The height in feet of an object projected upward as a function of the elapsed time in seconds since it was launched can be represented by the formula shown below. h(t) = –16t2 + v0t + h0 In the formula h(t) is height in feet; t is time in seconds; v0 is the initial velocity; and h0 is the initial height. An object is projected upward with an initial velocity of 50 feet per second from a starting height of 9 feet. When will the object hit the ground?

Find the solutions for a triangle with a =16, c =12, and b = 63º

What is the 17th term in the arithmetic sequence in which a6 is 101 and a9 is 83

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 > ?
