What are the solutions to the equation x squared - 8x = 10?
1) 4+- radical 10
3) -4 +- radical 10
2) 4+- radical 26 4) -4 +- radical 26

the answer is a.

step-by-step explanation:

in three games of golf, alex shot two under par four times.

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.

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
