Answer:

Option (B) is correct.

\frac{x^2}{20}+\frac{y^2}{20}=1  equation will produce the graph shown.

Step-by-step explanation:

Given  a graph showing circle .

We have to determine the equation that will produce the graph shown.

Consider the given graph.

It shows a circle with radius 4.5

The general equation of circle is represented by x^2+y^2=r^2    

Since option (A) represents the equation of hyperbola.

Option (C) represents the equation of circle with radius 4, but the given graph has radius grater than 4 .

Option (D) can be rewritten as  by dividing by 6,

x^2+y^2=\frac{144}{6}=24  which is a equation of circle with radius 4.9 (approx)

Thus, only Option (B) works for the given graph.

\frac{x^2}{20}+\frac{y^2}{20}=1

Multiply , by 20 , we get,

x^2+y^2=20 also, \sqrt{20}=4.47(approx)

Thus, Option (B) is correct.

\frac{x^2}{20}+\frac{y^2}{20}=1

What is the length of the segment joining the points at (-6, 8) and (6, 3)?
melisa1 [442]

Answer:

13 units

Step-by-step explanation:

So the length of those 2 points is 6+6 = 12.

The height would be 8-3 =5

Using pythagoras, you can find out the length of the line joining the 2 points so:

5^2 + 12^2 = 169

\sqrt{169} = 13 units

1986                                          6,300

1987                                           6,700

1988                                           7,200

1989                                           7,850

1990                                           8,250

1991                                            8,450

2001                                            8,155

The information above describes the real GDP per capita for a country for the period from 1985 through to 2001. If a new business cycle began in 1985, how long was this cycle? In which year did the peak occur? The trough occurred in which year? How long was the expansion? How long was the recession?

Step-by-step explanation:

a.If a new business cycle began in 1985, how long was this cycle?

The business cycle describes the rise and fall in production output of goods and services in an economy. In the data given above, a business cycle is complete in the year 1998. If the cycle started in 1985 then it was 14 years long.

b. In which year did the peak occur? The trough occurred in which year?

In the data given above, the peak occured in year 1993 (GDP per capita of 8,575) and trough occurred in the year 1998 (GDP per capita of 7,925).

c. How long was the expansion? How long was the recession?

Expansion was 9 years long (1985-1993) and recession was of 5 years (1994-1998).

The number of men is 3 times the number of woman. The number of women is 5 times the number of children at the mall
ahrayia [7]
We would first need to figure out how many women there are in order to know about the number of men. 

5c = w (<em>women</em>)
3w = m (<em>men</em>)

There are 730 children and to find out the number of women we need to do 
5 \times 730 = w
where w = 3650 

There are 3650 women. TO figure out the number of men, we need to do 3 \times 3650 = m
where m = 10950

Therefore, the number of men in the mall is 10,950.
