Answer:

n⁵ - 2

n²

Step-by-step explanation:

n³−2/n²

To add or subtract expressions, expand them to make their denominators the same. Multiply n³ times n²/n²

n³n² − 2

n² n²

Since n³n²/n² and 2/n² have the same denominator, subtract them by subtracting their numerators.

n³n² - 2

n²

Do the multiplications in n³n² - 2

n⁵ - 2

n²

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.

3 tons 600 pounds = ? Pounds

vovangra [49]

1 ton= 2,000 pounds

STEP 1:
Multiply number of tons by 2,000 pounds

= 3 tons * 2,000 lbs/ton
= 6,000 lbs

STEP 2:
Add the extra pounds given (600 pounds) to calculated pounds in step 1

= 6,000 lbs + 600 lbs
= 6,600 pounds

ANSWER: 3 tons 600 pounds is equal to 6,600 pounds.

Hope this helps! :)

Which function represents g(x) a reflection of f(c)=1/2(3)x across the y-axis

sukhopar [10]

Hello,

I suppose you mean f(x)=3^x /2

g(x)=3^(-x) /2
