Answer:
A. -2/7
Step-by-step explanation:
slope = rise/run = 2/(-7) = -2/7
Answer:
N = 10
Step-by-step explanation:
-17+ x/5 = 33
You have to find x, in this case is N
x/5 = 33 + 17
x/5 = 50
x= 50/5
x =10
N= 10
Step-by-step explanation:
S = ∫ 2π y ds
ds = √(1 + (dx/dy)²) dy
ds = √(1 + (8y)²) dy
ds = √(1 + 64y²) dy
S = ∫₁² 2π y √(1 + 64y²) dy
S = π/64 ∫₁² 128y √(1 + 64y²) dy
S = π/64 [⅔ (1 + 64y²)^(³/₂)] |₁²
S = π/96 (1 + 64y²)^(³/₂) |₁²
S = π/96 (1 + 256)^(³/₂) − π/96 (1 + 64)^(³/₂)
S = π/96 (257√257) − π/96 (65√65)
S = π/96 (257√257 − 65√65)
