The coast Guard is called back to work after the government shutdown to find passengers clinging to a buoy. The boat the passengers were on is 1.7 miles away from shore and the buoy is 1.3 miles from shore. Given the diagram of the situation
with the altitude in the right triangle how high is the helicopter above the buoy in miles?

answ9x x 3=

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

answer: i think it is c
