Air is compressed from 2.8 l, 17 degree c and 95 kpa to 0.41 l inside a piston-cylinder device. the compression is reversible and adiabatic. r_air = 0.287 kj/kg. k. using variable specific heat analysis, determine: a. the temperature after compression, in k. b. the pressure after compression, in kpa. c. the work done on the system, in kj.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

1st, 348.600

2nd, 256.905

3rd, 892.500

4th, 6937

last one stays the same since it has no decimal
