Answer:
C
Step-by-step explanation:
The difference formula for cosine is
cos(x - y) = cosxcosy + sinxsiny
Consider
cos75 = cos(120 - 45)°, then
cos(120 - 45)°
= cos120°cos45° + sin120°sin45° → C
Answer:
10
Step-by-step explanation:
Differentiate each term with respect to x , then solve y'.
dy/dx = y+2x^3/ x(1+x)
Tigers: 1 - 2/3 = .3333
Redbirds: 1 - 4/5 = .2
Bulldogs: 1 - 3/8 = .625
Titans: 1 - 1/2 = .5
The Redbirds likelyhood is lowest, therefore, they're least likely to play I'm the championship.
B is the correct answer.
First, divide the shape into two figures ( a semicircle and a rectangle)
Then, find the are or the two shapes using the area formula for a semicircle (

) and the are formula for a rectangle (base x height)
Finally, add the two areas together and you have your answer
