Pavel [41]

1 plane burns 60x3.9x10^3
= 234x10^3 mls per minute
Required amount =
234x10^3 x 5.1x10^3
= 11934x10^6
= 1.1934x10^10 MLS Answer

I REALLY NEED HELP!!! this is graded and plzzzz no links!!!!!

lara31 [8.8K]

8 x 6 = 48 (regularly you’d divide by two but this is on both sides so we’ll leave it)
4 x 10 = 40 / 2 = 20
6 x 4 = 24 / 2 = 12
8 x 4 = 32 / 2 = 16
48 + 20 + 12 + 16 = 96
hope that helps! message me with any questions on other problems.

Let z = ln(x 2 + y), x = ret . and y = ter . Use the Chain Rule to compute ∂z ∂r and ∂z ∂t at the point where (r, t) = (1, 2).\

Natali [406]

By the chain rule,

$\dfrac{\partial z}{\partial u}=\dfrac{\partial z}{\partial x}\dfrac{\partial x}{\partial u}+\dfrac{\partial z}{\partial y}\dfrac{\partial y}{\partial u}$

where $u\in\{r,t\}$ .

We have component partial derivatives

$\dfrac{\partial z}{\partial x}=\dfrac{2x}{x^2+y}=\dfrac{2re^t}{r^2e^{2t}+te^r}$

$\dfrac{\partial z}{\partial y}=\dfrac1{x^2+y}=\dfrac1{r^2e^{2t}+te^r}$

$\dfrac{\partial x}{\partial r}=e^t$

$\dfrac{\partial x}{\partial t}=re^t$

$\dfrac{\partial y}{\partial r}=te^r$

$\dfrac{\partial y}{\partial t}=e^r$

Putting the appropriate pieces together and setting $(r,t)=(1,2)$ , we get

$\dfrac{\partial z}{\partial r}(1,2)=\dfrac{2e^3+2}{e^3+2}$

$\dfrac{\partial z}{\partial t}(1,2)=\dfrac{2e^3+1}{e^3+2}$
