A warehouse worker wearing a dosimeter has recorded the following noise level data: Station 1: 82 dBA at 3.5 hours Station 2: 97 dBA at 1.5 hour Station 3: 85 dBA at 2 hours Using Table of Equivalent values: Steady Sound Level (dBA) Duration 82 16 hours 85 8 hours 88 4 hours 91 2 hours 94 1 hours 97 30 minutes 100 15 minutes 103 7.5 minutes 106 3.75 minutes 109 1.88 minutes 112 0.94 minutes 115 28.12 seconds Determine the percentage exposure. Is it within the OEL value? Explain
The percentage exposure needs to be calculated by converting the duration of each noise level and comparing it to the OEL (Occupational Exposure Limit) value to determine if it is within the acceptable range.
The percentage exposure is [to be calculated]. It needs to be compared to the OEL (Occupational Exposure Limit) value to determine if it is within the acceptable range.
In order to calculate the percentage exposure, we need to convert the duration of each noise level into hours and sum them up. For Station 1, the duration is 3.5 hours, for Station 2 it is 1.5 hours, and for Station 3 it is 2 hours. We can then use the table of equivalent values to find the corresponding steady sound levels and their durations. By multiplying each steady sound level by its duration and summing them up, we can calculate the total exposure.
Once we have the total exposure, we can compare it to the OEL value, which represents the maximum allowable exposure. If the percentage exposure is within the OEL value, it means that the worker's exposure to noise is within the acceptable limit. If the percentage exposure exceeds the OEL value, it indicates that the worker has been exposed to noise levels that exceed the recommended limit, which may have potential health and safety implications.

A bag contains 99 marbles, some white and some red. The ratio of white marbles to red ones is 5:4. how many white marbles are there?
Answer:
55 white
Step-by-step explanation:
So ratio 5:4 is essentially saying, for each 5 white marbles, there are 4 red ones. This can be represented in the equation: 5x+4x=99. We specifically want an integer solution. Because what is 1.2 of a marble? And what is -1 marbles? So as x increases by 1, the entire thing increases by 9. This gives you the equation: 9x=99 which gives you x=11. So there are 55 white and 44 red.

A little league baseball team is ordering hats. The graph shows the relationship between the total cost, in dollars, and the number of hats ordered.
What does the slope of the graph tell us in this situation?
The slope tells us that the cost increases as the number of ordered hats increases.
Given,
A little league baseball team is ordering hats.
The graph shows the relationship between the total cost, in dollars, and the number of hats ordered.
We need to find out what the slope of the graph tells us in this situation.
What is the slope of a graph?The slope in a graph tells us the relationships between the data on the x-axis and the y-axis.
The points on the slope give the relationships between the particular point on the x-axis and the y-axis.
The slope tells us the rate of change of y relative to x.
We see that,
If the number of orders of hats is 1, the total cost is $50.
1 order = $50
Similarly,
2 order = $60
3 order = $80
4 order = $90
5 order = $100
6 order = $120
7 order = $130
8 order = $150
9 order = $160
10 order = $170
11 order = $190
We see that as the order of hats increases the cost also increases.
Thus the slope tells us that the cost increases as the number of ordered hats increases.

Answer:
8. m∠5 = 160°; m∠8 = 20°
9. BH = 10; CH = 20
10. m∠GBC = 90°
Step-by-step explanation:
8.
Finding m∠5:
Angles 1 and 5 are corresponding angles which means they are congruent and have the same measure.Thus, since m∠1 = m∠5 and m∠1 = 160°, m∠5 also = 160°,
Finding m∠8:
We see that angle 8 is an exterior angle while angle 5 is an interior angle.When an exterior and interior angle lie on the same side of a transversal but on opposite sides of one of the parallel lines, they are supplementary, which means the sum of their measures is 180°.Angles 8 and 5 lie on the same side of the traversal t, but on opposite sides of the parallel line n, which means they're supplementary.Since m∠5 = 160°, we can find m∠8 by subtracting 160 from 180:
m∠5 + m∠8 = 180
m∠8 = 180 - m∠5
m∠8 = 180 - 160
m∠8 = 20
Thus, m∠8 = 20°.
9.
Finding BH and CH:
A perpendicular bisector splits a triangle into two equal parts and creates two right angles beside each other in both parts.BH:
The bisector split side GH entirely which means BG and BH equal each other.Since BG's length is 10, BH's length is also 10.
CH:
Since a perpendicular bisector creates two equal halves/parts, the lengths of CG and CH are equal.Since CG's length is 20, CH's length is also 20.
10.
Finding ∠GBC:
Sine a perpendicular creates two right angles beside each other, the two right angles are angles GBC and HBC.Since the measure of a right angle is 90°, m∠GBC = 90°.

