4. ### Find the shortest distance between the point (1,2,3) and the line r=(2+λ,1-λ,-2+2λ)?

The vector <1,-1,2> is in the direction of the given line. We need a point (x,y,z) such that (a) <x-1,y-2,z-3> "dot" <1,-1,2> = 0 and (b) (x,y,z) is on the given line, a line that could also be written as: x - 2...

5. ### Find the area of the inner loop of the limaçon with polar equation r=7cosθ−2?

I agree with answer which says = ∫ [ 0 to arccos(2/7) ] ( 49 ( 1 + cos(2u))/2 + 4 - 28cos(u)) du ( I am changing everything back to theta, since it helps me ) = ∫ [ 0 to arccos(2/7) ] ( 49 ( 1 + cos(2θ))/2 + 4 - 28cos(θ) dθ but that gives = [ 0 to...

7. ### Segment P Q is a common external tangent of circle R and circle S. The radius of circle S?

tangent is perpendicular to the radius, although your drawing doesn't show that. Not to scale. I redrew it. SR = 8+5+12 = 25 That means RWS is a right triangle with sides 25 and 7 and third side...

8. ### I found a new math formula : " if m * n = r THEN m * n = ( r-m) + m " true or false ?

You can always add and subtract the same number and not affect the result. You are essentially adding 0 to that side. This can be distilled down to: a = a - b + b
