Homer wants to identify the center and radius of the circle defined by the equation x2 + y2 - 14x +
Klio2033 [76]

Homer has made mistake in step 2

When you complete the square, you need to add the values to both sides of equation

<em><u>Solution:</u></em>

<em><u>Given equation of circle:</u></em>

x^2 + y^2 -14x + 2y -25 = 0

Let us first calculate center and radius and find out where he did the mistake

<em><u>Step 1:</u></em>

Group the terms

x^2 -14x + y^2 + 2y = 25\\\\(x^2 -14x) + (y^2 + 2y) = 25

<em><u>Step 2:</u></em>

(x^2 -14x + 49) + (y^2 + 2y + 1) = 25 + 49 + 1

But homers step 2 is:

(x^2 -14x + 49) + (y^2 + 2y + 1) = 25

So homer has made mistake in this step

When you complete the square, you need to add the values to both sides of equation

But homer did not add 49 and 1 to right side of equation

Correct steps are:

(x^2 -14x + 49) + (y^2 + 2y + 1) = 75\\\\(x-7)^2 + (y+1)^2 = 75

Comparing general equation of circle,

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

Therefore, center is ( 7, -1) and radius is 8.66

What is an equivalent ratio ? Real world example
arsen [322]
A ratio is used to describe how two or more quantities are related. For example, we might say that a fruit drink calls for sugar crystals to be mixed with water in a ratio of 2:6. This means that for every 2 scoops sugar crystals, there will need to be 6 ounces of water. If there were 200 scoops of sugar crystals, there would need to be 600 ounces of water.

The Garcia family started the day with 222 gallons of milk. They drank 111 quart of milk for breakfast and 3 pints for lunch. Ho
Elena-2011 [213]

Answer:

11 pints of milk the Garcia family have left after lunch.

Step-by-step explanation:

The Garcia family started the day with 2 gallons of milk.

They drank 1 quart of milk for breakfast and 3 pints for lunch.

Since, 1 gallon = 8 pint

2 gallon = 16 pint

and 1 quart = 2 pint

Left amount = 16 pint - ( 2pint + 3pint)

= 16-5

= 11 pints

Hence, 11 pints of milk the Garcia family have left after lunch.
