Y is inversely proportional to V1+x. When x = 8, y = 2. Find y when x = 15.

murzikaleks [220]

Answer:

y = 1.5

Step-by-step explanation:

Given x is inversely proportional to $\sqrt{1+x}$ , then the equation relating them is

y = $\frac{k}{\sqrt{1+x} }$ ← k is the constant of proportion

To find k use the condition when x = 8, y = 2

2 = $\frac{k}{\sqrt{1+8} }$ = $\frac{k}{\sqrt{9} }$ = $\frac{k}{3}$ ( multiply both sides by 3 )

6 = k

y = $\frac{6}{\sqrt{1+x} }$ ← equation of proportion

When x = 15 , then

y = $\frac{6}{\sqrt{1+15} }$ = $\frac{6}{\sqrt{16} }$ = $\frac{6}{4}$ = $\frac{3}{2}$ = 1.5

Sqr root 8+3 Sqr root 2+ Sqr root 32 simplest form

Kisachek [45]

Answer:

 $9\sqrt{2}$ 

Step-by-step explanation:

The given question is :

$\sqrt{8} +3\sqrt{2} +\sqrt{32}$

8 = 4 * 2

32 = 16 * 2

$\sqrt{8} =\sqrt{4*2} = 2\sqrt{2} \\\sqrt{32} =\sqrt{16*2} =4\sqrt{2}$

∴ $\sqrt{8} +3\sqrt{2} +\sqrt{32}$

= $2\sqrt{2} +3\sqrt{2} +4\sqrt{2}$

= $9\sqrt{2}$

The greatest common factor of 18 and a and 20 AB

inn [45]

Answer:

Step-by-step explanation:

GCF(18, a, 20ab) = 1

18 and a do not necessarily have any factor in common, so their GCF is 1. Adding more terms to the list will not increase the GCF beyond that value.
