<span>Domain: {–4, 0, 8}; Range: {2, 1, 5, 10}
In the domain, there can only be values for which is possible for.
Like There is no 5 for the domain, because there is no x like that.
Hope this helps :)</span>
Propane costs $3.50 per hundred pounds,
and there is a $6 monthly delivery fee.
A family has budgeted $85 for their propane this month.
Let 'x' hundreds of pounds can the family use without going over budget
Here family has budgeted $85 for their propane.
So the cost for Propane = $ 3.5x
One month delivery fee $6
Therefore cost + delivery charge not exceed $85
So 3.5x + 6 ≤ 85
3.5x=85-6 =79
x = 22.57
Therefore 22 hundreds of pounds can the family use without going over budget
Step-by-step explanation:
Sum of arithmetic terms = n/2 × [2a + (n - 1)×d], where 'a' is the first term, 'd' is the common difference between two numbers, and 'n' is the number of terms.
this is the same as n/2 × (a1 + an), because
an = a1 + (n-1)×d
so, for the series above :
a or a1 = 2
d = 7, as every new term is the previous term plus 7.
for n
37 = a1 + (n-1)×d = 2 + (n-1)×7
and now solve for n
35 = 7n - 7
42 = 7n
n = 6
so, the sum of all terms is
6/2 × (2+37) = 3×39 = 117

My answers:
a, If workers are free to move between sectors, the wages in each sector will be equal. If wages are not equal, the workers will be motivated to move to sectors with higher wages and this will make a higher salary reduction, and lower wages will increase until they equal.
b. Since there are 100 workers in total,we have:
Ls =100- Lm = 100 -4w
Lm = 4w
Now set this equal to the labor demand for manufacturing equation and solve for w:
4w = 200 - 6w
w = $20.
Substitute w =20 into the two labor demand equations, we have LM = 80 and LS i= 20
c. If the wage in manufacturing is equal to $25 then
Lm=200-6(25) = 50
d. There are now Ls = 50 workers employed in the service sector and the wage:
Ls=100-4Ws
<=> 50 = 100 -4Ws
<=> Ws = 12.5
e. Wages in the manufacturing sector will remain at 25 dollars and jobs will remain at 50. If wages are reserved for the service sector is 15 dollars, then jobs in the service sector will be 40. Therefore 10 unemployed and the unemployment rate is 10%.
