I think your answer would be 4,000
Answer:
14
Step-by-step explanation:
Think how many times does 6 go into 84.
you can divide 84 into 6 which is 14.
Or you can think what times 6 equals 84.
This seems disgusting to solve directly, so let's convert this to vertex form.
1) Divide all terms by 1/2:
2y = -x² - 4x + 14
2) Complete the square:
2y = -(x² + 4x - 14)
2y = -(x² + 4x + 4 - 4 - 14)
2y = -[(x + 2)² - 18]
2y = -(x + 2)² + 18
3) Rewrite in vertex form:
(x + 2)² = -2y + 18
(x + 2)² = -2(y - 9)
Now, we know the vertex is at (-2, 9)
It's a concave down parabola
The axis of symmetry is simply the x-ordinate of the vertex.
The focus is at (-2, 17/2)
The directrix is at (-2, 19/2)
The y-intercept is at y = 7
Answer:
31.93
Step-by-step explanation:
you prob just want the answer but here
1. Find 40% of 72.29 (29.16)
2. find 9.5% of 29.16 that would be $2.77
3. add $2.77 to 29.16
