=====================================================
Explanation:
This piecewise function is made of 3 separate functions of...
f(x) = 5 when \(-5 \le \text{x} \le -2\)
f(x) = 4 when \(-2 < \text{x} \le 3\)
f(x) = -3 when \(3 < \text{x} \le 6\)
--------
The interval \(-5 \le \text{x} \le -2\) turns into the interval notation [-5, -2]
Use square brackets to include each endpoint. Each endpoint is included because of the closed filled in points.
In contrast, the interval \(-2 < \text{x} \le 3\) has an open hole at -2 and so it turns into (-2, 3]
A similar situation happens with the interval \(3 < \text{x} \le 6\) to become (3, 6]
6. A family's income amount is $25,000. They budget out of their income:
Food: 20%
Shelter: 25%
Clothing: 15%
How much money is allotted for each of these items?
Food
Shelter
Clothing
Answer:
To find out how much money is allotted for each of these items, we can multiply the percentage of the income allocated to each item by the total income.
Food: 20% of $25,000 = $25,000 x 0.20 = $5000
Shelter: 25% of $25,000 = $25,000 x 0.25 = $6250
Clothing: 15% of $25,000 = $25,000 x 0.15 = $3750
So the family has $5000 for food, $6250 for shelter and $3750 for clothing.
Determine whether the series is convergent or divergent. 3^(n+1)4^-n If it is convergent, find its sum.
Geometric series is convergent if the |r|<1 where r is the common ratio.
Let Sn=∑ni=0(−3/4)i then
Sn=(−3/4)n+1−1(−3/4)−1
Now take n→∞ then
Sn→0−1(−3/4)−1=4/7
because |−3/4|<1 and so (−3/4)n→0. Now note that your sum is
lim ∑i=1n+1(−3)i−14i=lim 14∑i=1n+1(−3)i−14i−1=1/4.lim Sn=1/7.
Geometric series: A geometric series is the result of adding together geometric sequences indefinitely. Depending on the sequence given to us, such infinite sums can either be finite or infinite. A series is considered to be convergent if the partial sums gravitate to a certain value, also known as a limit. In contrast, a divergent series is one whose partial sums do not reach a limit. Divergent series frequently reach, reach, or avoid a particular number.

-2 1/4 = 2w
Answer:
\(w=-9/8\)
Step-by-step explanation:
We are given the equation \(-2 \frac{1}{4} = 2w\). To solve this equation, we can divide both sides by 2 to get that \(w = -2\frac{1}{4} \div 2 = -\frac{9}{8}\).
Answer:
w = - \(\frac{9}{8}\)
Step-by-step explanation:
Given
- 2 \(\frac{1}{4}\) = 2w ( change the mixed number to an improper fraction )
- \(\frac{9}{4}\) = 2w ( multiply both sides by 4 to clear the fraction )
- 9 = 8w ( divide both sides by 8 )

2. What is the difference between the input and the output of a function?
The input and the output of a function are key components in understanding how a function operates. The input refers to the value or values that are given to the function as an argument, while the output refers to the result or results that the function returns after processing the input.
In other words, the input is what you provide to the function, and the output is what you get in return. The input can be a single value or a set of values, depending on the requirements of the function. The output can also be a single value or a collection of values, again depending on the function's purpose.
It's important to note that the input and output of a function are not always the same. The function may perform calculations or transformations on the input, and the output may be different from the input. This transformation is what gives functions their ability to perform specific tasks and solve problems.
In summary, the input is what you give to a function, and the output is what you get in return after the function processes the input.

