re The point-slope form of a line is

The slope m of the line passing through these two points is the difference between their y coordinates divided by the difference between their x - coordinate.

Now we need only find the y-intercept.

Let us use the point (3, 4) which tells us that at x = 3, y = 4; therefore,

Hence, the question of our line in point-slope form is

Alternatively, when we have the slope of the line we would just use one of the points to quickly write the point-intercept form.

The y_1 and x_1 in the very first equation are the coordinates of one of the points on the line =. We know that one of the point on our line is (3, 4);

so you write 16 but i don't speak English very good i want help you 2(6+3)-2 ok you you going multiplying 2×6=12+6=18-2=16 so 16

The proportional relationship between the number of centerpieces and the total cost for the centerpieces is graphed at the end of the answer.

A graph represents a proportional relationship if the output variable y in the y-axis is written as a product of the input variable x in the x-axis and the constant of proportionality k, as follows:

y = kx.

The constant k is called the slope of the unit rate of the situation, measuring by how much y changes when x changes by 1.

In the context of this problem, the cost of each centerpiece is of $5.50, hence the constant is given as follows:

y = 5.5x.

The number of centerpieces cannot be negative, hence the domain of the relation is given as follows:

x ≥ 0.

Considering this domain, the graph of the relation is given at the end of the answer.

There are 1680 ways the teaching assistants can be chosen to grade the exam.

To determine the number of ways the teaching assistants can be chosen to grade the exam, we need to consider the number of choices available for each question and multiply them together.

For the first question, there are eight teaching assistants available. Therefore, there are 8 choices for the first question.

For the second question, since one assistant has already been assigned to the first question, there are seven remaining assistants available. Thus, there are 7 choices for the second question.

Similarly, for the third question, there are six remaining assistants available after two have been assigned to the previous questions. Hence, there are 6 choices for the third question.

Lastly, for the fourth question, there are five remaining assistants available after three have been assigned to the previous questions. Therefore, there are 5 choices for the fourth question.

To determine the total number of ways, we multiply the number of choices for each question:

Total ways = 8 * 7 * 6 * 5 = 1680

Therefore, there are 1680 possible approaches to select the teaching assistants to grade the exam.

Answer: arithmetic

Step-by-step explanation: arithmetic cause is repeating its self

The vertex form of the given quadratic equation is.

y = -5(x + 6)² - 356

To complete squares we need to use the perfect square trinomial:

(a + b)² = a² + 2ab +b²

Here we can rewrite our quadratic as follows:

y = -5x² - 60x - 176

y = -5*( x² + 12x) - 176

y = -5*( x² + 2*6x) - 176

Now we can add and subtract 6² = 36 then we will get:

y = -5*( x² + 2*6x + 36 - 36) - 176

y = -5*( (x + 6)² - 36) - 176

y = -5(x + 6)² - 356

Which means that the vertex is at (-6, -356)

To evaluate the results for your area and identify the emerging trends from the data, we need to examine the relationships between different variables. Based on the options provided:

a. Increased Overtime Hours lead to increased Productivity Rates: This trend suggests that as the number of overtime hours increases, productivity rates also increase. However, without specific data and analysis, it is difficult to confirm this trend.

b. Productivity Rate is negatively impacted by team size: This trend indicates that larger team sizes result in lower productivity rates. This suggests that as the team size increases, individual performance and coordination may be compromised, leading to decreased productivity.

c. Schedule Adherence is inconsistent across periods of time: This trend suggests that adherence to schedules fluctuates over time. It indicates that there is variability in meeting scheduled timelines or deadlines, potentially due to factors such as workload, resource availability, or changing priorities.

d. Larger teams have more Schedule Adherence issues: This trend implies that larger teams face challenges in adhering to schedules. It suggests that coordination and communication within larger teams may be more complex, leading to difficulties in meeting scheduled timelines or maintaining adherence.

It is important to note that without specific data and statistical analysis, it is challenging to determine the accurate trend from the given options. Proper data analysis and interpretation would be required to draw definitive conclusions about the relationships between variables in your specific area.

Step-by-step explanation:

You see, in a standard form the term with greater stays at the very right.

