The exact value.tan-1(-1) = -45 degrees
or
360 - 45 = 315 degrees

Answer:
.
Step-by-step explanation:
Let C represent total daily charges in dollars and t represent time in hours.
We have been given that a plumber charges $50 for a service call plus $80 per hour.
The amount charged for t hours would be
.
The total amount charged for t hours would be
.
We are also told that plumber spends no longer than 8 hours a day at any one site, this means that time t have a restriction as:

Therefore, our required cost function would be
.
To find the answer, use pythagorean theorum (a^2 + b^2 = c^2)
We'll square a and c, and then subtract a from c.
9 + b^2 = 361
361 - 9 = 352
The square root of 352 is 18.7
18.7 should be the correct answer.
False
lets say u have 2 sets of points (1,2) , (3,4)
now lets say (1,2) is (x1,y1) and (3,4) is (x2,y2)
slope = (y2 - y1) / (x2 - x1)
slope = (4-2) / (3-1) = 2/2 = 1
now, lets say (1,2) is (x2,y2) and (3,4) is (x1,y1)
slope = (y2 - y1) / (x2 - x1)
slope = (2 - 4) / (1 - 3) = -2/-2 = 1
in conclusion, the naming of the points will not effect the slope
