Answer: 8 inches
Step-by-step explanation: So you know that to get the circumference of a circle is 2πr, right? So you divide 16 by 2 to get your radius. So that's how you 8 inches.
Tan(θ) = 3 tan(θ), 0° ≤ θ ≤ 360°
Solve for θ to the nearest degree.
tan(θ) = 3 tan(θ)
Subtract tan(θ) from both sides:
0 = 2 tan(θ)
Divide by 2 both sides:
tan(θ) = 0
If (x,y) is a point on the terminal ray of θ,
then tan(θ) = y/x = 0, and y = 0.
y = 0 ==> θ = 0°, 180°, or 360° in the interval 0° ≤ θ ≤ 360°.
With
a standard deviation of 6 minutes, we will test the hypothesis that σ = 6
against the alternative that σ < 6 if a random sample of the test
times of 20 high school seniors has a standard deviation s = 4.51. use a
0.05 level of significance.

Step-by-step explanation:
Let's combine the like terms first, which are x^2 & -3x^2, and 3x & -4x.
x^2 -3x^2 is -2x^2. 3x -4x is -x.
The final, simplified expression would be -2x^2 -x.
