Answer:
True; quadrants I & IV
Step-by-step explanation:
We know the relation between sine and cosine function which is given by

Let us solve this equation for cosine function.

Take square root both sides. When ever we take square root we need to write the solution in plus minus form



If Θ is in quadrants I and IV then the value will be positive and if Θ is in II and III quadrant then the value is negative.
Hence, if Θ is in quadrants I & IV, then we have

Thus, the correct option is: True; quadrants I & IV

Answer:
Number of miles is either less than 8255.25 or greater than 17255.25.
Step-by-step explanation:
Given that :
Difference in mileage of the sedan and minivan is > 4500
Mikeage of minivan = 12755.25
Possible number of miles on the sedan :
Mileage on minvan ± difference in mileage ;
12755.25 ± 4500
12755.25 + 4500 = 17255.25
12755.25 - 4500 = 8255.25
This means that the possible number of miles on the sedan is either greater than 17255.25 OR less Than 8255.25
