Answer:

Step-by-step explanation:
<em>Since equations are not listed, i will simply figure out the correct answer.</em>

Profit is Income MINUS Cost.
The cost is a fixed cost of 2,100 per month.
Also a variable cost of 70 per unit (x), if x units sold, then variable cost would be "70x"
Total Cost = 2100 + 70x
Now, the income is from sales of each unit. Each unit sells for $84 and if x units sold, company's income would be:
84x
So, profit will be:
Profit = Income - Cost
Profit = 84x - (2100 + 70x)
Profit = 84x - 2100 - 70x
Profit = 14x - 2100
We can write the equation as:

I believe it’s C, because in a recursive rule you must have (n-1), this shows that you’re using the previous term to solve for the next one.
Answer:
Previous balance = $199.19
Annual rate =14%
finance charge=14%of $198.19=$27.7466
New balance =$199.19+$27.7466-$97.50-$75.75=$53.6866
Por determinante:
5...1...1
1...0...1 = 0 --> se o determinante for igual a 0, os pontos estarão alinhados.
3...3...1
calculando: (5 x 0 x 1 + 1 x 1 x 3 + 1 x 3 x 1) - (1 x 0 x 3 + 1 x 1 x 1 + 3 x 1 x 5) =
0 + 3 + 3 - 0 - 1 - 15 =
6 - 1 - 15 =
5 - 15 = - 10 --> como não deu zero, os pontos não estão alinhados.
Answer:
A)94.5 cm
Step-by-step explanation:
height = 9cm
Base 1 = 5cm
Area of a Trapezoid = 1/2 × (b1 + b2)h
h = 9cm
b1 = 5cm
b2 = (9 cm + 5cm + 2cm) = 16cm.
Area of Trapezoid
= 1/2 (5 + 16) × 9
= 1/2 × 21 × 9
= 94.5 cm
Option A is the correct answer
