The percent p of the american population that graduated from college between 1950 and 1990 is approximately by

p = 5.9556 + 1.492t + 0.0056t^2

where the time t represents the calendar year, with t=0 corresponding to 1950.
using the graph of this model, when will the percent of college graduates exceed 25% of the population?

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.
