Answer:
A and B
Step-by-step explanation:
1) Distance to the focus
From (x,y) to the focus(2,-4) {using distance formula}
=√(x-2)²+(y+4)²
2) Distance to the directrix
Is, y+p where P here is (-6)
So
d2 = y+p
= y+(-6)
= y-6
Answer: x = 2.8283
Step-by-step explanation:
pythagorean theory or sohcahtoa or sin law
T = 60' and T = 45': S = 90' : T = 45' : R = 90'
t = 3.464
sin law (i can't rlly show u)
q = 3.99
if u don't know what q is, it is the length of the middle line also known as RT
then u do
180 - 45 - 90 = Q
45 = Q
with 45 we can do sin law again
x = 2.8283 is the length of x
Answer:
Algebra is math, like X, Y and all that.
Step-by-step explanation:
X = 3.....................
10 trees / 2 hours = 5 trees per hour
150 trees / 5 per hour = 30 hours
