line 
Step-by-step explanation:
Let
is the required line.
<u>Slope of perpendicular lines :</u> If
and
be slope of two perpendicular lines. Them 
is perpendicular to 
the slope of
is 

Hence eqn is 
This equation passes through 

so the line is 
<u>y-intercept :</u>
Substitute 

The area of the circle is 3.14 square millimeters
<h3>Calculating Area</h3>
From the question, we are to the area of the circle
The area of a circle can be determined by using the formula,
A = πr²
Where A is the area of the circle
and r is the radius of the circle
From the given information,
r = 1 mm
and π = 3.14
Putting the parameters into the equation, we get
A = 3.14 × 1²
A = 3.14 × 1
A = 3.14 mm²
Hence, the area of the circle is 3.14 square millimeters

Answer:
answer is 142
Step-by-step explanation:
GIVEN :
a = 1/√10 ( 3i + k) and
b = 1/7 ( 2i + 3j - 6k)
TO FIND :
( 2a- b) . [ ( a x b ) x ( a + 2b)]
SOLUTION :
◆Going with the equation given,
( 2a - b) . [ ( a x b ) x ( a + 2b)]
= (2a - b) [( a×b×a) + 2(a×b)×b]
◆BAC - CAB RULE,
A×B×C = B( A.B ) - C(A.B )
= (2a- b ) [ (b (a.a ) - a (a.b ) + 2b ( a.b) -2b (a.b]
Solving further
= (2a - b )(b - 2a)
= -4a.a -b.b
=-5.
Answer:
( 2 - b) . [ ( a x b ) x ( a + 2b)] = -5
