Answer: 18th year
In this question, the income is increasing each year with the same amount, first-year income is $20,400 and 11th-year income is $31,400. From this information, you can determine how much the income increases every year. The calculation would be:

Income year Y= first income + {(Y-1) * income increase per year )}
$31,400= $20,400 + 10 * income increase per year
10* income increase per year= $11000
income increase per year= $1100

Using the same formula you can find the answer

Income year Y= first income + {(Y-1) * income increase per year )}
$40,200= $20,400 + Y* 1100
1100Y= 40,200-20,400= 19800
Y= 19800/1100= 18 year.

URGENT!! I have been trying to ask this question for a while but I keep getting fake answers: Find an equation in standard form
Shalnov [3]

Answer:

Step-by-step explanation:

y=a(x-h)^2+k

-12=a(1-h)^2+k

16=a(3-h)^2+k

subtract

a(3-h)^2-a(1-h)^2=28

a[(3-h)^2-(1-h)^2]=28

a=2

2[(3-h)^2-(1-h)^2]=28

(3-h)^2-(1-h)^2=14

9+h^2-6h-(1+h^2-2h)=14

9+h^2-6h-1-h^2+2h=14

-4h+8=14

-4h=6

h=-3/2

16=2(3+3/2)^2+k

16=2×81/4+k

k=16-81/2=-49/2

so y=2(x+3/2)²-49/2
