The estimated monthly sales of Mona Lisa paint-by-number sets is given by the formula q = 104e−3p2 + p, where q is the demand in monthly sales and p is the retail price in hundreds of yen. Determine the price elasticity of demand E when the retail price is set at ¥200.

The price elasticity of demand is 0

Step-by-step explanation:

The demand function for monthly sales is given as:

q = 104e^-3p^2 + p

The price elasticity of demand E is obtained by differentiating q with respect to p

E = dq/dp = (-6p + 1) × 104e^-3p^2 +p =

When p = ¥200

E = (-6×200 + 1) × 104e^-3(200)^2 + 200 = -1199 × 104(0) = -1199 × 0 = 0

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
