Where does the helix r(t) = cos(πt), sin(πt), t intersect the paraboloid z = x2 + y2? (x, y, z) = what is the angle of intersection between the helix and the paraboloid? (this is the angle between the tangent vector to the curve and the tangent plane to the paraboloid. round your answer to one decimal place.)

tube or goog would be a great resource to with that question

ion

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
