If a ball is thrown vertically upward from the roof of 4848 foot building with a velocity of 6464 ft/sec, its height after tt seconds is s(t)=48+64t−16t^2  What is the maximum height the ball reaches?   What is the velocity of the ball when it hits the ground (height 0)?

If distance in feet of a ball above ground is given by D=224+80t-16t^2 (t measured in seconds), when will the ball hit the ground? (at what value of t)?

solve for A, 1.35=[((1+A)^6-1)/A]

Find the value of n(A) if n(B)=32, n(A^B)=17, and n(AUB)=49.

A body is projected vertically upward such that is height from the ground in feet is h = 50t – 16.1t^2 where t = time in flight in seconds.  After how many seconds will the velocity be 12 fps?

By using equation qx= 2mx/(2+mx) , derive a similar equation for the more general case of an age group of width years (x to x+n years) that is show tha nqx = (2*n* nmx) /(2+n*nmx)

solve 4sin^2x+4coscos(x)-5=0 in the interval (0°, 360°]

Suppose an equilateral triangle has edges of lengths x. As the lengths of the edges increase, the area increases by V .square centimeters per minute. At what rate is = 5 , -- centimeters per minute. Write the length of the edge changing when each edge is 5 centimeters? At the length of each edge is increasing by the number below and round the solution to the nearest ten thousandths of a centimeter.

Suppose a table tennis ball is hit in such a way that it's path can be modeled by h=-4.9t^2+2.07t where h is the height in meters above the table and the is the time in seconds. About how many seconds did it take for the table tennis ball to reach its maximum height after its initial bounce? Round to the nearest tenth.

Find the solution to this equation: z^3=(-1-(sqrt(3))(i))
