Answer:
Step-by-step explanation:
The standard equation of a parabola is
y² = 4ax
where, a is the focus,
The coordinates of the centre of parabola is (0,0)
coordinates of focus is (a, 0)
It is symmteric about the x axis
the equation of directrix is x = -a.
Answer: (-5,0)
Step-by-step explanation:
-4x + 5y = 20 the x intercept is when y is zero so input zero into the equation and solve for x.
-4x + 5(0) = 20
-4x = 20
x = -5
Answer:
2/3 would be equal to 4/6, not 5/6.4/5 can't be equivalent to 2/3 either.
Step-by-step explanation:
Alright so here it is
325/50=6.5
6.5*2=13
It would take 13 millimeters of sunscreen to cover 325 cm of skin
159mi/3hr = 53 mi/hr. Hope this helps
