Answer:
Step-by-step explanation:
we know that distance d from the focus to P should be the same to the distance from P to the directrix
(x-h)^2=4p(y-k)
we need to find the y coordinate,
x is the same from focus, 3
y=(3, (4+2)/2)=(3,3)
we find p now by subtracting the y from the focus from the y that we just found
p=4-3=1
again (x-h)^2=4p(y-k), p=1
(x-3)^2=4(1)(y-3)
(x-3)^2=4(y-3), (x-3)^2=4y-12
simplify
4y=(x-3)^2+12
y=((x-3)^2)/4 + 3
Answer:
it will take 10 weeks for him to pay his brother completly
Step-by-step explanation:
Hello!
You find the area of a rectangle by the equation A = lw
A is area
l is length
w is width
Put in the values you know
180 = 3x * 6
Now you solve it algebraically
Divide both sides by 6
30 = 3x
Divide both sides by 3
10 = x
The answer is 10in
Hope this helps!