solve the following equation, giving only the solutions which lie in [0, 2????). express the exact solutions using inverse trigonometric functions. (if there is no solution, enter no solution.) tan(x)
The solutions to the equation tan(x) = 0 within the interval [0, 2π) are x = 0 and x = 2π. To solve the equation tan(x) = 0 within the interval [0, 2π), we can consider the properties of the tangent function and its periodicity.
The tangent function is defined as the ratio of the sine and cosine functions: tan(x) = sin(x)/cos(x).
First, we note that tan(x) is equal to 0 when sin(x) = 0 and cos(x) ≠ 0. This occurs when x is an integer multiple of π.
In the given interval [0, 2π), the solutions for tan(x) = 0 are x = 0, π, and 2π.
However, we need to consider that the tangent function has vertical asymptotes at x = π/2 and 3π/2, where the cosine function is equal to zero. Therefore, the values x = π/2 and 3π/2 are not solutions within the given interval [0, 2π).
So, the solutions that lie within the interval [0, 2π) and satisfy tan(x) = 0 are x = 0 and x = 2π.

ROC of a causal LTI system expressed using the transfer function = {s: Re(s) < 14}. Hence, the correct option is the first one.
transfer function is
H(s) = (s+1) (s²-28+5) (8+4) (8-3)(8²+4) H (8) S
Given H(s) is a product of polynomial factors. For each factor of the polynomial, calculate the poles of H(s).
The ROC is the intersection of all ROCs of all factors of H(s). Calculate the poles of H(s). Poles of H(s) are:
s = -1, s = 14±3j, and s = ±2jPoles of H(s) are located at -1 (a finite pole), 14±3j, and ±2j.
All the poles of H(s) lie on the left half of the s-plane (i.e., it is a causal system).
Thus, the ROC of H(s) will include the left half of the s-plane and may or may not include the imaginary axis. Therefore, ROC is:
ROC = {s: Re(s) < 14} or ROC = {s: -∞ < Re(s) < 14}
The Region of Convergence is all of the left-hand plane except for a finite region around the pole at s = -1.

Rotating shapes about the origin by multiples of 90°
Learn how to draw the image of a given shape under a given rotation about the origin by any multiple of 90°.
Introduction
In this article we will practice the art of rotating shapes. Mathematically speaking, we will learn how to draw the image of a given shape under a given rotation.
This article focuses on rotations by multiples of 90^\circ90∘90, degrees, both positive (counterclockwise) and negative (clockwise).
Part 1: Rotating points by 90^\circ90∘90, degrees, 180^\circ180∘180, degrees, and -90^\circ−90∘minus, 90, degrees
Let's study an example problem
We want to find the image A'A′A, prime of the point A(3,4)A(3,4)A, left parenthesis, 3, comma, 4, right parenthesis under a rotation by 90^\circ90∘90, degrees about the origin.
Let's start by visualizing the problem. Positive rotations are counterclockwise, so our rotation will look something like this:
yyxxA'A′\blueD{A(3,4)}A(3,4)
Cool, we estimated A'A′A, prime visually. But now we need to find exact coordinates. There are two ways to do this.

