Consider the two lines l1:x=−2t,y=1+2t,z=3tl1:x=−2t,y=1+2t,z=3t and l2:x=−8+4s,y=0+5s,z=5+1sl2:x=−8+4s,y=0+5s,z=5+1s find the po
seraphim [82]

At the point of intersection, the coordinates are the same:

... (x, y, z) = (-2t, 1+2t, 3t) = (-8+4s, 5s, 5+s)

We only need two of the coordinates to solve for the values of s and t. Using the x- and y-coordinates, we have

... 4s + 2t = 8 . . . . . . x2 - x1 = 0, in standard form

... 5s -2t = 1 . . . . . . . y2 - y1 = 0, in standard form

Adding these equations gives 9s=9, so s=1. Substituting into either equation gives t=2.

Using the expression for l1 with t=2, the point of intersection is

... (-2·2, 1+2·2, 3·2) = (-4, 5, 6).

_____

We could have stopped after finding the value of s, because that defines the point. By finding the value of t, we can check the solution to make sure that l1 and l2 both give the same point for the respective values of s and t. (They do.)

What is the value of the ratio of the surface area to the volume of the cylinder?
Stella [2.4K]

Answer:

Cylinder Surface Area = (2 • π • r²) + (2 • π • r • height)

Surface Area = (2 * PI * 7^2) + (2*PI*7*22)

Surface Area = 307.8760800518 + 967.6105373057

Surface Area = 1,275.4866173575 Square Inches

Cylinder Volume   =   π • r² • height

Volume = PI * 7^2 * 22

Volume = 3,386.6368805698 Cubic Inches

Surface Area to Volume = 1,275.4866173575 / 3,386.6368805698 =

0.3766233766

Answer is A

3: 1*3 ==> Prime factorization of 3

13: 1*13 ==> Prime factorization of 3

The common factor is 1.

GCF of 13 and 3 is 1
