Answer: The answer is (C).
Step-by-step explanation: The given statement is - "Two matrices are row equivalent if they have the same number of rows". We are to explain whether the statement is true or false.
What are row equivalent matrices? The answer to this question is -
Two matrices are said to be row equivalent if one of the matrices can be obtained from the other by applying a number of elementary row operations. Or, we can say two matrices of same order are row equivalent if they have same row space.
Thus, the correct option is (C).
Answer:
The function is continuous at x = 36
Step-by-step explanation:
From the question we are told that
The function is 
The point at which continuity is tested is x = 1
Now from the definition of continuity ,
At function is continuous at k if only
So
![\lim_{x \to 36}f(x) = \lim_{n \to 36}[x * \sqrt{ \frac{x}{ (x-6) ^2 } }]](https://tex.z-dn.net/?f=%5Clim_%7Bx%20%5Cto%2036%7Df%28x%29%20%20%3D%20%20%5Clim_%7Bn%20%5Cto%2036%7D%5Bx%20%2A%20%20%5Csqrt%7B%20%5Cfrac%7Bx%7D%7B%20%28x-6%29%20%5E2%20%7D%20%20%7D%5D)
Now
So the given function is continuous at x = 36

Answer:
√25
Step-by-step explanation:
√25 = √(5²) = 5 . . . . a rational number
The other roots are not the roots of perfect squares, so are irrational.
Answer:
30° 150° 150°
Step-by-step explanation:
there are multiple ways you could get to this answer. the easiest way is to use linear angles (angles that will add up to 180°). so 180°-30°=150°. then use vertical angles (angles across from each other at an intersection are always equal) and figure out that 30° and 150° are the last two angles
