What is the product of z1 and z2 if

MaRussiya [10]

Answer:

308[cos(45) + isin(45)]

Step-by-step explanation:

z1×z2:

Modulus: r1 × r2

= 7×44 = 308

Argument: theta1 + theta2

= -70 + 115 = 45

z1z2 = 308[cos(45) + isin(45)]

z1z2 = 154sqrt(2) + (i)154sqrt(2)

sqrt: square root

The data set represents the total number of pencils each student in a class needs to sharpen.

Firdavs [7]

Given:

The data set is:

0, 1, 1, 1, 2, 3, 4, 4, 6, 6, 9

To find:

The correct statement that represents the box plot of the data correctly.

Solution:

We have,

0, 1, 1, 1, 2, 3, 4, 4, 6, 6, 9

Divide the data in 2 equal parts.

(0, 1, 1, 1, 2), 3, (4, 4, 6, 6, 9)

Divide each parenthesis in 2 equal parts.

(0, 1), 1, (1, 2), 3, (4, 4), 6, (6, 9)

Here,

Minimum value = 0

First quartile = 1

Median = 3

Third quartile = 6

Maximum value = 9

A number line goes from 0 to 10. The whiskers range from 0 to 9, and the box ranges from 1 to 6. A line divides the box at 3.

Therefore, the correct option is D.

If f(x) = 5x − 3, which expression represents its inverse function?

tangare [24]

Answer:

$f ^{-1}(x)=\frac{x+3}{5}$

Step-by-step explanation:

To find the inverse of a function f (x) follow the steps below:

1) Make y = f (x)

$y= 5x - 3$

2) Solve for the variable x

$y+3= 5x - 3+3$

$y+3= 5x$

$x=\frac{y+3}{5}$

3) Exchange the variable x with the variable y

$y=\frac{x+3}{5}$

4) Make $y = f ^{-1}(x)$

$f ^{-1}(x)=\frac{x+3}{5}$

Finally, the inverse of the function f (x) is: $f ^{-1}(x)=\frac{x+3}{5}$
