1.) The answer is Letter B - 2,803.86 (Add the balance, the interest, and the late fee)
   Credit balance      : 2,745.69
   Monthly interest   :       29.17 [(2,745.69 x 12.75%) / 12 months]
   Late fee payment : <u>     29.00
</u>                                   2,803.86
<u>
</u>2.) The answer is Letter D - 52.12 (get the difference between the first store and the second store after deducting the 10% discount)
<u />   First store      : 268.97
   Second store :<u> 216.86</u> [240.95 - (240.95 x 10%)]
 <u />                             52.12

1. X^4(dy/dx) +x^3y =- sec (xy)<br><br>Integral by separation of variables? <br>​
atroni [7]

Answer:

<h2 />

Step-by-step explanation:

given the differential equation x^4(dy/dx) +x^3y =- sec (xy). Solving using the variable separable method;

x^{4} \frac{dy}{dx} +x^{3}y = -sec(xy)\\x^{3}(x\frac{dy}{dx} + y) =  -sec(xy)\\let \ v=xy\\\frac{dv}{dx} =  x\frac{dy}{dx} + y(implicit \ in\ nature)\\

Substituting v and dv/dx into the equation above we have;

x^{3}\frac{dv}{dx} = -secv

Separating the variables:

-\frac{dv}{secv} = \frac{dx}{x^{3} }

-cosvdv = x^{-3}dx\\ integrating\ both\ sides\\-\int\limits {cosv} \, dv = \int\limits {x^{-3} } \, dx\\-sinv = \frac{x^{-2} }{-2} + C\\since\ v = xy\\-sinxy = \frac{x^{-2} }{-2} + C\\2sin(xy) = x^{-2} -2C\\2 sin(xy) = \frac{1}{x^{2} } -K (where\ K = 2C)\\

The final expression gives the solution to the differential equation.

When 4 is added to three times of a number, the answer is the same as subtracting 2 from the number. What is the number ?
Orlov [11]

Answer:

- 3

Step-by-step explanation:

let n be the number , then

3n + 4 = n - 2 ( subtract n from both sides )

2n + 4 = - 2 ( subtract 4 from both sides )

2n = - 6 ( divide both sides by 2 )

n = - 3

The number is - 3

As people exited a movie theater, they were informally surveyed about whether they enjoyed the movie or not.
guajiro [1.7K]
I'll just do a relative frequency for the whole table:

                   Enjoyed           Did not Enjoy             Total
Males             47                    13                           60
Females         53                      3                           56
Total             100                    16                         116 

                    Enjoyed                Did not Enjoy             Total
Males             47/116 = 0.41       13/116 = 0.11             60/116 = 0.52
Females         53/116 = 0.45         3/116 = 0.03             56/116 = 0.48
Total             100/116 =0.86        16/116 = 0.14           116/116 = 1.00
<span>
I'm not sure where a and b should be but based on the table: it can a = 41% ; b = 3% or a = 47% or b = 3%</span>
