An apple is launched directly upward at 64 feet per second from a platform 80 feet high. The equation for this apple's height h at time t seconds after launch
is h(t) = -16t? + 64t + 80. How many seconds until the apple is 100 feet high?

0.34

Step-by-step explanation:

you can type this into the calculator too and by going to your table settings you can adjust where it"ll reach 100 or do 100=-16t^2+64t+80 and solve

sorry I am not good at quick maths so I cant do it in my head

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.
