All the values of x, y and z are,

z = 12.99

y = 7.01

x = 28.3 degree

We have to given that;

In a triangle,

Two angles are, 61.7 degree and 90 degree

And, One side is, 14.76.

Now, We can formulate;

sin 61.7° = Perpendicular / Hypotenuse

sin 61.7° = z / 14.76

0.88 = z / 14.76

z = 0.88 x 14.76

z = 12.99

And, By Pythagoras theorem we get;

14.76² = z² + y²

14.76² = 12.99² + y²

217.85 = 168.74 + y²

y² = 217.85 - 168.74

y² = 49.1

y = 7.01

And, By sum of all the angles in triangle, we get;

x + 61.7 + 90 = 180

x + 151.7 = 180

x = 180 - 151.7

x = 28.3 degree

The equation in standard form for the circle with center (0, 9) passing through (15/2, 5) is x²+y²-18y-54.25=0.

The given coordinate points are (0, 9) and (15/2, 5).

The standard equation of a circle with center at (x₁, y₁) and radius r is (x-x₁)²+(y-y₁)²=r²

Here, (0-7.5)²+(9-5)²=r²

56.25+16=r²

r=8.5

Now, the equation is (x-0)²+(y-9)²=8.5²

Answer:

shaded area ≈ 69.53 cm²

Step-by-step explanation:

the shaded area (A) is calculated as

A = area of square - area of circle

area of square = 18² = 324

area of circle = πr² ( r is the radius )

the diameter of the circle = 18 , so r = 18 ÷ 2 = 9

area of circle = π × 9² = 81π

then

A = 324 - 81π ≈ 69.53 cm² ( to 2 decimal places )

Answer:

(x - 0)² + (y - 9)² = (√87.25)²

Step-by-step explanation:

equation of circle is (x - a)² + (y - b)² = r², where a and b are centre of the circle and r is the circle's radius.

(x - 0)² + (y - 9)² = r²

x² + (y² - 18y + 81) = r²

x² + y² - 18y + 81 = r²

at the point (7.5, 5):

(7.5)² + (5)² - 18(5) + 81

= 87.25

so r² = 87.25.

in standard form:

(x - 0)² + (y - 9)² = (√87.25)²

Answer:

The inverse function is:

f(x)=√x−2

Step-by-step explanation:

To find the inverse function of y=f(x) you have to transform the formula to calculate x in terms of y.

y=x2+2

x2=y−2

x=√y−2

Now we can change the letters to follow the convention that x is the independent variable and y is the function's value:

y=√x−2

You have to calculate the domain of the result function.

Here you have the expression under square root sign, so the domain is the set where x−2≥0

To find the previous population, we need to determine the population before the 27% decrease. Here's how we can calculate it:

Let's assume the previous population is P.

According to the problem, the current population is 7300, which represents 100% - 27% of the previous population:

(100% - 27%) * P = 7300

To simplify the equation, convert 27% to decimal form:

(100% - 0.27) * P = 7300

Simplifying further:

0.73P = 7300

Divide both sides of the equation by 0.73:

P = 7300 / 0.73

P ≈ 10000

Therefore, the previous population was approximately 10,000.

The total number of data values (games played) represented in the table is 14.

To determine the total number of data values (games played) represented in the frequency table, we need to sum up the frequencies for each category (number of goals scored).

The frequency represents the number of games in which a particular number of goals was scored.

Let's calculate the total number of games played by summing up the frequencies:

Total number of games played =

Frequency of 0 goals + Frequency of 1 goal + Frequency of 2 goals + Frequency of 3 goals + Frequency of 4 goals + Frequency of 7 goals + Frequency of 9 goals

Total number of games played = 1 + 3 + 2 + 4 + 2 + 1 + 1

Total number of games played = 14

We must add the frequencies for each category (number of goals scored) to get the total number of data values (games played) reflected in the frequency table.

The number of games with a specific amount of goals scored is the frequency.

Let's add up the frequencies to determine the total number of games played:

Total games played = Frequency of 0 goals, Frequency of 1, Frequency of 2, Frequency of 3, Frequency of 4, Frequency of 7, and Frequency of 9 goals.

Total games played: 1 plus 3 plus 2 plus 4 plus 2 plus 1 plus 1

14 games were played in total.

