Question

FIND THE MEAN PROPORTIONAL OF 3.5 AND 4.5 CORRECT TO TWO PLACES OF DECIMAL.

Answer 1

Answer:

3.97

Step-by-step explanation:

Steps:

In Algebra, a mean proportional is a number that comes between two other numbers and which satisfies the equation a/x = x/b

3.5/x=x/4.5

The way to find a mean proportional is to multiply the two numbers together, then find their square root. That will be the mean proportional.

3.5*4.5 = x²

x² = 15.75

x=√15.75

x=3.9686

x=3.97

Voila :)
