Working together, Fred and Laura can finish their history project in 3 hours. Had Laura done it
alone, it would have taken her 4 hours. Find out
how long it would take Fred to do the project
alone.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

The answer is a. point

Ibelieve the answer is pollen contains the sperm cell because the flower only has female parts and the pollen is the male part of the flower i believe
