An object is launched vertically in the air at 31.85 meters per second from a 9 -meter-tall platform. Using the projectile motion model h left parenthesis t right parenthesis equals negative 4.9 t squared plus v 0 t plus h 0 comma where h(t) is the height of the projectile t seconds after its departure, v 0 is the initial velocity in meters per second, and h 0 is the initial height in meters, determine how long it will take for the object to reach its maximum height. What is the maximum height?

unless if u could do my questions, if not i wouldn't want to

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
