It could either be B or C. There is not enough information to tell which one.
Answer:
The answer is: The slope is 1/3.
Step-by-step explanation:
The given points are (-1, 4) and (5, 2)
The equation for slope is the rise over the run:
m = (y - y1) / (x - x1)
m = (4 - 2) / ( -1 - 5)
m = 2/6
m = 1/3
Let P(x,y) be a point on the parabola. The definition of a parabola is the squared distance from P to focus F(2,2) equals the squared distance to the directrix x=8.
squared distance from P(x,y) to focus F(2,2)
(x - 2)² + (y - 2)²
squared distance from P(x,y) to the directrix x=8.
(x-8)²
Those are equal in a parabola,
(x - 2)² + (y - 2)² = (x-8)²
x² - 4x + 4 + y² - 4y + 4 = x² - 16x + 64
y² - 4y - 46 = -12x
That's a sideways parabola,
x = -(y² - 4y - 46)/12
Answer:
Answer is 39.5
Step-by-step explanation:
firstly 7x+19=-79 so we divide-2x from -79 will give positive 39.5
The angle of elevation : α
tan α = 9/13
tan α = 0.6923
α = tan^(-1) 0.6923
α = 34.69° ≈ 35°
Answer: the angle is 35°
