A. Lockout Tagout. The lockout keeps you or anyone else from reconnecting it and if you go to leave it will be safe until done

Solution:

1. Lockout/Tagout :(LOTO)  it is a type of program embed in electrical equipment which is used in different industries that when you will open that kind of device or repair it you should first disconnect it completely from its electrical source. Then you have to make sure that the electricity cannot be reconnected by you or anyone else until it is safe again.

2. Over Current Protection: If extra current is flowing in the circuit ,to stop it we use over current protection like fuses, relays etc.

3. Shocking Current: If any part of human is touched to the part of wire without lid or the electrical equipment which is not fully protected through which current is flowing through it there is a chance of Shock.If power is very high there is chance of damage or that part of your body may not work.

4. Shut Down: When current is flowing through an electrical device ,when that device is turned off i.e leakage is called shut down current.

Option (A)  Lockout/Tagout, is correct Safety measure for above situation.

Solve the following maximization problem graphically.
rjkz [21]

The maximized value of the function is (c) 119/2

<h3>Maximization problem</h3>

Maximization problems are used to determine the optimal solution of a linear programming model

<h3>Objective function</h3>

The objective function is given as:

P(x,y) = 11x + 10y

<h3>Constraints</h3>

The constraints are given as:

22x + 2y \le 68

8x + 16y \le 68

x,y\ge 0

<h3>Graph</h3>

See attachment for the graph of the constraints

From the graph, the optimal solution is: (2.83, 2.83)

So, the maximized value is:

P(x,y) = 11x + 10y

P =11 \times 2.833 + 10 \times 2.833

P =59.493

Approximate

P =59.5

Rewrite as a fraction

P =\frac{119}{2}

Hence, the maximized value of the function is (c) 119/2

3 squares are positioned to form a triangle. the small square is labeled 6 units, medium square is 8 units, and large square is
LuckyWell [14K]

The area of the square of the leg 6 is 36 square units.

The area of the square of the leg 8 is 64 square units.

The area of the square of the hypotenuse square is 100 square units.

The length of the hypotenuse is 10 units.

Formula Used

Area of square, A = (a)^{2}

Here, a is the length of the side of the square.

Pythagoras Theorem is given as,

h^{2} =p^{2} +b^{2}

Here, h, p, b are the hypotenuse, perpendicular, and the base of a right angle triangle respectively.

Area of the Square of the Leg 6

Length of the edge of the square = 6 units

Area of square = 6*6

= 36 square units

Area of the Square of the Leg 8

Length of the edge of the square = 8 units

Area of square = 8*8

= 64 square units

Area of the Hypotenuse Square and the Length of the Hypotenuse

Applying Pythagoras theorem,

h^{2} = (8)^{2} +(6)^{2}

h^{2} = 64+36

h = \sqrt{100}

h = 10 units

Therefore, the area of the hypotenuse square is 100 square units and the length of the hypotenuse comes out to be10 units.
