What is the scale factor???

The best-fitting exponential function through the given data points is approximately y = 2.089e^(0.575x).

To find the best-fitting exponential function, we need to determine the values for the base (a) and exponent (b) in the form y = ae^(bx), where y is the dependent variable and x is the independent variable. We can use a method called least squares regression to estimate these values.

By applying least squares regression to the given data points, we can find the exponential function that minimizes the sum of the squared differences between the actual y-values and the predicted y-values. Using this method, we can find the best-fitting exponential function that represents the data.

After performing the regression analysis on the given data points, the best-fitting exponential function is found to be approximately y = 2.089e^(0.575x). This means that the base (a) is approximately 2.089, and the exponent (b) is approximately 0.575. The function can be used to estimate the y-values corresponding to different x-values, providing a model that closely fits the given data points.

Answer:

GH = 11

Step-by-step explanation:

Triangle KGJ is a mini version (I don't remember my terminology, it's been years) of Triangle KHI.

This means that the ratio between the sides on Triangle KGJ should be the same as the ratio between the sides on Triangle KHI.

KJ/KG  =  KI/KH

48/22  =  (48 + 24) / (22 + GH)

48/22  =  72 / (22 + GH)

(48/22) * (22 + GH)  =  72

22 + GH  =  72 / (48/22)

GH  =  [72 / (48/22)] - 22

GH  = [72 * (22/48)] - 22

GH = [72 * 22 / 48] - 22

GH = [1584 / 48] - 22

GH = [33] - 22

GH = 11

The frequency table would have three classes, one for each digital music player option.

When summarizing the consumer responses with a frequency table, the frequency table would have 3 classes.

Frequency table:

A frequency table is a statistical tool that is used to organize raw data in a clear and concise manner.

It is a way of representing the information contained in the data so that it can be easily interpreted and analyzed.

A frequency table is often used to summarize categorical data, such as the data collected in a marketing study like the one mentioned in the question.

The marketing study in this question involved asking 100 consumers to select the best digital music player from three options:

the iPod Touch, Sony Walkman, and Zune HD.

To create a frequency table from this data, we would need to count the number of times each option was chosen by the consumers.

This can be done by grouping the data into classes, which are categories that are created based on the values in the data.

For this particular study, there are only three options to choose from, so there are only three possible classes:

iPod Touch, Sony Walkman, and Zune HD. We would simply count the number of times each option was chosen and record it in the appropriate class.

The resulting frequency table would look something like this: Digital Music Player Frequency i Pod Touch 45 Sony Walkman 28 Zune HD27

Considering the total of peas is 72, Sally's initial number of peas was 56.

Assuming the two brothers did not eat any peas, the total of peas both at the beginning and end is 72 peas.

By the end, Sally has 25 peas and Will has 72 peas.

Before the mother declared none of them would have dessert Sally had given Will half of her peas. This means 25 peas represent half of the peas:

25 x 2 = 50 peas        22 peas in Will's plate

Before this, Will had given Sally half of his peas

22 peas x 2 = 44 peas              28 peas on Sally's plate

Right before this, Sally gave Will half of her peas:

Answer:

Step-by-step explanation:

It is actually easier to ignore the left side for now, and work with the right side. The secant function can be represented in terms of cosine by putting a one over cosine. This relation below should be known:

\(sec(x)=\frac{1}{cos(x)}\)

So, if we replace the secants on the right with the above relation, you can make the right side in terms completely of cosine.

\(\frac{1-cos(x)}{1+cos(x)} =\frac{\frac{1}{cos(x)}-1 }{\frac{1}{cos(x)} +1}\)

I hope that's clear to see. Brainly equations are pretty small and blurry.

