Construct a graph that shows the diameter of a lens that is needed to obtain a resolution of 1 arc second from far-ultraviolet wavelengths in 100 nm to infared wavelengths of 10 microns. From orbit, a human subtends an angle if 1 arc second and emits infared energy at a wavelength of 10 microns. How large would the camera have to be to resolve a human by his heat emmision?

11/2.2 = 5 inches for the length 8.5/2.2= 3.86 inches for the width

25% increaseplus i think decrease i only know increase: ((

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )

Multiple choice or not?
