Answer:
-1.513888889 = -1.51
Step-by-step explanation:
-5/8 = -0.625
-8/9 = -0.8888888888
-0.625 + -0.8888888888 = -1.513888889
If you round this to the nearest tenth you get
<u>-1.51</u>
Answer:
the vertex of the parabola is:(-2,0)
the focus of the parabola is:(-2,
)
the directrix of the parabola is:y=
Step-by-step explanation:
we know that for any general equation of the parabola of the type 
the vertex of the parabola is given by (h,k)
where 
and 
therefore by the given data we have h=-2 and k=0
hence vertex=(-2,0)
the general equation of the parabola of the type 
; the parabola symmetric around the y-axis has the focus from the centre i.e. the vertex (h,k) at a distance a as (h,k+a) and the directrix is given by y=k-a
so focus is 
now the directrix of the parabola is 
.
Let s = number of student tickets and a = number of adult tichets;
We have the equation: s + a = 559 and s = 59 + a;
Then, we solve the equation: 59 + a + a = 559;
59 + 2a = 559;
2a = 500;
a = 500/2;
a = 250;
s = 59 + 250;
s = 309;
