• Interval notation in mathematics is a method to represent an interval of a number on the number line. In simpler words, interval notation is a way of writing subsets of the real number line .
• An interval comprises of the numbers lying between two specific given numbers. For example a set of numbers lying between 0 and 3 is an interval that contains 1,2.The way to represent interval notation is by using square bracket or round brackets, square brackets for both value included and round brackets for both value not included.
We are given that x is a real number which lies between -3 and -5 or any real number greater than or equal to 22
Firstly, x lies between -3 and -5
-5< x <-3
x = (-5,-3)
Secondly, x is greater than 22
x>=22
x = [22,00)

Ingrid walked her dog and washed her car. The time she spent walking her dog was one-half the time it took her to wash her car. It took Ingrid 23 minutes to walk the dog. How long did it take Ingrid to wash her car? Use the variable w to represent how long it took Ingrid to wash her car.
Answers
Let w be the time Ingrid took to wash her car.
We know that she spent half that time walking her dog, this means that:
\(\frac{1}{2}w\)is the time she spent walking her dog. We also know that she spent 23 minutes doing that, then we have the equation:
\(\frac{1}{2}w=23\)Solving for w we have:
\(\begin{gathered} \frac{1}{2}w=23 \\ w=2\cdot23 \\ w=46 \end{gathered}\)Therefore she spent 46 minutes whashing the car.

solve the system of two linear inequalities graphically.
y≤−5x−10
y>x+2
Answers
y≤−5x−10 and y>x+2 The shaded region satisfies both inequalities and represents the solution to the system of linear inequalities.
To graphically solve this system of linear inequalities, we can start by graphing each inequality on the same coordinate system:
First, let's graph the inequality y ≤ -5x - 10. We can start by graphing the line y = -5x - 10, which is the boundary line of the inequality. We can plot two points on this line, say (-2,0) and (0,-10), and draw a straight line passing through them.
Next, we need to determine which side of the line satisfies the inequality y ≤ -5x - 10. We can choose any point on one side of the line, say (0,0), and test it in the inequality. If y ≤ -5x - 10 is true for (0,0), then that side of the line satisfies the inequality. Otherwise, the other side satisfies the inequality. Testing (0,0), we have:
0 ≤ -5(0) - 10
0 ≤ -10
This is false, so the side of the line containing the origin does not satisfy the inequality. The other side of the line does.
Now, let's graph the inequality y > x + 2. We can start by graphing the line y = x + 2, which is the boundary line of the inequality. We can plot two points on this line, say (-2,0) and (0,2), and draw a straight line passing through them.
Next, we need to determine which side of the line satisfies the inequality y > x + 2. We can choose any point on one side of the line, say (0,0), and test it in the inequality. If y > x + 2 is true for (0,0), then that side of the line satisfies the inequality. Otherwise, the other side satisfies the inequality. Testing (0,0), we have:
0 > 0 + 2
This is false, so the side of the line containing the origin does not satisfy the inequality. The other side of the line does.
Now, we can shade the region that satisfies both inequalities. The shaded region is the region that is below the line y = -5x - 10 (including the line itself) and above the line y = x + 2 (excluding the line itself).
The shaded region is shown below:
Graph of y≤−5x−10 and y>x+2
The shaded region satisfies both inequalities and represents the solution to the system of linear inequalities.

2. The population of a town was 7,250 in 2014

increase from 2014 to 2015 to the nearest
tenth of a percent?
A) 1.5%
B) 1.6%
C) 1.7%
D) 1.8%
E) 2.0%
E
Answers
The percentage change of the population is P = 1.7 %
Given data ,
To calculate the percent increase from 2014 to 2015, we need to find the difference between the two population values, divide it by the initial value, and then multiply by 100 to get the percentage.
Population increase = 7,375 - 7,250 = 125
Percent increase = (Population increase / Initial population) * 100
Percent increase = (125 / 7,250) * 100 ≈ 1.7241
Rounding to the nearest tenth of a percent, the percent increase is approximately 1.7%.
Hence , the percentage change is P = 1.7 %

