Answer:
B. 17
Step-by-step explanation:
The question requires substitution skills.
When given the expression "5+y+8" and "y=4", evaluating the expression would be substituting "y=4" into "5+y+8" which gives you "5+4+8".
From there, you equate the expression and you will obtain "5+4+8=17".
Answer:
D) b/a
Step-by-step explanation:
From the given figure, O = (0, 0) and A = (a, b)
Slope of OA = (y2 - y1) / (x2 - x1)
Here x1 = 0, y1 = 0, x2 = a and y2 = b.
Slope of OA = (b - 0)/(a - 0)
Slope of OA = b/a
Answer: D) b/a

ANSWER
EXPLANATION
We want to find the equation of the parabola with a focus at (5, 0)
and a directrix at x = -5.
The distance from the focus to the vertex is the same as the distance from the vertex to the directrix.
This implies that the parabola has its vertex at the origin. This distance is
This parabola has equation of the form
We plug in p= 5 to get
Or
