Answer:
You would use B. 1239 times .0625
Step-by-step explanation:
I am assuming the computer costs 1239. Since percent means 'per hundred' you first need to convert percent into decimals. You would divide 6.25 by 100, giving you .0625. Multiplying the computer price and this decimal will give you the discount price.

Step-by-step explanation:
cos 2x + 2 sin²x
= (1 - 2 sin²x) + 2 sin²x
= 1 - 2 sin²x + 2 sin²x
= 1
Answer:
12
Step-by-step explanation:
For these problems you should use the pythagorean theorem: a^2+b^2=c^2
In this case, 13=c and 5=a
so:
5^2+x^2=13^2
25+x^2=169
subtract 25 from both sides
x^2=144
√144=12
missing side=12
Answer:
80, 100
