Answer:

(-5, 38) and

(5,18)

Step-by-step explanation:

$x^2-2x+3=-2x+28\\ x^2-2x+3+2x=28\\ x^2 = 28-3=25\\ x^2-25=0\\ x^2-5^2 =0\\ (x-5)(x+5)=0\\ x = 5 \ or \ x=-5$

so the solutions are

(-5, 38) and

(5,18)

The endpoints of the side of a square lie on the circle and the opposite side of the square tangent to the circle at its midpoin

Answer:

$\displaystyle \frac{L}{r}=\frac{8}{5}$

Step-by-step explanation:

<u>Circle and Square </u>

We have a geometric construction as shown in the image below. We can see that

$\displaystyle r+h=L$

Or, equivalently

$\displaystyle h=L-r$

The triangle formed by r,h and L/2 is right, because the opposite side of the square is tangent to the circle at its midpoint. This means we can use Pythagoras's theorem:

$\displaystyle r^2=h^2+\left(\frac{L}{2}\right)^2$

Replacing h

$\displaystyle r^2=(L-r)^2+\left(\frac{L}{2}\right)^2$

Expanding squares

$\displaystyle r^2=L^2-2Lr+r^2+\frac{L^2}{4}$

Simplifying

$\displaystyle 2Lr=L^2+\frac{L^2}{4}$

Multiplying by 4

$\displaystyle 8r=4L+L$

Joining terms

$\displaystyle 8r=5L$

Solving for the ratio L/R as required

$\displaystyle \frac{L}{r}=\frac{8}{5}$

Step-by-step explanation:

14/5 = 10/x hours (divide both sides by 10)

50/14 = x (3.57 taps)
