Answer:
b. 1:4
Step-by-step explanation:
Area of cylinder A = πr²h = π(1.1).4 = 4π
Area of cylinder B = πr²h = π (2.2).4 = 16π
Ratio of their volumes = 4π/16π = 1/4 = 1:4
Answer:
two-fifths over two-sevenths equals one and two-fifths miles per hour .
The second derivative at the point (2,2) is 34/9
<u>Explanation:</u>
<u></u>
2x⁴ = 4y³
2x⁴ - 4y³ = 0
We first need to find dy/dx and then d²y/dx²
On differentiating the equation in terms of x
dy/dx = d(2x⁴ - 4y³) / dx
We get,
dy/dx = 2x³/3y²
On differentiating dy/dx we get,
d²y/dx² = 2x²/y² + 8x⁶/9y⁵

d²y/dx² = 34/9
Therefore, the second derivative at the point (2,2) is 34/9
