A plant engineer wishes to know which of two types of lightbulbs should be used to light a warehouse. The bulbs that
are currently used cost $46.90 per bulb and last 14,000 hours before burning out. The new bulb (at $57.5 per bulb)
provides the same amount of light and consumes the same amount of energy, but it lasts twice as long. The labor
cost to change a bulb is $15.00. The lights are on 20 hours a day, 365 days a year. (Assume that the firm's marginal
tax rate is 25%.) If the firm's MARR is 12%, what is the maximum price (per bulb) the engineer should be willing to
pay to switch to the new bulb? Round the service life of the old bulb to the nearest whole number.

What is a bulb?The term "electronic bulb" is also used to describe incandescent lamps, globes, and bulbs.A gadget that uses electricity to produce light is a light bulb. By passing current through a small wire known as a filament, light bulbs convert electrical energy into visible light. Tungsten, a substance that emits light when electricity is delivered through it, is typically used to make the filament.
How does a bulb function?The lightbulb is essentially a very thin filament of a difficult-to-melt metal, commonly tungsten, enclosed in a glass bulb filled with inert gases to prevent the filament from oxidising and disintegrating.

Parallel to the x-axis means it is just a horizontal line with the value being the y-coordinate of the point:
y = -2
Answer:
y=-2
and m=0 must be your answer
Step-by-step explanation:
as line is parallel to x axis its slope will be zero as it does not have any definite x coordinate
so
equation of line is y-y'=m(x-x')
so m=0 m is slope
y'=-2 and x'=4
so by substituting the values
y+2=0
so y=-2

If yοu take the rebate, yοur mοnthly payment will be $819.08, if yοu chοοse dealer financing, yοur mοnthly payment will be $833.33, yοu wοuld save $342.00 οver the life οf the lοan by taking the rebate οptiοn.
What is meant by lοan?A lοan is a sum οf mοney that is bοrrοwed and is expected tο be paid back with interest. It is a type οf financial transactiοn between a lender and a bοrrοwer, where the lender prοvides the bοrrοwer with a specific amοunt οf mοney, which the bοrrοwer agrees tο repay with interest οver a set periοd οf time.
If you take the rebate, you will have to take out a loan from a local bank for $18,000 at an APR of 6.5% for 2 years.
To calculate the monthly payment, we can use the loan payment formula:
Monthly payment =\(\rm (P \times r) / (1 - (1+r)^{(-n)})\)
where P is the principal amount, r is the monthly interest rate, and n is the total number of payments.
First, we need to calculate the monthly interest rate by dividing the annual percentage rate by 12:
r = 0.065 / 12 = 0.0054
Next, we need to calculate the total number of payments:
n = 2 x 12 = 24
Substituting these values into the loan payment formula, we get:
Monthly payment = (18,000 x 0.0054) / \((1 - (1+0.0054)^{(-24)})\) = $819.08
Therefore, if you take the rebate, your monthly payment will be $819.08.
If you choose dealer financing with no rebate, you will be financing the full $20,000 at a 0% interest rate for 2 years.
Using the same formula, we can calculate the monthly payment:
Monthly payment = (20,000 x 0) / 24 = $833.33
Therefore, if you choose dealer financing, your monthly payment will be $833.33.
Since the monthly payment for dealer financing is higher than the monthly payment for the rebate option, you should take the rebate and get a loan from a local bank.
To calculate the amount you save over the life of the loan, we can subtract the total amount paid for the rebate option from the total amount paid for the dealer financing option:
Total paid for rebate option = $819.08 x 24 = $19,657.92
Total paid for dealer financing option = $833.33 x 24 = $19,999.92
Amount saved = $19,999.92 - $19,657.92 = $342.00
Therefore, you would save $342.00 over the life of the loan by taking the rebate option.

x = 24, y = 120
if you disagree tell me, I just substituted values.
Step-by-step explanation:
10. (6x - 7)° + (3x - 29)° = 180°
i.e they are co-interior angles:
6x + 3x - 7 - 29 = 180°
9x - 36° = 180°
9x = 216°
x = 24.
(6x - 7)° = (8y + 17)°
i.e they are vertically opposite angles;
but x = 24.
6(24) - 7 = 8y + 17
144 - 7 = 8y + 17
120 = 8y
y = 15
11. (9x + 25)° = (13x - 19)°
i.e they are corresponding angles;
25 + 19 = 13x - 9x
44 = 4x
x = 11
(13x - 19)° + (17y + 5)° = 180°
i.e they are adjacent angles;
but x = 11
13(11) - 19 +5 + 17y = 180
17y = 180 - 129
17y = 51
y = 3

Create a factorable polynomial with a GCF of 6. Rewrite that polynomial in two
other equivalent forms. Explain how each form was created. (10 points)
Polynomial: 6x^3 + 12x^2 - 18x
Form 1: 6(x^3 + 2x^2 - 3x)
Explanation: This form was created by factoring out the GCF of 6 from each term in the polynomial.
Form 2: 6x(x^2 + 2x - 3)
Explanation: This form was created by factoring out the GCF of 6x from each term in the polynomial.
In both forms, the GCF of 6 allows us to factor out common factors and simplify the polynomial expression while preserving its original meaning.
To create a factorable polynomial with a greatest common factor (GCF) of 6, we can start by considering the common factors of the terms. Let's construct a polynomial:
Polynomial: 6x^3 + 12x^2 - 18x
To rewrite this polynomial in two other equivalent forms, we can factor out the GCF from each term and simplify.
Form 1: 6(x^3 + 2x^2 - 3x)
In this form, we factored out the GCF of 6 from each term: 6x^3/6 = x^3, 12x^2/6 = 2x^2, and -18x/6 = -3x.
Form 2: 6x(x^2 + 2x - 3)
In this form, we factored out the GCF of 6x from each term: 6x^3/6x = x^2, 12x^2/6x = 2x, and -18x/6x = -3.
We created each form by identifying the common factors in the polynomial and factoring them out. This process allows us to rewrite the polynomial in equivalent forms that emphasize different aspects.
In Form 1, we factored out the GCF of 6, leaving the remaining polynomial inside the parentheses. This form highlights the fact that the polynomial can be written as the product of the GCF and the remaining terms.
In Form 2, we factored out the GCF of 6x, again leaving the remaining polynomial inside the parentheses. This form emphasizes the fact that the polynomial can be written as the product of the GCF and another factor, in this case, x.
By rewriting the polynomial in these two forms, we have created equivalent expressions that emphasize the presence of the GCF and demonstrate the polynomial's factorability.
