Answer:

c = ± \sqrt{\frac{e}{m} }

Step-by-step explanation:

Given

e = mc² ( divide both sides by m to isolate c² )

\frac{e}{m} = c² ( take the square root of both sides )

c = ± \sqrt{\frac{e}{m} }

Suppose a household’s income increases from $2500 to $3000 and quantity demanded changes from 190 to 150. What is the income ela
shusha [124]

The income elasticity for the household is -1.05.

<h3>What is the income elasticity?</h3>

Income elasticity measures how quantity demanded changes when there is a change in the income of a person / household

Income elasticity = percentage change in quantity demanded / percentage change in income

  • percentage change in income = (3000 / 2500) - 1 = 0.2 = 20%
  • percentage change in quantity demanded =( 150 /190) - 1 = -0.21 = -21%

Income elasticity = -21% / 20 = -1.05

\large \underline{ \mathbb{QUESTION:}}

The lifeguard of the beach resort is on his post which is 4 m high. A boy in the pool is 9 meters away from him. Find the angle of depression from the lifeguard to the boy.

\large\underline{ \mathbb{ANSWER  \: \& \: SOLUTION:}}

\large \tt{ tan \: x \:  =  \:  \frac{opposite}{adjacent} }

\large \tt{tan  \: x \:  =  \:  \frac{4}{9}}

\large \tt{ \:   \: \:  \:   \:  \:  \: \: x \:  =  \:  tan ^{ - 1}  \:  (0.444)}

\large \tt {\:  \:  \:  \:  \:  \:  \:  \: x \:  =  \: 23.96 ^{o} }

\:\:\:\:\:\:\:\: \large \boxed{\tt{\red{  x \:  =  \: 24 ^{o} }}}

Therefore the angle of depression from the lifeguard to the boy is 24°.
