In simplest form it should be 5/7
Answer:
8m/s
Step-by-step explanation:
The formula to calculate the average velocity would be
V=meters/second
in this case we have that
V=400m/50s = 8m/s
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
9/8 + 9/4 = 27/8.
Multiply 9/4 by 2.
9/4 • 2 = 18/8
Then, add the fractions.
9/8 + 18/8 = 27/8
Simplify 27/8.
27/8 = 3 3/8
