Solve for c. law of cosines

The answer is C: A power model would best represent the relationship because scatterplot C is fairly linear.

In this the rate of change of the dependent variable is proportional to the power of the independent variable. In other words, when the independent variable increases, the dependent variable increases at a rate that is proportional to the power of the independent variable. This type of model is often used to describe phenomena such as population growth, economic growth, and physical processes such as diffusion.

When looking at the graph of scatterplot C, it is clear that the relationship between time and volume follows a power model.

The data points in the graph are fairly linear, meaning that as the log of time increases, the log of volume increases at a rate that is proportional to the power of the log of time.

This indicates that a power model would best represent the relationship between time and volume, making C the correct answer.

Step-by-step explanation:

the image of point (-12, -12) after a dilation by a scale factor of 1/4 centered at the origin is (-3, -3).

How to find?

To find the image of point (-12, -12) after a dilation by a scale factor of 1/4 centered at the origin, we can use the following formula:

(x', y') = (kx, ky)

where (x, y) are the coordinates of the original point, (x', y') are the coordinates of the image after dilation, and k is the scale factor.

In this case, the scale factor is 1/4 and the center of dilation is the origin (0, 0). Therefore, we have:

x' = (1/4) × (-12) = -3

y' = (1/4) × (-12) = -3

So the image of point (-12, -12) after a dilation by a scale factor of 1/4 centered at the origin is (-3, -3).

Answer:

y = 3x - 7

Step-by-step explanation:

We can use the two-point form formula to find the equation of a line that passes through two given points (x1, y1) and (x2, y2):

y - y1 = (y2 - y1) / (x2 - x1) * (x - x1)

where (x1, y1) and (x2, y2) are the two points and (x, y) represents any point on the line.

Using the given points, we have:

x1 = 1, y1 = 10

x2 = -4, y2 = -5

Substituting these values into the formula, we get:

y - 10 = (-5 - 10) / (-4 - 1) * (x - 1)

Simplifying the equation, we have:

y - 10 = 3(x - 1)

Expanding and rearranging, we get:

y = 3x - 7

Therefore, the equation of the line that passes through (1, 10) and (-4, -5) is y = 3x - 7

By answering the presented question, we may conclude that Therefore, trapezium the height of the trapezoid is 71.5 centimeters.

A trapezium is a two-dimensional geometric figure with four sides, one pair parallel to the other. It is also called as a trapezium in certain locations. The parallel sides are known as bases, whereas the non-parallel sides are known as legs. The distance between the two bases is the trapezoid's height or altitude. The area of a trapezium is given by A = 0.5 * (b1 + b2) * h, where b1 and b2 are the lengths of the two bases and h is the height.

The revenue, in billions of dollars, for a company in the year 2002 was $2.7 billion. One year later, in 2003, the revenue had risen to $3.4 billion. In 2005, the revenue climbed to $3.9 billion, before falling to $2.7 billion in 2008. The revenue, r, in billions of dollars, for the company, is a quadratic function of the number of years since 2002, x. what is the vertex of the function?

To find the quadratic function that represents the revenue of the company as a function of the number of years since 2002, we can use the vertex form of a quadratic function:

r(x) = a(x - h)^2 + k

where a is the coefficient of the quadratic term, h is the x-coordinate of the vertex, and k is the y-coordinate of the vertex.

We can use the given revenue values to set up a system of three equations:

2.7 = a(0 - h)^2 + k

3.4 = a(1 - h)^2 + k

2.7 = a(6 - h)^2 + k

Subtracting the first equation from the second, and the first equation from the third, we get:

0.7 = a(1 - h)^2

0 = a(6 - h)^2

Since a cannot be zero (otherwise we wouldn't have a quadratic function), we can divide the second equation by the first to get:

6 - h = 10

which gives us h = -4.

Substituting h = -4 into the first equation, we get:

2.7 = a(0 - (-4))^2 + k

2.7 = 16a + k

Substituting the revenue value for 2005, we get:

3.9 = a(3 - (-4))^2 + k

3.9 = 49a + k

Solving for a and k, we get:

a = -0.1

k = 4.3

Therefore, the quadratic function that represents the revenue of the company as a function of the number of years since 2002 is:

r(x) = -0.1(x + 4)^2 + 4.3

The vertex of this function is at (-4, 4.3).

