If you have any questions about the way I solved it, don't hesitate to ask me in the comments below =)
We are given with:
Average height of plants to be at least 73 inches
Three plants with heights of
70, 71, 72
The inequality that can be used to determine the possible heights of the fourth plant is:
(70 + 71 + 72 + x) / 4 ≥ 73
Solving for x
x ≥ 79
The dot product will have you multiply the corresponding coordinates and add up the products
v dot w = (6*(-7)) + (7*5) + (-3*2)
v dot w = -42 + 35 - 6
v dot w = -7 - 6
v dot w = -13
Answer: -13