Let X represent the homework grades for students which are normally distributed with μ = 90 and σ = 2.
What is the probability for a randomly selected student to get a scores above a 92?
What is the probability for a randomly selected student to get a score between 88 and 92?
For a normally distributed variable X representing homework grades with a mean (μ) of 90 and a standard deviation (σ) of 2, the probability of a randomly selected student scoring above 92 can be calculated using the Z-score.
To find the probability of a randomly selected student scoring above 92, we first need to calculate the Z-score. The Z-score measures how many standard deviations an individual data point is from the mean. It is calculated using the formula Z = (X - μ) / σ, where X represents the value (92 in this case), μ is the mean (90), and σ is the standard deviation (2). Plugging in the values, we get Z = (92 - 90) / 2 = 1.
To calculate the probability of a score between 88 and 92, we repeat the process for both lower and upper limits. For the lower limit (88), we calculate the Z-score as Z = (88 - 90) / 2 = -1. Similarly, for the upper limit (92), the Z-score is 1 as calculated earlier. Using the standard normal distribution table or calculator, we find the area to the left of the Z-score of -1 and the area to the left of the Z-score of 1. Subtracting the former from the latter gives us the probability of scoring between 88 and 92.

An ant carries a piece of leaf home that is 1.25 x 10-2 grams and his partner carries home a piece of leaf that is 2.3 x 10-3 grams. What is the combined weight of their pieces of leaf?
the combined weight of the two pieces of leaf is 1.47 x 10⁻²grams.
HOW TO FIND WEIGHT ?
To find the combined weight of the two pieces of leaf, we simply need to add the weights of the individual pieces of leaf. We are given that one piece of leaf weighs 1.25 x 10⁻² grams and the other piece of leaf weighs 2.3 x 10⁻³ grams.
Adding these two weights, we get:
1.25 x 10⁻²grams + 2.3 x 10⁻³ grams = 1.47 x 10⁻² grams
Therefore, the combined weight of the two pieces of leaf is 1.47 x 10⁻²grams.
It's important to note that when working with scientific notation, we need to pay attention to the exponents and perform the operations according to the rules of exponents. In this case, we add the numbers in front of the exponent (1.25 and 2.3) and keep the exponent (10⁻²) the same.
It's also worth mentioning that this problem involves very small weights, as the values are expressed in grams using scientific notation. This is a common approach when dealing with very large or very small values in scientific contexts, as it allows us to easily express and compare values using a standardized format

The tank is filled in gallons per second at 0.158 gal/s, in cubic meters per second is 0.000600 m³/s, and the time interval required to fill a 1.00 m³ volume at the same rate is approximately 14.72 hours.
A. To calculate the rate at which the tank is filled in gallons per second, we can use the given information that it takes 5.25 minutes to fill a 50.0 gal gasoline tank. First, we convert the time from minutes to seconds by multiplying 5.25 by 60, which gives us 315 seconds. Then, we divide the volume of the tank (50.0 gals) by the time in seconds (315 s) to obtain the rate of filling in gallons per second, which is approximately 0.158 gal/s.
B. To calculate the rate at which the tank is filled in cubic meters per second, we need to convert the volume from gallons to cubic meters. One gallon is equal to 0.00378541 cubic meters. Thus, we multiply the rate in gallons per second (0.158 gal/s) by the conversion factor to obtain the speed in cubic meters per second, which is approximately 0.000600 m³/s.
C. To determine the time interval required to fill a 1.00 m³ volume at the same rate, we can set up a proportion using the rate in cubic meters per second (0.000600 m³/s). We can cross-multiply and solve for the time interval, which is approximately 14.72 hours.
In conclusion, the tank is filled at a rate of 0.158 gal/s, which is equivalent to 0.000600 m³/s. It would take approximately 14.72 hours to fill a 1.00 m³ volume at the same rate.

