Answer:
Well some places are more expensive. This will effect the prices of utilities because some places have a higher expense of living because of the lack of certain materials or because of the desirable location. For example, although living in Hawaii was beautiful, it was extremely expensive for everyday items because most things needed to be shipped and because of constant tourism.
The factor for dependency of Utility Cost shown below.
What is Utility Cost?The cost of using utilities like power, water, waste disposal, heating, and sewage is known as a utilities expense. During the reporting period, the costs are incurred, computed, and accumulated for, or a payment is made.
Given:
Due to climate and fluctuating utility prices, location might affect your utility expenditures. The expense of heating would be higher in an extremely cold climate than in a warmer one.
Certain locations are more pricey. The cost of utilities will be impacted because some regions have a greater cost of living due to a shortage of specific materials or a desirable location.
For instance, even though Hawaii was a wonderful place to live, the cost of basic necessities was very high due to the frequent tourism and the fact that the majority of goods had to be shipped.

What is the average rate of change of the function f(x)=5(2)^x from x = 1 to x = 5? Enter your answer in the box.
Answer:
37.5
Step-by-step explanation:
The average rate of change is the amount over an interval the outputs change in a ratio to the input change. In a linear function, this is constant and called slope. In all other function, it is called the average rate of change because the rate of change varies over the interval. We use the same formula for the average rate of change as we do slope. First we need both the inout and output values of the function over the interval.
For x=1, [tex]f(1)=5(2^1)=5(2)=10[/tex].
For x=5, [tex]f(1)=5(2^5)=5(32)=160[/tex]
Slope:[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We substitute [tex]x_1=1\\y_1=10[/tex] and [tex]x_2=5\\y_2=160[/tex]

In Circle O, secants ADB and AEC are drawn from external point A such that points D, B, E, and C are on Circle O. If AD=8, AE=6, and EC is 12 more than BD, find the length of AC.
The problem can be solved using the power of a point theorem. First, let BD = x and EC = x + 12. Construct an equation: 8x = 6(x+12). Solving for x gives BD = 9 and EC = 21. The length of AC is then 35.
Explanation:This problem can be solved using the concept of power of a point theorem in circle geometry. The power of a point theorem states that for any point outside a circle, the product of the lengths of the two line segments obtained by drawing secants from that point to the circle are always equal.
To apply this theorem to this problem, we'll first denote BD as x. Because the problem states that EC is 12 more than BD, we can denote EC as x + 12.
Now, using the power of a point theorem, we can write the equation (AD)*(DB) = (AE)*(EC). Substituting in the given values and the values we denoted for DB and EC, we get (8)*(x) = (6)*(x+12).
Solving this equation gives x = 9. Therefore, the length of BD is 9, and the length of EC is 21. To find the length of AC, we add the lengths AE, EC, and AD, which gives us AC = 6 + 21 + 8 = 35.

To determine the number of different Hyundais available in black or blue, you multiply the number of dealerships (6) by the number of Hyundai models (8) and the number of relevant colors (2), resulting in 96 different cars.
The question asks how many different cars you can buy if you want a black or blue Hyundai, given certain constraints. There are six dealerships, two car companies, eight models, and four colors available. To answer this, we calculate the total combinations possible with the given choices: dealerships (6), car companies (2), models (8), and colors (4). Since we are only interested in Hyundai cars in black or blue, we eliminate other colors and car companies from the choice set. The calculation is as follows:
Number of dealerships: 6
Car companies: 1 (only Hyundai)
Car models: 8
Car colors: 2 (black or blue)
To find the total number of possible combinations, we multiply the number of each category's choices together:
6 (dealerships)
* 1 (Hyundai)
* 8 (models)
* 2 (colors)
= 96 different cars

A die is rolled. What is the probability of rolling a 5 or a number greater than 3?
Probability of rolling a 5: 1/6
Probability of rolling a number greater than 3: 3/6
The probability of rolling a 5 or a number greater than 3 on a six-sided die is calculated by summing the individual probabilities of rolling a 4, 5, or 6, which are each 1/6. Therefore, the total probability is 3/6 or 1/2, equating to a 50% chance.
To solve this, we need to identify the favorable outcomes and divide them by the total number of possible outcomes. A six-sided die has six possible outcomes: {1, 2, 3, 4, 5, 6}. The event of rolling a 5 or a number greater than 3 includes the outcomes {4, 5, 6}. Hence, there are three favorable outcomes for the desired event (rolling a 4, 5, or 6).
The probability of any single outcome is 1/6, as there are six sides to the die. Therefore, the probability of rolling a 5 or a number greater than 3 is calculated by adding the probabilities of rolling each of these numbers:
Probability of rolling a 4 = 1/6Probability of rolling a 5 = 1/6Probability of rolling a 6 = 1/6Adding these probabilities gives us 3/6 or 1/2, making the probability of rolling a 5 or a number greater than 3 being 50%.

