I’m really sorry but i don’t know this answer so hit me if you want I’ll try
The rref of the identity matrix is the identity matrix because the identity matrix itself is already in Row Reduced Echelon Form.
Thus, no elementary row operations are required to change the identity matrix into Row Reduced Echelon Form.
Have an awesome day! :)
Since the angle is connected to the center of the circle, that makes it a central angle. The 30° angle is the same as arc AYB. so AYB is 30°
I might be wrong but you tell me,
The father is 60 years old.
Son lives to be 60.
Total is 120.
Both die at the age of 60.
Could the son have been a newborn?
Idk. I don't understand it.
Wait, sum of present ages is 60. The son has to be younger by at least 20. Double it again. No, even then newborn is 0 and then 60= 60. Son lives toll he's 60 and dies, 120. Sorry, I tried. What are your possible choices?
