Can Negative numbers turn into Scientific Notation?

Mathematics
1 answer:
dezoksy [38]3 years ago
8 0

Answer: Yes, negative numbers can be written in scientific notation

Examples:

-1200 = -1.2 * 10^3

-1,897,000 = -1.897 * 10^6

We simply can ignore the negative at first, then convert to scientific notation (as you normally would with any positive number). Afterward, don't forget to put the negative back in.

Latasha earned 18 points on her quiz. If 24 points is equivalent to a score of 100% what two proportions could she use to calcul
Ugo [173]
Given:
18 points on her quiz
24 points is equivalent to 100%

18 is to 24 or 18/24
x is to 100% or x/100%

18/24 = x/100%

18 * 100% = 24x
1800% = 24x
1800%/24 = x
75% = x

18/24 = 75%/100%
18 * 100% = 24 * 75%
1800% = 1800%

How far apart are the foci of an ellipse with a major axis of 26 feet and a minor axis of 24 feet?
aleksley [76]
<span>Let the major axis = 2a , and the minor axis = 2b
∴ a = 26/2 = 13    and   b = 24/2 = 12
and the equation of foci:
c² = a² - b²
    = 13² - 12² = 169 - 144 = 25
∴ c = √25 = 5

∴ The distance between the foci = 2 * 5 = 10
