Whether the statement “I noticed that depending on the values for
Aand B assuming that they are not both zero, the graph of
\(Ax^2 + By^2 = C\) can represent any of the conic sections other than a
parabola” “makes sense” or “does not make sense”, And explain
your reasoning.

Sheila is in Ms. Cai's class . She noticed that the graph of the perimeter for the "dented square" in problem 3-61 was a line . "I wonder what the graph of its area looks like ," she said to her teammates .

a. Write an equation for the area of the "dented square" if xx represents the length of the large square and yy represents the area of the square.

b. On graph paper , graph the rule you found for the area in part (a). Why does a 1st−quadrant graph make sense for this situation? Are there other values of xx that cannot work in this situation? Be sure to include an indication of this on your graph, as necessary.

c. Explain to Sheila what the graph of the area looks like.

d. Use the graph to approximate xx when the area of the shape is 20 square units.

There are similarities and differences between solving 4x + 1 = 3 and 4 sin θ + 1 = 3: In the first equation, I need to isolate x to get the solution. In the trigonometric equation, I need to first isolate sin θ, but then I mustcontinue to solve forθ.Determine whether the statement makes sense or does not make sense, and explain your reasoning.

Determine whether each statement makes sense or does not make sense, and explain your reasoning. By modeling attitudes of college freshmen from 1969 through 2010, I can make precise predictions about the attitudes of the freshman class of 2020.
