You need it to be an equation rather than an expression to find any kind of answer
Step-by-step explanation:
sin(2x) + cos(3x)
Use double angle formula sin(2x) = 2 sin x cos x.
Use triple angle formula cos(3x) = 4 cos³x − 3 cos x.
Substitute:
2 sin x cos x + 4 cos³x − 3 cos x
Answer:
=15.5
Step-by-step explanation:
1/2b x h
12b x 10=155
12b=155/10=31/2
b=31/2 divided by 12
=15.5
The next ten numbers will be 20,18,36,34,68,66,132,130,260,258. Hope this helps.
40,000 divided by 20 equals 2,000. 8 times 2,000 equals 16,000 so 16,000 out of 40,000 students would be absent from school less than five days a year.
