Answer:

The system has no solution.

Step-by-step explanation:

See image. If you graph an inequality, half of the plane are solutions to each inequality. The two inequalities graphed together will show the solution of the system in the area where there is an overlap of the shading. See image. There is no overlap of the shading, so there is no solution.

2 points) Suppose w=xy+yzw=xy+yz, where x=et, y=2+sin(t)x=et, y=2+sin⁡(t), and z=2+cos(3t)z=2+cos⁡(3t). A ) Use the chain rule t

Olenka [21]

Answer:

$\frac{\partial w}{\partial t} = y(e^t) +(x+z)*(cos(t)) - 3y*sin(3t)$

Step-by-step explanation:

First, note that

$\frac{\partial x}{\partial t} = e^{t} \\\frac{\partial y}{\partial t} = cos(t)\\$

And using the chain rule in one variable

$\frac{\partial z}{\partial t} = -3sin(3t)$

Now remember that the chain rule in several variables sates that

$\frac{\partial w}{\partial t} = \frac{\partial w}{\partial x} * \frac{\partial x}{\partial t} + \frac{\partial w}{\partial y} * \frac{\partial y}{\partial t} + \frac{\partial w}{\partial z} * \frac{\partial z}{\partial t}$

Therefore the chain rule in several variables would look like this.

$\frac{\partial w}{\partial t} = y(e^t) +(x+z)*(cos(t)) - 3y*sin(3t)$

The number of milligrams of a certain medicine a veterinarian gives to a dog varies directly with the weight of the dog. If the

Elina [12.6K]

If you would like to know which equation relates the weight and the dosage, you can find this using the following steps:

30-pound dog ... 1 milligram of the medicine
w pound dog ... d milligram of the medicine

30 * d = 1 * w
30 * d = w

The correct result would be 30 * d = w.

konstantin123 [22]

Answer:

13 1/15 or 196/15.

Step-by-step explanation:

First convert the mixed numbers to improper fractions.

7/3*28/5

The multiply the numerators and the denominators.

7*28=196, 3*5=15: 196/15

Hope this helps! :P
