Question

What is the fourth proportional of the mean proportionals between(4, 6.25); (0.0027, 300); (1.2 x 10-3,3) ?

Answer 1

Answer:

0.0108

Step-by-step explanation:

(4, 6.25) = a

(0.0027, 300) = b

(1..2 x 10-3, 3) = c

? = d

a: b :: c: d

Mean Proportional of a = = 5

Mean Proportional of b = = 0.9

Mean Proportional of c = = 0.06

a/b = c/d

D = 0.0108
