Afire truck is en route to an address that is six blocks east and five blocks north of the fire station. using the fire station as the pole and the east direction as the polar axis, express the fire truck's destination in polar coordinates. round the coordinates to the nearest hundredth. express θ in degrees.

(We have to assume the blocks are square.) The Pythagorean theorem gives the radial distance (d).
  d = √(6² + 5²) = √61 ≈ 7.81 . . . blocks

The tangent of the angle (θ) is the ratio of northerly distance to easterly distance.
  tan(θ) = 5/6
  θ = arctan(5/6) ≈ 39.81°

The polar coordinates of the address are 7.81∠39.81°.

The answer is 10 bud

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 : )
