Answer:
dx/dt = 5√5/2
Step-by-step explanation:
Given:
dx/dt = 25 feet per second
According to Pythagoras theorem:
x² + 90² = y²
We know that x = 30 ft
So,
x² + 90² = y²
30² + 90² = y²
y = 30√10
So,
x² + 90² = y²
By taking differentiate:
2x dx/dt = 2y dy/dt
[x/y][dx/dt] = dy/dt
dx/dt = 5√5/2
True! The slopes are opposite reciprocals (aka perpendicular lines)
When a company goes public it begins selling shares of stock in a public stock market. This means that i<span>t asks for money from investors and gives them a share of the company in return of their investment. </span>
The result is: The company gets the money and the investor gets a share in the company's ownership.<span>The investor gets a share and he becomes the owner of the company but he owns only a part corresponding to the number of shares he buys.</span>
