Answer:
(0,0)
Step-by-step explanation:
the x coordinate for the vertex is at the line of symmetry
ax^2 +bx+c
the line of symmetry is at h =-b/2a
x^2 =12y
divide by 12
1/12 x^2 = y
a = 1/12 b=0 c=0
h = 0/(2* 1/12)
h =0
to find the y coordinate, substitute x=0 back in
y = 1/12 * 0 = 0
the vertex is (0,0)
Answer: she paid $1.71 in sales tax.
Find 9 percent of 19 to find the sale tax.
9% of 19 =
0.09 * 19 = 1.71
This means she paid $1.71 in sales tax.
Sn = n/2[2a + (n-1)d]
n=11
a=2
d=3
Sn= 11/2[2(2) + (11-1)3]
Sn= 11/2(34)
Sn = 11x17
=187.
