The standard equation is 4p(x-h) = (y-k)^2 where |p| = focal distance |4p| = focal width.
<span>x=-1/8y^2
-8x=y^2
4*(-2)(x-0) =( y-0)^2
p = -2, h=0, k=0</span><span>
focal width = |4*(-2)| = 8
The answer to your question is that the length of the focal width is equal to 8.</span>
(-5, 2) ⇒ x₁ = -5, y₁ = 2
(7, -1) ⇒ x₂ = 7, y₂ = -1
Slope:
Slope intercept form:
y = mx + b
Plug <em>m</em> and (7, -1) :
-1 = -¹/₄(7) + b
-1 + ⁷/₄ = b
<h3>b = ³/₄ ← y-intercept</h3>
Therefore slope intercept form of h(x):
<h3>h(x) = -¹/₄x + ³/₄</h3>
Answer:
No there cannot be.
Step-by-step explanation:
In explaining this question, I would like us to take into account who the barber is,
" the barber is the one who shaves all those, and those only, who do not shave themselves".
This barber cannot be in existence because who would shave him? If he should shave himself then there is a violation of the rule which says he shaves only those who do not shave themselves. If he shaves himself then he ceases to be a barber. And if he does not shave himself then he happens to be under those who must be shaved by the barber, because of what the rule says. But then he is the barber.
This lead us to a contradiction.
Neither is possible so there is no such barber.
Its A
7x+7= 112
7x= 112-7
7x=105
x=105/7
x=15
To find y
180-112=68
68/4 =17
x= 15 y=17