Therefore, the diameter of the circle with an area of pi is 2. We can round this to the nearest tenth to get 2.0, since there are no decimal places beyond the first digit after the decimal point. Thus, the diameter of the circle is 2.0.

To find the diameter of a circle with an area of pi, we need to use the formula for the area of a circle which is A = πr^2, where A is the area of the circle, π is pi, and r is the radius of the circle.

Since we are given the area of the circle as pi, we can substitute that into the formula as follows:A = πr^2pi = πr^2Dividing both sides of the equation by pi gives us

:r^2 = 1r = sqrt(1)

Since the radius is equal to the square root of 1, which is 1, we can now use the formula for the diameter of a circle to find the diameter. The formula for the diameter of a circle is

20 meters is in one Pacer lap for MUSD PFT assessment.

The objective of the PACER is to run as long as possible while keeping a specified pace. Students run back and forth across a 20-meter space at a pace that gets faster each minute. A point is scored for each 20-meter distance covered. The test is easier in the beginning but progressively gets more difficult. In comparison to distance running, the pacer is a more effective, fun, and easy way to measure aerobic capacity that encourages participation from all youth and is relatively easy to score and administer. It is a part of the fitness gram and Brockport test battery.

The running speed for each level is same for the 15m and 20m tests, though the number of laps for each level is greater for the 15m test, so that each level is still approximately one minute in duration.

The duration of the randomly selected class (C) is approximately 53.2 minutes, rounded to one decimal place.

To find the duration (C) of a randomly selected class with a continuous uniform distribution between 49.2 minutes and 55.5 minutes, given that P(X > C) = 0.29, we can use the formula for the probability of a continuous uniform distribution:

P(X > C) = (B - C) / (B - A)

Here, A is the lower bound (49.2 minutes), B is the upper bound (55.5 minutes), and P(X > C) is the probability of the class duration being longer than C minutes (0.29). Plugging in the values:

0.29 = (55.5 - C) / (55.5 - 49.2)

Now, solve for C:

0.29 * (55.5 - 49.2) = 55.5 - C
C = 55.5 - (0.29 * 6.3)
C ≈ 53.2 minutes

Step-by-step explanation:

\( = > 3 - 7c - 20c = 7( - 7c - 19) + 14c \\ \\ = > 3 - 27c = ( - 7c \times 7) - (7 \times 19) + 14c \\ \\ = > 3 - 27c = - 49c - 133 + 14c \\ \\ = > 3 - 27c = - 35c - 133 \\ \\ = > 3 - 27c + 35c = - 133 \\ \\ = > 3 + 8c = - 133 \\ \\ = > 8c = - 133 - 3 \\ \\ = > 8c = - 136 \\ \\ = > c = - \frac{136}{8} \\ \\ = > c = - 17\)

Answer:

c = -17

Step-by-step explanation:

→Distribute the 7 to (-7c - 19):

3 - 7c - 20c = -49c - 133 + 14c

→Add like terms (-7c and -20c, -49c and 14c):

3 - 27c = -35c - 133

→Add 35c to both sides:

3 + 8c = -133

→Subtract 3 from both sides:

8c = -136

→Divide both sides by 8:

c = -17

3/2

he buys 6 parts white but we don't know how much black paint we need so we can set this equal to each other like so:

\(\frac{3}{2} = \frac{6}{x}\)

the 6 parts white is set equal to 3 parts white now we cross multiply to find x

3x = 12

x = 4

alternatively you could also just divide 6 by 3, you get 2 then multiply 2 by 2(black paint) and you would get the same answer

Answer:

x = 121°

Step-by-step explanation:

∠ 1 + 115° = 180°

∠ 1 = 180 - 115

∠ 1 = 65°

∠ 2 + 304° = 360°

∠2 = 360 - 304

∠ 2 = 56°

∠ 1 + ∠ 2 + ∠ 3 = 180°

65° + 56 ° + ∠ 3 = 180°

∠3 = 180 - 65 - 56

∠ 3 = 59°

∠3 + x = 180°

59° + x = 180°

x = 180 - 59

x =  121 °
