Answer:
or 15.867 yd
Step-by-step explanation:
![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
![9.9^2+12.4^2=x^2](https://tex.z-dn.net/?f=9.9%5E2%2B12.4%5E2%3Dx%5E2)
![98.01+153.76=x^2](https://tex.z-dn.net/?f=98.01%2B153.76%3Dx%5E2)
![\sqrt{257.77} =x](https://tex.z-dn.net/?f=%5Csqrt%7B257.77%7D%20%3Dx)
15.867 = x
You can find it by integrating twice:
![\displaystyle\int v''(x)\,\mathrm dx=\int(-6x+2)\,\mathrm dx\iff v'(x)=-3x^2+2x+C_1](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cint%20v%27%27%28x%29%5C%2C%5Cmathrm%20dx%3D%5Cint%28-6x%2B2%29%5C%2C%5Cmathrm%20dx%5Ciff%20v%27%28x%29%3D-3x%5E2%2B2x%2BC_1)
![\displaystyle\int v'(x)\,\mathrm dx=\int(-3x^2+2x+C_1)\,\mathrm dx\iff v(x)=-x^3+x^2+C_1x+C_2](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cint%20v%27%28x%29%5C%2C%5Cmathrm%20dx%3D%5Cint%28-3x%5E2%2B2x%2BC_1%29%5C%2C%5Cmathrm%20dx%5Ciff%20v%28x%29%3D-x%5E3%2Bx%5E2%2BC_1x%2BC_2)
Given that
![v(0)=0](https://tex.z-dn.net/?f=v%280%29%3D0)
, you have
![0=-0^3+0^2+0C_1+C_2\implies C_2=0](https://tex.z-dn.net/?f=0%3D-0%5E3%2B0%5E2%2B0C_1%2BC_2%5Cimplies%20C_2%3D0)
and given
![v(1)=-1](https://tex.z-dn.net/?f=v%281%29%3D-1)
,
![-1=-1^3+1^2+C_1\implies C_1=-1](https://tex.z-dn.net/?f=-1%3D-1%5E3%2B1%5E2%2BC_1%5Cimplies%20C_1%3D-1)
Answer:
Step-by-step explanation:
x + y = 22
22 cards = 26
5(4) +y(2) = 26
20+2y = 26
20-20 +2y = 26-20
2y =6
2y/2 = 6/2
y = 3
andy bought 3 cards
