Answers

Answer 1
Answer:

Answer:

The correct answer to the following question will be Option A (67.9%).

Step-by-step explanation:

As we know,

The number of total employees will be:

= 480

The number of employees having normal or low BP will be:

= 96 + 230

= 326

Hence, the percentage of low or normal BP workers will be:

= ((326)/(480) )* 100 \ percent

= 67.9 \ percent

Note:- % (percent)

How many fixed points are there for the function f(x)=x^4

Answers

The fixed points in the function f(x) = x^4 are:

x = 0, x = 1, x = -0.5 - 0.866i, and x = -0.5 +0.866i

The given function is:

f(x) = x^4

The fixed points of a function f(x) is determined by solving f(x) - x = 0

x^4 - x = 0\nx(x^3-1) = 0\nx(x-1)(x^2+x+1) = 0

Equate each of the terms to zero:

x  =  0

x  - 1  =  0

x  =  1

x^2+x+1 = 0\n\nx = (-b\pm √(b^2-4ac) )/(2a) \n\nx = (-1\pm √(1^2-4(1)(1)) )/(2(1)) \n\nx = (-1\pm √(-3) )/(2)\n\nx= (-1\pm i√(3) )/(2)\n\nx = (-1 \pm i√(3) )/(2)\n\nx= -0.5\pm0.866i\n\nx_1 = -0.5-0.8661\n\nx_2 = -0.5+0.866i

Therefore, the fixed points in the function f(x) = x^4 are:

x = 0, x = 1, x = -0.5 - 0.866i, and x = -0.5 +0.8661

Triangle RST has the vertices R(2, 3), S(-2, 1), and T(-1, 5). What are the coordinates after the two transformations: Translation (x, y) --> (x - 2, y - 1) Rotation: 90 degrees counterclockwise at the origin.Immersive Reader

Answers

Given :

Triangle RST has the vertices R(2, 3), S(-2, 1), and T(-1, 5).

To Find :

The coordinates after the two transformations:

a) Translation (x, y) --> (x - 2, y - 1) .

b)  Rotation: 90 degrees counterclockwise at the origin.

Solution :

Applying transition a) , we get :

R'(2-2,3-1) , S'(-2-2,1-1) , T'(-1-2,5-1)

R'( 0, 2) , S'( -4 , 0), T'( -3, 4)

Now , When any point ( h , k ) is rotated 90° counterclockwise about the origin, the new points are (-k , h) .

So , R''( -2, 0) , S''( 0, -4 ) , T''( -4 , -3 ) .

Therefore , the coordinates after transformations are

( -2, 0) ,( 0, -4 ) , ( -4 ,-3 ) .

Hence , this is the required solution .

What is the remainder of 525 divided by 28? as a whole number

Answers

The remainder of 525 divided by 28 is 21

First step

Division

525 ÷ 28

= 18

Second step multiply 28 by 18

28 × 18

= 504

Now let determine remainder of 525 divided by 28

Remainder=525 - 504

Remainder= 21

Inconclusion remainder of 525 divided by 28 is 21

Answer:

R = 21

Step-by-step explanation:

525 ÷ 28 = 18 R 21

28 × 18 = 504

525 - 504 = 21

Therefore, the remainder is 21.
