Answer:
8
Step-by-step explanation:
The equation of the parabola can be represented as

for some constant a.
Since the coefficient of x² is 2, a = 2, so

So, the answer is 8.
Answer:
A.
Step-by-step explanation:
In the attached file
The terminal point represented by P(x,y), is the coordinate where a certain point lies. Given is 5pi/4 radians - this will be our angle.
Evaluate the values of x and y using sin θ and cos θ
x = cos (5pi/4)
x = -√2/2
y = sin (5pi/4)
y = -√2/2
Therefore, (x,y) is (-√2/2, -√2/2)
The answer is D because I took the test
