a₁₁ = -11
a₁₂ = -16
a₁₃ = 6
a₁₄ = -10
Step-by-step explanation:
The matrix A will therefore appear as;
[ -11 -16 6 -10 ]
Adding matrices of the same size involves adding the individual elements;
A = [ 0 1 -2 3 ] – [ 11 17 -8 13 ]
Substance the individual element in the two matrices that share the same coordinates;
0 – 11 = -11
1 – 17 = -16
-2 - -8 = 6
3 – 13 = -10
The perpendicular line to x-6y=2, and passing through (2, 4) is y=-6x+16

Answer:
1/10 per sec
Step-by-step explanation:
When he's walked x feet in the eastward direction, the angle Θ that the search light makes has tangent
tanΘ = x/18
Taking the derivative with respect to time
sec²Θ dΘ/dt = 1/18 dx/dt.
He's walking at a rate of 18 ft/sec, so dx/dt = 18.
After 3seconds,
Speed = distance/time
18ft/sec =distance/3secs
x = 18 ft/sec (3 sec)
= 54ft. At this moment
tanΘ = 54/18
= 3
sec²Θ = 1 + tan²Θ
1 + 3² = 1+9
= 10
So at this moment
10 dΘ/dt = (1/18ft) 18 ft/sec = 1
10dΘ/dt = 1
dΘ/dt = 1/10 per sec
