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 √
Could you past the graphs. I would like to help:)
Answer:
R=7
Step-by-step explanation:
R=1+3w
This is a classic substitution question.
Just replace the w with 2.
R = 1+3(2)
You only need to multiply 3 with 2.
R = 1 + 6
R= 7
