Graph x2 + y2 = 9. What are its lines of symmetry?

Answers

            Equation given in the question represents a circle.

            Therefore, there will be infinite lines of symmetry.

Line of symmetry of a figure:

  •  Line of symmetry of a figure is the line over which half of the figure overlaps the other half.

Given in the question,

  •  Graph represented by the equation → x² + y² = 9

Equation given in the question is in the form of

(x-0)^2+(y-0)^2=3^2

Since, general equation of a circle is given by,

(x-h)^2+(y-k)^2=r^2        

Therefore, given equation represents a circle.

By definition, a circle has infinite lines of symmetry passing through the center.

      Therefore, given equation will have infinite lines of symmetry.

Answer:

It has infinitely many line of symmetry. All diameters are line of symmetry.

Step-by-step explanation:

Given: Equation is x² + y² = 9

To find: line of symmetry of given equation

Given equation is the equation of circle.

x² + y² = 9

re write,

(x-0)² + (y-0)² = 3²

by comparing given equation with standard equation of circle ,

(x-h)² + (y-k)² = r²

we get, h = 0 , k = 0 , r = 3

⇒ Centre of circle = ( 0 , 0 ) and radius of circle = 3 unit

Since It is a circle. so it has Infinitely many line of symmetry

Also, All diameters of this circle are line of symmetry for this circle.

The options can be arranged in the following manner:

0 to 1 is decreases slowly,

1 to 2 is increases quickly,

2 to 3 is decreases quickly,

3 to 4 is increases slowly.

As we know there are four trends which can be classified as:

1. Increasing Trend (Upward trend)

  a. Increasing quickly

  b. Increasing slowly

2. Decreasing Trend (Downward trend)

  a. Decreasing quickly

  b. Decreasing slowly

Now, compare the two increasing trends and the two decreasing trends with each other. Further, see which of the two is fast and slow. The one with the greater slope is the fast trend and the one with the lower slope is the one with the slow trend.

Hence, the options can be arranged in the following manner:

0 to 1 is decreases slowly,

1 to 2 is increases quickly,

2 to 3 is decreases quickly,

3 to 4 is increases slowly.

The labels for the 4 trends are; decreases slowly, increases fastly, decreases fastly and increases slowly respectively.

Explanation:

  • First, we need to identify how many trends there are i.e. upward (increasing )trends and downward (decreasing )trends. In the given graph, there are two upward trends and two downward trends.
  • Next, we need to compare the two increasing trends and the two decreasing trends with each other. By doing so, we need to see which of the two is fast and slow. The one with the greater slope is the fast trend and the one with the lower slope is the one with the slow trend.
  • In the given trend the first trend is the decreasing slowly trend, the third trend is decreasing fastly. The second trend is increasing fastly and the fourth trend is increasing slowly.

The answer would be -5
The answer would be negative five. Anything multiplied by zero is zero so that cancels the 2x^3, leaving you 0-5. Which is -5. 

A 12 ounce bottle of shampoo last enrique 16 weeks.how lonh would you expect an 18 ounce bottle of the same brand to last him?

Answers

For Enrique a 12 ounce bottle lasts for 16 weeks. This is a known fact. We need to find the amount of days or weeks an 18 ounce bottle of the same brand of shampoo last.
Now
12 ounce bottle lasts = 16 weeks
                                   = (16 * 7) days
                                   = 112 days
18 ounce bottle lasts = (112/12) * 18
                                  = 168 days
                                 = 168/7 weeks
                                 = 24 weeks
So 18 ounce of the same brand of shampoo will last for 24 weeks.

Answers

Answer:

  D  Numbers that can be written as fractions

Step-by-step explanation:

A rational number is one that can be written as a ratio: a fraction with integer numerator and denominator.

__

The term "decimal" as used here is sufficiently non-specific that we cannot seriously consider it to be part of a suitable answer. A terminating or repeating decimal will be a rational number. A non-terminating, non-repeating decimal will not be a rational number.

While integers and whole numbers are included in the set of rational numbers, by themselves, they do not constitute the best description of the set of rational numbers.

What is the value of n in the equation: 8n + 9 = -n +5

Answers

Answer:

n = -4/9

Step-by-step explanation:

8n + 9 = -n +5

Add n to each side

8n+n + 9 = -n+n +5

9n +9 = 5

Subtract 9 from each side

9n+9 - 9 = 5-9

9n /9 = -4/9

Divide each side by 9

n = -4/9
