Answer:

Total Cost = 29x + 0.32y

Step-by-step explanation:

It is 29x since you pay $29 per day, and x represents the number of days.

It is 0.32y since you pay $0.32 per mile, and y represents the number of miles.

Las dos cifras de un número suman 11 . Si las cifras se invierten de orden se invierten de orden , se obtiene otro número que ex

Alik [6]

Answer:

El número es el 47

Step-by-step explanation: Con los dígitos de los siguientes números se obtiene que su suma es 11

47 4 + 7 = 11

38 3 + 8 = 11

29 2 + 9 = 11

Si se cambia el orden de los dígitos:

47 se convierte en 74 74 - 47 = 27

38 " " 83 83 - 38 = 45

29 " " 92 92 - 29 = 63

Entonces el número solicitado es el 47

Which of the following inverse functions are defined for x = - 1/2? Select 4 of the following that apply. There must be 4 select

Finger [1]

Answer:

$y=cos^{-1}(x)$ ,

$y=cot^{-1}(-\frac{1}{2})$ ,

$y=sin^{-1}(-\frac{1}{2})$

$y=tan^{-1}(-\frac{1}{2})$

Above four functions are defined at the given point.

Step-by-step explanation:

We have been given all trigonometric function we need to tell which among them is defined for $x=-\frac{1}{2}$

Case 1: $y=cos^{-1}(x)$

Since, $At x=-\frac{1}{2}$

$y=cos^{-1}(-\frac{1}{2})$

$y=-cos^{-1}(\frac{1}{2})$

$y=\frac{2\pi}{3}$

Domain of the function is $[-1,1]$

Defined at given point.

Case 2: $y=cot^{-1}(-\frac{1}{2})$

$y=-cot^{-1}(\frac{1}{2})$

$y=-1.1071$

Domain of the function is $(-\infty,\infty)$

Defined at given point.

Case 3: $y=cosec^{-1}(-\frac{1}{2})$

$y=-cosec^{-1}(\frac{1}{2})$

Value of the function is not defined because it is out of the domain of the function.

Domain is $(-\infty,-1]\cup[1,\infty)$

So, not defined at given point.

Case 4: $y=sec^{-1}(-\frac{1}{2})$

$y=-sec^{-1}(\frac{1}{2})$

Value of the function is not defined because it is out of the domain of the function.

Domain is $(-\infty,-1]\cup[1,\infty)$

So, not defined at given point.

Case 5: $y=sin^{-1}(-\frac{1}{2})$

$y=-sin^{-1}(\frac{1}{2})$

$y=\frac{-\pi}{6}$

Domain of the function is $[-1,1]$

Defined at given point.

Case 6: $y=tan^{-1}(-\frac{1}{2})$

$y=-tan^{-1}(\frac{1}{2})$

$y=-0.4636$

Domain of the function is $(-\infty,\infty)$

Defined at given point.

Therefore, Option 1,2,5,6 are correct.

mylen [45]

Answer:

D. In scattering, long wavelengths are scattered the most.

Step-by-step explanation:

Scattering of light is the effect observed when there is an interaction between light energy and some particles. This occurs often in the earth's atmosphere which consists of different sizes of particles that interacts with the sunlight.

In scattering, light of shorter wavelengths are scattered by small sized particles compared to those with longer wavelengths. Example is the scattering of the sunlight by the atmospheric particles where colors with short wavelengths are scattered the most.

Arnold need to correct the statement; In scattering, long wavelengths are scattered the most. To read; In scattering, short wavelengths are scattered the most.
