2/12 or 1/6. You have to divide 2/3 by 4 to get what w equals to.
Answer:
Step-by-step explanation:
y=x²+7
vertex(0,7)
the length of latus rectum in a parabola equal to four times the focal length :
y=x²+7
focus X=-b/2a=0
focus Y=c- (b²-1)/4a=7+1/4=29/4
focus (0 , 29/4)
latus rectum is 29/4
(x-h)^2 = 4p (y-k) 4p is the length of the latus rectum with vertex(0,7)
(0-0)²=4p(29/4-7)
0=29p-28p=1p
the length of the latus rectum is 1
P = 4r + 3t
4r = p - 3t
r = (p - 3t)/4
Answer: x = -0.58
Step-by-step explanation:
-3x+2-5x-7=4x+2
First step, collect like terms
-3x -5x-4x = 2-2+7
-12x = 7
x = 7/-12
x = -0.58
Base = 5
height = 12
Area = (5*12)/2 = 30 m²
