2.306
Step-by-step explanation:
Hope this helps and have a great day.
Step-by-step explanation:
Remember the identity sin²x + cos²x = 1.
Therefore 1 - cos²x = sin²x and 1 - sin²x = cos²x.
sqrt(1 - cos²x) / sinx + sqrt(1 - sin²x) / cosx
= sqrt(sin²x) / sinx + sqrt(cos²x) / cosx
= sinx / sinx + cosx / cosx
= 1 + 1

Kaitlin rented 3 video games and 6 dvds.
2.60 x 3 = 7.50 (dollars and cents)
3.30 x 6 = 19.80 (dollars and cents)
add them together to get the total cost in the past month.
(to find the answer you know the price for a single video game/DVD so what you do is multiply those prices times how much they bought)
ex: $2.60 x 3 <-- the amount of games she bought.
i hope this helps you.
