Answer: x = 16
Step-by-step explanation:
If RQ is the bisector, that means the angle is cut in half. Therefore angles PRQ and QRS are equal to each other.
4x+6 = 7x-42
subtract 7x from both sides
-3x+6 = -42
subtract 6 from both sides
-3x = -48
divide both sides by -3
x = 16
(1/x) - (2x/(1+x^2)) = 0
Multiply by x(x^2+1)
1(x^2+1)+(−2x)(x)=0x(x2+1)
−x^2+1=0(Simplify both sides of the equation)
−x^2+1−1=0−1(Subtract 1 from both sides)
−x^2=−1
−x^2−1=−1−1(Divide both sides by -1)
x^2=1
x=ñ1(Take square root)
x=1 or x=−1
Answer:
a. $56,000.
Step-by-step explanation:
The pretax income is the income earned after the expenses incurred have been deducted from the total sales. It is the income on which the taxation rate may be applied to.
The total expense is the sum of the fixed and variable expenses. The total sales is the product of the units selling price and the number of units sold while the total variable cost is the product of the variable cost per unit and the total units.
Hence pretax income,
= $10.80(24,800) - $5.80(24,800) - $68,000
= $56,000
