Find the value of integral ∫ C ( x + y + z ) d z , where C is parametrized by → r ( t ) = ⟨ 17 sin ( 5 t ) , 15 cos ( 5 t ) , 8 cos ( 5 t ) ⟩ for 0 ≤ t ≤ π .

they go with it happens or they mite give a chance?

step-by-step explanation:

b

c(x)= 6x + 3

step-by-step explanation:

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
