noname [10]
If n is an integer, you can use induction. First show the inequality holds for n=1. You have 2^1=2>1, which is true.

Now assume this holds in general for n=k, i.e. that 2^k>k. We want to prove the statement then must hold for n=k+1.

Because 2^k>k, you have

2^{k+1}=2\times2^k>2k

and this must be greater than k+1 for the statement to be true, so we require

2k>k+1

for k>1. Well this is obviously true, because solving the inequality gives 3k>1\implies k>\dfrac13. So you're done.

If you n is any real number, you can use derivatives to show that 2^n increases monotonically and faster than n.

1 hm=100m

1.5hm=150 meters each tower is from each other.

500km(1000m/1km)=500,000 meters the wire covers.

500,000/150 = 3333.33 towers. Just because we want to be safe and have enough towers we can say we have 3334 towers in the span of 500,000 meters.

B)

1kV=1000V

500kV(1000V/1kV)= 500,000 V

There are 1.2 volts in a AA battery so we divide 500,000/1.2 = 416666.67 times larger

What is the domain of the function f(w) = 0.5(35 – 2w)? Explain your answer.
Igoryamba
The domain is all real numbers, the function is a variant of linear, which could be expressed in the form of y=mx+b as y = -w + 17.5, therefore all real numbers is the domain and the range.

I need help on this question anyone please help
Bond [772]

Answer: B.

Step-by-step explanation:

the sum of 5 x 10 with exponent 4 would be 50,000.

multiply that by 12 and it would be 600,000, which is also equal to

6 x 10 with exponent 5.

hope this helps :)
