after the equal employment opportunity commission (eeoc) completes its investigation in an employment discrimination case, _____.'.
After the EEOC completes its investigation in an employment discrimination case, the outcomes can include resolution attempts, lawsuits, or issuing a Notice of Right to Sue to the complainant.
After the Equal Employment Opportunity Commission (EEOC) completes its investigation in an employment discrimination case, several outcomes are possible:
The EEOC may find reasonable cause to believe that discrimination has occurred. In this case, they may attempt to resolve the matter through informal methods such as mediation or settlement negotiations. If these efforts fail, the EEOC may file a lawsuit against the employer on behalf of the aggrieved individual(s).
If the EEOC does not find reasonable cause, they will issue a Notice of Right to Sue to the individual who filed the complaint. This allows the individual to pursue a lawsuit against the employer independently.
In some cases, the EEOC may determine that further investigation is needed, and they may request additional information or evidence from both the complainant and the employer.

A spherical ball of ice has a diameter of 5 centimeters. How long will it take the ice ball to melt if it melts at a rate of 2.5 cubic centimeters per minute? Round to the nearest minute.
The ice ball will take about 26 minutes to melt completely.we get approximately 26.18 minutes.
To calculate the time it takes for the spherical ice ball to melt, we need to determine its volume and divide it by the melting rate.
The volume of a sphere can be calculated using the formula V = (4/3)πr^3, where V represents the volume and r represents the radius of the sphere. In this case, we are given the diameter of the ice ball, which is 5 centimeters. The radius (r) is half the diameter, so r = 5/2 = 2.5 centimeters.
Substituting the radius into the volume formula, we get V = (4/3)π(2.5)^3.
Calculating this, we find that the volume of the ice ball is approximately 65.45 cubic centimeters.
Next, we divide the volume by the melting rate of 2.5 cubic centimeters per minute to find the time it takes to melt:
Time = Volume / Melting rate = 65.45 / 2.5.
Calculating this, we get approximately 26.18 minutes.
Rounding to the nearest minute, the ice ball will take about 26 minutes to melt completely.
It's important to note that this calculation assumes a constant melting rate throughout the melting process. In reality, the melting rate may vary due to factors such as temperature fluctuations. Additionally, this calculation does not take into account factors like the insulating properties of ice or external factors that may affect the melting rate.

A triangle ABC with three different side lengths had the longest side AC and shortest AB. If the perimeter of ABC is 384 units, what is the greatest possible difference between AC-AB?
Hence, the greatest possible difference between AC and AB is -2 units.
Let's denote the lengths of the three sides of the triangle as AB, BC, and AC.
Given that AC is the longest side and AB is the shortest side, we can express the perimeter of the triangle as:
Perimeter = AB + BC + AC = 384 units
To find the greatest possible difference between AC and AB, we want to maximize the value of (AC - AB). Since AC is the longest side and AB is the shortest side, maximizing their difference is equivalent to maximizing the value of AC.
To find the maximum value of AC, we need to consider the remaining side, BC. Since the perimeter is fixed at 384 units, the sum of the lengths of the two shorter sides (AB and BC) must be greater than the length of the longest side (AC) for a valid triangle.
Let's assume that AB = x and BC = y, where x is the shortest side and y is the remaining side.
We have the following conditions:
AB + BC + AC = 384 (perimeter equation)
AC > AB + BC (triangle inequality)
Substituting the values:
x + y + AC = 384
AC > x + y
From these conditions, we can infer that AC must be less than half of the perimeter (384/2 = 192 units). If AC were equal to or greater than 192 units, the sum of AB and BC would be less than AC, violating the triangle inequality.
Therefore, to maximize AC, we can set AC = 191 units, which is less than half the perimeter. In this case, AB + BC = 384 - AC = 193 units.
The greatest possible difference between AC and AB is (AC - AB) = (191 - 193) = -2 units.

