Consider we need to find the equation of ellipse.

Given:

Ellipse is centered at the origin.

Major axis is horizontal, with length 8.

The length of its minor axis is 4.

To find:

The equation of ellipse.

Solution:

Major axis is horizontal, so standard form of ellipse is

[tex]\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1[/tex]       ...(i)

where, (h,k) is center of the ellipse and length of major axis is 2a and length of minor axis is 2b.

Ellipse is centered at the origin. So, h=0 and k=0.

Major axis is horizontal, with length 8.

[tex]2a=8[/tex]

[tex]a=4[/tex]

The length of its minor axis is 4.

[tex]2b=4[/tex]

[tex]b=2[/tex]

Substitute h=0, k=0, a=4 and b=2 in equation (i).

[tex]\dfrac{(x-0)^2}{4^2}+\dfrac{(y-0)^2}{2^2}=1[/tex]

[tex]\dfrac{x^2}{16}+\dfrac{y^2}{4}=1[/tex]

Therefore, the required equation of ellipse is [tex]\dfrac{x^2}{16}+\dfrac{y^2}{4}=1[/tex].

Answer:

X increasing by one and Y decrasees by 2

The correct relation between x and y is [tex]y=x-2[/tex].

Given information:

The table showing the values of x and y is:

x    1    2    3    4

y    -1   0    1     2

From the given table, it can be seen that with an increase in the value of x, the value of y also increases.

From the values of y, it can be seen that y increases by 1 unit with a unit increase in x.

The relation between x and y can be written as,

[tex]y=x-2\\y(1)=1-2\\y(1)=-1[/tex]

Therefore, the correct relation or equation between x and y is [tex]y=x-2[/tex].

Answer:

  y = 4.625

Step-by-step explanation:

Subtract 16.4 from both sides and collect terms.

  8.4 -6.8 -16.4 = -3.2y +16.4 -16.4

  -14.8 = -3.2y

Divide both sides by -3.2.

  -14.8/-3.2 = (-3.2y)/-3.2

  4.625 = y

The solution is y = 4.625.

Answer:

1/4

Step-by-step explanation:

There are 36 possible combinations.  Of those 36, the ones that add up to either 6 or 9 are:

1+5, 2+4, 3+3, 4+2, 5+1, 3+6, 4+5, 5+4, 6+3

There are 9 combinations that add up to either 6 or 9.  So the probability is 9/36, or 1/4.

Answer:

The function in the vertex form is y = (x + 2.5)² - 15.25

Step-by-step explanation:

The vertex form of the quadratic function y = ax² + bx + c is:

y = a(x - h)² + k, where

∵ The given function is y = x² + 5x - 9

∴ a = 1, b = 5, c = -9

→ Use a and b to find h

∵ h = [tex]\frac{-b}{2a}[/tex]

∴ h = [tex]\frac{-5}{2(1)}=-2.5[/tex]

∴ h = -2.5

→ Find y at x = -2.5

∵ y = (-2.5)² + 5(-2.5) - 9 = 6.25 - 12.5 - 9

∴ y = -15.25

∴ k = -15.25

→ Substitute a, h, k in the vertex form above

∴ y = 1(x - -2.5)² + -15.25

∴ y = (x + 2.5)² - 15.25

The function in the vertex form is y = (x + 2.5)² - 15.25

Step-by-step explanation:

This is because if you start with -10 and add 4, the number 2 would go in the blank. Also if you start at positive 10 you just subtract 4 and the number 2 would still go in the blank.

Answer:

8.74(5)+3.50=47.20

Step-by-step explanation:

She earns $47.20 that day

$51.57 is the amount emelia's job pay in a day when she works 5 and a half hours

An expression is combination of variables, numbers and operators.

Given emelia earns $8.74 per hour plus a gas allowance of $3.50 per day at her job

We need to find how much does emelia's job pay in a day when she works 5 and a half hours

Let us write the given data in the form of expression.

8.74x+3.50

Now for 5 and half hours we have to calculate

8.74(5.5)+3.50

48.07+3.50

51.57

Hence, $51.57 is the amount emelia's job pay in a day when she works 5 and a half hours

The equation of the line showing the slope of -3 is represented by the fourth graph in the image. The correct option is D.

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.

The line is passing through the points ( 0,0) and (1,-3). The slope of the line is calculated by using the formula below:-

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( -3 -0 ) / ( 1 - 0 )

Slope = -3

Therefore, the equation of the line showing the slope of -3 is represented by the fourth graph in the image. The correct option is D.

Step-by-step explanation:

The course triangle can be used to determine the transition of course stages from one to the other with labels as in the image. The angle <ABC and <BCA depends on the type of triangle we draw. Here it is 60° each.

The three main elements of the course design triangle are objectives, assessments, and instruction. All three course components must be closely correlated with one another and take into account the course setting to produce a cogent learning experience.

The Olympic triangle is a sailing course that is frequently used in racing dinghies, especially at important regattas like State, National, and World Titles, and it was also used during the Olympics. 

When looking up the course towards the top mark, the start line is frequently tilted 5 to 10 degrees to the port end, or the left end, as opposed to how the start line would be if it were parallel to the wind.

To windward of the top mark, with a finishing mark and the committee boat serving as either end of the line, is the most adaptable location to establish the finishing line.

Answer:

66

Step-by-step explanation:

Given that:

Total Number of books = 4356

Number of books in a row = number of rows

Let number of rows = b

Then number of books in each row = b

Total number of books = (number of rows * number of books per row

Hence,

4356 = b * b

4356 = b²

Take the square root of both sides

Sqrt(4356) = b

66 = b

Number of books in each row = 66

Answer:

x=1 ,y=-5

Step-by-step explanation:

3x + 10y = 47

5x - 7y = 40

____________

21x + 70y = 329. equ 1

50x - 70y = 400. equ 2

subtract equ 1 from 2

=71x = 71

divide both sides by the 71

71/71 = 71/71

x = 1

_________

to find y

substitute x into either equ 1 or equ 2

am using equ 2

5x - 7y = 40

5(1) - 7y = 40

5 - 7y = 40

7y = 5 - 40

7y = -35

divide both sides by the coffecient of y

7y/7 = -35/7

y = - 5
