Convert to vertex form:-
= -0.04(x^2 + 39x)
= -0.04( (x + 19.5)^2 - 380.25)
vertex is at -0.04 * -380.25 = 15.21 yards
Maximum height is about 15.2 yards
Answer:
Step-by-step explanation:
17x + 14 + 4x -2 = 21x + 12
21x + 12 = 180
-12 -12
21x = 168
x = 8 degrees
Answer: x = r + s
Step-by-step explanation:
Try to get x to one side and everything else on the other side.
r = s - x ( add a to both sides)
r + s = s - s - x
r + s = x
Add up the totals before tax:
1860 + 5775 = 7635
Find 8.2% of this:
0.082 * 7635 = 626.07
Now add this on to it:
7635 + 626.07 = 8261.07
So the total cost is $8,261.07
