Apole is held vertically by attaching wires at a height of 13.4 m above the ground. the other end of each wire is anchored in the ground at a distnace of 9.54 m from the base of the pole. the pole makes a right angle with the ground. what is the length of each wire? b) 3 forces pull in different directions on an object at the origin. once force has a magnitude of 100 newtons, and pulls at an angle 140 degrees with respect to the +x axis. the other two forces are 200 newtons at an angle of 70 degrees, and 160 newtons at an angle of 250 degress. along what angle (in degress) could a single force of the appropriate magnitude point that would accomlish the same thing as the three factors acting together?

The vector matrix [2/7] is dilated by a favor of 1.5 and then reflected across the x axis. if the resulting matrix is [a/b] then a= and b=

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:

The graph of y = ax^2 + bx + c is a parabola that opens up and has a vertex at (0, 5). what is the solution set of the related equation 0 = ax%2 + bx + c?
