25 points and brainliest! I need help with this whole thing ASAP! this is due TODAY. questions are in the picture.

Step-by-step explanation:

Use a calculator for the first 3 questions:

2. sin (12) = 0.207911691

3. cos (78) = 0.207911691

4. tan (4) = 0.069926812

5. tangent = opposite side / adjacent side

   tan (A) =

6. cosine = adjacent side / hypotenuse

   cos (A) =

7. sine = opposite side / hypotenuse

  sin (A) =

Hope that helps!

i can you with this sweetie!

step-by-step explanation:

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y
