Answer:
c
Step-by-step explanation:
The chances would be 1/5 because you already had landed on 6
The correct unit price would be $1.08 per pair of gloves. What the contractor didn't notice was it was 7 <em>dozen</em> pairs of gloves, not just seven pairs. If it had been seven pairs, she would have been correct, but it was actually 84 pairs of gloves. She needed to divide 103.32 by 84 rather than 7.
Answer:
-1
Step-by-step explanation:
To solve this without L'Hopital's rule, multiply by the conjugate, (1 − cos n + sin n) / (1 − cos n + sin n).
The numerator becomes:
(1 − cos n + sin n) (1 − cos n + sin n)
(1 − cos n + sin n) − cos n (1 − cos n + sin n) + sin n (1 − cos n + sin n)
1 − cos n + sin n − cos n + cos² n − sin n cos n + sin n − sin n cos n + sin² n
2 − 2 cos n + 2 sin n − 2 sin n cos n
2 − 2 cos n + sin n (2 − 2 cos n)
(1 + sin n) (2 − 2 cos n)
The denominator becomes:
(1 − cos n − sin n) (1 − cos n + sin n)
(1 − cos n)² − sin² n
1 − 2 cos n + cos² n − sin² n
1 − 2 cos n + cos² n − 1 + cos² n
2 cos² n − 2 cos n
-cos n (2 − 2 cos n)
Dividing, the 2 − 2 cos n factors cancel out, leaving us with:
(1 + sin n) / -cos n
The limit as n approaches 0 is therefore:
(1 + 0) / -1
-1
