<span>The exponential notation
greatly simplifies calculations, especially with very large and very small
numbers. It uses positive and negative exponents to write multiples and sub-multiples of 10. i hope this helps! </span>
R = 112/1000 x 4 = 0.028 x 100 (find percentage) = 2.8%
<span>y-10=2/3(x-8)
This is because the slope is 2/3 and the point (8, 10) would be used properly here. </span>
If you multiply everything by 6, you can get rid of all of the fractions and it’ll be much easier to solve!
