H=-16t^2+-(304)/2(-16) How long does it take the projectile to reach its maximum height. Use the vertex formula to determine the time it takes the projectile to reach its maximum height.

Part 3 find the time it takes the projectile to return to the ground. Assume that the projectile starts at height H=0

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
