1. A trapezoidal shaped park is built on a slight incline. The function for the ground elevation above sea level is

f (x, y)= x - 3y + 20 feet. What are the coordinates of the HIGHEST point in the park? (+2 points)

What are the coordinates of the HIGHEST (maximum) point and what is the value of the function at that point?

Highest point (maximum):

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.

contact me if you have any questions you are welcome.

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.

wait this depends wether emily and zach how they are thinking.

yes they are the same.
