Answer:Perimeter is the limit of any given geometric figure. Circumference is just the name given to a circle’s perimeter, in other words, the circle’s limit, its edge.
The reason for this is because the perimeter is, by definition, the sum of the lenghth of every side of any given geometric figure. A circle has either no sides, or number of sides, so its perimeter has to be treated differently.
Remember that π (Pi) equals 3.141592 approximately. This is a constant, meaning that no matter what circle you are studying, Pi will always have the same value. It is the relation between the diameter and the lenght of its circumference. A circle with diameter xwill travel 3.141592x before it completes a revolution. This is where Pi comes from.
So the difference would be that a “normal” perimeter is only the sum of the sides. A circumference is the perimeter of a circle, given a diameter and the constant value of Pi, that derives from other properties of the circle, and not by its sides (remember a circle has either none or nnumber of sides).

The inverse relation of [tex]\( y = 3x + 12 \)[/tex] is [tex]\( x = \frac{y - 12}{3} \)[/tex].
To find the inverse of the relation [tex]\( y = 3x + 12 \)[/tex], we start by expressing it in terms of [tex]\( x \)[/tex] and [tex]\( y \)[/tex]:
[tex]\[ y = 3x + 12 \][/tex]
Next, solve for [tex]\( x \)[/tex]:
[tex]\[ y - 12 = 3x \][/tex]
[tex]\[ x = \frac{y - 12}{3} \][/tex]
Thus, the inverse relation is:
[tex]\[ x = \frac{y - 12}{3} \][/tex]
To verify, substitute [tex]\( x \)[/tex] with [tex]\( \frac{y - 12}{3} \)[/tex] back into the original equation:
[tex]\[ y = 3 \left( \frac{y - 12}{3} \right) + 12 \][/tex]
[tex]\[ y = y - 12 + 12 \][/tex]
[tex]\[ y = y \][/tex]
Therefore, the answer is [tex]\( x = \frac{y - 12}{3} \)[/tex].

Answer:
f(t)=15(1.0245)^12t
Step-by-step explanation:
It should be the first answer. Hope this helps:)
Final answer:
When modeling population growth, understanding functions like the logistic map and the Holling Type II functional response is crucial for accurate predictions of species dynamics.
Explanation:
Logistic Population Growth:
When modeling population growth with the logistic map, the most clear representation of monthly population growth is when the function includes a term that represents the rate of growth in relation to the existing population size. This is often seen as a term where the population in the next generation is a function of the population in the current generation multiplied by a constant, representing the fecundity of the species.
Holling Type II Functional Response:
In ecological situations, a commonly used model for predation is the Holling Type II functional response, where the rate of predation is described by a density-dependent function. This function accounts for increasing predation with higher prey density up to a saturation point, reflecting a more realistic portrayal of predator-prey dynamics.
Equilibrium and Growth Dynamics:
Equilibrium in population growth models can be explored using deterministic equations to find expectations, such as exponential growth when the birth rate exceeds the death rate. Understanding growth dynamics entails considering factors like carrying capacity, fecundity, and density-dependent functions to model population behaviors accurately.

O
C. $226.54
D. $236.89
Based on the cost of the car and the interest rate as well as the period, Jaclyn's monthly payment would be A. $298.81.
What would Jaclyn's monthly payment be?First find the amount she financed:
= Cost of car - down payment
= 11,000 - 1,000
= $10,000
Then find the monthly interest and number of periods:
= 4.8%/12 = 3 years x 12
= 0.4% = 36 months
Monthly payment would be:
Amount financed = Amount x ( 1 - (1 + rate)^-number of periods) / rate
10,000 = A x ( 1 - (1 + 0.4%)⁻³⁶) / 0.4%
10,000 = A x 33.4658758899
Amount = 10,000 / 33.4658758899
= $298.81

