Kevin cycles 18 miles every morning as part of his exercise. The time it takes him to complete the distance varies inversely as
Lelechka [254]

Answer:

The T = \frac{18}{m} best models the amount of time it takes him to finish with kelvin cycling .

Option (A) is correct.

Step-by-step explanation:

As given

Kevin cycles 18 miles every morning as part of his exercise.

The time it takes him to complete the distance varies inversely as the speed at which he rides.

Time \propto \frac{1}{Speed}

Time = \frac{Distance}{Speed}

As m miles per hour is represented the speed.

T is the time taken by Kevin cycle for morning exercise .

Distance = 18

Putting the values in the above

T = \frac{18}{m}

Therefore the T = \frac{18}{m} best models the amount of time it takes him to finish with kelvin cycling .

Option (A) is correct.

If n^-2 = 1/16, then n could be which of the following?
Zepler [3.9K]

Answer:

The correct choice is

\boxed{n=4}

Step-by-step explanation:

The given equation is

n^{-2}=\frac{1}{16}

We rewrite the left hand side of the equation as a power(a number to a given exponent.

n^{-2}=\frac{1}{4^2}

Recall that;

\frac{1}{a^m}=a^{-m}

We apply this property to obtain;

n^{-2}=4^{-2}

Since the exponents are the same, the bases are also the same.

Therefore n=4
