number of payments per year, raised to the number of years times the number of payments per year. In this case, the annuity factor is calculated as:
1 + 0.045/12)^(20*12) = 49.81961
Then, the monthly yield is determined by dividing the present value by the annuity factor. In this case, the monthly yield is calculated as:
$425,000 / 49.81961 = $8,521.68
Therefore, the monthly yield of the 20-year annuity with a present value of $425,000 and an APR of 4.5% is $8,521.68.

The distance the ladder slipped down is 21cm.

The ladder, wall and the base of the wall form a right triangle. The ladder is the hypotenuse. The wall is the height and the distance of the foot of the ladder to the base of the wall is the base.

Pythagoras theorem would be used to determine the length of the wall.

The Pythagoras theorem: a² + b² = c²

where:

100 cm = 1 meter

3 x 100 = 300 cm

a²  + 50²  = 300²

a² + 2500  = 90,000

a² = 90,000 - 2500

a²  = 87,500

a = √87500

a = 296 cm

Height when the ladder slipped down:

(70 + 50)²  + a²  = 300²

120²  + a² = 300²

14,400 + a² = 90,000

a² = 90,000 - 14,400

a²  = 75,600

a = √75,600

a = 275

Distance the ladder slipped = 296- 275 = 21 cm

The given ordered pair is not a solution of the linear system.

Linear equations are mathematical equations that describe the relationship between two or more variables in a straight line. They can be written in the form of:

y = mx + b

To check if the ordered pair (-2, -3) is a solution to the system of linear equations, we need to substitute x = -2 and y = -3 into both equations and see if they are satisfied.

For the first equation y = 3x + 3, we have:

-3 = 3(-2) + 3

-3 = -3

This is true, so (-2, -3) satisfies the first equation.

For the second equation y = -x - 5, we have:

-3 = -(-2) - 5

-3 = 3

This is false, so (-2, -3) does not satisfy the second equation.

Since (-2, -3) satisfies the first equation but not the second equation, it is not a solution to the system of linear equations. Therefore, the answer is no.

Answer:

[tex]y = -\dfrac{1}{4}x + 1[/tex]

Step-by-step explanation:

Slope of the line can be found by taking two points on the line, (x1, y1) and (x2, y2)

Find the difference in y coordinates, y2 - y1  (called rise)

Find the difference in corresponding x coordinates x2 - x1 (called run)

rise/run gives the slope

Two distinguishable points on the line graph are (0, 1) and (4, 0)

rise = 0 - 1 = - 1
run = 4 - 0 = 4

Slope = -1/4

The equation of the line in general form is

y = mx + b

where

m = slope

b = y-intercept (value of y when x = 0)

Here m = -1/4

b = 1

So equation of the line is

[tex]y = -\dfrac{1}{4}x + 1[/tex]

The only value of x for which (-9)(x+4) = 0 is x = -4.

Calculations that include changeable altering multipliers, joining, removal, and random subdivision must be done. They could accomplish the following if they united: An algorithm, some data, and a mathematical problem.

The expression (-9)(x+4) can be simplified by using the distributive property of multiplication:

(-9)(x+4) = -9x - 36

To find the values of x for which (-9)(x+4) = 0, we can set the expression equal to zero and solve for x:

-9x - 36 = 0

Adding 36 to both sides gives:

-9x = 36

Dividing both sides by -9 gives:

x = -4

Therefore, the only value of x for which (-9)(x+4) = 0 is x = -4.

a .The probability that x of the top 25 pairs play east-west is: P(X = x) = (25 choose x) / (50 choose 25) , b. The probability that the top 5 pairs all play in the same direction is: P(all 5 play the same direction) = (1/2) * (24/49) * (23/48) * (22/47) * (21/46), c. The pmf of X is given by P(X = x) = [(n choose x) * (n choose n - x)] / [(2n choose n)], and the expected value and variance of X are E(X) = n/2 and V(X) = (n² - 1)/12.

P(X = x) = [(n choose x) * (n choose n - x)] / [(2n choose n)] yields the pmf of X. , and X's expected value and variance are, respectively, E(X) = n/2 and V(X) = (n² - 1)/12.

(a) Let X be the number of top 25 pairs that play east-west. Since there are 25 east-west pairs and 25 north-south pairs, the total number of ways to choose 25 pairs to play east-west is (50 choose 25) = 50! / (25! * 25!). Similarly, the total number of ways to choose x top pairs to play east-west is (25 choose x) * (25 choose 25 - x) = (25 choose x), since the remaining 25 pairs automatically play east-west. Therefore, the probability that x of the top 25 pairs play east-west is:

P(X = x) = (25 choose x) / (50 choose 25)

(b) The probability that the top pair plays east-west is 25/50 = 1/2. Once the top pair has been assigned a direction, the probability that the second pair plays in the same direction is 24/49, the probability that the third pair plays in the same direction is 23/48, and so on. Therefore, the probability that the top 5 pairs all play in the same direction is:

P(all 5 play the same direction) = (1/2) * (24/49) * (23/48) * (22/47) * (21/46)

(c) Let X be the number of top n pairs that play east-west, where there are 2n pairs total. Then X can take on values from 0 to n. To find the pmf of X, we can use the same method as in part (a):

P(X = x) = [(2n - n) choose x] / [(2n) choose n]

= [(n choose x) * (n choose n - x)] / [(2n choose n)]

The expected value of X is:

E(X) = sum[x * P(X = x), {x, 0, n}]

= sum[x * (n choose x) * (n choose n - x) / (2n choose n), {x, 0, n}]

Using the identity sum[x * (n choose x) * (n choose k - x), {x, 0, k}] = k * (n choose k), we can simplify this to:

E(X) = n/2

The variance of X is:

V(X) = E(X²) - E(X)²

= sum[x² * P(X = x), {x, 0, n}] - (n/2)²

= sum[x * (n choose x) * (n choose n - x) / (2n choose n), {x, 0, n}] - (n/2)²

= (n² - 1)/12

Therefore, the pmf of X is given by P(X = x) = [(n choose x) * (n choose n - x)] / [(2n choose n)], and the expected value and variance of X are E(X) = n/2 and V(X) = (n² - 1)/12, respectively.
