The output y and input x of a device are related by y = x + 1.4x3 . (a) Find the values of the output for steady-state operation

erma4kov [3.2K]

Answer:

a) $y(1) = 2.4$ , $y(2) = 13.2$ , b) $y(x) = 2.4 + 5.2\cdot (x-1)$ , $y(1) = 2.4$ , $y(2) = 7.6$

Step-by-step explanation:

a) The values of the output for steady-state operation are:

$y(1) = 1 + 1.4\cdot (1)^{3}$

$y(1) = 2.4$

$y(2) = 2 + 1.4\cdot (2)^{3}$

$y(2) = 13.2$

b) The formula for linearization is:

$y(x) = y(1) +\frac{dy}{dx}|_{x = 1} \cdot (x-1)$

The first derivative of the formula evaluated at x = 1 is:

$\frac{dy}{dx}|_{x=1} = 1 + 4.2\cdot (1)^{2}$

$\frac{dy}{dx}|_{x=1} = 5.2$

The linearized model is:

$y(x) = 2.4 + 5.2\cdot (x-1)$

The output at x = 2 is presented below:

$y(2) = 2.4 + 5.2\cdot (2-1)$

$y(2) = 7.6$

Linearized model offers reasonable approximations for small intervals.

A bag of candy includes pieces with different colors as shown in the table.

zvonat [6]

Part A: About 0.21

We will put the wanted outcome (yellow pieces of candy) over the total number of possible outcomes (total pieces of candy).

$\frac{5}{3+6+5+2+8}$

$\frac{5}{24}$

About 0.21

Part B: About 50

First we will do the same as we did with the yellow pieces of candy, wanted outcomes over possible outcomes.

$\frac{6}{3+6+5+2+8}$

$\frac{6}{24}$

0.25

Now, we will multiply the total 200 pieces by 0.25 since 0.25 of them are estimated to be green.

200 * 0.25 = 50

I estimate about 50 of the pieces to be green.