What is the sum of the numbers in the sequence 3, −4, 5, −6, . . . , 101?

We can notice that the sequence alternates between adding an odd number and subtracting an even number. The first term is 3, which is odd, so the sequence starts by adding an odd number. The second term is -4, which is even, so the sequence then subtracts an even number. This pattern continues, so the sum of the sequence can be written as:

3 - 4 + 5 - 6 + ... + 101

We can group the terms into pairs:

(3 - 4) + (5 - 6) + ... + (99 - 100) + 101

Each pair of terms adds up to -1, so we can simplify the expression to:

-1 -1 -1 ... -1 + 101

where there are 50 pairs of -1's. The sum of 50 -1's is -50, so the sum of the sequence is:

-50 + 101 = 51

Therefore, the sum of the numbers in the sequence 3, −4, 5, −6, . . . , 101 is 51.

What is 12 7/8 - 56/17?

To subtract mixed numbers like 12 7/8, we first need to convert it to an improper fraction. We can do this by multiplying the whole number by the denominator of the fraction, and adding the result to the numerator. This gives us:

12 7/8 = (12 × 8 + 7)/8 = 103/8

Now we can subtract 56/17 from 103/8. To do this, we need to find a common denominator for the two fractions. The least common multiple of 8 and 17 is 136, so we can rewrite the fractions with this denominator:

103/8 = (103/8) × (17/17) = 1751/136

56/17 = (56/17) × (8/8) = 448/136

Now we can subtract the two fractions:

1751/136 - 448/136 = (1751 - 448)/136 = 1303/136

We can simplify this fraction by finding a common factor to divide both the numerator and denominator. Since both 1303 and 136 are relatively prime, we cannot simplify it any further. Therefore, the final answer is:

12 7/8 - 56/17 = 1303/136

A circle in the xy-plane has a diameter with endpoints (2,4) and (2,14). An equation of this circle is (x-2)^2+(y-9)^2=r^2 ,where r is a positive constant. What is the value of r?

The center of the circle is the midpoint of the diameter, which is at (2, (4+14)/2) = (2, 9). We can substitute this center point into the equation of the circle to get:

(x - 2)^2 + (y - 9)^2 = r^2

(2 - 2)^2 + (9 - 9)^2 = r^2

0 + 0 = r^2

So we see that r = 0. Therefore, the equation of the circle is just:

(x - 2)^2 + (y - 9)^2 = 0

This describes a single point in the xy-plane, which is the center of the circle. Note that this point is already on the given diameter, so it makes sense that the radius is zero.

which number has which number has the lowest value? 1/6 1/3 - 1/9 1/3 - 1/6 1/4 - 1/6the lowest value?

To compare these fractions, we can first find a common denominator for all of them. The least common multiple of 2, 3, and 4 is 12, so we can rewrite the fractions with this denominator:

1/6 = 2/12

1/3 - 1/9 = (3/12) - (1/12) = 2/12

1/3 - 1/6 = (2/6) - (1/6) = 1/6

1/4 - 1/6 = (3/12) - (2/12) = 1/12

So the fractions can be ordered as follows, from least to greatest:

1/12 < 1/6 < 2/12 = 1/3 - 1/9 < 1/3 - 1/6

Therefore, the fraction with the lowest value is 1/12.

The function f(x) = |-x| is an even function, the equation of the parabola that has vertex at (2, 7) and passes through the point (-1, 3) is y = (-4/9)(x - 2)^2 + 7.

An odd function is a function that satisfies the property f(-x) = -f(x) for all values of x in the function's domain. Geometrically, this means that an odd function is symmetric about the origin.

To determine if the function f(x) = |-x| is an odd or even function, we can use the definition of odd and even functions.

