lukranit [14]

Answer:

Inelastic

Explanation:

The price elasticity of demand is the degree of responsiveness of demand for a product or service to a unit change in price. The demand for a product is said to be elastic when a change in price has a relatively large effect on the demand for the product, unitary when there is a percentage change in price brings about an equal percentage change in the demand for the product, and inelastic when a change in the price of a product brings about a smaller change in the demand for the product.

<em>In the case of the DVD rentals, a 10% increase in price brought about only a 5% drop in demand. Hence, the demand for DVD rentals is said to be inelastic because a change in the price brought about a smaller change in the demand for DVD rentals.</em>

Andrews [41]

Answer:

The answer is "1.278498"

Explanation:

Given formula:

f = (\frac{1}{2L}) \sqrt{(\frac{T}{m})}

f ( \ at\  L = 20.0) \  = 2380\\\\for \ L + x ,\\\\  f = 2237\  H_zso,

\to \frac{2380}{2237} = \frac{(L + x)}{L}\\\\\to \frac{2380}{2237} =  1 + (\frac{x}{L})\\\\\to 1.0639249=1+(\frac{x}{L})\\\\\to 1.0639249 -1=(\frac{x}{L})\\\\\to \frac{x}{L}= 0.0639249\\\\ \to x= 0.0639249\times 20.0 \\\\ \to x= 1.278498
