Answer:
(-1, -1)
Step-by-step explanation:
One way to write the relationship between the x and y coordinates and θ is ...
tan(θ) = y/x
Then ...
y = x·tan(θ) = -1·tan(-3π/4) = -1·1
y = -1
The coordinates of the point on the terminal side are (x, y) = (-1, -1).
Answer:
2, 2, 4, 8, 14, 22, 32, 44
Answer:
x=6
Step-by-step explanation:
9(8-x)=3x
9 x 8=72
72-9x=3x
72=12x
72/12=6
x=6
Answer: √731 ≈ 27.03701167
Use Pythagorean theorem to find this answer
a² + b² = c²
Let's say 13 is a and 30 is c
13² + b² = 30²
This gives you 169 + b² = 900
Subtract 169 from both sides and get b² = 731
Root both sides
√731 is already in the simplest form so that would be your final answer.
