The distance between the point (2,1,1) and the plane x-2y=5 is​
Eduardwww [97]

The given plane has normal vector

x-2y=5\implies\mathbf n=\langle1,-2,0\rangle

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

\mathbf r(t)=\langle1,-2,0\rangle t+\langle2,1,1\rangle=\langle 2+t, 1-2t, 1\rangle

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

x-2y=5\implies(2+t)-2(1-2t)=5\implies5t=5\implies t=1

which corresponds the point (3, -1, 1) (simply plug <em>t</em> = 1 into the coordinates of \mathbf r(t)).

So the distance between the plane and the point is the distance between the points (2, 1, 1) and (3, -1, 1):

\sqrt{(2-3)^2+(1-(-1))^2+(1-1)^2}=\boxed{\sqrt5}

(b)<br> 2sin(theta) + 1/sin(theta) - 1<br> = 0 for 0 &lt;_ x &lt; 2x
Lady bird [3.3K]

Answer:

2 - 2 cos²x = sin x

2 = sin x + 2 cos² x

0 = -2 + sin x + 2(1 - sin² x)

0 = -2 sin² x + sin x + 2 - 2

0 = 2 sin² x - sin x 0 = sin x (2 sin x - 1)

sin x = 0 v sin x = 0.5

x10° + k.360° x1 = 0°, 360°

x2 = (180° - 0°) + k.360°

x2 = 180°

x3 = 30° + k.360°

x3 = 30°

x4 = (180° -30°) + k.360° x4 = 150°

HP: {x | 0°, 30°, 150°, 180°, 360°)

Write regular expressions for the following languages:a. The set of strings over alphabet {a, b, c} with at least one a and at l
dezoksy [38]

Answer and Step-by-step explanation:

a. The strings  {a, b, c} with at least one a and at least one b.

Solution: ∑ = {a, b, c}

where

(a +b +c)(a (a +b +c)*b + b (a +b +c) a (a +b +c)*

b. The set of 0’s and 1’s string whose tenth symbol from the right end is 1.

Sol: (0+1)*1(0+1)9

c. The set of  0’s and 1’s string with at most one pair of consecutive 1’s.

sol: (0+10)(11+∑)(0+10)
