Use the graph below to answer the following question.

zlopas [31]

Answer:

$Ce_2(SeC_4)_2$ is least soluble at high temperatures.

Step-by-step explanation:

The compound that has least solubility when the temperature increases is the one that has the least value along y-axis (solubility) for greater values along x- axis (temperature).

From the graph we see that $KNO_3$ is most soluble at high temperatures (in fact its solubility increases with increase in temperature), and $Ce_2(SeC_4)_2$ is least soluble for high temperatures (its solubility decreases with increase in temperature) .

Thus, $Ce_2(SeC_4)_2$ is least soluble at high temperatures.

The family of functions y = ce^{-2x} + e^{-x} is solution of the equation y' + 2y = e^{-x}. Find the constant c which defines th

Rufina [12.5K]

Answer:

$c = 1190.2$

Step-by-step explanation:

We have the following solution:

$y(x) = ce^{-2x} + e^{-x}$

We want to find the value of x that satisfies the following condition:

y(3) = 3.

This means that when x = 3, y = 3. So

$y(x) = ce^{-2x} + e^{-x}$

$y(3) = ce^{-2*3} + e^{-3}$

$3 = ce^{-6} + e^{-3}$

$3 = ce^{-6} + 0.0498$

$ce^{-6} = 2.9502$

$c = \frac{2.9502}{e^{-6}}$

$c = 1190.2$

So, you are going to start with the first # and move left however many digits the second number is; if they are both negative and you are adding, just act like you are adding two regular #s together, just put a negative sign in front