There are 230 calories in 4 ounces of a type of ice cream how many calories are in 6 ounces of that type of ice cream
Answer: at this amount, there are 57.5 calories per ounce
therefore, there are 355 calories in 6 ounces of this ice cream
(since 57.5×6=355.0)
Answer:
345 calories
Step-by-step explanation:
Total Calories = 230 calories
Total amount = 4 ounces
TO find how many calories in 6 ounces of the ice cream
For this question we have to find out the number of calories in one ounce of an ice cream firs
as it is given to us that 230 calories in 4 ounces
so no of calories in one ounce = total calories / no of ounces
=230 / 4
=57.5 calories / ounce
Now we know that their are 57.5 calories in one ounce of the ice cream
We have to find no of calories in 6 ounces of ice cream
No of calories = 6 * 57.5
=345 calories
so amount of calories in 6 ounces are 345 calories

Felicia has $4.17 in change. After she takes out the quarters, she has $4.42 left. How many quarters did she take out
Final answer:
Felicia took out 1 quarter from her change. The difference in amount between before and after removing the quarters, which is $0.25, indicates that only one quarter was removed as each quarter is worth $0.25.
Explanation:
To determine how many quarters Felicia took out of her total change, we need to calculate the difference between the amount she had initially and the amount she had after removing the quarters.
Initially, Felicia had $4.17. After she removes the quarters, she is left with $4.42. The difference between these two amounts will tell us the total value of the quarters removed.
Subtract the smaller amount from the larger amount: $4.42 - $4.17 = $0.25.
Since each quarter is worth $0.25, we divide the total value of the quarters taken out by the value of one quarter to find the number of quarters.
$0.25 ÷ $0.25 per quarter = 1 quarter.
Therefore, Felicia took out 1 quarter.

The graph of a polynomial function of degree 5 has three x-intercepts, all with multiplicity 1. Describe the nature and number of all its zeros.
Answer: C
Step-by-step explanation:
Degree of 5 means there are 5 roots.
If 3 roots are real, then there are 2 remaining - which must be imaginary.
Answer:
The answer is C.
Step-by-step explanation:
Recall that as consequence of the Fundamental Theorem of Algebra, a polynomial of n-th degree has n complex roots (some roots, or all of them, can be real).
Now, as we have a polynomial of degree 5, it has 5 roots. From the statement we know that its graph has three intercepts with the X-axis, which is equivalent to the existence, at least, of three real roots. Moreover, we know that the multiplicity of each root is one. Then, we have exactly three real roots.
The above deduction means that there are other two roots, and those must be complex.
Suppose A and B represent two different school populations where A > B and A and B must be greater than 0. Which of the following expressions is the largest? Explain why. Show all work necessary. 2(A + B) (A + B)2 A2 + B2 A2 − B2
Answer:
The value for the expression [tex](A+B)^{2}[/tex] is the largest
Step-by-step explanation:
Since both A and B must be greater than 0 and A>B then we can assume the least possible values for B=1 and A=2.
So,
i) 2(A+B) = 2(2+1) = 2*3 = 6
ii) [tex](A+B)^{2}[/tex] = (A+B)*(A+B) = (2+1)*(2+1) = 3*3 = 9
iii) [tex]A^{2} + B^{2}[/tex] = [tex]2^{2} +1^{2}[/tex] = 4+1 = 5
iv) [tex]A^{2} - B^{2} = 2^{2} - 1^{2}[/tex] = 4-1 =3
Inspecting the answers of the above four expressions, we see that the value for the expression [tex](A+B)^{2}[/tex] is the largest.
Answer: (A+B)^2 is the largest because it equals 9 when A=2 and B=1 are plugged in and the rest are less than 9

