The ellipse with the equation stated above is:
Position I (Option C )

An ellipse is a circle that has been extended in one direction such that it is no longer a circle but an oval.

Solution

In order to determine the position of the ellipse with the above equation, we can start by simplifying the equation.

Hence, 9x² + 16y = 144 becomes

x²/16 + y²/9 =  1 (We arrive at this by dividing both sides of the equation by 144);

The x-axis is the major axis because the biggest denominator is under the x² term.

Thus the coordinates of the vertices are as follows:

(± a, 0); (0, ± b)

Hence:

a² = 16 → a = 4

b² = 4 → b = 2

Hence the coordinates are:

(± 4, 0); (0, ± 2)

Given the above, the eccentricity is given as:

e = √(1 - (3/4)^2 = (√7)/4 = 0.6614378

Hence the ellipse is: 0.66

Answer:

[tex]a_{n}[/tex] = 11 [tex](2)^{n-1}[/tex]

Step-by-step explanation:

the nth term of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

given a₁ = 11 and a₄ = 88 , then

11 r³ = 88 ( divide both sides by 8 )

r³ = 8 ( take cube root of both sides )

r = [tex]\sqrt[3]{8}[/tex] = 2 , then the nth term is

[tex]a_{n}[/tex] = 11 [tex](2)^{n-1}[/tex]

So, before solving further, let's recall that, a deck of card have 52 cards, with 26 black cards, and 26 red cards, out of which, let's first consider red cards,so 13 of 26 are heart, and the other 13 out of 26 is diamond, now let's consider the black cards, so 13 of 26 black cards are spades and the other 13 out of 26 black cards are clubs, every type have an ace card, and 9 cards numbering from 2-10 and three face cards naming, queen, king and Jack.

The formula for interior angle of any polygon is (n-2) x 180 / n where n is the number of sides.

An octagon has 8 sides:

Part A.
interior angle = (8-2) x 180 /8

Interior angle = 135 degrees

Part B.
3x -57 = 135

Add 57 to both sides:

3x = 192

Divide both sides by 3:

The coordinate point of a point is the location (i.e. the x and y location) on the coordinate plane

From the complete question (see attachment), the coordinate of point A is:

A = (-4,1)

This means that the x-coordinate of point A is -4

In (a), we have the coordinate of point A to be

A = (-4,1)

This means that the y-coordinate of point A is 1

From the complete question, the coordinate of point B is:

B = (3,-2)

This means that the x-coordinate of point B is 3

In (c), we have the coordinate of point B to be

B = (3,-2)

This means that the y-coordinate of point B is -2

From the complete question, the x-coordinate of point C is the same as the x-coordinate of point A

Given that the x-coordinate of point A is -4

This means that the x-coordinate of point C is -4

From the complete question, the y-coordinate of point C is the same as the y-coordinate of point B

Given that the y-coordinate of point B is -2

This means that the y-coordinate of point C is -2

Answer:

256 fluid ounces

Step-by-step explanation:

2 gallons = 8 quarts

8 quarts = 18 pints

18 pints = 32 cups

32 cups = 256 fluid ounces

1 gallon = 4 quarts x 2 that's 2 gallons = 8 quarts

1 quarts = 2 pints x 8 that's 8 quarts = 16 pints

1 pints = 2 cups x 16 that's 16 pints = 32 cups

1 cup = 8 fluid ounces x 32 that's 32 cups = 256 fluid ounces

Answer:

Step-by-step explanation:

In order to solve this equation, you must isolate it on one side of the equation.

Use the distributive property.

Distributive property:

⇒ -24+12d=2(d-3)+22

Multiply.

⇒ 2(d-3)+22

⇒ 2d-2*3

⇒ 2*3=6

⇒ 2d-6

Rewrite the problem down.

⇒ 2d-6+22

⇒ -6+22=16

⇒ 2d+16

⇒ -24+12d=2d+16

Then, you add by 24 from both sides.

⇒ -24+12d+24=2d+16+24

Solve.

⇒ 12d=2d+40

Subtract by 2d from both sides.

⇒ 12d-2d=2d+40-2d

Solve.

⇒ 12d-2d=10d

⇒ 10d=40

Divide by 10 from both sides.

⇒ 10d/10=40/10

Solve.

Divide the numbers from left to right.

⇒ 40/10=4
