Answer:
Step-by-step explanation:
2.5/8
(5/2) / 8
(5/2) * (1/8)
5/16
via the angle sum formula of sin
which proves the second choice
the third choice is wrong since for x=0,y=0 it will show that 2=1 which is incorrect
for the fourth one you can do some thing similar to choice one just expand the sum formula of sin and that should be true too
so
the first , the second and the fourth are all true
Answer: 6√2
Step-by-step explanation:
8 × 9 is 72.
8 can be simplied to 4 × 2.
And 4 can be simplified to 2 × 2.
So far there are three 2s and a 9.
9 can be simplified down to 3 × 3.
Theres a pair of 2s and a pair of 3s, so you multiply 2 × 3 and thats 6 so you put 6 on the outside of the radical. Theres one 2 leftover from all the simplifying so that goes inside the radical to give you 6√2
Answer:
1/4 × 1/6
Step-by-step explanation:
To turn a fraction division sentence into a multiplication sentence, simply multiply the second fraction by its reciprocal. For example: 1/4 ÷ 6/1 is equaled to 1/4 × 1/6.
I hope this helps!
