Answer:
C. -1 < x < 2.
Step-by-step explanation:
Change to vertex form to find the axis of symmetry:
x^2 − x −1
= (x - 0.5)^2 - 0.25 - 1
= (x - 0.5)^2 - 1.25.
Thus the graph is symmetrical about x = 0.5.
So the interval must be equal lengths either side of x = 0.5.
That would be -1 < x < 2.
A local school board is conducting a study of the growth in student enrollment in its schools. This growth can be modeled by the function f(t)=5230(1.015)t
, where t represents the number of years since the study began.
Which function can be used to represent the student enrollment m months after the study began?
Responses
f(m)=5230(1.015×12)m
f(m)=5230(1.015)12m
f(m)=5230(1.015)m12
f(m)=5230(1.01512)m
The correct answer is f(m)=5230(1.015)m12.
What is function?A function is a self-contained block of code that takes inputs, performs specific operations on those inputs, and produces an output. It is a subprogram that performs a specific task, and helps to break down larger programs into smaller, more manageable pieces. Functions are also reusable, meaning that once a function is written, it can be used over and over again in different places in the program.
This function can be used to represent the student enrollment m months after the study began, as it takes into consideration the number of years (t) represented by the number of months (m) and incorporates it into the equation. The equation multiplies the number of months (m) by 12 to convert it into the number of years (t) used in the original equation, f(t)=5230(1.015)t. This ensures that the correct student enrollment is calculated based on the number of months since the study began.

The translation that occurred to the segment is: B. The segment was shifted to the right four units and up five units.
What is Translation?Translation is a transformation in which an object is moved without being rotated, resized or distorted. It involves sliding the object a certain distance in a certain direction, while maintaining its shape and size. The resulting image of the object is congruent to the original object, meaning that they have the same size and shape.
To find the translation that occurred to the segment, we need to calculate the distance between point A and its image A' and the direction in which the translation occurred.
The distance between A and A' is given by:
√((7-3)² + (2-(-3))²) = √(16 + 25) = √(41)
So the segment was translated by a distance of √(41).
To find the direction of the translation, we can subtract the coordinates of A from the coordinates of A':
(A'x - Ax, A'y - Ay) = (7-3, 2-(-3)) = (4, 5)
So the segment was shifted to the right four units and up five units.
Therefore, the correct answer is B. The segment was shifted to the right four units and up five units.

The seventh grade wants to break last year’s record of 78 coats collected for the annual clothing drive. They have already collected 13 coats.
Which inequality represents the number of coats, c, that the seventh grade must still collect?
Answer:
[tex]c+13 > 78[/tex]
Step-by-step explanation:

Russell has been training for the Emerald Valley Race. The first week he trained, he ran 5 days and took the same two routes each day. He ran 2 miles around the football field before school and ran a longer route through his neighborhood after school. By the end of the week, Russell had run a total of 30 miles.
Using the arithmetic operations it is obtained that Russell ran 4 miles through his neighborhood every day after school.
To solve this problem, we can use the following equation -
total distance = distance per day x number of days
We know that Russell ran 2 miles around the football field before school every day.
Using multiplication,
Therefore, his total distance for the week from running around the football field is -
2 miles/day × 5 days = 10 miles
We also know that Russell ran a longer route through his neighborhood after school every day.
Let's call the distance of this route "x" miles.
Russell ran this route 5 times during the week, so his total distance from running through his neighborhood is -
Use multiplication,
x miles/day × 5 days = 5x miles
Finally, we know that Russell's total distance for the week was 30 miles. We can set up the equation -
Use addition,
10 miles + 5x miles = 30 miles
Simplifying, we get -
5x miles = 20 miles
x = 4 miles
Therefore, the distance value is obtained as 4 miles.