When pricing out a menu, we know it is important to use the Edible Portion Price. What would the effect on your profit margin be if we only used the As Purchased Price to determine our cost and selling price?
Answers
The effect on the profit margin if the as purchased price to determine the cost and selling price is that it will maximize the profit
What is edible portion cost?Your portion costs are the cost of a serving of an individual ingredient or recipe. For example, your ground beef portion cost on the hamburger is the total cost of ground beef per burger. Another example is if you sell smoked brisket by the pound, your portion cost is the cost per pound of brisket.
This is the process of calculating edible portion cost;
1.Calculate what it costs for you to make a dish
2.Find out Price of Dish to Customer.
3.Divide Total Cost of Dish Per Serving by Price of Dish to Customer.

The value of the definite integral is -607/6.
What is integral ?
In calculus, an integral is a mathematical concept that represents the area between a curve and the x-axis over a given interval, as well as the accumulation of a function over an interval. The integral is a fundamental tool in calculus and is used to solve a wide variety of problems in mathematics, science, and engineering.
There are two types of integrals: indefinite integrals and definite integrals. An indefinite integral is the antiderivative of a function, which is a function whose derivative is equal to the original function. It is represented by the symbol ∫ f(x) dx, where f(x) is the integrand and dx represents the infinitesimal change in the independent variable x. The indefinite integral is a family of functions that differ only by a constant of integration.
According to the question:
We can use the definite integral to find the area between the given function and the x-axis over the interval [-5,-2]. To evaluate the definite integral, we first need to find the antiderivative of the integrand:
\(∫(-x^3 - 11x^2 - 35x - 27) dx = (-1/4)x^4 - (11/3)x^3 - (35/2)x^2 - 27x + C\)
where C is the constant of integration.
To evaluate the definite integral over the interval [-5,-2], we substitute the upper and lower limits of integration into the antiderivative and take the difference:
\(∫(-x^3 - 11x^2 - 35x - 27) dx from -5 to -2\)
=\([(-1/4)(-2)^4 - (11/3)(-2)^3 - (35/2)(-2)^2 - 27(-2)] - [(-1/4)(-5)^4 - (11/3)(-5)^3 - (35/2)(-5)^2 - 27(-5)]\)
= [4 - (88/3) - 70 + 54] - [625 - (275/3) - (875/2) + 135]
= -607/6
Therefore, the value of the definite integral is -607/6.

Answers
The average number of hours that adults spend working each day is 8 hours and Ryan is correct because he got the average of 8 right.
We know that,
The sample mean is a statistic that is computed by taking the arithmetic mean of the values of a variable in a sample. If the sample is taken from probability distributions with a shared expected value, the sample mean is an estimator of that value.
The mean is gotten from the formula;
x' = ∑x/n
Number of hours of work per day are; 6, 7, 8, 9 and 10
Thus; sum up all of it
∑x = 6 + 7 + 8 + 9 + 10
∑x = 40
Mean is; x' = 40/5
x' = 8
Since Ryan concluded that the average is 8 hours,
Therefore,
We can say that Ryan is correct.

Answers
We treat A as a function of the variables and b and equating its partial derivatives with respect to a and b to 0. This gives {-64/(a^2)}+b=0, which means b=64/a^2. Since A(a,b) is symmetric in a and b, partial differentiation with respect to b gives a=64/b^2, ==>a=64[(a^2)/64}^2 =(a^4)/64. From this we get a=0 or a^3=64, which has the only real solution a=4. From the above relations or by symmetry, we get b=0 or b=4. For a=0 or b=0, the value of V is 0 and so are inadmissible. For a=4=b, we get h=32/ab =32/16 = 2.
Therefore the box has length and breadth as 4 ft each and a height of 2 ft.