So, what is the pattern? For positive integers a and b: (x^a)^b
Answer: (x^b)^a
Step-by-step explanation:
the inverse of a monomial with an exponent raised to another power will give the same product if you flip the exponents.
Here we have a general rule for exponents.
We will find that:
\((x^a)^b = x^{a*b}\)
To get this, we can first check it with some values for the exponents.
a = 2
b = 3
\((x^2)^3 = (x^2)*(x^2)*(x^2) = (x*x)*(x*x)*(x*x) = x^6 = x^{2*3}\)
Similarly, we can prove it for two general values of a and b:
\((x^a)^b = (x^a)*(x^a)*...*(x^a)\\b\ times\)
Now each one of these parentheses has a multiplying by itself a times.
So when we write all the x's, we will see that there are a total of b*a x's
Thus we will have:
\((x^a)^b = (x^a)*(x^a)*...*(x^a) = x^{a*b}\)

Which multiplication expression can you use to find 3/8÷3/4
The multiplication expression that can be used to find 3/8 ÷ 3/4 is 3/8 * 4/3, and the simplified result is 1/2.
To find the division of fractions, we can multiply the first fraction by the reciprocal of the second fraction.
In this case, we want to find 3/8 ÷ 3/4.
The reciprocal of a fraction is obtained by flipping the numerator and denominator.
So, the reciprocal of 3/4 is 4/3.
To find the division, we multiply the first fraction by the reciprocal of the second fraction:
3/8 ÷ 3/4 = 3/8 \(\times\) 4/3
Now, let's simplify this multiplication expression.
We can cancel out any common factors between the numerators and denominators:
3/8 \(\times\) 4/3 = (3 \(\times\) 4) / (8 \(\times\) 3) = 12/24
Further simplification can be done by dividing both the numerator and denominator by their greatest common divisor, which in this case is 12:
12/24 = (12 ÷ 12) / (24 ÷ 12) = 1/2
Therefore, the multiplication expression that can be used to find 3/8 ÷ 3/4 is 3/8 \(\times\) 4/3, and the simplified result is 1/2.
In conclusion, to divide 3/8 by 3/4, we can use the multiplication expression 3/8 \(\times\) 4/3, which simplifies to 1/2.

an inner city revitalization zone is a rectangle that is twice as long as it is wide. the width of the region is growing at a rate of 31 m per year at a time when the region is 450 m wide. how fast is the area changing at that point in time?
The area of the rectangle is increasing at a rate of 27,900,000 meters³ per year when the width of the region is 450 meters.
The inner-city revitalization region is a rectangle that is twice as long as it is wide. At a time when the area is 450 meters wide, the width of the region is increasing at a rate of 31 meters per year. The aim is to find out how quickly the area is changing at this point in time. The area of the rectangle is given by the formula,
Area = length × width
Given that the width of the rectangle is increasing at a rate of 31 meters per year. Let's say the width of the rectangle is w meters, and the rate of change in width is dw/dt meters per year. Then, we can say, dw/dt = 31 meters per year
Width of the rectangle is w meters
Length of the rectangle is twice the width, or 2w meters
Area of the rectangle is given by the formula, A = lw= 2w × w= 2w²
Now, we need to find dA/dt, the rate at which the area of the rectangle is changing with respect to time (t).We can find it using the formula,
dA/dt = dA/dw × dw/dt
dA/dw = 4w (differentiate 2w² with respect to w)
dw/dt = 31 meters per yeard
A/dt = dA/dw × dw/dt= 4w × 31= 124w meters² per year
From the given information, the width of the rectangle is 450 meters wide. So, the width is w = 450 meters.
dA/dt = 124w meters² per year
= 124 × 450 meters² per year
= 27,900,000 meters³ per year

