Answer:
35.6
Step-by-step explanation:
cos = adj/ hypt
cos (77) = 8/x
x = 8/cos (77) = 35.56
2x - 2y = -4
-3x -3y = 0
_____________________
-1x - 5y = -4
The answer is 10 because it’s multiplies by 10
Answer is number one. The number inside the bracket is the time and the number after the equal sign is the height. As you can see, at t=5, height=75.
Answer: -3√5 + 10√3
Step 1: Find the prime factorization of the number inside the radical.
Step 2: Determine the index of the radical. In this case, the index is two because it is a square root, which means we need two of a kind.
Step 3: Move each group of numbers or variables from inside the radical to outside the radical. In this case, the pair of 2’s and 3’s moved outside the radical.
Step 4: Simplify the expressions both inside and outside the radical by multiplying.
