Find the standard form of the equation of the parabola with a focus at (-4, 0) and a directrix at x = 4.
Answer:
0
Step-by-step explanation:
No matter what value of x you input into this equation, you will get a y value of 3. This means that over infinite run, the line has no rise, and therefore has slope of 0. Hope this helps!
45 = 3x3x5
Or you could simplify it to 3^2x5
Assuming a normal distribution we find the standardized z scores for a:-
z1 = (80 - 180) / 25 = = -100/25 = -4
z2 = (280-180) / 25 = 4
Required P( -4 < z < 4) from the tables is >99.9%
b
z1 = 130-180 / 25 = -2
z2 = 230-180 / 25 = 2
from tables probability is 2* 0.4773 = 95.46 %
Just reflect C and D across the y-axis
C is (-4, -4) so A is (-4, 4)
D is (4, -4) so B is (4, 4)