A water tank at Camp Newton holds 1200 gallons of water at time t = 0. During the time interval Osts 18 hours, water is pumped into the tank at the rate
W(t) = 95Vt sin^2 (t/6) gallons per hour During the same time interval water is removed from the tank at the rate R(t) = 275 sin^2 (1/3) gallons per hour a. Is the amount of water in the tank increasing at time t = 15? Why or why not?
b. To the nearest whole number, how many gallons of water are in the tank at time t = 18? c. At what time t, for 0 st 18, is the amount of water in the tank at an absolute minimum? Show the work that leads to your conclusion d. For t > 18, no water is pumped into the tank, but water continues to be removed at the rate R(C) until the tank becomes empty. Write, but do not solve, an equation involving an integral expression that can be used to find the value of k.
(a)The amount of water in the tank is increasing.
(b)Evaluate \(\int\limits^{18}_0(W(t) - R(t)) dt\) to get the number of gallons of water in the tank at t = 18.
(c)Solve part (b) to get the absolute minimum from the critical points.
(d)The equation can be set up as \(\int\limits^k_{18}-R(t) dt = 1200\) and solve this equation to find the value of k.
What is the absolute value of a number?
The absolute value of a number is its distance from zero on the number line. It represents the magnitude or size of a real number without considering its sign.
To solve the given problems, we need to integrate the given rates of water flow to determine the amount of water in the tank at various times. Let's go through each part step by step:
a)To determine if the amount of water in the tank is increasing at time t = 15, we need to compare the rate of water being pumped in with the rate of water being removed.
At t = 15, the rate of water being pumped in is given by \(W(t) = 95Vt sin^2(\frac{t}{6})\) gallons per hour. The rate of water being removed is \(R(t) = 275 sin^2(\frac{1}{3})\) gallons per hour.
Evaluate both rates at t = 15 and compare them. If the rate of water being pumped in is greater than the rate of water being removed, then the amount of water in the tank is increasing. Otherwise, it is decreasing.
b) To find the number of gallons of water in the tank at time t = 18, we need to integrate the net rate of water flow from t = 0 to t = 18. The net rate of water flow is given by the difference between the rate of water being pumped in and the rate of water being removed. So the integral to find the total amount of water in the tank at t = 18 is:
\(\int\limits^{18}_0(W(t) - R(t)) dt\)
Evaluate this integral to get the number of gallons of water in the tank at t = 18.
c)To find the time t when the amount of water in the tank is at an absolute minimum, we need to find the minimum of the function that represents the total amount of water in the tank. The total amount of water in the tank is obtained by integrating the net rate of water flow over the interval [0, 18] as mentioned in part b. Find the critical points and determine the absolute minimum from those points.
d. For t > 18, no water is pumped into the tank, but water continues to be removed at the rate R(t) until the tank becomes empty. To find the value of k, we need to set up an equation involving an integral expression that represents the remaining water in the tank after time t = 18. This equation will represent the condition for the tank to become empty.
The equation can be set up as:
\(\int\limits^k_{18}-R(t) dt = 1200\)
Here, k represents the time at which the tank becomes empty, and the integral represents the cumulative removal of water from t = 18 to t = k. Solve this equation to find the value of k.

Matrix Metro is a city with m rows and n columns of buildings, with roads connecting these houses to form a grid. Amy is visiting and wants to walk around the city. Help Amy find the length of the longest path that she can walk (i.e. she never walks to the same building twice). Provide a brief explanation as to why it is the maximum. You can assume m, n >= 2.
The longest path that Amy can walk in Matrix Metro is equal to min(m,n)*2-1.
To see why, imagine that Amy starts at any building in the city. Without loss of generality, let's assume she starts at the bottom left corner of the city.
From this point, she has two options: continue walking to the right or turn up. If she continues walking to the right, she will eventually reach the rightmost column of the city and will have to turn up.
Since Amy cannot visit the same building twice, she can visit at most min(m,n) buildings in each row or column. If she visits all min(m,n) buildings in each row or column, she will visit a total of 2*min(m,n) - 1 buildings.
Therefore, the length of the longest path that Amy can walk in Matrix Metro is min(m,n)*2-1, and this is the maximum because Amy cannot visit any more buildings without visiting the same building twice.
