Answer:

option A

Step-by-step explanation:

conversion of 3/16 using long division method.

in this method, we write dividend in the box and the divisor on the left side and quotient on the right side.

in the given division 3 is dividend 16 is divisor and 0.1875 is the quotient

the diagram attached below shows the long division

hence the correct answer is option A.

Select the two values of x that are roots of this equation. 2x2 + 11x - 6 = 0

sukhopar [10]

Answer:

2×2 +11x - 6 =0

4 + 11x - 6 = 0

11x - 6 =4

-6 + 4 = 11x

-2 = 11x

X =11/2

Write an expression for the calculation the difference of the products of 5 and 2 and 5 and 1

oee [108]

Let's review the terminology. A product is what you get when you multiply two numbers. So, the product of 5 and 2 is basically "5*2," and the product of 5 and 1 is "5*1."

The difference means when you subtract one from the other. So, the difference of 5*2 and 5*1 means "(5*2)-(5*1)". (Note: I put in parentheses to make sure the reader understands that 5*2 is separate from 5*1. 5*2-5*1 is confusing: you might not know what to do first!)

So, "(5*2)-(5*1)" can be your answer, OR you can simplify it further by actually doing the multiplication: "10-5". If you want the answer, just subtract--the expression is equal to 5.

Answer: "(5*2)-(5*1)" OR "10-5" OR "5"

John Davis makes $9.75 an hour. He works four hours on Monday, six hours on Tuesday, five hours on Wednesday, five hours on Thur

Hatshy [7]

You are given John Davis’ rate which is $9.75 an hour. It is said that he works for four hours on Monday, six hours on Tuesday, five hours on Wednesday, five hours on Thursday, and seven hours on Friday. You are asked to find the gross pay of John Davis. All you need to do is to multiply the rate to the hour of work.

Monday: $9.75(4h) = $39
Tuesday: $9.75(6h) = $58.5
Wednesday: $9.75(5h) = $48.75
Thursday: $9.75(5h) = $48.75
Friday: $9.75(7h) = $68.25

To get the gross pay, add everything and you will get $263.25. The answer is letter D.

Can I get help with finding the Fourier cosine series of F(x) = x - x^2

trapecia [35]

Assuming you want the cosine series expansion over an arbitrary symmetric interval $[-L,L]$ , $L\neq0$ , the cosine series is given by

$f_C(x)=\dfrac{a_0}2+\displaystyle\sum_{n\ge1}a_n\cos nx$

You have

$a_0=\displaystyle\frac1L\int_{-L}^Lf(x)\,\mathrm dx$
$a_0=\dfrac1L\left(\dfrac{x^2}2-\dfrac{x^3}3\right)\bigg|_{x=-L}^{x=L}$
$a_0=\dfrac1L\left(\left(\dfrac{L^2}2-\dfrac{L^3}3\right)-\left(\dfrac{(-L)^2}2-\dfrac{(-L)^3}3\right)\right)$
$a_0=-\dfrac{2L^2}3$

$a_n=\displaystyle\frac1L\int_{-L}^Lf(x)\cos nx\,\mathrm dx$

Two successive rounds of integration by parts (I leave the details to you) gives an antiderivative of

$\displaystyle\int(x-x^2)\cos nx\,\mathrm dx=\frac{(1-2x)\cos nx}{n^2}-\dfrac{(2+n^2x-n^2x^2)\sin nx}{n^3}$

and so

$a_n=-\dfrac{4L\cos nL}{n^2}+\dfrac{(4-2n^2L^2)\sin nL}{n^3}$

So the cosine series for $f(x)$ periodic over an interval $[-L,L]$ is

$f_C(x)=-\dfrac{L^2}3+\displaystyle\sum_{n\ge1}\left(-\dfrac{4L\cos nL}{n^2L}+\dfrac{(4-2n^2L^2)\sin nL}{n^3L}\right)\cos nx$
