Find the equation of the plane with the given description. contains the lines r1(t) = 2, 1, 0 + t, 2t, 4t and r2(t) = 2, 1, 0 +
Genrish500 [490]
The intersection point of the two lines is (2,1,0).
The respective direction vectors are
L1: <1,2,4>
L2: <4,1,15> 
Since the normal vector of the required plane is perpendicular to both direction vectors, the normal vector of the plane is obtained by the cross product of L1 and L2.
i  j    k
1 2  4
4 1 15
=<30-4, 16-15, 1-8>
=<26, 1, -7>

We know that the plane must pass through (2,1,0), the equation of the plane is

26(x-2)+1(y-1)-7(z-0)=0
simplifying,
26x+y-7z=52+1+0=53
or
26x+y-7z=53

Check:
Put points on L1 in the plane
26(t+2)+(2t+1)-7(4t+0)=53   ok
For L2,
26(4t+2)+(t+1)-7(15t+0)=53  ok

Answer:

x=2 y=8 ---> (2;8)

Step-by-step explanation:

2x+5y=44

6x-4=y

1.

2x+5(6x-4)=44

2x+30x-20=44

32x=64

x=2

2.

6x-4=y

6*2-4=y

12-4=y

y=8

Determine the temperature of 2.6 moles of gas contained in a 5.00-L vessel at a pressure of 1.2atm.
strojnjashka [21]

Answer:

28.108 K.

Step-by-step explanation:

Given: Pressure (P)= 1.2atm

           Number of moles (n)=  2.6 moles

           Volume (V)= 5.00-L

Now finding the temperature (T).

Formula; T= \frac{P\times V}{n\times R}

R is a constant factor which makes other factors work together.

There is a numerical value for R which we use is 0.0821 \times \frac{L.atm}{mole.K}

∴ Temperature (T)= \frac{1.2\times 5}{2.6\times 0.0821 \frac{L.atm}{mol.K} }

⇒ Temperature (T)= \frac{6}{0.21346} = 28.1083\ K

∴ Temperature is 28.108 K
