Answer:
it depends on the choices
Step-by-step explanation:
The answers are A and D.
The numbers that you cannot simplify without having a radical in the answer are irrational numbers.
√(4/16) = 1/4 or -1/4, rational number
√(9/16) = 3/4 or -3/4, rational number
√(9/4) = 3/2 or -3/2, rational number
√(3/16) = √(3)/4, NOT a rational number, cannot remove radical
√(3/4) = √(3)/2, NOT a rational number, cannot remove radical
Answer:
domain: all real numbers
range: {y element R : y>=2}
Step-by-step explanation:
Y = ln |1 + t - t^3| = (1 - 3t^2)/(1 + t - t^3)
It would be 110x because they are like units, so they can be added together. Really, you are just doing 80 plus 30, and then adding an x on the end.
