Step-by-step explanation:
Answer: yes
Step-by-step explanation:
Answer:
C. Irrational because it is a non-terminating and non repeating
The given plane has normal vector

Scaling <em>n</em> by a real number <em>t</em> gives a set of vectors that span an entire line through the origin. Translating this line by adding the vector <2, 1, 1> makes it so that this line passes through the point (2, 1, 1). So this line has equation

This line passes through (2, 1, 1) when <em>t</em> = 0, and the line intersects with the plane when

which corresponds the point (3, -1, 1) (simply plug <em>t</em> = 1 into the coordinates of
).
So the distance between the plane and the point is the distance between the points (2, 1, 1) and (3, -1, 1):

Answer:
3/7 =12/n
3n=7×12
3n=84
n=84÷3
n=28
3/7= t/21
3×21=7t
63=7t
t=63÷7
t=9
3/7 =k-1/2k+10
3(2k+10)=7(k-1)
6k+30=7k-7
k=37