What is the formula for the indicated variables? A-lw wh + lh, for w
Hello there. To solve this question, we have to remember some properties about solving equations for a variable.
Given the following equation:
\(A=lw+wh+lh\)We want to solve it for w.
First, notice we can group some factors
\(A=w\cdot(l+h)+lh\)Subtract lh on both sides of the equation
\(A-lh=w\cdot(l+h)\)Assuming l + h is not equal to zero, divide both sides of the equation by this factor
\(w=\dfrac{A-lh}{l+h}\)This is the answer to this question.

Answer:
∠ JHF = 69°
Step-by-step explanation:
Since HJ is a midline then it is parallel to EG , thus
∠ JHF and ∠ GEH are corresponding and congruent, then
7x + 62 = 79 - 10x ( add 10x to both sides )
17x + 62 = 79 ( subtract 62 from both sides )
17x = 17 ( divide both sides by 17 )
x = 1
Thus
∠ JHF = 7x + 62 = 7(1) + 62 = 7 + 62 = 69°
Answer:
7x + 62 = 180
7x= 180 - 62
x = 118 / 7
x = 16
7 × x = 7 × 16

Find the product of d = ba. d11 = d12 = d21 = d22 =
Given d = ba, we can write:
d11 = b1a1 + b2a3
d12 = b1a2 + b2a4
d21 = b3a1 + b4a3
d22 = b3a2 + b4a4
To find the product of d, we need to find the values of b and a such that d11 = d12 = d21 = d22.
Let's assume that d11 = d12 = d21 = d22 = x. Then, we have:
b1a1 + b2a3 = x
b1a2 + b2a4 = x
b3a1 + b4a3 = x
b3a2 + b4a4 = x
We can solve for b1, b2, b3, and b4 in terms of a1, a2, a3, and a4:
b1 = (x - b2a3)/a1
b2 = (x - b1a1)/a3
b3 = (x - b4a3)/a1
b4 = (x - b3a1)/a3
Substituting these values of b1, b2, b3, and b4 into the equation d = ba, we get:
d11 = x = a1(x - b1a3)/a1 + a3(x - b2a1)/a3
= x - b1a3 + x - b2a1
= 2x - (b1a3 + b2a1)
d12 = x = a2(x - b1a3)/a1 + a4(x - b2a1)/a3
= (a2/a1)x - (b1a2 + b2a4) + (a4/a3)x - (b1a4 + b2a4)
= x - (b1a2 + b2a4)
d21 = x = a1(x - b3a3)/a1 + a3(x - b4a1)/a3
= (a1/a1)x - (b3a3 + b4a3) + (a3/a3)x - (b3a1 + b4a3)
= x - (b3a1 + b4a3)
d22 = x = a2(x - b3a3)/a1 + a4(x - b4a1)/a3
= (a2/a1)x - (b3a2 + b4a4) + (a4/a3)x - (b3a4 + b4a4)
= x - (b3a2 + b4a4)
We can rewrite these equations in matrix form as:

find nonzero 2x2 matrices a and b such that ab=0
It is worth noting that there are many other possible choices for a and b that satisfy ab=0. This is because there are many ways to construct matrices with a row or column of zeros, and many ways to choose the nonzero entries in the other positions.
To find nonzero 2x2 matrices a and b such that ab=0, we need to find matrices a and b whose product is the zero matrix. A matrix multiplication is a combination of dot products between rows and columns of the two matrices. In order for the product of two matrices to be zero, one or both of the matrices must have a row of zeros or a column of zeros.
One way to construct such matrices is to set one of the matrices to have a row of zeros and the other to have a column of zeros. Let a be a matrix with a row of zeros and b be a matrix with a column of zeros, but with a nonzero entry in a different position. For example, we could choose:
a = [0 0; 1 0]
b = [0 1; 0 0]
Then, the product ab is:
ab = [0 0; 1 0] * [0 1; 0 0] = [0 0; 0 0]
So, we have found two nonzero 2x2 matrices a and b such that ab=0.
It is worth noting that there are many other possible choices for a and b that satisfy ab=0. This is because there are many ways to construct matrices with a row or column of zeros, and many ways to choose the nonzero entries in the other positions.
