Imagine today is your 64th birthday and you decide to retire as of tomorrow morning. you have an annuity that pays you $80,000 per year for as long as you live after retirement, but the payments are not adjusted upward each year to reflect any inflation. if inflation can be expected to average 6% per year, use the rule of 72 to determine how old you will be when the purchasing power of your annuity will have been cut in half,, that is, to the equivalent of only $40,000 today:
answer: p=19.2 ft
by the triangle midsegment theorem, you have:
then, the lengths of the sides of the triangle are:
add them to obtain the perimeter, then you obtain the following result:
p=8 ft+6.4 ft+ 4.8 ft
1/2, line rises
we are given the following pair of points and and we are to find the slope of line passing through these points:
(-1, 3) and (3, 5)
slope = = = =
the slope of this line is 1/2 which is positive so the line rises from bottom left towards top right.
in the given graph, we have a parabola with a small line near it.
the given parabola goes up to a point where x = 2 but fails to reach that value. also, x = 2 starts on the line above where x = 2 and ends right before x = 4.
therefore, the function can be modeled by:
white ball 70 and striped balls 42
for this you have to make proportons that will you a lot
