Maytag Company earns $2.60 per share. Today the stock is trading at $46. The company pays an annual dividend of $1.60 a. Calculate the price-earnings ratio (Round your answer to the nearest whole number.) Price-earings natio b. Calculate the stock yield. (Round your answer to the nearest tenth percent.) Stock yield
a. The price-earnings ratio of Maytag Company's stock is 17.
b. The stock yield of Maytag Company's stock is 3.48%.
What are the price-earnings ratio and stock yield?The price-earnings ratio is a financial measurement of the worth of Maytag Company.
The price-earnings (P/E) ratio is computed as the current stock price divided by the company's earnings per share.
The P/E ratio shows the potential investor how much to pay per share for each $1 of earnings.
The stock yield is a financial measurement that shows the dividends paid relative to the market value per share.
Data and Calculations:Earnings per share = $2.60
Current share price = $46
Annual dividend = $1.60
a. Price-earnings ratio = Price per share/earnings per share
= 17 ($46/$2.60).
b. Stock yield = Annual dividend per share/Current stock price x 100
= 3.48% ($1.60/$46 x 100)
Thus, while the price-earnings ratio is 17, the stock yield is 3.48%.

Answer:
C
Step-by-step explanation:
The red dotted line we see is the asymptote, which is a line that the functions will never cross.
The asymptotes we see currently is:
x = -3
and
x = 2
We can find the vertical asymptotes using the denominator of the function since the x value that makes the denominator 0 is the asymptote. Since -3 and 2 is the asymptote, the denominator of the function will be:
(x-2) (x+3)
If we look at the answer choices, we can see that C is the only option with a denominator of (x-2)(x+3), so that is our answer.
Answer:
C
Step-by-step explanation:
there are 2 vertical asymptotes at x = - 3 and x = 2
then the factors on the denominator will be (x + 3) and (x - 2)
then
f(x) = [tex]\frac{1}{(x-2)(x+3)}[/tex]

Mary walks from corner D to corner E to corner F on a city block that measures 264 feet wide and 900 feet long. Kate walks diagonally across the city block from corner D to corner F. How much less distance did Kate walk than Mary to get to corner F? Round your answer to the nearest whole foot. Enter only the number.
Step-by-step explanation:
we have a rectangle, that is then cut in half diagonally into 2 right-angled triangles.
in our problem it does not matter which side is the larger and which is the shorter one, because the distance calculation for both cases involve one short and one long side. the sequence does not matter.
Mary walks one short and one large side to get to the opposite corner (from D to F) :
264 + 900 = 1,164 ft
Kate walks diagonally. and that diagonal is the Hypotenuse of the right-angled triangle with a short and a long side of the rectangle.
so, Pythagoras applies :
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90° angle), and a and b are the legs.
in our case that means
diagonal² = 264² + 900² = 69,696 + 810,000 =
= 879,696
diagonal = sqrt(879,696) = 937.9211054... ft ≈ 938 ft
so, Kate walked
1,164 - 938 = 226 ft
less than Mary.

1) Based on the information, the following taxation calculations can be made:
a) Gross Pay per pay period: $500
b) Taxable Income per pay period: $425
c) Since you pay 11% in federal taxes, the Federal tax withholding per pay period is $46.75.
2) The State tax withholding per pay period is $20.
3) The calculation of FICA, Medicare, and the Net Pay per pay period is as follows:
FICA withholding per pay period: $25.50
Medicare withholding per pay period: $6.16
Net Pay per pay period = $326.59
Data and Calculations:Total hours worked per pay period = 40 hours
Rate per hour = $12.50
Pay periods per month = 2
Gross pay per pay period = $500 (40 x $12.50)
Deductions per pay period:Health care = $25
401K deduction = $50
Total deductions per pay period = $75
Taxable income per pay period = $425 ($500 - $75)
Federal taxes = 11%
Federal tax withholding per pay period: $46.75 ($425 x 11%)
Annual taxable income = $10,200 ($425 x 24)
State withholding tax (annual) = $480 {$120 + ($10,200 - $5,000) x 5%}
State withholding tax per pay period = $20 ($480/24)
FICA withholding per pay period: $25.50 ($425 x 6.2%)
Medicare withholding per pay period: $6.16 ($425 x 1.45%)
Net Pay per pay period:Gross Pay $500
Total deductions $75
Taxable income = $425

