Eduardwww [97]

Answer:

The value of x component changes at a rate of $\frac{dx}{dt}=4\sqrt{x}$ units per second

Step-by-step explanation:

We are given that $y=x^{\frac{1}{2}}$

Differentiating on both sides with respect to time we get

$\frac{dy}{dt}=\frac{d\sqrt{x}}{dt}\\\\\frac{dy}{dt}=\frac{1}{2}x^{\frac{-1}{2}}(\frac{dx}{dt})\\\\\frac{dy}{dt}=\frac{1}{2\sqrt{x}}\frac{dx}{dt}$

It is given that $\frac{dy}{dt}=2units/sec$

Solving for $\frac{dx}{dt}$ we get

$\frac{dx}{dt}=\frac{dy}{dt}\times 2\sqrt{x}\\\\\frac{dx}{dt}=4\sqrt{x}$

You are given the following information: Stockholders' equity = $323 million; price/earnings ratio = 14; shares outstanding = 8,

vagabundo [1.1K]

Answer:

$282.59 per share

Step-by-step explanation:

Given that,

Stockholders' equity = $323 million

price/earnings ratio = 14

shares outstanding = 8,800,000

Market/book ratio =7.7

Book Value per share:

= Stockholders' equity ÷ shares outstanding

= $323,000,000 ÷ 8,800,000

= $36.70

Market price per share:

= Book Value per share × Market/book ratio

= $36.70 × 7.7

= $282.59 per share
