A standard piece of paper is 0.05 mm thick. Let's imagine taking a piece of paper and folding the paper in half multiple times.

tatyana61 [14]

Answer:

(a) $g(n)=0.05\cdot 2^n$

(b) $g^{-1}(n)=\log_{2}20g(n)$

Step-by-step explanation:

Part A

The paper's thickness = 0.05mm

When the paper is folded, its width doubles (increases by 100%).

The thickness of the paper grows exponentially and can be modeled by the function:

$g(n)=0.05(1+100\%)^n\\\\g(n)=0.05\cdot 2^n$

Part B

$g(n)=0.05\cdot 2^n\\2^n=\dfrac{g(n)}{0.05}\\ 2^n=20g(n)\\$Changing to logarithm form, we have:\\\log_{2}20g(n)=n\\$Therefore:\\g^{-1}(n)=\log_{2}20g(n)$

Part C

If the thickness of the paper, g(n)=384,472,300,000 mm

Then:

$g^{-1}(n)=\log_{2}20g(n)\\g^{-1}(n)=\log_{2}20\times 384,472,300,000\\=\dfrac{\log 20\times 384,472,300,000}{\log 2} \\g^{-1}(n)=42.8 \approx 43\\n=43$

You must fold the paper 43 times to make the folded paper have a thickness that is the same as the distance from the earth to the moon.

A boat in still water is 32 mph. If the boat travels 72 miles upstream in the same time that it takes to travel 120 miles downst

dalvyx [7]

Dup= 72 miles
ddown= 120 miles 
v= riverspeed 
rup= 32mph - v 
rdown= 32mph + v 
t both ways= t 

d=r*t 
d/r=t 

t=ddown/rdown 
t=dup/rup 

dup/rup = ddown/rdown 

(72)/(32-v)=(120)/(32+v) 
3840-120v=2304+72v 
1536=192v 
v=8

6n+n+14=0 i need the math

Fofino [41]

Let's solve your equation step-by-step.6n+n+14=0

Step 1: Simplify both sides of the equation.6n+n+14=0Simplify: (Show steps)7n+14=0

Step 2: Subtract 14 from both sides.7n+14−14=0−147n=−14

Step 3: Divide both sides by 7.7n7=−147n=−2

Answer:n=−2
