If f(x) = 1 – x, which value is equivalent to |f(i)|?

lukranit [14]

Determine which value is equivalent to | f ( i ) | if the function is: f ( x ) = 1 - x. We know that for the complex number: z = a + b i , the absolute value is: | z | = sqrt( a^2 + b^2 ). In this case: | f ( i )| = | 1 - i |. So: a = 1, b = - 1. | f ( i ) | = sqrt ( 1^2 + ( - 1 )^2) = sqrt ( 1 + 1 ) = sqrt ( 2 ). ANSWER IS C. sqrt( 2 )

Evaluate the given integral by changing to polar coordinates.∫∫ x2y dA, where D is the top half of the disk with center the orig

amid [387]

Answer:

Required value is $\frac{1250}{3}$ .

Step-by-step explanation:

We have to find the value of,

$\int\int_{D} x^2y dA\hfill (1)$

where, $D=\{(5,\theta) : 0\leq r\leq 5, 0\leq \theta \leq \pi \}$

To convert it in polar form let $x=r\cos\theta, y=r\sin\theta$ and substitute in (1) we get,

$\int\int_{D} x^2y dA$

$=\int_{0}^{\pi}\int_{0}^{5}(r\cos\theta)^2(r\sin\theta)rdrd\theta$

Assuming,

$u=\cos \theta$ then,

$du=-\sin\theta d\theta\implies-du=\sin\thetad\theta[tex]For [tex]\theta=0, u=1$ and $\theta=\pi$ gives u=-1. Hence,

$\int\int_{D} x^2y dA$

$=\int_{0}^{\pi}\int_{0}^{5}(r\cos\theta)^2(r\sin\theta)rdrd\theta$

$=\int_{1}^{-1}u^2(-du)\int_{0}^{5}r^4dr$

$=\int_{-1}^{1}u^2du\int_{0}^{5}r^4dr$

$=\Big[\frac{u^3}{3}\Big]_{-1}^{1}\times\Big[\frac{r^5}{5}\Big]_{0}^{5}$

$=\frac{2\times 5^4}{3}=\frac{1250}{3}$

Jeffery babysits for 4 dollars per hour, he also works as a math tutor for 7 dollars per hour. He is only allowed to work 13 hou

Oksana_A [137]

Given:

Jeffery babysits for 4 dollars per hour and works as a math tutor for 7 dollars per hour.

He is only allowed to work 13 hours total per week.

He wants to make at least 65 dollars.

To find:

The system of inequalities to represent this situation.

Solution:

Let x be the number of hours he babysits per week and y be the number of hours h works as a math tutor.

He is only allowed to work 13 hours total per week. It means sum of x and y must be less than or equal to 13.

$x+y\leq 13$

He wants to make at least 65 dollars. It means total earnings must be greater than or equal to 65.

$4x+7y\geq 65$

Number of hours can not be negative.

$x\geq 0, y\geq 0$ .

Therefore, the required system of inequalities contains some equations, $x+y\leq 13,4x+7y\geq 65$ and $x, y\geq 0$ .