[3 x 6 1 -8 5] and -5A = [-15 35 -30 -5 40 y]
The value of x in A is ___ and the value of y in B is ___
The value of x in A is 7 and the value of y in B is -15
Functions and valuesFunctions are represented as a function of variable. Given the following sets of numbers.
A = [3 x 6 1 -8 5] and;
-5A = [-15 35 -30 -5 40 y]
Equate the individual values to have:
-5A= -15
Divide both sides by -5
-5A/-5 = -15/-5
A = 3
Determine the value of y
-5A = y
-5(3) = y
y = -15
Similarly;

Answer:
The value of x in A is -7
The value of y in B is -25
Step-by-step explanation:
Everything in the first matrix can be multiplied by -5 to equal everything in the second matrix, since we are dealing with x and y, only the first and third rows matter.
In the first row, we know that 3 times -5 equals -15 and x times -5 equals 35
therefore, -5x=35, with basic algebra we find that X = -7
In the third row, we know that 8 times -5 is 40 and 5 times -5 equals y.
This takes just basic multiplication to find that Y = -25

A common tangent would have to touch T1 at A and also touch T2 at B

the set of integers less than -20
In mathematical notation, the set of integers less than -20 as follows:
{-21, -22, -23, -24, -25, ...}
The set of integers less than -20 is the set of all whole numbers that are smaller than -20. Integers include both positive and negative whole numbers, as well as zero.
In mathematical notation, we can represent the set of integers less than -20 as follows:
{-21, -22, -23, -24, -25, ...}
The set includes all numbers that are smaller than -20, going indefinitely in the negative direction. Each number in the set is obtained by subtracting 1 from the previous number in the set.
For example:
-21 is the integer immediately smaller than -20, so it is included in the set.
-22 is the next integer, smaller than -20, so it is also included in the set.
And this pattern continues indefinitely, encompassing all the integers less than -20.

(scroll to bottom for answer)The equation you want to be using is A(n)+1=(A(n))r because this is a exponential sequence
r represents the ratio, which you said was 25, so basically you said
A(n)
____ = 25
A(n)-1
rthe sum of the first 2 terms are 16, the first two terms being A1 and A2, they need to follow the equation:
A2
__ = 25
A1
lets give them variables to make this a bit easier-
A1 will be x and A2 will be y
x+y=16(1st equation)
y/x=25, 25x=y(2nd equation)
(if you multiply y/x=25 by x you will get that 25x=y, which is where that other equation came from)
going back to x+y=16
subtract y from both sides
x=16-y
use substitution and solve for the second equation
25(16-y)=y
distribute
400-25y=y
add 25y to both sides to get rid of the -25y on the left side while keeping the equation equal
400=26y
divide both sides by 26 and you get 400/26 which simplifies to 200/13
after all that you need to multiply 200/13 by 25, 3 separate times

Write an equation for a rational function with: Vertical asymptotes at x = 4 and x = 1 x-intercepts at x = -3 and x = 6 y-intercept at 5
The rational equation with the desired asymptotes and intercepts is given by:
[tex]f(x) = \frac{-10(x^2 - 3x - 18)}{9(x^2 - 5x + 4)}[/tex]
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.The vertical asymptotes are related to the roots of the denominator, hence:
[tex]f(x) = \frac{a}{(x - 4)(x - 1)} = \frac{a}{x^2 - 5x + 4}[/tex]
The x-intercepts are related to the numerator of the function, hence:
[tex]f(x) = \frac{a(x + 3)(x - 6)}{x^2 - 5x + 4} = a\frac{x^2 - 3x - 18}{x^2 - 5x + 4}[/tex]
The y-intercept is to find a, hence, when x = 0, y = 5, thus:
-18a/4 = 5
18a = -20
a = -10/9
Hence the function is:
[tex]f(x) = \frac{-10(x^2 - 3x - 18)}{9(x^2 - 5x + 4)}[/tex]
