Answer:
Step-by-step explanation:
given are four statements and we have to find whether true or false.
.1 If two matrices are equivalent, then one can be transformed into the other with a sequence of elementary row operations.
True
2.Different sequences of row operations can lead to different echelon forms for the same matrix.
True in whatever way we do the reduced form would be equivalent matrices
3.Different sequences of row operations can lead to different reduced echelon forms for the same matrix.
False the resulting matrices would be equivalent.
4.If a linear system has four equations and seven variables, then it must have infinitely many solutions.
True, because variables are more than equations. So parametric solutions infinite only is possible
Angles in a triangle ALWAYS equal 180 degrees, so 180-59-63= final angle (58 degrees) Then just use (Tan,Cos,Sin) with the angles to find the lengths, i can’t answer it as i don’t know what the triangle looks like
Answer:
The correct option is B) 
.
Step-by-step explanation:
Consider the provided information.
Angle A C B is 90 degrees and angle A B C is 35 degrees.
The required figure is shown below:
We need to find the value of c.
Use the trigonometric function: 
Hence, the correct option is B) .

The answer is <span>The </span>root<span> of a number x is another number, which when multiplied by itself a given number of times, equals x. For example the second </span>root<span> of 9 is 3, because 3x3 = 9. The second </span>root<span> is usually called the square </span>root<span>. The third </span>root<span> is susually called the cube </span>root<span> See </span>Root<span> (of a number). because then/</span>