2 glasses of milk and 3 snack bars have a total of 73 carbohydrates (carbs), and 4 glasses of milk and 2 snack bars have a total of 86 carb how many carbs are in 1 snack bar
In the given situation, one snack bar has 14 carbohydrates.
How to calculate the no. carbs in one snack bar?Let's denote the number of carbs in one snack bar as "x".
From the given information, we can set up a system of two equations:
2x + 3y = 73 (where y is the number of carbs in one glass of milk)
4x + 2y = 86
We can then solve for x by using elimination or substitution.
Using elimination, we can multiply the first equation by 2 and subtract it from the second equation:
4x + 2y = 86
(4x + 6y = 146) (2 times the first equation)
-4y = -60
Dividing both sides by -4, we get:
y = 15
Substituting this value of y into the first equation, we can solve for x:
2x + 3y = 73
2x + 3(15) = 73
2x + 45 = 73
2x = 28
x = 14
Therefore, there are 14 carbs in one snack bar.
Step-by-step explanation:
Let's start by defining some variables to represent the unknowns in the problem:
Let x be the number of carbohydrates in one snack bar.
Now, we can use the given information to set up a system of equations:
2x + 3y = 73 (where y is the number of carbohydrates in one glass of milk)
2y + 4x = 86
We have two equations and two unknowns, so we can solve for x and y using any method we prefer. Here, we will use the substitution method:
Rearrange the first equation to solve for y: y = (73 - 2x)/3
Substitute this expression for y in the second equation: 2((73 - 2x)/3) + 4x = 86
Simplify: (146 - 4x)/3 + 4x = 86
Multiply both sides by 3 to eliminate the fraction: 146 - 4x + 12x = 258
Simplify: 8x = 112
Solve for x: x = 14
Therefore, one snack bar has 14 carbohydrates.

DIVIDING INTEGERS. Sarah and Anna both ran five laps of a race. When Anna finished, Sarah was 15 meters behind Anna suppose Sarah fell behind the same number of meters during each lap write an integer that describes how far is Sarah fell behind each lap
Sarah fell behind 3 meters each lap.
What is Total distance?
Whole distance refers to the actual travel distance between the origin and destination locations of the item.
If Sarah was 15 meters behind Anna when Anna finished the race, and they both ran the same distance, we can divide the total distance by the number of laps they ran to find the distance they ran per lap:
Total distance = 5 laps
Distance per lap = total distance / number of laps = 5 laps / 1 = 5
So Sarah and Anna each ran 5 meters per lap. If Sarah fell behind the same number of meters during each lap, we can use a negative integer to describe the distance she fell behind each lap. The distance she fell behind each lap is:
-3 meters (since 3 meters + 3 meters + 3 meters + 3 meters + 3 meters = 15 meters, which is the distance by which she was behind when Anna finished the race).
Therefore, Sarah fell behind 3 meters each lap.

As a result, after five years, the business makes $102.10 per hour of work performed by men.
What are a company's earnings?The gains that a company makes are its earnings. They are obtained by deducting revenue from cost of products sold, running costs, and taxes. The creation and ongoing running of a company are primarily motivated by the desire to generate profits. Dividend payments to stockholders can then be made with the earnings.
If the factory earned $80 per man-hour of labor when it opened, and each year earns an additional 5% per man-hour, we can calculate the earnings for any given year using the formula:
E = $80 × (1 + r)ⁿ
where E is the earnings per man-hour, r is the annual rate of increase (5% = 0.05), and n is the number of years since the factory opened.
For example, if we want to find the earnings per man-hour after 3 years, we would plug in n=3:
E = $80 × (1 + 0.05)³
E = $80 × 1.157625
E = $92.61
Therefore, after 3 years, the factory earns $92.61 per man-hour of labor.
Similarly, if we want to find the earnings per man-hour after 5 years, we would plug in n=5:
E = $80 × (1 + 0.05)⁵
E = $80 × 1.276282
E = $102.10

Describe Measurements?Measurement is the process of assigning a numerical value to a physical quantity, such as length, weight, temperature, or time. Measurements are used to quantify and compare different aspects of the world around us, and they play a crucial role in many areas of science, engineering, and everyday life.
Measurements can be made using a variety of tools and techniques, ranging from simple rulers and scales to sophisticated scientific instruments. The accuracy and precision of a measurement depend on many factors, including the quality of the measuring instrument, the skill of the person making the measurement, and the conditions under which the measurement is taken.
In order for measurements to be meaningful and useful, they must be expressed in units that are well-defined and universally accepted. The International System of Units (SI) is the most widely used system of units in the world, and it is based on seven fundamental units of measurement, including the meter for length, the kilogram for mass, the second for time, and the kelvin for temperature.

