Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
• tanx = 
• sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x
Consider the left side
= 
- 
= 1 - cos²x
= sin²x = right side ⇒ verified
Answer:
Step-by-step explanation:
We can subtract a term from another if they have the same variable. Both 
and 
have the variable 
, so we can subtract them.
When subtracting these terms, we subtract the coefficients and keep the variable.
So:

Answer:
C. 11 is the correct answer
Step-by-step explanation:
The table representing the probabilities of player's batting average is,
Left-Handed pitchers Right-Handed pitchers
Bats Left 0.285 0.175
Bats Right 0.215 0.250
So, when the players bats left 100 times,
The probability of hits he gets when faced by left-handed pitchers = 0.285 × 100 = 28.5
The probability of hits he gets when faced by right-handed pitchers = 0.175 × 100 = 17.5
Thus, the difference in the hits = 28.5 - 17.5 = 11
Hence, the player will get 11 more hits t when he faces left-handed pitchers as opposed to right-handed pitchers.
