Let a = 2 + 4i, b= 14 + 8i, and supose that c is the midpoint of a and b and that is the midpoint of a and c.
a. find points c and
b. find the distance betwen a and b.
c. find the distance betwen a and c.
d. find the distance betwen c and
e. find the distance betwen and b.
f. find a point one-quarter of the way along the line segment conecting segment a and b, closer to a than to b.
g. terence thinks the distance from b to c is the same as the distance from a to b. is he corect? explain why
or why not.
h. using your answer from part (g), if e is the midpoint of c and b, can you find the distance from e to c?
explain.
i. without doing any more work, can you find point e? explain.

What are the solutions of the equation? 16x^2 + 24x + 5 = 5 a. 1/4, 5/4 b. -1/4, -5/4 c. -1/4, 5/4 d. 1/4 , -5/4

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks. for more details, view how to split a stem.) minutes beyond 2 hours earlier period 0 1 2 (b) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the recent period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks.) minutes beyond 2 hours recent period (c) compare the two distributions. how many times under 15 minutes are in each distribution

20 ! need ! which exponential function is represented by the table? f(x) = 0.2(0.5x)f(x) = 0.5(5x)f(x) = 0.5(0.2x)f(x) = 0.2(0.2x)
