Answer:
D. sometimes less than zero and sometimes greater than zero.
Step-by-step explanation:
The income elasticity of demand is the responsiveness of the increase in the consumers income versus the quantity of goods and services demanded in an economy. we have five types of income elasticity of demand which are namely high elasticity, unitary elasticity, low elasticity and negative elasticity.
in high elasticity of demand when income rises then we see a much bigger increase in the quantity of goods and services demanded therefore positive coefficient.
The unitary elasticity of demand is when the income increases at the same rate the quantity of goods and services demanded rises therefore a coefficient is constant.
the low elasticity of demand is when income increases at a lower rate than the increase in the quantity demanded. positive but low coefficient.
The negative elasticity of demand is when an income increases and the quantity decreases therefore a negative coefficient is seen.
Answer:
Step-by-step explanation:
Perimeter = 84 feet
Side One = Side Two + 12 feet
Side Two + 17 = Side Three
Side Two + Side Two = Side Four
Perimeter = (Side Two + 12) + (Side Two) + (Side Two + 17) + (Side Two + Side Two) = 5 x (Side Two) + 29 = 84
5x + 29 = 84
5x = 55
x = 11
Side Two = 11 feet
Side One = 11 + 12 = 23 feet
Side Three = 11 + 17 = 28 feet
Side Four = 11 X 2 = 22 feet
Answer:
1.75=b
Step-by-step explanation:
do the equation:
-2=3/4(5)+b
-2=-3.75+b
+3.75 to both sides
1.75=b
Semicircle perimiter=1/2circumferece+diameteter
diameter=2r
c=2pir
so 1/2circumference=1/2(2pir)=pir
d/2=r
given
d=30
d/2=30/2=15=r
perimiter=pir+d
perimiter=15pi+30
aprox
perimiter=77.1239
total cost=cost per foot times feet
total cost=9.25 times 77.1239
total cost=713.396
it will cost $713.40