The coordinate of point X" after translating segment XY along the vector <-3, 1> and then rotating it 90 degrees is X" (4, 5).

To find the coordinate of point X" after translating segment XY along the vector <-3, 1> and then rotating it 90 degrees, we need to follow these steps:

Translation: Add the components of the translation vector <-3, 1> to the coordinates of point X(-2, 3) to get the new coordinates of X'.

X' = (-2 + (-3), 3 + 1) = (-5, 4)

Now, we have the translated endpoint X'.

Rotation: To rotate the point X' by 90 degrees, we need to swap the x and y coordinates and negate the new x coordinate.

X" = (y-coordinate of X', -x-coordinate of X')

X" = (4, -(-5))

X" = (4, 5)

Therefore, the coordinate of point X" after translating segment XY along the vector <-3, 1> and then rotating it 90 degrees is X" (4, 5).

In summary, we first translate point X(-2, 3) along the vector <-3, 1> to get X' (-5, 4). Then, we rotate X' by 90 degrees to obtain X" (4, 5).

The shepherd could put 7 sheep in the second pen and 49 sheep in the third pen.

We have,

Let's solve the problem step by step.

-Let's assume that the number of sheep in the second pen is 7x, where x is a positive integer representing the number of multiples of 7.

Similarly, let's assume that the number of sheep in the third pen is 7y, where y is a positive integer representing the number of multiples of 7.

According to the given information, the shepherd placed a total of 63 sheep in the pens:

7 + 7x + 7y = 63

We can simplify this equation by dividing both sides by 7:

1 + x + y = 9

Now we need to find positive integer values for x and y that satisfy this equation.

Since we know that there were more sheep in the third pen, y should be greater than x.

Let's try different values for x and y:

If x = 1, then y = 9 - (1 + 1) = 7

If x = 2, then y = 9 - (2 + 1) = 6

If x = 3, then y = 9 - (3 + 1) = 5

If x = 4, then y = 9 - (4 + 1) = 4

We can see that when x = 1, y = 7, which satisfies the condition that there were more sheep in the third pen.

Therefore, the number of sheep in the second pen (7x) is 7 x 1 = 7, and the number of sheep in the third pen (7y) is 7 x 7 = 49.

Thus,

The shepherd could put 7 sheep in the second pen and 49 sheep in the third pen.

A linear equation is an algebraic equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.  The standard form of a linear equation in one variable is of the form Ax + B = 0, where x is a variable, A is a coefficient, and B is a constant.

the given equation is 2x+4y = 20

to find the value of x, make y to be zero first

2(0) + 4y = 20

4y = 20 making y the subject of the relation to have

y = 5

Then when y = 0

To determine whether the given sequence is geometric, we need to check if there is a common ratio between consecutive terms.

Let's examine the given sequence:

1/3, 2/9, 4/27, 8/81, 16/243...

To find the ratio between consecutive terms, we can divide each term by its preceding term:

(2/9)/(1/3) = 2/9 × 3/1 = 2/3

(4/27)/(2/9) = 4/27 × 9/2 = 4/6 = 2/3

(8/81)/(4/27) = 8/81 × 27/4 = 2/3

(16/243)/(8/81) = 16/243 × 81/8 = 2/3

The width of the vegetable garden is 8 feet.

To determine the width of the vegetable garden.

Given information:

Flower garden length = 6 feet

Flower garden width = 4 feet

Vegetable garden length = Flower garden length

Area of the flower garden = half the area of the vegetable garden

To find the width of the vegetable garden, we need to find the area of both gardens.

Area of the flower garden = length × width

Area of the flower garden = 6 feet × 4 feet

Area of the flower garden = 24 square feet

Since the area of the flower garden is half the area of the vegetable garden, we can set up the following equation:

24 square feet = (1/2) × Area of the vegetable garden

To solve for the area of the vegetable garden, we multiply both sides of the equation by 2:

2 × 24 square feet = Area of the vegetable garden

48 square feet = Area of the vegetable garden

Now that we know the area of the vegetable garden is 48 square feet, we can find the width.

Area of the vegetable garden = length × width

48 square feet = 6 feet × width

To solve for the width of the vegetable garden, we divide both sides of the equation by 6:

48 square feet / 6 feet = width

8 feet = width

Therefore, the width of the vegetable garden is 8 feet.