Kirby is trying to hypnotize Chrissy by swinging a pendulum at an angle of 80°.the length of chain attached is 10 inches long. What is the total are length AB that the pendulum travels
The total arc length AB that the pendulum travels is approximately 13.96 inches.
To find the total arc length traveled by the pendulum, we can use the formula for the arc length of a pendulum given by:
Arc length (s) = θ × r
where θ is the angle in radians and r is the length of the pendulum.
However, in this case, we are given the angle in degrees, so we need to convert it to radians. The formula for converting degrees to radians is:
θ (in radians) = (π/180) × θ (in degrees)
Given that the angle is 80°, we can convert it to radians as follows:
θ (in radians) = (π/180) × 80° = (4π/9) radians
Now, we can calculate the arc length:
Arc length (s) = (4π/9) radians × 10 inches
The total arc length traveled by the pendulum is therefore:
Arc length (s) = (40π/9) inches
To approximate the answer, we can use the value of π as approximately 3.14:
Arc length (s) ≈ (40 × 3.14/9) inches
Arc length (s) ≈ 13.96 inches
Therefore, the total arc length AB that the pendulum travels is approximately 13.96 inches.
Please note that this calculation assumes that the pendulum swings in a perfect arc without any friction or external factors affecting its motion. In reality, there may be slight variations due to factors such as air resistance or imperfections in the pendulum's motion.

At what points, if any, does f assume local maximum and minimum values? a). Find the critical points, if any. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The critical point(s) of f is/are x=____ (Simplify your answer. Use a comma to separate answers as needed.) B. The function f has no critical points. b. Determine where f is increasing and decreasing. Select the correct choice below and fill in the answer box complete your choice. (Type your answer in interval notation. Use a comma to separate answers as needed.) A. The function is increasing on the open interval(s) __and decreasing on the open interval(s) B. The function f is decreasing on the open interval(s) __, and never increasing. C. The function f is increasing on the open interval(s)___ and never decreasing.
a) The critical points of the function f are x = 8 and x = -9, which is option A. b) The function f is increasing on the open interval (-9, 8) and never decreasing i.e., option C and c) the function f may assume local maximum or minimum values at the endpoints x = -9 and x = 8.
a) To find the critical points of f, we need to find the values of x where the derivative f'(x) equals zero or is undefined. From the given derivative f'(x) = (x-8) ²(x+9), we can see that it is defined for all values of x. To find the critical points, we need to set f'(x) equal to zero and solve for x:
(x-8) ²(x+9) = 0
By setting each factor equal to zero, we can find the critical points:
x-8 = 0 or x+9 = 0
Solving these equations, we get:
x = 8 or x = -9
Therefore, the critical points of f are x = 8 and x = -9.
b) To determine where f is increasing or decreasing, we can examine the sign of the derivative f'(x) in different intervals. Considering the critical points x = 8 and x = -9, we can divide the number line into three intervals: (-∞, -9), (-9, 8), and (8, +∞).
For the interval (-∞, -9), we can choose a test point, for example, x = -10, and evaluate f'(-10). Since (-10-8)^2(-10+9) = (-18)^2(-1) = 324 < 0, f'(-10) is negative. Therefore, f is decreasing on the interval (-∞, -9).For the interval (-9, 8), we can choose a test point, for example, x = 0, and evaluate f'(0). Since (0-8)^2(0+9) = (-8)^2(9) = 576 > 0, f'(0) is positive. Therefore, f is increasing on the interval (-9, 8).For the interval (8, +∞), we can choose a test point, for example, x = 9, and evaluate f'(9). Since (9-8)^2(9+9) = (1)^2(18) = 18 > 0, f'(9) is positive. Therefore, f is increasing on the interval (8, +∞).c) Since f is increasing on the interval (-9, 8), it does not have any local maximum or minimum values within that interval. However, at the endpoints x = -9 and x = 8, f may assume local maximum or minimum values. To determine if these points correspond to local maximum or minimum, we need to examine the behavior of f around those points by evaluating f(x) itself.
Therefore, the answers to the questions are:
a) The critical points of f are x = 8 and x = -9. (Choice A).
b) The function is increasing on the open interval (-9, 8) and never decreasing. (Choice C).
c) The function f may assume local maximum or minimum values at x = -9 and x = 8, the endpoints of the interval.
