_
| 5, x < -3
f(x) | 2x² - 4, -3 ≤ x ≤ 4
| 1 - 6x , x > 4

When the x in f(x) is less than -3 than f(x) = 5
When the x in f(x) is greater than -3 but less than 4 then f(x) = 2x² - 4
When the x in f(x) is greater than 4 than f(x) = 1 - 6x

Before the search and collection of evidence, there must be _______.
A. Informed consent by the owner
B. A crime
C. A chain of custody
D. A search warrant
I’m stuck between D and B because law enforcement can conduct a search without a search warrant if there is consent by the owner. It is not C because that would be either during or after the collection of evidence.
Answers
Answer:
D) A search warrant
Step-by-step explanation:
A search warrant is required before the search and collection of evidence to ensure legal authorization and protection of individuals' rights against unreasonable searches and seizures.
Option B, "A crime", is incorrect because the presence of a crime is not a prerequisite for conducting a search and collection of evidence. There are various situations where searches and evidence collection may occur without a crime being involved, such as regulatory inspections, consented searches, or investigations into potential threats or risks.
By your logic when you say law enforcement can conduct a search without a search warrant if there is consent by the owner, that would mean option A would be right, but of course, it's not.
cultural anthropologists distinguish between ideal behavior (what people are expected to do) and real behavior (what people actually do)
Answers
Because cultural anthropologists are studying culture as it is and not as it would like it to be, anthropologists are concerned with actual behavior as opposed to ideal behavior.
A given group's social behavior, customs, achievements, and values are collectively referred to as its culture. It is the only thing that unites everyone in a society, regardless of country, social class, ethnicity, or religion. These things can be both material and immaterial, such as the importance of family or the customary dishes of a culture.
Anthropologists are unable to gather data with accuracy when people idealize their actions in front of them. Their entire study may be in jeopardy if they use false data.
Real culture is defined as the observed and quantified values, customs, and beliefs of a particular civilization. There may be a right and incorrect way to accomplish something in a culture, but exceptions are always possible. While some goals might be seen or expected, there is always room for the rules to be bent or even ignored in some circumstances because no civilization on Earth is genuinely an ideal society. As a result, there are lots of ambiguities.The ideals, customs, and viewpoints that a particular civilization professes to uphold or wants to do so are referred to as ideal culture in contrast to real culture. Instead of the reality that can be seen, it is the aim of a particular culture. Civilization is said to have an ideal culture when all of its members adhere to indisputable values and norms and act in ways that are generally seen as immoral. In an ideal culture, there are fewer exceptions and more clear-cut "rules." No society can, however, really live up to all of its values because people are fallible and frequently break the law.to know more about ' anthropology' try:

Find the required monthly payment to accumulate $32,000 in 10 years at an APR of 7.9% compounded monthly for an annuity.
Answers
Step-by-step explanation:
To calculate the required monthly payment to accumulate $32,000 in 10 years at an APR of 7.9% compounded monthly for an annuity, we can use the formula for the present value of an annuity due:
PV = PMT × ((1 - (1 + r/n)^(-n×t)) / (r/n)) × (1 + r/n)
where:
- PV is the present value of the annuity due ($32,000)
- PMT is the monthly payment we want to find
- r is the annual interest rate (7.9%)
- n is the number of times interest is compounded per year (12 for monthly compounding)
- t is the number of years (10)
PMT = PV / ((1 - (1 + r/n)^(-n×t)) / (r/n)) × (1 + r/n) = **$292.07**
Therefore, the required monthly payment to accumulate $32,000 in 10 years at an APR of 7.9% compounded monthly for an annuity is **$292.07**.

4(-4 + 9) + 1 ≥ -2(y + 7) - 8
Answers
Answer: Yes, Sierra is correct.
Step-By-Step Explanation:
The parenthesis on the left side is (-4+9). This can be combined because both terms are two constants. Constants are any terms in a algebraic equation or inequality whose value does not changed and is pre-defined. In this parenthesis, the answer would be 5.
The parenthesis on the right side contains one constant (7) and one variable (y). Since you can only combine like terms, y and 7 cannot be combined. Therefore, you cannot combine the right-side parenthesis.

