First convert 6 miles to yards. That would be 10,560 next divde it by 350 to get 30.1786 but you have to round it to the next lap. Therfore, youll have to run a total of 31 laps around the field.
Patterns: vertical : y = a(x - h)² + k horizontal: x = a(y - k)² + h
Look at the patterns above and remember these key points.
<span>1) if the x is squared, the parabola is vertical. It either opens up or down. </span>
if the y is squared, the parabola is horizontal. It either opens left or right.
2) if a is positive, the parabola opens up or to the right.
if a is negative, the parabola opens down or to the left
<span>3) the vertex is at (h,k). Be very careful. locations of h and k varies if the parabola is vertical or horizontal. its sign is also different in those positions</span>
Answer:
Maybe the figure of this question is a triangle.
If so...the answer comes something like this....
Hope it helps! :)
We know, a number is divisible by 9 if the sum of digits is also divisible by 9.
Also, since A is an digit, so A is in between 0 to 9.
2+A+5+A+0+A+2 = 3A + 9
3A + 9 should be divisible by 9.
3A + 9 = 9n
A = (9n -9)/3
For n= 1 :
A = 0
For n=2 :
A = 3
For n= 3 :
A = 9
After this A > 9 which is not accepted.
Therefore, the digit A can be 0, 3 and 9 .
Hence, this is the required solution.
