Let f(x, y,z)=x+yz and let C be the line segment from P=(0,0,0) to (6,3,1). (a) Calculate f(c(t)) and ds=∥c′(t)∥dt for the parametrization c(t)=(6t,3t,1t) for 0≤t≤1. (b) Evaluate ∫Cf(x, y,z)ds.

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
