The equation of the parabola with vertex (h,k)(h,k) is y=a(−h+x)^2+ky=a(−h+x)^2+k.

Thus, the equation of the parabola is y=a(x+3)^2+1y=a(x+3)^2+1.

To find a, use the fact that the parabola passes through the point (−2,4)(−2,4): 4=a+14=a+1.

Solving this equation, we get that a=3a=3.

Thus, the equation of the parabola is y=3(x+3)2+1y=3(x+3)^2+1.

I think you're 1 off, 441 is NOT divisible by 11, you would get 1 mod(11) if you add 4.

If we visualive the diagram as a quadrilateral  with the sum of its angles at 360 degress we can solve this problem. Because the line that you reflect things on would have to be perpendicular to the point, we know that two angles would be 90 degress. We also know a third angle is 34 degress so all we need to do is subtract 2*90+34 from 360 to get 146 degrees as your answer.

Hope it helps!

The base 6 number when converted to base 10 is 437+42d. From here, we try the numbers 1-5 to see what makes it a multiple of 11 and we get 3 as your answer.

Hope it helps!

Since the balls are the same and the boxes are the same, the problem is basically how many ways can you get a sum of 4.

1+1+1+1

1+1+2

2+2

3+1

4

I get 5 ways.

Ok, new answer... 1/(5^2) has a pattern where the digits to the right of the decimal place are powers of 2. 2, 4, 8, 16, 32... and so on. Finding the sum of these digits we get 2=2, 4=4, 8=8, 1+6=7, 3+2=5, 6+4=10, and 1+2+8=11. 128 is 2^7 so your answer is 7.

Hope it helps!

I thought it was, but please let me see if I can fix this answer.

Edit: I realize that I did the number of digits and not the sum of the digits, please let me fix this. Thanks!

I think you are missing a number next to the exponent sign next to the 9x.

9x^missing number here-5x^3-8x^2+8x-8

I'm pretty sure it's a 4 which makes your answer 538. If the missing number is NOT 4 then please fix the question.

The circumference of the tire would be pi*diameter= pi*62= 62pi. Since there are 10 full revolutions, that means you answer is 10*62pi= 620pi centimeters.

Hope it helps!
