3. A rocket is launched vertically from the ground with an initial velocity of 64 . (a) Write a quadratic function that shows the height, in feet, of the rocket t seconds after it was launched. (b) Determine the rocket’s maximum height, the amount of time it took to reach its maximum height, and the amount of time it was in the air. Show work for all steps. (c) Graph on the coordinate plane using important information from part b.

The perimeter of a stage is 116 feet. it is 17 feet wide. how long is it?

The trigonometric ratios sine and secant are reciprocals of each other

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 b suppose 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 c now try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
