You are working with the Cosine of the angle.
Hypotenuse = 12.5
Base = 3
Theta = ?
Solution
Cos(theta) = base / hypotenuse Substitute values
Cos(theta) = 3 / 12.5 Divide
Cos(theta) = 0.24 Tale the inverse cos
theta = cos-1(0.24)
theta = 76.11 degrees
Answer:
6k+234
Step-by-Step Explanation:
Add 9, 3, 212, 3, and 7. You get 234. You can't change 6k because the variable, so you end up with 6k+234.
Answer:
Upstream - 2 miles per hour
Downstream - 3 miles per hour
Step-by-step explanation:
For the speed upstream, the answer would be 2 miles per hour (mph), because 6÷3=2.
For the speed downstream, the answer would be 3 miles per hour (mph), because 6÷2=3.
Both answers come in similar methods. Hope this helps you!

Answer:
D. 20
Step-by-step explanation:
First, we need to plug in -2 to all the spots where x are. The new equation we have then is f(-2)= 2(-2)^2 - 3(-2) + 6. Then, we plug in the exponent to get 2(4) - 3(-2) + 6. We can then multiply to get 8 + 6 (since the three was negative as well) + 6, which equals 20.
