Integrate f(x, y,z)=x+sqrt(y)-z^3 over the path from (0,0,0) to(2,4,2) given by Upper C1: r(t)=ti+t^2j, 0 less than or equals t less than or equals 2 Upper C2: r(t)=2i+4j+tk, 0 less than or equals t less than or equals 2.

answer: a

step-by-step explanation:

10.2 units

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
