Math tangent of a circle Also sorry my sister got a hold of it<br> ASAP!!!

sweet-ann [11.9K]

Imagine we drew a line from the centre (2,0) to the point (0,4).

Essentially the line<u> we drew from the centre to that point on the circle is perpendicular to the tangent line slope-wise</u>.

The <u>slope of that line from the centre to the point is -2</u> based on the slope's equation or formula.

slope = $\frac{y2-y1}{x2-x1}=\frac{4-0}{0-2} =-2$

Therefore the <u>tangent equation's slope is 1/2</u> since any perpendicular line's slope is the negative reciprocal of the original line's slope.

By<u> using the point-slope form, we must have the point on the tangent plane (0,4) and the slope we found which is 1/2</u>.

$y - 4 = \frac{1}{2}(x-0)\\ y= \frac{1}{2}x + 4$

Hope that helps!

X2 + y2 + 42x + 38y − 47 = 0. The equation of this circle in standard form is

erastova [34]

The Standard form of the equation of circle is (x+21)² + (y+19)² = 849

<h3>What is Standard form of circle?</h3>

To transform general form to a standard form, you can use completing the square method or you can convert this equation

x² + y² + Dx + Ey + F = 0 to x² + y² + (-2h)x + (-2k)y + (h²+k²-r²) = 0

Here, Given: x² + y² + 42x + 38y − 47 = 0

Required: Find the values of h, k, and r using this formula

x² + y² + (-2h)x + (-2k)y + (h²+k²-r²) = 0

On comparing we get,

-2h = 42

h = 21

-2k = 38

k = 19

-47 = h² + k² - r²

-47 = 21² + 19² - r²

r² = 849

r = √849

Thus, the Standard form of the equation of circle is (x+21)² + (y+19)² = 849