It takes 3 gardeners 30 minutes to plant 18 trees. How many gardeners would it take to plant 45 trees in 45 minutes
Answers
Answer:
It will take 7.5 gardeners to plant 45 trees in 45 minutes
Step-by-step explanation:
It takes 3 gardeners 30 minutes to plant 18 trees.
Let's determine the rate of this 3 gardeners
Rate= 18 trees/30 minutes
Rate= 2/5 trees per minute
So 3 gardeners= 2/5 trees per minute
But then one Gardner= 2/(3*5) trees per minute
One Gardner=2/15 trees per minute
Let's determine the number of gardeners it will take to plant 45 trees in 45 minutes
One Gardner=2/15 trees per minute
X(22 /3)= 2/15*(22.5/3)
It will take 7.5 gardeners to plant 45 trees in 45 minutes

Part 1: The polynomial that represents the area of the hot tub = x² ft²; pool = (12x²-60x+75)ft² ; patio =.
Part 2: Cost of hot tub= $320; pool=$2541; patio = $104
How to determine the area of the hot tub, pool and patio?To determine the area of the hot tub, pool and patio is carried out using the formula for the area of rectangle. That is; Area of rectangle = length× width
For the hot tub:length = X ft
width = X ft
area = x² ft²
For the pool;length = (6x-15) ft
width = (2x-5) ft
area = 6x -15× 2x-5
= 12x²-30x-30x+75
= (12x²-60x+75)ft²
For patio:length= (10x-12) ft
width = 2 +(2x-5)
= (2x-3) ft²
The cost of hot tub, pool and patio when X= 8 would be as follows:
For hot tub:area = x²
X = 8
area = 64ft²
But 1 ft² = 5$
64 ft² = ?
cost of hot hub = 64×5 = $320
For pool;area = (12x²-60x+75)ft²
where X = 8
area = 12(8)²-60(8)+75
= 768-480+75
= 363ft²
But 1 ft² = $7
363ft² = ?
cost of the pool = 363×7 =$2541
For patio:Area = (2x-3) ft²
X = 8
area = 2(8)-3
= 13ft
But 1 ft² = $8
. 13ft² = ?
Cost of patio = 13×8 = $104

A Ferris wheel is 50 meters in diameter and boarded from a platform that is 4 meters above the ground. The six o'clock position on the Ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 2 minutes. How many minutes of the ride are spent higher than 38 meters above the ground?
answer in minutes.
Answers
The number of minutes spent higher than 38 meters above the ground on the Ferris wheel ride is approximately 1.0918 minutes.
To solve this problem, we need to determine the angular position of the Ferris wheel when it is 38 meters above the ground.
The Ferris wheel has a diameter of 50 meters, which means its radius is half of that, or 25 meters.
When the Ferris wheel is at its highest point, the radius and the height from the ground are aligned, forming a right triangle.
The height of this right triangle is the sum of the radius (25 meters) and the platform height (4 meters), which equals 29 meters.
To find the angle at which the Ferris wheel is 38 meters above the ground, we can use the inverse sine (arcsine) function.
The formula is:
θ = arcsin(h / r)
where θ is the angle in radians, h is the height above the ground (38 meters), and r is the radius of the Ferris wheel (25 meters).
θ = arcsin(38 / 29) ≈ 1.0918 radians
Now, we know the angle at which the Ferris wheel is 38 meters above the ground.
To calculate the time spent higher than 38 meters, we need to find the fraction of the total revolution that corresponds to this angle.
The Ferris wheel completes one full revolution in 2 minutes, which is equivalent to 2π radians.
Therefore, the fraction of the revolution corresponding to an angle of 1.0918 radians is:
Fraction = θ / (2π) ≈ 1.0918 / (2π)
Finally, we can calculate the time spent higher than 38 meters by multiplying the fraction of the revolution by the total time for one revolution:
Time = Fraction \(\times\) Total time per revolution = (1.0918 / (2π)) \(\times\) 2 minutes
Calculating this expression will give us the answer in minutes.

Evaluate log4 25 using common logarithms or natural logarithms. Round your answer to the nearest thousandth.
log4 25
Answers
Answer: 20 log (2)
Step-by-step explanation:
Answer: Logarithms are mathematical functions that are used to represent the relationship between two quantities that are related by a power law. For example, if we have an exponential equation like 2^x = 8, we can use logarithms to solve for x: log2 8 = x.
In general, logarithms are written in the form logb a, where b is the base of the logarithm and a is the number we want to take the logarithm of. There are several different bases in that logarithms can be written in, including the common logarithm (base 10) and the natural logarithm (base e).
To evaluate a logarithm, we need to use the logarithmic properties and the change of base formula. One important property of logarithms is that logb (xy) = logb x + logb y. Another property is that logb (x/y) = logb x - logb y.
The change of base formula is used when we need to evaluate a logarithm in a different base than the one given. The formula is:
logb a = logc a / logc b
where c is any base other than b or a. By using this formula, we can convert a logarithm from one base to another in order to evaluate it using a calculator.
In the case of log4 25, we can use the common logarithm (base 10) or the natural logarithm (base e) to evaluate the logarithm. Using the change of base formula with the common logarithm, we have:
log4 25 = log(25) / log(4)
Using a calculator, we find that log(25) ≈ 1.39794 and log(4) ≈ 0.60206, so:
log4 25 ≈ 1.39794 / 0.60206
Simplifying this expression, we get:
log4 25 ≈ 2.32193
Rounding to the nearest thousandth, we get:
log4 25 ≈ 2.322
So, the value of log4 25 to the nearest thousandth is 2.322.
