Jamal takes a rectangular piece of fabric and cuts from one corner to the opposite corner. If the piece of fabric is 8.8 inches
LuckyWell [14K]

Answer:

17.16

Step-by-step explanation:

So if the area of the rectangle is 8.8*3.9=34.32, L*W=H, then the triangle which has the same length and width, would have L*W*1/2. If you fill in the variables, then you would get 8.8*3.9*1/2=17.16. You can do this on any calculator, and please put my answer as the brainliest.✌

Can someone pls help me find the second derivative of this. I need to find the concave up and down intervals but I’m having trou
KonstantinChe [14]

Starting from

f(x)=\dfrac14(x+1)^{\frac83}-4(x+1)^{\frac23}

take the first derivative using the power and chain rules:

f'(x)=\dfrac83\cdot\dfrac14(x+1)^{\frac83-1}-\dfrac23\cdot4(x+1)^{\frac23-1}

f'(x)=\dfrac23(x+1)^{\frac53}-\dfrac83(x+1)^{-\frac13}

Now take the second derivative:

f''(x)=\dfrac53\cdot\dfrac23(x+1)^{\frac53-1}-\left(-\dfrac13\right)\cdot\dfrac83(x+1)^{-\frac13-1}

f''(x)=\boxed{\dfrac{10}9(x+1)^{\frac23}+\dfrac89(x+1)^{-\frac43}}

Optionally, you can condense the second derivative a bit by factoring out \frac89(x+1)^{-\frac43}, which gives

f''(x)=\dfrac89 (x+1)^{-\frac43} \left(80(x+1)^{\frac63}+1\right)

f''(x)=\dfrac89 (x+1)^{-\frac43} \left(80(x+1)^2+1\right)

f''(x)=\dfrac89 (x+1)^{-\frac43} \left(80x^2+160x+81\right)
