Suppose you need to know an equation of the tangent plane to a surface S at the point P(2; 1; 3). You don't have the equation for S but you know that the curves r1(t) = h2 + 3t; 1 t2; 3 4t + t2i r2(t) = h1 + t2; 2t3 1; 2t + 1i both lie on S. Find the equation of the tangent plane at P.

to find the unit price of an object, you divide the price by object. you are trying to find out how much an object cost per unit.

for instance, lets say you have 50lb of ice cream(object) that cost 8.00 dollars(price). to find the unit cost, we take the 8.00 and divide it by 50, which will give us .16 cents per pound. we can check this by multiplying .16 by 50 = 8.00

so

object = e2

price = d2

unit price = c2

formula for c2:

=d2 / e2

so in my example about ice cream, we would have the following.

e2 = 50

d2 = 8.00

c2 formula:

=d2 / e2

she will do 520 after 52 weeks

hope this : )

is there any answers choices? l can try to you if there is answer choices to this question,so sorry
