Both have a domain of [tex][0, \infty)[/tex] which in other words, is the set of nonnegative real numbers. I recommend using a graphing calculator to verify both of these functions have the same domain.
The reason for this is because we need to avoid negative numbers under the square root. So it leads us to [tex]\text{x} \ge 0[/tex]

a quadratic equation can be written in vertex form or in standard form sometimes one form is more beneficial than the other Identify which form would be more helpful if you needed to do each task listed below and explain why. A .factor the equation. B graph the parabola.C identify the vertex minimum or maximum of the parabola D and solve the equation using the quadratic formula
Answers
a. In order to factor the equation, the vertex form needs to be expanded to the standard form first, to obtain the factors of the equation
b. The parabola is easily graphed with the information on the vertex given in the vertex form of the quadratic equation
c. The vertex, minimum or maximum of the parabola are easily obtained in the vertex form of the quadratic equation
d. The quadratic formula is defined based on the standard form of the quadratic equation
Answer:
[tex]\huge{\boxed{\text{A) Standard form}}}\\\huge{\boxed{\text{B) Vertex Form}}}\\\huge{\boxed{\text{C) Vertex Form}}}\\\huge{\boxed{\text{D) Standard Form}}}\\[/tex]
Step-by-step explanation:
Vertex form is represented as: [tex]f(x) = a(x-h)^2+k[/tex], where the vertex of the parabola is (h, k).
Standard form is represented as [tex]f(x) = ax^2+bx+c[/tex], where a, b, and c are constants.
A) When factoring an equation, the sum of the roots is equal to b and the sum of the roots is equal to c, meaning standard form is the beneficial.
B) When graphing a parabola, vertex form is extremely beneficial, as it provides the vertex of the parabola, and the direction in which it opens. If "a" is positive, the vertex opens upward, while when "a" is negative, the vertex opens downward. As such, graphing is greatly eased with this information.
C) As is evident from the name, vertex form is the best for identifying the vertex of a parabola, as it is explicitly shown via the constants h and k.
D) The quadratic formula directly uses the constants a, b, and c, so working in standard form is more beneficial, as it removes the effort of solving for each constant.

You are designing a rectangular poster to contain 48 in^2 of printing with a 3-in margin at the top and bottom and a 1-in margin at each side. What overall dimensions will minimize the amount of paper used?
Answers
To minimize the amount of paper used to create a rectangular poster with a given amount of printing and specific margins, you can use the formula for the area of a rectangle to determine the dimensions that will minimize the area of the poster.
In this case, the area of the poster must be at least 48 square inches to contain the printing, and the margins at the top and bottom must be 3 inches each, for a total of 6 inches. The margins at the sides must be 1 inch each, for a total of 2 inches. Therefore, the minimum area of the poster is 48 + 6 + 2 = 56 square inches.
To minimize the amount of paper used, we want to find the dimensions of the poster that will have the smallest possible area while still satisfying the constraints on the margins and the amount of printing. We can do this by using the formula for the area of a rectangle:
A = lw
where A is the area of the rectangle, l is the length, and w is the width.
In this case, we want to find the length and width that will minimize the area of the rectangle while still satisfying the constraints on the margins and the amount of printing. We can do this by setting the area of the rectangle equal to the minimum area we calculated above (56 square inches) and then solving for the length and width:
A = lw = 56
lw = 56
We can then use the constraints
There are technically ten configurations of poster measurements since the problem didn’t state if it was landscape or portrait in orientation. For example, l x w, using 6x8, changes to 8x14=112 sq in. since you added 2 in of length and 6 in of height; 8x6 changes to 10x12=120 sq in. The 4x12 and 12x4 variants yield 6x18 (108 sq in) and 14x10 (140 sq in). The 3x16 and 16x3 variants yield 5x22 (110) and 18x9 (162). Most likely the 2x24 and 1x48 print areas are not optimal, but yield 4x30=120, 26x8=208, 3x54=162, and 50x7=350, and make me wonder—what exactly is getting printed?! Context matters! At the end of all this, the 1x48 uses only 162 sq in of paper while maintaining the 48 sq in of printing space. That’s my answer. Go with the 1x48–>3x54=162 sq in. Good luck!
what is the equation of the line that passes through the point(-6,-7) and has a slope of 1/3
Answers
Answer:
The equation of the line that passes through the point (-6, -7) and has a slope of 1/3 is:
x - 3y + 15 = 0
Step-by-step explanation:
The equation of a line in slope-intercept form is given by y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis).
To find the equation of the line that passes through the point (-6, -7) and has a slope of 1/3, we can use the point-slope form of a line:
y - y1 = m(x - x1)
Where (x1, y1) is a point on the line and m is the slope of the line.
Plugging in the given values, we have:
y - (-7) = (1/3)(x - (-6))
Which simplifies to:
y + 7 = (1/3)x + 2
Multiplying both sides by 3, we have:
3y + 21 = x + 6
Subtracting 21 and 6 from both sides, we have:
3y - x - 15 = 0
Therefore, the equation of the line that passes through the point (-6, -7) and has a slope of 1/3 is:
x - 3y + 15 = 0

