Answer:
8710 units
Step-by-step explanation:
<em>Step 1: Write all the data</em>
Fixed cost: $9000
Average variable cost: 9.3 per unit
Total cost: 90,000
Total units: x
<em>Step 2: Find the total variable cost</em>
Average variable cost is per unit so it has to be multiplied by the number of units to find the total variable cost.
Total variable cost = average variable cost per unit x number of units
Total variable cost = 9.3x
<em>Step 3: Make the formula for finding x</em>
Total cost = total fixed cost + total variable cost
90,000 = 9000 + 9.3x
81000 = 9.3x
x = 8709.67
Rounded off to 8710 units

45°?
Step-by-step explanation:
The second floor of a building is 20 m above the ground.
From this floor, the angle of
elevation of the top of an eucalyptus tree is 15°
and the angle of depression of the foot of the same tree is 10°
10+15+20=45
Now they are not equal.
You can see that by cross multiplying the fractions, if they equal each other then they are equal and if not then they aren't.\
6/12 ≠ 5/8
48 ≠ 60
Hope this helps :)

Answer:
Step-by-step explanation:
Deducting by the value of the vertex, we can know that the ellipse has a vertical form, since in this case the vertex has the form (0, + -a)
the focus, we know it has the form (0, + -c)
We also know that b ^ 2 + c ^ 2 = a ^ 2
Therefore, we calculate b:
b ^ 2 = a ^ 2 - c ^ 2
replacing:
b ^ 2 = 89 ^ 2 - 55 ^ 2 = 4896
b = 69.97 = 70
Now, we know that the equation of a vertical ellipse is:
replacing we have:
