Find an equation of the circle that has center (-1,6) and passes through (-6,1)
horsena [70]

Answer:

(x + 1)² + (y - 6)² = 50

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius.

The radius is the distance from the centre to a point on the circle.

Calculate r using the distance formula

r = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = (- 1, 6) and (x₂, y₂ ) = (- 6, 1)

r = \sqrt{(-6+1)^2+(1-6)^2}

  = \sqrt{(-5)^2+(-5)^2}

  = \sqrt{25+25}

  = \sqrt{50}

(h, k ) = (- 1, 6 ), then

(x - (- 1))² + (y - 6)² = (\sqrt{50} )² , that is

(x + 1)² + (y - 6)² = 50 ← equation of circle

How to work out 2(x+2)=-6+2x
nasty-shy [4]

Answer:

no solution

Step-by-step explanation:

2(x+2)=-6+2x

distribute the 2 in the parentheses: 2x+4=-6+2x

add the -6 to the other side to get rid of it on the side that it is on: 2x+10=2x

then subtract the 2x: 10=0x or 10=0

the equation is not solvable

A force of 9 lb is required to hold ​35lb crate on a hill. What angle does the hill make with the​ horizontal?
kenny6666 [7]

Answer: 14.9^{\circ}

Step-by-step explanation:

Given

Applied force is 9 lb to hold of 35 lb crate on a hill

Suppose the hill makes an angle of \theta with horizontal

There will be two component of weights i.e. along and perpendicular to the hill

Only the component along the hill pulls the crate backwards

So,

\Rightarrow 35\sin \theta=9\\\\\Rightarrow \sin\theta =\dfrac{9}{35}\\\\\Rightarrow \theta =14.89^{\circ}\approx 14.9^{\circ}

Which is equivalent to √3/√8 when denominator is "rationalized"?
TEA [102]

Step-by-step explanation:

\dfrac{\sqrt3}{\sqrt8}=\dfrac{\sqrt3\cdot\sqrt2}{\sqrt8\cdot\sqrt2}=\dfrac{\sqrt{3\cdot2}}{\sqrt{8\cdot2}}=\dfrac{\sqrt6}{\sqrt{16}}=\dfrac{\sqrt6}{4}

<h3>Used:</h3>

\sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\ \text{for}\ a\geq0\ \wedge\ b\geq0\\\\\sqrt{a}=b\iff b^2=a\ \text{for}\ a\geq0\ \wedge\ b\geq0\\\\\sqrt{16}=4\ \text{because}\ 4^2=16
