Two matrices are called equal matrices if they have the same order or dimension and the corresponding elements are equal.
Suppose A and B are the matrices of equal order i × j and aij = bij, then A are B are called equal matrices.
Example: Find the value of a and x if the matrices
A
=
[
4
3
1
−
5
]
,
B
=
[
a
x
−
6
1
−
5
]
are equal.
Solution:
Given that,
A = B
[
4
3
1
−
5
]
=
[
a
x
−
6
1
−
5
]
Since A and B are equal matrices the corresponding elements are equal.
Therefore,
a = 4
x – 6 = 3
x = 3 + 6
x = 9

Answer:
One
Step-by-step explanation:
9/sin(34) = 6/sinC
sinC = 0.372795269
C = 21.9, 158.1
Since 158.1 + 34 = 192.1 > 180
It will not form a triangle
So,
Only one triangle with angle 21.9° at C
Step-by-step explanation:
solving functions separately.
1st: from given data taxi charges $1.00 for the first mile.so it is first rule of function.
2nd: the company charge $0.20 per tenth of a mile.so 2nd rule of the function will be
simplifying
, 
piece wise function is f(x)={2 , 0<x<1
{x , 1<x<2
the graph of the function is given below
Answer:
y=130°
Step-by-step explanation:
180-(90+40)
180-130
50°
y=180°-50°
=130°
