Find a unit vector normal to the surface zex2−y2=3 at (1,1,3). also find the standard form of the equation of the tangent plane at the given point. note that there are two expressions for the unit normal that differ by a minus sign. to fix a unique answer we give the coefficient of the k component. similarly, the equation of the tangent plane ax+by+cz+d=0 is only unique up to a constant multiple. in order to clarify your answer we give the coefficient of the z so that there is a unique solution. unit normal: n= i+ j+173−−√k tangent plane: x+ y+ z −3=0

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
