Kawamura, a careful utility maximizer, consumes peanut butter and ice cream. Assume that both peanut butter and ice cream are normal goods and that diminishing marginal utility applies to both goods. Right after he achieves the utility-maximizing level of consumption of the two goods, the price of peanut butter falls. After he adjusts to this event, the marginal utility of peanut butter goes and that of ice cream goes .

The marginal utility of peanut butter goes down and that of ice cream goes up.

Explanation:

The substitution effect states that when the price of a product falls, it will lead to a rise in the quantity demanded of the product as buyers will buy more of the product that is now relatively cheaper.

And as more of a good is bought, its marginal utility falls. And as less of a product is bought, its marginal utility increases.

Based on the above explanation therefore, the marginal utility of peanut butter goes down and that of ice cream goes up after Kawamura adjusts to the event.

This is because as more of peanut butter is bought due to the fall in its price, its marginal utility falls. And as less of ice cream is bought as it is now relatively more expensive, its marginal utility increases.

answer; /// i believe its (bas design);

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.
