In American football, the ball is punted by dropping and kicking it before it hits the ground. The height h(t) of the football above the ground in meters t
seconds after being punted is affected by gravity and by the punter's kick,
and can be represented as the difference of two functions: a (t) = 4.2t?,
which specifies the effect of gravity on the height of the ball, and v (t) = 16.5t + 2, which specifies the effect of the punt on the ball.
With these two functions, h(t) = v(t) - a (t), how high above the ground was the ball when it was punted?

Divide. write in simplest form 41/6 divided by 10

The high temp today was 62°. when nighttime comes, the temp will drop 40°. by 4am the temp will drop an additional 40°. what is the temp at 4am?

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 > ?
