What is the geometric mean of 9 and 16

12

Step-by-step explanation:

To find the geometric mean of 2 numbers, multiply them together and then take the square root

gm = sqrt(9*16)

      sqrt(ab) = sqrt(a) sqrt(b)

      = sqrt(9) sqrt(16)

     = 3 * 4

gm = 12

To find the geometric mean, write and solve 9/x = x/16 .

Cross multiply the proportion:  x² = 144

Square root both sides:  x = plus or minus 12

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

after simplifying it i got: -36.25 as my answer. hope that !
