circle with a radius r is πr^2 . The area of the circular base is 36π. If the radius of the circular ...
Since point P is on segment SV, the y-coordinate of point P is also 2. Then the y-coordinate of point ...
then the median of the numbers in set S is the average of the two middle terms. Since the two middle terms amon ...
So the standard deviation of the numbers in set T, is 3 times the standard deviation of the numbers in set S ...
Letting n = 3 in the defining equation an = 3an−1 − an−2, you have a 3 = 3a 2 − a 1 = 3(3) ...
until it reaches −1 again at the end of the cycle at x = 2π. The coordinates of the point where y is a ma ...
Line t contains side AB of the triangle. Choice (E) can occur when a line divides an isosceles right ...
15 . A Solve the equation for x. Squaring both sides, . So x = 7(2.74^2 ). Using the calculator, x ≈ ...
30 x−5+6y^12 z−8 = 10 x−6+6y^5 z^4 , and 30 xy^12 z−8 = 10 y^5 z^4 . Dividing both sides by 30y^12 z−8, you ...
