1) Given dy / dx = x^2 + 4 = y is the function whose derivative is x^2 + 4.
2) y = x^3 / 3 + 4x + constant
Prove d y / dx = 3x^2 / 3 + 4 + 0 = x^2 + 4
Answer: x^3 / 3 + 4x + C
If you choose a blue marble first its the probability of 3/12 simplified to 1/3 and then the probability of choosing a red next is 5/11 as you didnt replace the one blue marble
You can say 1 and 7/11 is 18/11 and 2 and 1/2 is 5/2 so :
18/11 ÷ 5/2 so 18/11 * 2/5 = 36/55 = 0.654 :)))
i hope this is helpful
have a nice day
