Circle O, with center (x, y) passes through the points A(0, 0), B(-3, 0), and C(1, 2). Find the coordinates of the center of the

KonstantinChe [14]

Answer:

The center of the circle is

$(-\frac{3}{2},2)$

Step-by-step explanation:

Let the equation of the circle be

$x^2+y^2+2ax+2by+c=0$ , where (-a,-b) is the center of this circle.

The points lying the circle must satisfy the equation of this circle.

A(0,0)

We substitute this point to get;

$0^2+0^2+2a(0)+2b(0)+c=0$

$\implies c=0$

B(-3,0)

$(-3)^2+0^2+2a(-3)+2b(0)+c=0$

$\implies 9+0-6a+0+c=0$

$\implies -6a+c=-9$

But c=0

$\implies -6a=-9$

$\implies a=\frac{3}{2}$

C(1,2)

$1^2+2^2+2a(1)+2b(2)+c=0$

$1+4+2a+4b+c=0$

$2a+4b+c=-5$

Put the value of 'a' and 'c' to find 'b'

$2(\frac{3}{2})+4b+0=-5$

$3+4b+0=-5$

$4b=-5-3$

$4b=-8$

b=-2

Hence the center of the circle is

$(-\frac{3}{2},2)$

A plane rises from take off and flies at an angle 11° with the horizontal runway. When it has gained 750 feet find the distance

kogti [31]

Answer:

$D=3930.632298 \approx 3930.6miles$

Step-by-step explanation:

From the question we are told that

Angle $\theta=11\textdegree$

Height of plane $h =750feet$

Generally the equation for the total distance flown is mathematically given by

$D=\frac{h}{sin\theta}$

$D=\frac{750}{sin11}$

Therefore total distance flown is

$D=3930.632298 \approx 3930.6miles$

Hello,
A=(2.21082279...,3.996803798)
$\left \{ {{h=-0.2d^2+2.25d} \atop {h=d/6+21.77/6}} \right. \\\\

\Rightarrow\ 1.2d^2-12.5d+21.77=0\\\\

\Rightarrow\ d=2.21082279..\ or\ d=8.20584..\\\\
