Help In the figure shown, L is the center of the circle and PQ is a chord of the circle measuring 20 cm.

What is the length, in cm, of PL? Round to the nearest hundredth digit.

Show me:

(a) length of segment PM (1 point)

(b) what circle property did you use to find the length of PM (1 point)

(c) what formula/theorem did you use to calculate the length of segment PL (1 point)

(d) all math used to calculate the length of segment PL (1 point)

Round your answer to the nearest hundredth digit.

If f(x) = 3x2 - 2x+4 and g(x) = 5x + 6x - 8, find (f-g)(x).

I've been working on this for a few days and i just don't understand, it's due in a few hours. you.the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case.part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
