Answer:
4/1. ( not so sure tho)
Step-by-step explanation:
=[(6/6)×(6/6)] + [(5/6)×(6/6)] + [(6/6)×(5/6)]
=(36/36) + (30/36) + (30/36)
=(taking LCM) 96/36
=4/1.
hope this helps
Answer:
option 1
Step-by-step explanation:
(-2) (25/7)
-50/7 = -7 1/7
x = r sin θ cos Ф
x² = r² sin² θ cos² Ф
y = r sin θ sin Ф
y² = r² sin² θ sin² Ф
z = r cos θ
z² = r² cos² θ
x² + y² + z²
= r² sin² θ cos² Ф + r² sin² θ sin² Ф + r² cos² θ
= r² sin² θ (cos² Ф + sin² Ф) + r² cos² θ
= r² sin² θ + r² cos² θ
= r² (sin² θ + cos² θ)
= r² √
