Answer:
Option B.
{–9 + i√225 / 24, –9 – i√225 / 24}
Step-by-step explanation:
12a² + 9a + 7 = 0
Using formula method, the solutions to the equation can be obtained as follow:
Coefficient of a² (a) = 12
Coefficient of a (b) = 9
Constant (c) = 7
a = –b ±√(b² – 4ac) / 2a
a = –9 ±√(9² – 4 × 12 × 7) / 2 × 12
a = –9 ±√(81 – 336) / 24
a = –9 ±√(– 225) / 24
Recall
–225 = –1 × 225
Thus,
–9 ±√(– 225) / 24 = –9 ±√(–1 × 225)/24
Recall
√(–1 × 225) = √–1 × √225 = i√225
Thus,
–9 ±√(–1 × 225)/24 = –9 ± i√225/24
Therefore,
a = –9 ± i√225/24
a = –9 + i√225 / 24 or –9 – i√225 / 24
Therefore, the solutions to the equation are:
{–9 + i√225 / 24, –9 – i√225 / 24}
The area of two yards is 18ft
Pretty sure it’s 2, based on what I’m seeing
Answer:
A. $16,079
Step-by-step explanation:
You are given the income of a married couple and the tax table applicable to married couples. To find the amount of tax owed, you first find the applicable line in the table, then do the computation it tells you.
The applicable line for an income of $110,000 is the one that says ...
"77,401 to 165,000"
The left (Tax Rate) column of that line has "22%", and the right (Tax Owed) column tells you the computation you need to make.
You find "the excess over $77,400" by subtracting that amount from the $110,000 income:
the excess over $77,400 = $110,000 -77,400 = $32,600
__
Then the tax owed is 22% of this amount plus $8907:
tax owed = $8,907 + 0.22 × 32,600
= $8,907 + 7,172
tax owed = $16,079
I dont really know the difference between them lol; also it's a little blurry
sorry
