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!

Tyler and Pearl went on a 20km bike ride that lasted for 3 hours. Because of steep hills or the trail, they walked for most of t
noname [10]

Answer: 1 hour


Step-by-step explanation:

Let the distance they walked be d_1 in time t_1 and the distance they walked be d_2 in time t_2 ,then

Walking speed=\frac{d_1}{t_1}=4

\\\Rightarrow\ d_1=4t_1

Riding speed=\frac{d_2}{t_2}=12

\\\Rightarrow\ d_2=12t_1

Also the total time taken=3 hours

∴t_1+t_2=3\\\Rightarrow\ t_2=3-t_1...(1)

Since the total distance= 20 km

∴d_1+d_2=20\\\Rightarrow4t_1+12t_2=20\\\Rightarrow4t_1+12(3-t_1)=20..............[\text{from (1)}]\\\Rightarrow4t_1+36-12t_1=20\\\Rightarrow-8t_1=-8\\\Rightarrow\ t_1=1

Thus, the they spent 1 hour time in walking.
