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 = 
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>.

Hope that helps!

Answer:160 B.
Step-by-step explanation: first you seperate the two rectangles. then find volume of both by multipling lenngh times with times height then add both of your volumes.
Answer:
36.6
Step-by-step explanation:
if he puts in 12.2 as the input, then the equation would look like this f(12.2) = 3(12.2)
which would be
f(12.2) = 36.6
that is because x is the input, so if x = 12.2, then the equation above is what it would look like
