Answer: 84.8°
Step-by-step explanation:
a²+b²+c²-2bc(cosA)
cosA = b² + c² - a² / 2bc
That is the formula we will be using.
Then, plug in our numbers.
cosP= 500² + 380² - 600² / 2(500)(380)
cosP= 34400/380000
cosP≈ 0.09052631
cos⁻¹(0.09052631) ≈ 84.81
∠P = 84.8°

Answer:
The correct answer is B) y = 2x - 1
Step-by-step explanation:
To find this, first choose any two data points and find the slope. We'll use points (-2, -3) and (0, 1)
m(slope) = (y2 - y1)/(x2 -x1)
m = (1 - -3)/(0 - -2)
m = 4/2
m = 2
Now we use either point and the slope in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 1 = 2(x - 0)
y - 1 = 2x
y = 2x + 1
