Considering the given figure we have that
< BAC = < CAD definition of angle bisection
< BAC = < BCA base angles of isosceles triangle
What is angle bisection?This refers to when angles are being shared or divided into two equal parts.
In the given problem, line AC is the bisector of < BAC. creating wo equal angles in the process. hence
< BAC = < CAD definition of angle bisection
Triangle BAC is an isosceles triangle, since the sides BA and BC are equal. the angles are also equal therefore
< BAC = < BCA base angles of isosceles triangle
Line AC is also a transversal line, connecting the two parallel lines BC and AD. This creates opportunity for alternate angle theorem

If y varies directly as x, find the constant of variation k and the direct variation equation for the situation.

Variation refers to differences in characteristics between individuals of the same species or between different genera or species. The formula is y = 0.25x.
What is meant by variation equation?A variation is a relationship between one set of values for one variable and another set of values for another variable. Variation in direct. If m is a nonzero constant and b = 0, then the function y = mx (often written y = kx) is a direct variation of the equation y = mx + b. If y varies directly as x and y = 6 when x = 2, the constant of variation is k = 3. As a result, the equation for this direct variation is y = 3x.The direct variation equation is a two-variable linear equation given by y = kx, where k is the constant proportionality. In a coordinate plane, the direct variation graph is a straight line.Therefore,

What do you mean by direct variation?If two quantities change by the same amount, they are said to follow a direct variation. As a result, when one quantity changes, the other follows suit, increasing when the first changes and decreasing when the first changes. To put it another way, two quantities are said to be directly proportional to one another if the ratio of the first to the second is a constant term. The coefficient or constant of proportionality is the name given to this constant quantity.The mathematical relationship between the two quantities in the direct variation formula makes it so that one of the variables is a constant multiple of the other. The sign "∝" is used to indicate that two quantities are directly proportional to one another or directly varying from one another. Assuming that x and y are two quantities that are directly varying, they are stated as follows: y∝ xThe direct variation formula is expressed as follows when the proportionality sign is omitted.Calculation
Given, y =2 and x=10
we know the direct relation in y∝ x
so, y = kx, where k is the proportionality constant

Answers
The operating income of Division B will increase by $640,000
How to calculate the increase in Division B's operating income?
Given that: Division B incurs variable costs of $10 per unit and a transfer price of $18 per unit is established between the two divisions and 80,000 units of materials are transferred to Division A
This cost of production by division B is:
cost = $10 × 80,000 = $800,000
Division B uses a transfer price of $18 per unit. That is:
Selling price = $18 × 80,000 = $1,440,000
Operating income increase = Selling price - cost
Operating income increase = $1,440,000 - $800,000 = $640,000
Therefore, Division B's operating income increase will be $640,000

Given the function is f(n) = 2.2 [ f(n-1) ] Here, f(1) = 10 then we have to create the first five terms of the sequence defined by the function.
Since f(1) = 10
f(2) = 2.2 [ f (2-1) ] = 2.2× [ f (1) ]
= 2.2 × 10 = 22
f (3) = 2.2 [ f (3-1)] = 2.2 × [ f (2) ]

f(4) = 2.2 [ f(4-1) ] = 2.2× [ f(3)]

f(5) = 2.2 [ f(5-1) ] = 2.2× [ f(4)]

Answers
On October 28, Lee received proceeds of $71,153.66 from the discounted note.
What is note discounting?Discounting a note involves receiving immediate cash by selling it to a financial institution at a discount.
The implication of discounting a note is that the receiver gets less than the maturity value.
The maturity value is the face value of the note plus the computed interest.
Face value of the note receivable = $70,000
Interest rate = 6.34%
Note period = 120 days
July 26 - October 28 = 94 days
Maturity value of the note receivable = The Face Value + Interest
= $71,459.07 [$70,000 + ($70,000 x 6.34% x 120/365)]
Bank discount rate = 6%
The discount period from October 28 to Nov 22 = 26 days (120 - 94)
Bank discount = Maturity Value x Discount Rate x Discount Period
= $305.41 ($71,459.07 x 6% x 26/365)
Proceeds = Maturity value - Bank discount
= $71,153.66 ($71,459.07 - $305.41)
Thus, by discounting the note receivable at LB Bank at 6%, Lee received $71,153.66 instead of the $71,459.07 it would have received at maturity.

How does FIFO differ from LIFO?FIFO, which means First-in, First-out, computes the cost of goods sold based on the assumption that the physical flow of goods sold depends on the earlier inventory in stock.
FIFO can be applied under both the perpetual and periodic inventory systems, unlike LIFO.
LIFO means Last-in, First-out, and as a cost flow assumption assigns the cost of goods sold based on the latest inventory purchases.
LIFO cannot be used under the perpetual inventory system.
