Answer:
$835.20
Step-by-step explanation:
First you need to find out how many profit you had at first by multiplying 145 and $44.17.
So, 145*$44.17 = 6404.65
Then find out how much profit you had after it decreased by multiplying 145 and $38.41.
So, 145*$38.41 = 5569.45
Now to find how much profit you lost, you have to subtract $6,404.65 and $5,569.45.
$6,404.65 - $5,569.45 = $835.20
Answer:
Answer: x = 33, y = 81..........
Of the four x-coordinates to choose only 1/√(11) belongs can belong to the unit circle.
The other three x-coordinates are greater than 1, then they are out of the unit circle.
The unit circle formula is x^2 +y^2 = 1
Then to find the y-coordinate given the x-coordinate you can solve for y from that formula:
y^2 = 1 - x^2
y = (+/-)√(1-x^2)
Substitute the value of x
y = (+/-)√{1 - [1/√(11)]^2} = (+/-) √{(1 - 1/11} =(+/-) √ {(11 -1)/11 =(+/-)√(10/11) ≈ +/- 0.95
The common difference, d, can be determined by subtracting the two consecutive values:
1 - 5 = -4
-3 - 1 = -4
-7 - -3 = -4
Then, using the equation:
an = a1+ d(n-1)
a_21 = 5 + (-4)(21 - 1)
a_21 = -75
The answer is letter D. I hope I was able to help you. Have a good day!
