If f(x)= x^2+2x-6 and g(x) =3x^2-5x-7, find f(x)-g(x)

- 2x² + 7x + 1

Step-by-step explanation:

f(x) - g(x)

= x² + 2x - 6  - (3x² - 5x - 7) ← distribute parenthesis by - 1

= x² +2x - 6 - 3x² + 5x + 7 ← collect like terms

= - 2x² + 7x + 1

the answer should be:

a. 3, 4, and 6

b. 18, 24, and 36

c. 4.8, 6.4, and 9.6

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