A spinner with 8 equal sections was spun 140 times. What is a reasonable prediction for the number of times the spinner will land on an even number? Show every step of your work
Answer:
If the spinner is spun 140 times then a reasonable prediction for the number of times the spinner will land on an even number = 0.5 [tex]\times[/tex] 140 = 70 times.
Step-by-step explanation:
The sections in the spinner are marked 1, 2, 3, 4, 5, 6, 7, 8
The even sections are 2, 4, 6, 8
There are 4 even sections and 4 odd sections among a total of eight sections.
Therefore the probability of the spinner landing on an even section is 1 / 2 or 0.5.
If the spinner is spun 140 times then a reasonable prediction for the number of times the spinner will land on an even number = 0.5 [tex]\times[/tex] 140 = 70 times.
Assuming that p equals .60 and the sample size is 1,000, what is the probability of observing a sample proportion that is at least .64?
Answer:
Therefore the probability of observing a sample proportion that is at least 0.64 = P(Z ≥ 2.58) = 1 - P(Z < 2.58) = 1 - 0.9951 = 0.0049
Step-by-step explanation:
It is given that p = 0.6
This is also the mean of the sample
Therefore q = 1 - p = 1 - 0.6 = 0.4
The sample size, n = 1000
Therefore standard deviation of the sample = [tex]\sqrt{\frac{p\times q}{n} } = \sqrt{\frac{0.6\times 0.4}{1000} } = \sqrt{\frac{0.24}{1000} } = 0.0155[/tex]
Z value for the sample proportion that is at least 0.64 [tex]= \frac{0.64 - 0.6}{0.0155} = 2.58[/tex]
Therefore the probability of observing a sample proportion that is at least 0.64 = P(Z ≥ 2.58) = 1 - P(Z < 2.58) = 1 - 0.9951 = 0.0049
Final answer:
To find the probability of observing a sample proportion of at least .64 with a population proportion of .60 and a sample size of 1,000, we calculate the standard error, find the Z-score, and then use this score to determine the probability from the standard normal distribution.
Explanation:
The question asks for the probability of observing a sample proportion of at least .64, given a population proportion (p) of .60 and a sample size of 1,000. To solve this problem, we use the normal distribution model for proportions because the sample size is large enough.
First, we calculate the standard error (SE) of the sampling distribution using the formula SE = [tex]\sqrt{[(p(1-p))/n],[/tex]where p is the population proportion and n is the sample size.
In this case, SE = sqrt[(0.6*0.4)/1000]. Next, we find the Z-score, which tells us how many standard deviations the sample proportion (.64) is away from the population proportion (.60), using the formula Z = (P' - p)/SE, where P' is the sample proportion. Finally, we use the Z-score to find the probability from the standard normal distribution table.

If gas costs $4 per gallon, how much will gas cost Sally per day just to get to and from Job A per day? per week? per year?
To find the cost of gas for Sally's commute, you would multiply the number of gallons she uses daily by the cost per gallon. Assuming a daily use of one gallon at $4 per gallon, Sally would spend $4 per day, $20 per week (5-day workweek), and $1,040 per year (52 workweeks). This does not account for variable factors such as days off or gas price changes.
Explanation:The student is asking about the cost of gasoline for commuting to and from a job. Since we do not have the exact distance Sally travels or the efficiency of her vehicle, we cannot compute the exact cost per day, week, or year. However, if we assume Sally uses one gallon of gas per day at a cost of $4 per gallon, here's how you calculate the costs:
Per day: Sally would spend $4 each day on gas.Per week: Assuming she works 5 days a week, Sally would spend 5 days x $4/day = $20 per week on gas.Per year: If Sally works 52 weeks a year, she would spend 52 weeks x $20/week = $1,040 per year on gas.These calculations are based on the premise of daily one-gallon gas usage and do not take into account vacations, days off, or possible fluctuations in gas prices.
Land in a development is selling for $60,000 per acre. If Jack purchase 1 ¾ acres, how much will he pay?
Answer:
The total cost is calculated to be $105,000.
Step-by-step explanation:
Here,
The cost of per acre land= $60,000
Jack is willing to purchase= 1 ¾acres = [tex]\frac{4*1+3}{4} =\frac{7}{4}=1.75[/tex] acres
Then,
By unitary method,
The cost of one acre land is $60,000 .
The cost of 1.75 acres is = $[tex]1.75*60,000[/tex]
The total cost of land is =$105,000.
So, Jack has to pay $105,000 to purchase 1.75 acres of land.
To find the total cost of 1 ¾ acres of land purchased at $60,000 per acre, multiply the price by the number of acres. Jack will pay $105,000 for the land.
Jack purchased 1 ¾ acres of land at $60,000 per acre. To calculate the total cost, multiply the price per acre by the total number of acres:
Total Cost = Price per acre x Number of acres
Total Cost = $60,000 x 1.75 = $105,000

