Answer:

x² - 9x + 14 = (x - 2)(x - 7)

The correct answer is D.

Answer:

B - 8

Step-by-step explanation:

The answer is 8 because when determining the degree of any polynomial you find the sum of all the exponents that are attached to variables.

Since there's only one variable then you only have to take the number attached to the variable "x" which is 8.

Answer:

arc AB = 60°

Step-by-step explanation:

The diameter splits the circle into two semi circles.

in the semicircle above the diameter, you can do 180° - 120° = 60°

so arc AB = 60°

( I'm sorry; I'm not sure how to get the answer in terms of pi. )

Answer:

D

Step-by-step explanation:

The slope is the change in y-coordinates divided by the change in x-coordinates.

Here, the y-coordinates are -4 and -1, and the x-coordinates are -3 and 0, so:

slope = m = (-4 - (-1)) / (-3 - 0) = -3 / -3 = 1

The slope is thus 1, so the answer is D.

We can use the points (-3, -4) and (0, -1) to solve.

Slope formula: y2-y1/x2-x1

= -1-(-4)/0-(-3)

= 3/3

= 1 (Option D)

Best of Luck!

Answer:

3,500

Step-by-step explanation:

The solutions to the quadratic equation are x= 0.22 and x= -0.22.

The given quadratic formula is 2x²-5x+1=0.

The roots of a quadratic equation ax² + bx + c = 0 are given by x = [-b ± √(b² - 4ac)]/2a.

Here, x= [5± √(25 - 4×2×1)]/2×2

x= [5± √(25 - 8)]/4

x= (5± √17)/4

x= (5± 4.12)/4

x= 0.88/4 and x= -0.88/4

x= 0.22 and x= -0.22

Therefore, the solutions to the quadratic equation are x= 0.22 and x= -0.22.

Step-by-step explanation:

You need to add all of numbers together and then divide by the total number of numbers.

Final answer:

The function y = 2x is linear and without a period, whereas the function y = sin x is periodic with a period of 2π radians.

Explanation:

The period of a function is the length of the interval over which it repeats.

The function y = 2x is a linear function, not a periodic function, and thus does not have a period.

In contrast, the function y = sin x is a periodic function and has a period of 2π radians.

This means that the sine function repeats its values every 2π radians.

Therefore, when comparing the period of these two functions, we can conclude that y = 2x does not have a defined period, while y = sin x has a period of 2π radians.

Answer:

The proportion of the volume of the cone to the volume of the pyramid is: 3.14 times bigger.

Step-by-step explanation:

Given the information of the cone:

=> the volume of the cone

= 1/3π[tex]r^{2} *h[/tex]

= 1/3*3.14*[tex]5^{2} *12[/tex]

= 314 cubic inches

Given the information of the pyramid:

=> the volume of the pyramid:

= 1/3*Bh            (where B is the area of the base)

= 1/3*5*5*12

= 100 cubic inches

The proportion of the volume of the cone to the volume of the pyramid is:

= 314 /100

= 3.14 times bigger.

Answer:

x= -57

Step-by-step explanation:

7x-63+8x-6

-x-63-7

-x=57

x=-57

Answer:

x = -57

Step-by-step explanation:

Simplify both sides of the equation:

Distribute:

(7)(x) + (7)(-9) = 8x + -6

7x + -63 = 8x -6

7x - 63 = 8x - 6

Subtract 8x from both sides

7x−63−8x=8x−6−8x

−x − 63 = −6

Add 63 to both sides

−x − 63 + 63 = −6 + 63

-x = 57

Divide both sides by -1

-x / -1 = 57 / -1

Therefore, you get x = -57

interquartile range = upper quartile - lower quartile

first, order the scores from least to greatest

55, 58, 65, 66, 70, 72, 81

thus, UQ = 72 and LQ = 58

IQR = UQ - LQ = 72 - 58 = 14

Answer:

interval level of measurement

Step-by-step explanation:

Interval level of measurement is numeric and allows for mathematical operations like mean. It is quantitative and in fixed units, i.e changes in values are as a result of a phenomenon. It does not have a zero point i.e a value of zero does not mean what you are measuring is absent, for example a temperature of 0°C do not mean there is no heat applied. It specifies the distance between intervals.

If I were a college professor taking a survey of how many hours of homework students were assigned and I wanted to organize the data by hour ranges, the visual tool that I would use is C) a frequency table.

A frequency table would be the best visual tool to organize students in hour ranges for a survey of how many hours of homework students were assigned.

A frequency table is a way to organize data into different intervals, or ranges, and count how many data points fall into each interval. In this case, I would create intervals such as 0-1 hour, 1-2 hours, 2-3 hours, and so on, and then count the number of students assigned homework in each interval. This would give me a clear picture of the distribution of homework hours among the students. Therefore the correct answer is C) a frequency table.

Answer:

In the picture attached, the function f(x) = -x² + 4x - 3 is shown.

Based on the graph of the function, the following statements are true:

Final answer:

The distance between the points (-5,3) and (1,-1) is found using the distance formula and is approximately 7.2 units when rounded to the nearest tenth.

Explanation:

To find the distance between two points (-5,3) and (1,-1), we can use the distance formula: √((x2 - x1)² + (y2 - y1)²). Plugging in our values, we get the distance as √((1 - (-5))² + (-1 - 3)²) = √(6² + (-4)²) = √(36 + 16) = √52. To round to the nearest tenth, we calculate √52 and find it is approximately 7.2. Therefore, the distance between the points, rounded to the nearest tenth, is 7.2 units.

The question is about the difficulty in satisfying multiple chemical conditions at once, particularly kinetically favorable conditions and thermodynamically stable conditions, which is a complex task often tested in advanced placement chemistry exams.

The question pertains to the challenges associated with satisfying multiple conditions simultaneously in the context of a Chemistry Advanced Placement (AP) Examination. Students often find it difficult to address complex problems where multiple variables must be considered and optimized at the same time. In chemistry, achieving this can involve understanding and balancing various principles such as reaction rates, equilibrium positions, and thermodynamic stability.

In reference to the AP Chemistry exam, students might come across questions that require not just recall of facts or formulas but also the application of these in dynamic scenarios. For instance, satisfying both the kinetic and thermodynamic requirements in a chemical reaction is often challenging. This is because conditions favorable for kinetics, which may involve higher temperatures to increase reaction rates, might adversely affect the thermodynamics by shifting the equilibrium away from the desired products. On the other hand, conditions that favor thermodynamic stability might result in slower reaction rates. Therefore, finding a balance where both kinetics and thermodynamics conditions are optimized is a complex task and is a concept featured in advanced placement chemistry content.

The examination of such complex issues can involve analyzing various aspects and outcomes of a reaction, predicting how changes in conditions could influence the course of the reaction, and understanding the conceptual underpinnings that govern these processes. It is a clear representation of the depth and detail expected at the college level of chemistry education, particularly AP level studies.
