If x² + xy – 3y = 3, then at the point (2, 1), dy/dx
Scilla [17]

Answer:

A

Step-by-step explanation:

We have the equation:

x^2+xy-3y=3

Take the derivative of both sides with respect to x:

\frac{d}{dx}[x^2+xy-3y]=\frac{d}{dx}[3]

Implicitly differentiate:

2x+y+x\frac{dy}{dx}-3\frac{dy}{dx}=0

Solve for dy/dx:

\frac{dy}{dx}(x-3)=-2x-y\\

Divide:

\frac{dy}{dx}=-\frac{2x+y}{x-3}

To find dy/dx at (2, 1), substitute 2 for x and 1 for y. So:

\frac{dy}{dx}_{(2, 1)}=-\frac{2(2)+1}{2-3}=-\frac{5}{-1}=5

Hence, our answer is A.

A spherical balloon has a circumference of 25 cm.
ArbitrLikvidat [17]

Answer:

See below ↓↓

Step-by-step explanation:

<u>Finding the radius</u>

  • C = 2πr
  • 25 = 2 x 3.14 x r
  • r = 25 / 6.28
  • r = 3.98 cm ≅ 4 cm

<u />

<u>Surface Area</u>

  • 4πr²
  • 4 x 3.14 x 4 x 4
  • 3.14 x 64
  • 200.96
  • <u>201 cm²</u>

<u></u>

<u>Volume</u>

  • 4/3πr³ = 4πr² x r/3
  • 201 x 4/3
  • 67 x 4
  • <u>268 cm³</u>
