assume that x and y are both differentiable functions of t and find rhe required values of dy/dt and dx/dt. xy=4. find dy/dt, gi
FrozenT [24]

Differentiate both sides with respect to t, using the product and chain rules on the left side.

xy = 4 \implies x\dfrac{dy}{dt} + y \dfrac{dx}{dt} = 0

When x=2, the given equation tells us that 2y=4\implies y=2. Then if \frac{dx}{dt}=10, it follows that

2\dfrac{dy}{dt} + 2\times10 = 0 \implies \dfrac{dy}{dt} = \boxed{-10}

The length of a rectangle is twice it’s width. If the area of the rectangle is 162m ^2,find its perimeter
GalinKa [24]

Answer:

{ \tt{area = length \times width}} \\ { \tt{162 = 2w \times w}} \\ { \tt{162 = 2 {w}^{2} }} \\ { \tt{ {w}^{2}  = 81}} \\ { \tt{w = 9}}

  • width, w = 9 m
  • length, l = 2 × 9 = 18 m

{ \tt{perimeter = 2(l + w)}} \\ { \tt{p = 2(18 + 9)}} \\ { \tt{p = 2 \times 27}} \\  \\ { \underline{ \tt{ \:  \: perimeter = 54 \: m \:  \: }}}
