Plug in 2 and 4 for every instance of x in the function g(x).
g(x) = 0.023x³ + 0.4x² − 2.1x + 8.3
g(2) = 0.023(2)³ + 0.4(2)² − 2.1(2) + 8.3 = 5.884
g(4) = 0.023(4)³ + 0.4(4)² − 2.1(4) + 8.3 = 7.772
answer: 5.884 and 7.772
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

Answer:
The formula of the volume of a cylinder is known as follow
<h2>V= πr²h</h2>
Where
π is 3,14 or 22/7.
d (diameter) is a straight line segment that crosses a center and connects two points on the circle.
r is the radius of the to part of the cylinder.
h is the height.
we can subsitute to our formula knowing that
d = 4cm (turn to r = <em>2cm</em>,because the formula use r) ; h = 11cm
V = πr²h
= 3,14 × 2² × 11
= 3,14 × 4 × 11
= 3,14 × 44
= 138,16 rounded off (138,2cm3) result
Answer:
42
Step-by-step explanation:
there are a possible 6 combinations for a sum of 7:
1,6
6,1
2,5
5,2
3,4
4,3
so we can create this proportion:
7/36 = n/216
n = # times to roll a sum of 7 out of 216
now cross-multiply:
36n = 1512
n = 1512/36
n = 42
Answer:
a = 180 - b - c
Step-by-step explanation:
given 180 = a + b + c or
a + b + c = 180 ( isolate a by subtracting b from both sides then c )
subtract b from both sides
a + c = 180 - b
subtract c from both sides
a = 180 - b - c
