Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9. So, how does this work?
We can think of 5.6 x 10-9 as the product of two numbers: 5.6 (the digit term) and 10-9 (the exponential term).
Y = a x² + b x + c y = 0.0473809524 · 20² + 2.221428571 · 20 - 0.005952381 = = 18.95236 + 44.42875 - 0.05952381 = 63.374978 ≈ 63.4 Answer: C ) 63.4 ft.
