What is the linear equation that was used to generate the values in the table? Write an expression for y as a linear function of x:
In physics, the (absolute) pressure P in newtons per square meter at a point h meters below the surface of a body of water is shown to be a linear function of h. When h = 0.5 m,
P = 1.013*10^8 newtons per square meter. When h = 1 meter, P =2.003*10^8 newtons per square meter. Obtain the equation that defines P as a function of h, and use it to find the pressure at a depth of h = 100 meters. What does the slope of the line represent?
Suppose the supply curve for a product is given by the following linear function: p = 5x + 125
a) Estimate the supply if the price of the product is $210.
b) Explain what 125 means in terms of the price and supply of the product.
