Answer:

The center is at ( (-1, -2) and the radius is 5.

Step-by-step explanation:

X^2 + 2X + Y^2 + 4Y = 20

Complete the square on the x and y terms.

(x + 1)^2 -1 + (y + 2)^2 - 4 = 20

(x + 1)^2 + ( y + 2)^2 = 25 Comparing this with the standard form:

(x - h)^2 + (y - k)^2 = r^2

- the center is at ( (-1, -2) and thr radius is 5.

A fruit bowl contains 2 bananas, 5 oranges, and 4 apples in the simplest form, what is the ratio of apples to bananas in the fru

prisoha [69]

Answer:

Ratio of apple to banana is 2:1

Step-by-step explanation:

To find ratio of x type of one thing and y type of other thing we divide

x by y and ratio is written as

ratio = x:y

_________________________________

Number of banana = 2

Number of apples = 4

Ratio of apple to banana = Number of apples :Number of banana

Ratio of apple to banana = 4:2

since 4 is divisible by 2 , to get the ratio in simplest form

we divide both numerator and denominator by 2

Ratio of apple to banana = 4/2:2 /2 = 2:1

Thus,

Ratio of apple to banana is 2:1
