Answer:

5) 1/3=x/12

12=3x

3x=12 (divide both sides)

12 divided by 3 = 4

therefore, x = 4

6) 5/9=25/y (cross multiply the numbers)

after cross multiplying you should get: 5y=225

divide both sides to get 45

therefore, y = 45

7) 26/z = 13/22 (cross multiply numbers)

after cross multiplying, you should get: 572=13z (swap the numbers)

after swapping the number, you should get: 13z=572 (divide both sides)

after dividing you should get 44

therefore, z = 44

8) b/30 = 2.6/1.5 (simplify expression)

after simplifying you should get: b/30=26/15 (cross multiply after)

after cross multiplying you should get: 15b = 780 (divide both sides)

after dividing both sides, you should get: 52

therefore, b = 52

Hope this helps:)!

Which coordinate pair identifies the center of the circle represented by 4x2 + 4y2 − 16x − 24y + 36 = 0.
Flura [38]

Answer

Find out the which coordinate pair identifies the center of the circle represented by 4x² + 4y² − 16x − 24y + 36 = 0.

To prove

The general equation of the circle is

(x - h)² + (y - k)² = r²

Where h,k are the centre and r is the radius.

4x² + 4y² − 16x − 24y + 36 = 0

Divided both side by 4.

x² + y² − 4x − 6y + 9= 0

Add and subtract 4 and 9

x² + y² − 4x − 6y + 4 -4 +9 - 9 +9= 0    

x² + y² − 4x − 6y + 4 -4 + 9 - 9 +9= 0    

x² + 4 - 2× 2 × x + y² + 9 - 2 × 3 × y = 9 + 4 - 9

using the formula ( a + b )² = a² + b² +2ab

(x - 2)² +  (y - 3)² = 2²

Compare this with the general equation of circle.

Thus

h = 2 , k = 3

Option A is correct .

Need some more help please!
Vikki [24]

For this case we have that by definition\pi equals 180 degrees.

We must convert 135 degrees to radians, then:

135 * \frac {\pi} {180} =\\135 * \frac {3.14} {180} =\\\frac {423.9} {180} = 2.355

Rounding off we have:

2.4 radians.

Answer:

2.4 radians
