A power plant sits next to a river where the riveris 800 ft wide. To lay a new cable from the plant to a location inthe city 2 mi downstream on the opposite side costs $180 per footacross the river and $100 per foot along the land. Suppose that the cable goes from the plant to a point Q on the opposite side that is x ft from the point P directly opposite the plant. Write a function C(x) that gives the cost of laying the cable in terms of the distance x.
Quadratic Equation
When it comes to the concept of polynomial equations, quadratic equations can be said to be a special case. What does solving a quadratic equation mean? We will understand the quadratics and their types once we are familiar with the polynomial equations and their types.
Demand and Supply Function
The concept of demand and supply is important for various factors. One of them is studying and evaluating the condition of an economy within a given period of time. The analysis or evaluation of the demand side factors are important for the suppliers to understand the consumer behavior. The evaluation of supply side factors is important for the consumers in order to understand that what kind of combination of goods or what kind of goods and services he or she should consume in order to maximize his utility and minimize the cost. Therefore, in microeconomics both of these concepts are extremely important in order to have an idea that what exactly is going on in the economy.
A power plant sits next to a river where the river
is 800 ft wide. To lay a new cable from the plant to a location in
the city 2 mi downstream on the opposite side costs $180 per foot
across the river and $100 per foot along the land. Suppose that the cable goes from the plant to a point Q on
the opposite side that is x ft from the point P directly opposite
the plant. Write a function C(x) that gives the cost of laying the
cable in terms of the distance x.