Rewrite the following equation in slope-intercept form. y − 9 = –10(x − 10)
Answers
Answer:
y = -10x + 109
Step-by-step explanation:
Given equation,
→ y - 9 = -10(x - 10)
The slope-intercept form is,

The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds 600 people. By selling tickets, the members would like to raise $3,300 every night to cover all expenses. Let d represent the number of adult tickets sold at $7.50. Let s represent the number of student tickets sold at $4.50 each. If all 600 seats are filled for a performance, how many of each type of ticket must have been sold for the members to raise exactly $3,300? At one performance there were two times as many student tickets sold as adult tickets. If there were 360 tickets sold at that performance, how much below the goal of $3,300 did ticket sales fall??
Answers
By using simultaneous linear equation, it can be calculated that-
200 adult tickets and 400 student tickets were sold
In another performance, ticket sale falls $1320 below the goal of $3300
What is simultaneous linear equation?
At first it is important to know about linear equation
Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.
A one degree equation is known as linear equation.
Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.
Here, a simultaneous linear equation needs to be solved
Here, d represents the number of adult tickets and s represents the number of student tickets
Their auditorium holds 600 people
d + s = 600 ..... (1)
Price of adult ticket = $7.50
Price of student ticket = $4.50
Total price = $(7.50d + 4.50s)
By the problem,
7.50d + 4.50s = 3300
5d + 3s = 2200 ..... (2)
Multiplying (1) by 3
3d + 3s = 1800.... (3)
Subtracting (3) from (2)
2d = 400
[tex]d = \frac{400}{2}[/tex]
d = 200
Putting the value of d in (1)
200 + s = 600
s = 600 - 200
s = 400
Now,
At one performance there were two times as many student tickets sold as adult tickets.
Total tickets sold = d + 2d = 3d
By the problem-
3d = 360
d = [tex]\frac{360}{3}[/tex]
d = 120
s = 2 [tex]\times[/tex] 120 = 240
Number of student ticket sold = 240
Number of adult ticket sold = 120
Total cost = 240 [tex]\times[/tex] 4.50 + 120 [tex]\times[/tex] 7.50
= $1980

Answers
The appropriate statistical conclusion is that there is sufficient evidence to conclude that the means are different.
How to interpret the test results?The null and the alternative hypothesis for this problem are given as follows:
Null hypothesis: means are equal.Alternative hypothesis: means are different.The p-value and the significance level for this problem are given as follows:
p-value: 0.034.Significance level: 0.05. (this is the standard when the significance level is not stated).As the p-value is less than the significance level, there is enough evidence to reject the null hypothesis, thus the appropriate statistical conclusion is that there is enough evidence to conclude that the means are different.