The guards change over between 10:16 pm and 10:25 pm which means the hallway is clear during that time. How many minutes do you have exactly to cross the yard without being noticed?
Answer:
8 minutes.
Step-by-step explanation:
We have been given that the guards change over between 10:16 pm and 10:25 pm which means the hallway is clear during that time.
We can see that the very first minute to cross the hallway without being noticed will be after 10:16 pm as guards start change over at 10:16 pm.
The very last minute to cross the hallway without being noticed will be before 10:25 pm as guards end change over at 10:25 pm.
So let us count number of minutes between 10:16 pm to 10:25 pm without including 10:16 pm and 10:25 pm.
So these minutes will be: 10:17 pm, 10:18 pm, 10:19 pm, 10:20 pm, 10:21 pm, 10:22 pm, 10:23 pm, 10:24 pm.
Since given time interval includes 8 minutes, therefore, we have only 8 minutes to cross the yard without being noticed.
The person have only [tex]\boxed{{\mathbf{8 minutes}}}[/tex] to cross the yard without being noticed.
Further explanation:
It is given that the guards change over between [tex]10:16{\text{ pm}}[/tex] and [tex]10:25{\text{ pm}}[/tex] that means hallway is clear on that time.
The person can cross the halfway in the absence of the guard when the guards change over.
The person can cross the hallway after [tex]10:16{\text{ pm}}[/tex] without being noticed therefore, it is the very first minute to cross the hallway.
The person can cross the hallway before [tex]10:25{\text{ pm}}[/tex] without being noticed therefore, it is the very last minute to cross the hallway.
Now count the timings in which the person can cross hallway without being noticed.
[tex]\begin{aligned}10:17{\text{ pm,}}10:18{\text{ pm}},10:19{\text{ pm}},10:20{\text{ pm,}} \hfill \\10:21{\text{ pm, }}10:22{\text{ pm,}}10:23{\text{ pm, }}10:24{\text{ pm}} \hfill\\{\text{ }}\hfill\\\end{aligned}[/tex]
Therefore, it can seen from the above timings that the time interval is 8 minutes in which the person can cross hallway as the hallway is clear.
Thus, the person have only [tex]8{\text{ minutes}}[/tex] to cross the yard without being noticed.

Triangles △ABC and △DEF are similar. Find the lengths of the sides of △DEF, if AB=2 cm, BC=3 cm, CA=4 cm, DE=1.5 cm.
Answer:
DF=3.0cm, EF=3cm
Step-by-step explanation:
Given: ΔABC is similar to ΔDEF,
Therefore: [tex]\frac{AB}{DE} =\frac{AC}{DF}[/tex]
⇒[tex]\frac{2}{1.5}= \frac{4}{DF}[/tex]
⇒ DF=3.0cm
Now, by the similarity of triangles, we have Ef=3cm.
Answer:
The sides of △DEF are DE = 1.5cm, DF = 3cm, and EF= 2.25 cm.Step-by-step explanation:
We know that
[tex]\triangle ABC \sim \triangle DE\ F[/tex]
[tex]AB=2cm\\BC=3cm\\CA=4cm\\DE=1.5cm[/tex]
Remember that a similarity between two triangles represent a proportional relation between corresponding side. In this case, such proportions are
[tex]\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}[/tex]
So, we have to find sides DF and EF. Using given values, we have
[tex]\frac{AB}{DE}=\frac{BC}{EF}\\ \frac{2}{1.5}=\frac{3}{EF}\\ EF=\frac{3(1.5)}{2}=2.25[/tex]
Then,
[tex]\frac{AB}{DE}=\frac{AC}{DF}\\\frac{2}{1.5}=\frac{4}{DF}\\ \\DF=\frac{4(1.5)}{2}=3[/tex]
Therefore, the sides of △DEF are DE = 1.5cm, DF = 3cm, and EF= 2.25 cm.

The equation that models this trip is T = 36x + 60, where T represents the total cost for the group to take the trip and x equals the number of people going. What values are appropriate for the domain?
A) x = 40
B) x = 60
C) 0≤ x≤ 40
D) 0≤ x≤ 39
Given equation is:
[tex]T=36x+60[/tex]
Where T is the total cost; $36 is the entry fee per person and $60 is the one time bus parking fee.
As given, the bus holds up to 40 people, so let the total number of people be represented by 'x'
The bus holds up to 40 people so 'x' is either less than 40 or equal to 40.
Or this can be written as : [tex]x\leq 40[/tex]
Hence, the domain will lie between 0 and 40.
