Line k contains the points (-4,0) and (3,2). line m contains the points (-3,2) and (4,0). if line k is written in the form y=m1x
Misha Larkins [42]

Answer:

0

Step-by-step explanation:

(-4,0) and (3,2)

m1=(2-0)/(3+4)=2/7

y=2/7x+b1, using point (-4,0) to find b1 (substitute x=-4 and y=0 in the form)

0=2/7*(-4)+b1 ⇒ b1= 8/7

-----

(-3,2) and (4,0)

m2=(0-2)/(4+3)= -2/7

y= -2/7x+b2, using point (4,0) to find b2 (substitute x=4 and y=0 in the form)

0= -2/7*4+b2 ⇒ b2=8/7

----

m1b2+m2b1= 2/7*8/7 -2/7*8/7=0

The partial pressure of carbon dioxide in a mixture is 0.31 atm.
juin [17]

Answer:

P_{Co2}= X_{Co2} P_{tot}

Where P_{tot} represent the total pressure and X_{Co2} the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:

P_{tot}= \frac{P_{Co2}}{X_{Co2}}

And replacing we got:

P_{tot}= \frac{0.31 atm}{0.46}= 0.674 atm

Step-by-step explanation:

For this case the partial presure of carbon dioxide is given by:

P_{Co2}= X_{Co2} P_{tot}

Where P_{tot} represent the total pressure and x_{Co2} the fraction of carbon dioxide is 0.46 and we can find the total pressure with this formula:

P_{tot}= \frac{P_{Co2}}{X_{Co2}}

And replacing we got:

P_{tot}= \frac{0.31 atm}{0.46}= 0.674 atm
