Answer:

THis equation is in slope-intercept form (y=mx+b)

in this equation m represents the slope.

Therefore 1/3 is the slope

1/3

Step-by-step explanation:

Answer: m = 1/3

Step-by-step explanation: Since the equation of this line is written

in slope-intercept or y = mx + b form, its slope or m is represented

by the coefficient of the x term which in this case is 1/3.

Answer:

1 2/7 rounded to the nearest whole number is therefore 1

As per the given data, y = 6 cos (3x - 1) + 3 is the function that has an amplitude that is twice the size and a period that is three times the size of the function.

The given function is y = 3 cos (-1x) + 2.

To find a function with an amplitude twice the size and a period three times the size, we can modify the amplitude and period in the original function.

Amplitude:

The amplitude of the original function is 3. To double the amplitude, we multiply it by 2: 3 * 2 = 6.

Period:

The period of the original function is determined by the coefficient of x, which is -1. To make the period three times larger, we divide the coefficient by 3: -1 / 3 = -1/3.

Putting it all together, we have:

y = 6 cos (3x - 1) + 3

Thus, this function has an amplitude of 6 (twice the size of the original function) and a period of 3 times the size of the original function.

Answer:

f(x) = 2(x - 2)^2 - 1

vertex: (2, -1)

Step-by-step explanation:

f(x) = 2x^2 - 8x + 7

First, we find the vertex.

x = -(-8)/4 = 2

y = 2(2)^2 - 8(2) + 7 = 2(4) - 16 + 7 = 8 - 9 = -1

vertex: (2, -1)

Second, we write f(x) in vertex form.

we know that h and k have to be 2 and -1.

2x^2 - 8x + 7 = a(x - 2)^2 - 1

Since 8 - 1 = 7, we do this:

f(x) = (2x^2 - 8x + 8) - 1

Factor out the 2 and then factor the polynomial

f(x) = 2(x^2 - 4x + 4) - 1

factors of 4:

1 4

2 2

-1 -4

-2 -2 = -4

the function in vertex for is:

f(x) = 2(x - 2)^2 - 1

Answer:

This is not a function

Step-by-step explanation:

Assuming that the line in question is parallel with the y axis, by using the line test we can see that the line is not a function. The line test is where you draw straight lines going vertically over the graph and if the lines touch the figure in question more than once that means it's not a function.

This can also be proved by imagining there are 2 different points on the line in question. Since the line is straight vertically that means that the points will share the same x value for different y values, which makes it not a function

Answer:

This is not a function.

Step-by-step explanation:

The questioned parallel line within the y-axis does not meet the requirements to be a function. The line test, as the other person stated, is a test where lines are drawn over the points to determine if the graph / model is, or is not a function. Doing so in this process, if the lines touch the same point more than once, that means the graph is not a function.

The bakery should use the range to determine whether or not the equipment changes have worked. The correct answer is C.

To determine whether the equipment changes made by the bakery have resulted in more uniform-sized muffins, they should use the measure of variability. The most suitable measure, in this case, would be the range.

The range is calculated by finding the difference between the maximum and minimum values in a data set. In this scenario, the bakery made 25 muffins and measured each one. By finding the range of the measurements, they can assess the spread of sizes among the muffins.

Here's how they can use the range to evaluate the effectiveness of the equipment changes:

Collect the measurements of all 25 muffins.

Determine the maximum and minimum measurements.

Calculate the range by subtracting the minimum measurement from the maximum measurement.

If the range of the muffin sizes is smaller compared to the range before the equipment changes, it suggests that the modifications have resulted in more uniform-sized muffins. Conversely, if the range remains similar or larger, it indicates that the changes might not have effectively improved the uniformity of muffin sizes.

Therefore, the bakery should use the range to determine whether or not the equipment changes have worked. The correct answer is C.

The number of ways to pick a digit, a lowercase letter, an uppercase letter, or one of eight allowable punctuation marks is 70.

The total number of digits (0-9) = 10.

Thus, the number of ways to pick a digit = 10.

The total number of lowercase letters (a - z) = 26

Thus, the number of ways to pick a lowercase letter = 26.

The total number of uppercase letters (A - Z) = 26

Thus, the number of ways to pick an uppercase letter = 26.

The total number of allowable punctuation marks = 8

Thus, the number of ways to pick a punctuation = 8.

Hence, the total number of ways to pick a digit, a lowercase letter, an uppercase letter, or one of eight allowable punctuation marks is -

10 + 26 + 26 + 8 = 70.

1/4π radians is approximately equal to 45 degrees.

To convert a value from radians to degrees, multiply the value by 180/π. For example, to convert π/4 radians to degrees, multiply π/4 by 180/π to get 45 degrees. This conversion is useful for converting angles between the two units of measurement.

Degrees = Radians × 180/π.

Therefore, to convert 1/4π radians to degrees, we have:

Degrees = (1/4π) × (180/π) ≈ 45°

Hence, 1/4π radians is approximately equal to 45 degrees.

Answer:

B. 3188.5 cubic inches.

Step-by-step explanation:

The volume of a cone is calculated using the following formula:

Volume = (1/3) * π * r² * h

Where:

In this problem, we are given that r = 17 inches and S.h = 20 inches.

First we need to find height h.

py using Pythagorous theorem,we get

c²=a²+b²

here c= slight height and a is radius

20²=17²+b²

20²-17²=b²

111=b²

b=√(111)

Plugging these values into the formula, we get:

Volume = ⅓*π* 17² *√(111) = 3188.5 cubic inches

Therefore, the volume of the cone is 3188.5 cubic inches.

Answer:

x = 3/2 or x = -1

Step-by-step explanation:

2x² - x - 3 = 0

2*(-3) = -6

Factors of -6:

(-1, 6), (1, -6), (-2, 3), (2, -3)

We need to find a pair that adds up to the co-eff of x which is (-1)

Factors :(2,-3)

2 - 3 = -1

so, 2x² - x - 3 = 0 can be written as:

2x² + 2x - 3x - 3 = 0

⇒ 2x(x + 1) -3(x + 1) = 0

⇒ (2x - 3)(x + 1) = 0

⇒ 2x - 3 = 0 or

x + 1 = 0

⇒ 2x = 3 or x = -1
