Lab Activity Interact with the virtual laboratory to create an electromagnet to pick up paperclips.
Notice that there are many variables to test in this lab:
different types of material,
• different gauges or thicknesses of wire,
• number of winds around the iron bar,
the voltage
.
.
→ Open the lab interactive and run a few trials changing the variables each time. Decide|
which variable you want to change in order to make a strong electromagnet and record it
here.
Hypothesis (5 points)
Record your hypothesis as an "if, then" statement.
(If the independent variable does this, then the dependent variable will do that)

The second largest public utility in the nation is the sole provider of electricity in 32 counties of southern florida. to meet the monthly demand for electricity in these counties, which is given by the inverse demand function p = 1,200 – 4q, the utility company has set up two electric generating facilities: q1 kilowatts are produced at facility 1, and q2 kilowatts are produced at facility 2 (so q = q1 + q2). the costs of producing electricity at each facility are given by c1(q1) = 8,000 + 6q12 and c2(q2) = 6,000 + 3q22, respectively. determine the profit-maximizing amounts of electricity to produce at the two facilities, the optimal price, and the utility company’s profit
