Answer: $\bold{\dfrac{4\pm \sqrt{6}}{2}}$

<u>Step-by-step explanation:</u>

$\dfrac{3}{y-2}-2=\dfrac{1}{y-1}\\\\\\\text{Multiply by the LCD (y-2)(y-1) to clear the denominator:}\\\\\dfrac{3}{y-2}(y-2)(y-1)-2(y-2)(y-1)=\dfrac{1}{y-1}(y-2)(y-1)\\\\\\3(y-1)-2(y-2)(y-1)=1(y-2)\\\\3y-3-2(y^2-3y+2)=y-2\\\\3y-3-2y^2+6y-4=y-2\\\\-2y^2+9y-7=y-2\\\\0=2y^2-8y+5\quad \rightarrow \quad a=2,\ b=-8,\ c=5\\\\\\\text{Quadratic formula is: }x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\\\x=\dfrac{-(-8)\pm \sqrt{(-8)^2-4(2)(5)}}{2(2)}\\\\\\.\ =\dfrac{8\pm \sqrt{64-40}}{2(2)}$

I need help with this problem

Irina-Kira [14]

Answer:

3695.5 m

1530.73 m

Step-by-step explanation:

Given in the question,

The distance probe travels at an angle of depression 67.4 from the ship to the ocean surface = 4000m

We will use trigonometry identities

<h3>sinФ = opposite / hypotenuse</h3><h3>cosФ = adjacent/ hypotenuse</h3>

distance of probe from top of sea to surface = x

cos(90 - 67.5) = x / 4000

x = 3695.5 m

horizontal distance from ship to probe = y

sin(90-67.5) = y / 4000

y = 1530.73 m
