Hello.
The solutions found to radical equations are not necessarily viable. They sometimes result in inequalities, and have to be checked.
Hope I helped.
0.057x 10 is equal to .57. All you have to do is move the decimal to the right one time because there is one zero in 10.
Answer:
2
Step-by-step explanation:
consider the two points. Gradient=change in y/change in x. So 4/2=2
Answer:
tan (A-B) = ± 4/3
Step-by-step explanation:
COS (A-B) = 3/5
COS² (A-B) = (3/5)² = 9/25 = 1 - sin² (A-B)
sin² (A-B) = 1 - 9/25 = 16/25
sin (A-B) = ± 4/5
tan (A-B) = sin (A-B) / cos (A-B) = (± 4/5) / (3/5) = ± 4/3
Answer:
Teachers are idiots that's why :)