First, let's check if f(-x) = f(x) for all values of x in the domain of the function:

f(-x) = |-(-x)| = |x|

f(x) = |-x|

Since |x| is equal to |-x| for all values of x, we have f(-x) = f(x) for all x in the domain. This means that f(x) is an even function.

2. There are different methods to find the equation of a parabola given its vertex and another point on the curve. One possible way is to use the standard form of the equation of a parabola:

y = a(x - h)^2 + k

where (h, k) is the vertex and a is a constant that determines the shape and orientation of the parabola.

To find a, we can use the fact that the point (-1, 3) lies on the parabola:

3 = a(-1 - 2)^2 + 7

3 = 9a + 7

9a = -4

a = -4/9

Substituting this value of a and the vertex (h, k) = (2, 7) into the equation, we get:

y = (-4/9)(x - 2)^2 + 7

Therefore, the equation of the parabola that has its vertex at (2, 7) and passes through the point (-1, 3) is:

y = (-4/9)(x - 2)^2 + 7

3. To determine whether the function f(x) = 25 - x^3 is even, odd, or neither, we need to find f(-x) and -f(x):

f(-x) = 25 - (-x)^3 = 25 + x^3

-f(x) = -(25 - x^3) = -25 + x^3

Now, let's compare f(-x) and -f(x):

f(-x) = 25 + x^3 ≠ f(x) and f(-x) ≠ -f(x)

-f(x) = -25 + x^3 ≠ f(x) and -f(x) ≠ -f(x)

Since neither f(-x) = f(x) nor f(-x) = -f(x) hold for all x in the domain of f, the function f(x) = 25 - x^3 is neither even nor odd.

4. To determine whether the function f(x) = 72 - x^4 is even, odd, or neither, we need to find f(-x) and -f(x):

f(-x) = 72 - (-x)^4 = 72 - x^4

-f(x) = -(72 - x^4) = -72 + x^4

Now, let's compare f(-x) and -f(x):

f(-x) = 72 - x^4 = f(x)

-f(x) = -72 + x^4 ≠ f(x) and -f(x) ≠ -f(x)

Since f(-x) = f(x) for all x in the domain of f, the function f(x) = 72 - x^4 is even. This means that its graph is symmetric with respect to the y-axis.

The intersection of two numerical axes creates a two-dimensional plane known as a coordinate plane. The x-axis, which is a horizontal number axis, and the y-axis, which is a vertical number axis, are two different types of number axes.

The French mathematician René Descartes enhanced the coordinate plane that had been created centuries earlier. The system is occasionally referred to as the Cartesian coordinate system in his honor. You can doodle points and lines on coordinate planes. With the aid of this method, we may generate and communicate algebraic concepts as well as visually express algebraic relations.

The coordinate plane has a horizontal axis, a vertical axis, and a right angle where numerous straight lines intersect. In a coordinate plane, the horizontal axis is represented by the x axis. The vertical axis is referred to as the y-axis. The origin is the location where the two axes meet. On both the x- and y-axes, the origin is at 0.

As ordered pairs, positions on the coordinate plane are described.

By connecting the position of the point along the x-axis (the first value in the ordered pair) and the y-axis (the second value in the ordered pair), an ordered pair reveals the location of the point.

The first value in an ordered pair, like (x, y), is referred to as the x coordinate, and the second value is referred to as the y coordinate. The x coordinates are presented before the y coordinates; take note of this. The ordered pair of the origin is represented as (0, 0), since it has an ordinate and abscissa of 0.

The measure of each interior angle of a regular octagon is 135°.

An octagon is an eight-sided polygon with eight interior angles, and a regular octagon is an eight-sided polygon with eight interior angles of equal measure (congruent angles) and eight sides of equal length (congruent sides).

An octagon is composed of eight angles that sum to 1080 degrees.

The sum of the interior angles of a polygon with n sides is (n-2)×180°.

To get the interior angle, you must divide the sum of the interior angles by the number of sides.

A regular octagon has eight sides, so to find the measure of each interior angle of a regular octagon, divide the sum of

the interior angles by eight.

Sum of interior angles = (n-2)×180°

                                     = (8-2)×180°

                                    = 6 × 180°

                                    = 1080°
