Evaluate the line integral, where C is the given curve. z2 dx + x2 dy + y2 dz, C C is the line segment from (1, 0, 0) to (4, 1,
N76 [4]

The line integral is the path of the function along a line having a continuous value.

The integral solved gives the value 111.

The given question is

\int\limits^c {z}^2 \, dx+ {x}^2 \, dy+ {y} ^2\, dz

where C is the line from (1, 0, 0) to (4, 1, 3)

Here

x→ 1⇒ 4

y→  0⇒1

z→  0⇒ 3

Let  t be defined be the range  0≤ t ≤ 1

Then x= 4t+1   :    dx= 4dt

y= t                 ":   dy= dt

z= 3t                : dz= 3dt

Putting the values

\int\limits^1_0{9t^2} \, 4dt + \int\limits^1_0 {16t^2+1+8t} \, 3dt +\int\limits^1_0 {t^2} \,3dt

=  [36(1)²- 36(0)²]+ 3 [16(1)² +1+8(1)] - 3 [16(0)² +1+8(0)]  + [3(1)²- 3(0)² ]

= 36 +75-3+3

= 111

Hello can you please help me posted picture of question
rjkz [21]

Any variable raised to the zero power is 1

y = x^0 is 1

Even any number raised to the power of 0 is 1.

 5555^0 =1

Well not every number. 0^0 is a bit of an exception. 0^0 is undefined and you for that reason you should be careful how you treat it. You should good it when you encounter it. The answer is controlled by circumstances.

That being noted, b^0 in general is 1.

The y intercept is (0,a)

F(x) = 3x + 4<br> g(x) = 4x + 4<br> Find f(x) – g(x)
konstantin123 [22]

Answer:

answer= -x

Step-by-step explanation:

given: f(x)=3x+4

g(x)=4x+4

f(x)-g(x)= 3x+4-(4x+4)

=3x+4- 4x-4

=3x-4x+4-4

= -x+0

= -x
