liq [111]

Answer:

∂u/∂xi = i·cos(sn)

Step-by-step explanation:

For u = sin(v), the partial derivative of u with respect to xi is ...

∂u/∂xi = cos(v)·∂v/xi

In this case, v=sn, and ∂sn/∂xi = i, so the derivatives of interest are ...

∂u/∂xi = i·cos(sn)

The temperature is 2 degrees and drops to -15 degrees overnight. Write and then evaluate a subtraction expression to determine t

KiRa [710]

Answer:

-17 degrees

Step-by-step explanation:

Given that:

Initial temperature = 2 degrees

Final temperature = -15 degrees

To Determine:

The change in temperature.

Solution:

First of all, let us have a look at the method for calculating the change in any quantity.

Let the initial quantity = $a$

Let the final quantity = $b$

Change in quantity = Final quantity - Initial quantity = $b - a$

Here, we are given the quantity as temperature.

where $a = 2$ degrees and

$b = -15$ degrees

Therefore, the change in temperature = -15 - 2 = $\bold{-17}$ <em>degrees</em>
