You’ve explored a variety of trigonometric applications and studied different coordinate systems in the process, namely the Cartesian (rectangular), the polar, and the complex coordinate systems. What do these coordinate systems have in common, and how is each system unique? How is the absolute value of an imaginary number, the magnitude of a force, and the distance between two points related to one another? What are the advantages and disadvantages of each system?

answer: a

step-by-step explanation:

10.2 units

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

you divide them and then you get the answer i took this class this year