What is Polygon?In geometry, the definition of a polygon is given as a closed two-dimensional figure with three or more straight lines. The Greek word "Polygon" consists of Poly meaning "many" and gon meaning "angle". We see many different polygons around us. For example, the shape of a honeycomb is a hexagon. Each polygon is different in structure, they are categorized based on the number of sides and their properties. Thus, all polygons are closed plane shapes.
Identification and Naming of PolygonsIt is a closed shape, that is, there is no end that is left open in the shape. It ends and begins at the same point.It is a plane shape, that is, the shape is made of line segments or straight lines.It is a two-dimensional figure, that is, it has only two dimensions length and width. There is no depth or height to it.The shape must have three or more sides.The angles in the polygon may or may not be the same.The length of the sides of a polygon may or may not be the same.Given:
angle measures: 80°, 100°, 80°, 100°
As, the sum of angles is 360
= 80+ 80 +100 +100
= 160 +200= 360
Also, pair opposite angles are equal.
Hence, the given polygon is rhombus.

what is 5/5/8 divided by 1/2/9 in simplest form
The division of 5/5/8 by 1/2/9 in simplest form is 405/88 after converting the mixed numbers to improper fractions, then multiplying by the reciprocal, and simplifying.
Explanation:To find the simplest form of the division of two mixed numbers, first, both mixed numbers must be converted to improper fractions. Dividing by a fraction is the same as multiplying by its reciprocal. So, when dividing 5/5/8 by 1/2/9, we first turn these into improper fractions.
5/5/8 becomes 45/8 (since 5*8+5=45) and 1/2/9 becomes 11/9 (since 1*9+2=11). Now the problem is 45/8 divided by 11/9. To divide these fractions, we multiply by the reciprocal: 45/8 * 9/11 = (45*9)/(8*11) = 405/88.
To simplify 405/88, we find the Greatest Common Divisor (GCD) of the numerator and the denominator, which is 1 in this case, so the fraction is already in its simplest form, which is 405/88.
To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. The reciprocal of 1/2/9 is 9/2/1. So, the expression becomes 5/5/8 multiplied by 9/2/1. To multiply fractions, we multiply the numerators together and the denominators together. So, (5 x 9) / (5 x 2) x 8 / 1 = 45/10 x 8/1 = 360/10 = 36.
25 multiplied by 3 algebraic expression
Answer:
25*3 or 25(3)
Step-by-step explanation:
Understanding arithmetic operations, like multiplication, and the order of operations, is essential in algebra. Parentheses dictate the order, as seen in '2 + (3 x 5)', resulting in 17. For algebraic manipulation, this understanding helps when working with variables and complex expressions like cubing exponentials or solving simultaneous equations.
Explanation:When faced with the phrase '25 multiplied by 3 algebraic expression', we might interpret this as the task of multiplying an algebraic expression by 25. Considering the examples provided, the manipulation of parentheses greatly influences the outcome of mathematical expressions.
The expression 2 + (3 x 5) includes parentheses, which indicate that multiplication should occur before addition, following the order of operations (PEMDAS/BODMAS). Here, the product of 3 and 5 is 15, and adding 2 results in 17.
However, if we were to apply the principle of algebraic multiplication to an unknown variable, say 'x', the expression would be 25x. If 'x' was the expression (2 + (3 x 5)), then 25x would be 25 times 17, or 425, after applying the order of operations within the parentheses.
Applying this method to simultaneous equations or Cubing of Exponentials, we can see the importance of understanding the principles of algebra and arithmetic operations.
When cubing exponentials, for example, you multiply the exponent by 3. This concept is crucial for solving more complex algebraic problems like those involving unknowns and linear equations.

5.5 lbs. =___ oz.
Answer: 80 ounces
Step-by-step explanation: lbs is the abbreviation for pounds and oz is the abbreviation for ounces.
To convert 5.5 pounds into ounces, first find the conversion factor for pounds and ounces which is shown below.
16 ounces = 1 pound
Next, notice that we're going from a larger unit, pounds, to a smaller unit, ounces. When we go from a larger unit to a smaller unit we multiply.
So here, we multiply 5.5 pounds times the conversion factor, 16 to get 88 ounces. This means that 5.5 pounds is equal to 88 ounces.
5.5 lbs is equal to 88 oz because 1 pound is equal to 16 ounces.
To convert pounds (lbs) to ounces (oz), you need to know that 1 pound is equal to 16 ounces.
1 pound=16 ounces.
Now we have to find out how many ounces are in 5.5 pounds.
To find this we have to multiply 5.5 by 16.
5.5 lbs×16 oz/lb