What is meant by compound interest?Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit. The interest charged on a loan or deposit is known as compound interest. That is the idea that we employ the most frequently on a daily basis. The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest.
Given,
The principal amount P = $30,000
The time period t = 40 years
The rate of interest r = 10%
The number of times compounded in a year n = 1
The compound interest formula can be used to calculate the amount at the end of 40 years.
[tex]A = P(1 + \frac{r}{n})^{nt} = 30000(1 + \frac{0.1}{1})^{1*40}[/tex] = $1,357,777.67

What is polynomial?A polynomial is a mathematical expression that consists of variables, coefficients, and exponents, combined using the operations of addition, subtraction, and multiplication. Polynomials are widely used in mathematics and other fields to model a wide range of phenomena and processes. In a polynomial, the variables are usually represented by letters such as x, y, or z, while the coefficients are numbers that multiply the variables. The exponents indicate the power to which each variable is raised.
Here,
To determine which trinomials are prime, we need to factor each trinomial and check if it can be factored further into linear factors with integer coefficients. If a trinomial can be factored further, then it is not prime. On the other hand, if a trinomial cannot be factored further, then it is prime.
Let's factor each trinomial and see which ones are prime:
x² + 11x + 18
This trinomial can be factored into (x + 2)(x + 9), so it is not prime.
x² + 11x + 18
This trinomial can be factored into (x + 2)(x + 9), so it is not prime.
x² – 3x – 2
This trinomial can be factored into (x – 2)(x + 1), so it is not prime.
x² – 3x – 2
This trinomial can be factored into (x – 2)(x + 1), so it is not prime.

(a) n= (Round up to the nearest integer.)A researcher wishes to estimate the proportion of adults who have high-speed Internet access. What size sample should be obtained if she wishes the estimate to be within 0.03 with 99% confidence if (a) she uses a previous estimate of 0.52? (b) she does not use any prior estimates? (A)n=
The required sample sizes are given as follows:
a) Previous estimate of 0.52: n = 1839.
b) No previous estimate: n = 1842.
What is a confidence interval of proportions?A confidence interval of proportions has the bounds given by the rule presented as follows:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which the variables used to calculated these bounds are listed as follows:
[tex]\pi[/tex] is the sample proportion, which is also the estimate of the parameter.z is the critical value.n is the sample size.The confidence level is of 99%, hence the critical value z is the value of Z that has a p-value of 0.995, so the critical value is z = 2.575.
The margin of error is given as follows:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
For an estimate of 0.52, the parameters are given as follows:
[tex]M = 0.03, \pi = 0.52[/tex]
Hence the sample size is obtained as follows:
[tex]0.03 = 2.575\sqrt{\frac{0.52(0.48)}{n}}[/tex]
[tex]0.03\sqrt{n} = 2.575\sqrt{0.52 \times 0.48}[/tex]
[tex]\sqrt{n} = \frac{2.575\sqrt{0.52 \times 0.48}}{0.03}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{2.575\sqrt{0.52 \times 0.48}}{0.03}\right)^2[/tex]
n = 1839.
Without a previous estimate, the sample size is given as follows:
[tex]0.03 = 2.575\sqrt{\frac{0.5(0.4)}{n}}[/tex]
[tex]0.03\sqrt{n} = 2.575\sqrt{0.5 \times 0.5}[/tex]
[tex]\sqrt{n} = \frac{2.575\sqrt{0.5 \times 0.5}}{0.03}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{2.575\sqrt{0.52 \times 0.5}}{0.03}\right)^2[/tex]
n = 1842.

What is the value of x?
9 is the equivalent value of x from the given triangle.
The triangular bisector theoremThe angle bisector theorem is concerned with the proportions of the two segments that a line that bisects the opposite angle divides a triangle's side into.
Applying the rule to solve the given question, we will have:
3x-7/12 = 3x +3/18
Cross multiply
12(3x+3) = 18(3x-7)36x + 36 = 54x - 126
Collect the like terms
36x-54x = -126 - 36
-18x = -162
x = 162/18
x = 9
Hence the value of x from the given figure is 9.
