Evaluate the line integral ∫cf⋅dr, where f(x, y,z)=2sinxi+cosyj+3xzk and c is given by the vector function r(t)=t4i−t3j+t2k , 0≤t≤1.

95.03 is the answer. hope this !

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

the correct option is b
