If the geometric mean of a and 28 is 16 sqrt 7 find a
kozerog [31]

Answer:

a = 64

Step-by-step explanation:

The geometric mean of 2 numbers a and b is \sqrt{ab} , then

\sqrt{28a} = 16\sqrt{7} ( square both sides )

28a = (16\sqrt{7} )² = 1792 ( divide both sides by 28 )

a = 64

Please someone help me!!!! SHOW ALL WORK! ive been stuck on this question for 2 days!! :((((((
Otrada [13]

Step-by-step explanation:

x² + y² − 8x + 10y − 8 = 0

Rearrange:

x² − 8x + y² + 10y = 8

To complete the square, take half of the x and y coefficients, square it, then add the result to both sides.

(-8/2)² = 16

(10/2)² = 25

x² − 8x + 16 + y² + 10y + 25 = 8 + 16 + 25

x² − 8x + 16 + y² + 10y + 25 = 49

Factor the squares:

(x − 4)² + (y + 5)² = 49

The center is (4, -5) and the radius is 7.
