Micah beasley invested $1 for one year, part @ 10% annual interest and part @ 14% interest his total interest for the yr was $1280. how much money did he invest at each rate

d is the only accurate one

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50

step-by-step explanation:

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
