Can you double a square with a straightedge and a compass?

I'd say yes. If you use the diagonal as a reference. Take the square and set your compass to the width of the diameter of the square. Now put it on the page and mark a point. Put the point of the compass on that mark and make another mark. Now you can connect the two marks with the straight edge and you have a line that, if you made a square with sides that long, it'd have 2x the area of the first one. That's because the diagonal is the square root of 2 larger than one side. Square the square root of 2 and you've got 2. You lust need to make a perpendicular line to the first one to get the box going.

Divide 3 by 8 (the fraction): 3/8=.375. Make into a percent: 37.5% or 38% (depending on what your teacher wants) and that's your answer :)

Which of these is an exponential parent function? A. f(x) = 2^x – 3 B. f(x) = 2^x + 2 C. f(x) = 2^x D. f(x) = 2^x + 1/3

An exponential parent function is the option C. f(x)= $2^{x}$ , from the given options.

What do you mean by exponential parent function?

The formula for their parent function is y = $b^{x}$ , where b is any non zero constant. Below is a graph of the parent function, y = $e^{x}$ , which demonstrates that it will never equal 0. And at y = 1 when x = 0, y crosses the y-axis.
