use the chart below to answer the questions: which of these countries has the greatest population density? which has the least? provide an explanation and proof for your answer to receive full credit.
a = 1/2 * (a + c) * h
a = 1/2 * (6 + (2 + 6 + 2)) * 6 = 48
the given expression is
we split the middle term to obtain;
we factor to obtain;
we factor further to obtain;
well if the angles are complimentary, that means they add up to 90 degrees.
so just do
90 - 52
and you will get
f(x) = height = 64 - 16x^2 = 0.
16x^2 = 64
x^2 = 4
x = 2, -2.
the zero x = 2 means that the height after time 2 is 0. this corresponds to the time of the rock hitting the ground.
the -2 can be ignored.
