The money would be multiplied by a factor of 16 after 28 years

<h3>How to determine the factor?</h3>

The rate is given as:

Rate = Double every 7 years

There are 4 7 years in 28 years.

So, the factor would be:

Factor = Rate^4

This gives

Factor = 2^4

Evaluate

Factor = 16

Hence, the money would be multiplied by a factor of 16 after 28 years

Enter your answer in scientific notation
Oxana [17]

It takes 1.7 x 10 ^4 for light from the sun to reach the comet.

<h3>How do scientific notations work?</h3>

The number is written in the form  a \times 10^b where we have 1 \leq a < 10

Scientific notations have some of the profits as:

Better readability due to compact representation

Its value in terms of the power of 10 is known, which helps in the easy comparison of quantities differing by a large value.

A comet is about  5.1 \times 10 ^9 km from the sun.

Light travels at about 3.0 \times 10 ^5 km per second.

\dfrac{5.1 \times 10 ^9}{3.0 \times 10 ^5}

= 1.7 \times 10 ^4

Hence, It takes 1.7 x 10 ^4 for light from the sun to reach the comet.
