Prove a/b is less than b/a when 0 < a <b

Mathematics
1 answer:
enyata [817]3 years ago
7 0

\frac{a}{b} < \frac{b}{a} \implies \\ a^2 < b^2 \implies a-b

We are given that 0<a<b, which means that 0>-a>-b if you multiply it by -1, which means what's given by our inequality is true and we are done.

A)

The four small squares are all 3x3, so the perimeter is 3+3+3+3 = 12.

12 * 4 = 48

We can find the perimeter of the large diamond shape using the Pythagorean theorem, a^2 + b^2 = c^2

a = 4

b = 4

4^2 + 4^2 = c^2

16 + 16 = c^2

32 = c^2

c = 5.65685425

So the perimeter of the large diamond shape is

5.65685425+5.65685425+5.65685425+5.65685425 = 22.627417

48+22.6 = 70.6

B)

The areas of the small squares are 3x3 = 9

9 * 4 = 36

The area of the large diamond shape is

5.65685425 * 5.65685425 = 32

36 + 32 = 68

What is the square root of 64 over 225 with a negative outside of the radical?
irinina [24]
The square root of  (64/225)  is the same as  √64 / √225 . 
That could make the whole thing easier.

Do you know what either of those separate square roots is ?

You're right !    I'm so impressed!
The square root of  64  IS  8, and the square root of  225 surely is  15 .
You really know your stuff !

So now, the expression is  √64 / √225  =  <em>8 / 15</em> .

Oh, I almost forgot, it has a negative sign before it.  OK,so the answer is <em>- 8/15</em> .
