The answer to your question is 3
Reasons : -9+ 3•4= -9+12= 3.
Explanation:
log(x) - log(y) = log(x/y)
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)
Answer:
r=2639
Steps below
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
95+r=2736−2
95+r=2736+−2
r+95=(2736+−2)(Combine Like Terms)
r+95=2734
r+95=2734
Step 2: Subtract 95 from both sides.
r+95−95=2734−95
r=2639
Hope this helps.
