The fourth step of the risk assessment process is to determine current level of preparedness/mitigation.

The correct option is C.

A risk assessment is a procedure for identifying potential dangers and analyzing what might happen if one happens. A business impact analysis (BIA) is a procedure that determines the probable consequences of interrupting time-sensitive or important business processes. There are various potential hazards to be mindful of.

The ultimate goal of risk assessments is to improve workplace safety and health. However, to order to accomplish this, your risk assessment process must identify occupational hazards and eliminate or reduce the risks they represent.

Answer:

x is 50.

Explanation:

3.5 and 1.4 are both at the bottom of the fraction (denominators), so divide 3.5 by 1.4 to get 2.5.

Then, multiply 20 by 2.5.

This makes sense because 3.5 is greater than 1.4, and the final answer (50) is greater than 20.

We can always check by dividing 50 by 3.5 and 20 by 1.4. See if it is the same number.

Given in the picture that [tex]D=b^{2} -4ac[/tex]. and the value of Quadratic equation is  [tex]b=\sqrt{65}[/tex].

(a) Express b in terms of a, c and D.

[tex]b=\sqrt{D-4ac}[/tex]

(b) Find the values of b when a=2, c=-2 and D=81.

[tex]b=\sqrt{65}[/tex]

By seeing the question we can say that the [tex]b^{2} -4ac[/tex] is in the quadratic formula.

We know the general Quadratic Equation is [tex]ax^{2}+bx+c=0[/tex].

The solution to find the root of the Quadratic Equation is Quadratic Formula: [tex]\frac{-b\pm\sqrt{b^{2}-4ac } }{2a}[/tex].

The whole solution is depend on [tex]b^{2} -4ac[/tex]. The team is called discriminant.

(a) Given that,

[tex]D=b^{2} -4ac[/tex]

[tex]b^{2}=D +4ac\\[/tex]

Taking square root on both sides.

[tex]\sqrt{b^{2} } =\sqrt{D+4ac}\\ b=\sqrt{D+4ac}\\[/tex]

Therefore, [tex]b=\sqrt{D-4ac}[/tex]

(b) Given that,

a=2,c=-2 and D=81

[tex]b=\sqrt{D+4ac}\\[/tex]

[tex]b=\sqrt{81+4(2)(-2)}\\[/tex]

[tex]b=\sqrt{81-16}[/tex]

[tex]b=\sqrt{65}[/tex]

Therefore, [tex]b=\sqrt{65}[/tex]

A quadratic equation is a second-degree algebraic equation in x. In its usual form, the quadratic equation is a[tex]x^2[/tex] + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant factor. The first requirement for an equation to be a quadratic equation is that the coefficient of [tex]x^2[/tex] is not zero (a 0). When expressing a quadratic equation in standard form, the [tex]x^2[/tex]term comes first, then the x term, and finally the constant term.

Step-by-step explanation:

Answer: c= 360/n

Step-by-step explanation:

c=k/n, for c=60 and n=6 so equation would be 360/n

denote by u¹ the first term

hence u⁹ is the 9th term

[tex]u_{n} = u_{1} + (n - 1)d[/tex]

[tex]u_{2} = 2 \: \: \: \: \: \: u_{6} = - 14 \\ u_{1} + (2 - 1)d = 2 \\ u_{1} + (6 - 1)d = - 14[/tex]

[tex]u_{1} + d = 2 \\ u_{1} + 5d = - 14 \\ \\ \: \: \: (u_{1},d)=(6,-4)[/tex]

[tex]u_{9} = u_{1} + (9 - 1)d \\ u_{9} = u_{1} + 8d \\ u_{9} = 6+ (8)( - 4) \: \\ u_{9} = - 26[/tex]

Answer:  a₁=6   a₉=-26

Step-by-step explanation:

a₂=2    a₆=-14    a₁=?     a₉=?

a₂=a₁+(2-1)d

a₆=a₁+(6-1)d

a₁+d=2    (1)

a₁+5d=-14  (2)

Subtract equation (1) from equation (2):

4d=-16

Divide both parts of the equation by 4:

d=-4

Hence,

a₁+(-4)=2

a₁-4+4=2+4

a₁=6

a₉=a₁+(9-1)d

a₉=6+8(-4)

a₉=6+(-32)

a₉=6-32

a₉=-26

If the distance,d, traveled by a particle is directly proportional to the square of the time,t, taken, when t = 40, d = 30, then the formula for d in terms of t will be d = 0.01875(t²).

Proportionality can be described as the property of being in a proper correlation in terms of size or quantity. In this problem, the distance is directly proportional to the square of the time which means that the distance increases as the square of the time is increased and vice versa.

Therefore,

d ∝ t²

d = kt² ( when t = 40 and d = 30 )

Here k is the constant

The value of k can be found by rearranging the equation,

d = kt²

30 = k(40²)

30 = k(1600)

k = 30 / 1600

k = 0.01875

As k = 0.01875, the formula for d in terms of t can be given as,

d = kt²

d = 0.01875(t²)

The unknown angles on the straight line are as follows:

∠RQT is a straight angle.

Therefore,

∠RQT = 180 degrees(angle on a straight line)

Therefore, let's find m∠RQS and m∠TQS

∠RQT = m∠RQS + m∠TQS

where,

m∠RQS = 10x + 9

m∠TQS = 7x + 1

Therefore,

∠RQT = 10x + 9 + 7x + 1

∠RQT = 17x + 10

180 - 10 = 17x

170 = 17x

divide both sides by 17

x = 170 / 17

x = 10

Therefore,

m∠RQS = 10(10) + 9 = 109°

m∠TQS = 7(10) + 1 = 71°

The answer of the given question will be - [tex]ln |n| + c = e^{8+t} t - e^{8+t} - t + c[/tex]

In mathematics, integration is a technique for combining or adding the parts to arrive at the total. It is a form of differentiation in reverse where we break down functions into their component elements. This technique is employed to determine the summation on a sizable scale.

We are given the equation as -

[tex]\int\limits^_ {}[/tex]dn/dt + n = [tex]\int\limits^_ {}[/tex][tex]nte^{t+8}[/tex]

⇒ dn/dt = [tex]nte^{t+8} - n[/tex]

[tex]dn/dt = n(te^{t+8} - 1)\\dn/n = (te^{t+8} - 1)dt[/tex]

Integrating on both sides,

⇒ ln |n| + c =[tex]\int\limits^[/tex][tex]nte^{t+8} - n[/tex]

⇒ ln |n| + c = [tex]e^{8+t} t - e^{8+t} - t + c[/tex]

Answer:

1.h=7; 2. A=78.5; 3. h=3; 4. h=8; 5. I=5.

Step-by-step explanation:

1. A = bh for h, if b = 4 and A = 28

So 28=4h then we divided both side by 4 to get the value of h , h=7.

2. A = πr2 for A, if r = 5.

So A=3.14×25=78.5.

3. A = bh for h if b = 15 and A = 45. h=?

So 45=15h then we divided both side by 15 to get the value of h , h=3.

4. A = bh for h if b = 10 and A = 80. h=?

So 80=10h then we divided both side by 10 to get the value of h , h=8.

5.P = 2l + 2w for l if w = 4 and P = 18. l=?

So 18=2I + 2(4) =18-8=2I 10=2l then to get the value of I divided both side by 2, I=5.