The next step is to get a common denominator for the right side. The term '1' is equivalent to cos(x)/cos(x). So we have the following:

\(\frac{1-cos(x)}{1+cos(x)} =\frac{\frac{1}{cos(x)}-\frac{cos(x)}{cos(x)} }{\frac{1}{cos(x)} +\frac{cos(x)}{cos(x)} }\)

Looks rather complex, but it simplifies everything by a lot. Combine it into one single fraction:

\(\frac{1-cos(x)}{1+cos(x)} =\frac{\frac{1-cos(x)}{cos(x)} }{\frac{1+cos(x)}{cos(x)} }\)

When you divide by a fraction, it is equivalent to multiplying by the reciprocal. This is an algebra 1 concept, so it should be familiar:

\(\frac{1-cos(x)}{1+cos(x)} =\frac{1-cos(x)}{cos(x)}*\frac{cos(x)}{1+cos(x)}\)

As you can see, the cos(x)'s will cancel, leaving:

\(\frac{1-cos(x)}{1+cos(x)} =\frac{1-cos(x)}{1+cos(x)}\)

The zeros of the polynomial f(x) = x²(x + 1)(x - 7) are x = 0, x = -1, and x = 7.

A polynomial is a mathematical expression containing more than one term with the variables and constants raised to different powers.

A zero of a polynomial function is a number that makes the function value equal to zero. If f(x) is a polynomial function and k is a real number, then k is said to be a zero of f(x) if and only if f(k) = 0.We can solve for the zeros of the given polynomial by equating f(x) to zero and then factoring the expression further as follows: 0 = x²(x + 1)(x - 7)

For this equation to hold true, either of the factors on the right-hand side must be zero.x² = 0 or x + 1 = 0 or x - 7 = 0.Solving each of the above equations, we get the following roots: x = 0, -1, 7.Thus, the zeros of the polynomial f(x) = x²(x + 1)(x - 7) are x = 0, x = -1, and x = 7.

25 + 11t

Step-by-step explanation:

Total wage = fixed wage + variable wage

Fixed wage = $25

Variable wage depends on tips from a number of tables

Abigail gets $11 in tip per table

Let t = number of tables

Variable wage = 11t

Total wage = 25 + 11t

How much would Abigail expect to earn in a day on which she

waits on 17 tables?

Total wage = 25 + 11t

= 25 + 11(17)

= 25 + 187

= $212

Abigail will earn a total of $212 if she waits on 17 tables each day

How much would Abigail expect to make in a day when

waiting on t tables?

Total wage = 25 + 11t

When t = t

Total wage = 25 + 11t

Abigail will earn a total of 25 + 11t if she waits on t tables each day

The sequence an = √(n+2) converges to 1.

To determine whether the sequence converges, we need to find its limit. As n approaches infinity, the term √(n+2) will approach 1. This can be observed by considering the behavior of the expression √(n+2) as n gets larger. For sufficiently large values of n, the "+2" term becomes insignificant compared to n, and the square root of n dominates the expression. Since the square root of n approaches infinity as n approaches infinity, the sequence converges to 1.

To provide a more formal proof, we can use the definition of convergence. Let ε > 0 be given. We need to find an N such that for all n > N, |√(n+2) - 1| < ε.

Manipulating the inequality, we have |√(n+2) - 1| = |√(n+2) - 1| × |√(n+2) + 1| / |√(n+2) + 1|. Simplifying this, we get |(n+2) - 1| / |√(n+2) + 1|. Since |n+2 - 1| = |n+1| = n+1 for n > 0, we have (n+1) / |√(n+2) + 1|.

Now, for n > 0, we have n+1 < n+2, and |√(n+2) + 1| > 1. Thus, (n+1) / |√(n+2) + 1| < n+2. Setting N = ε - 2, for all n > N, we have |√(n+2) - 1| < ε, proving the convergence of the sequence to 1.

The expression used to find the change in temperature per hour is Algebraic expression

Thus per hour; the temperature falls at the rate of \(- 3\dfrac{1}{2}^0\)

Step-by-step explanation:

A temperature falls from 0 to  \(- 12\dfrac{1}{4}\)     in     \(3\dfrac{1}{2} \ hours\)

Which expression finds the change in temperature per hour.

From the above given information;

The initial temperature is 0

The final temperature is  \(- 12\dfrac{1}{4}\)  

The change in temperature is \(\Delta T = T_2 - T_1\)

\(\Delta T = -12\dfrac{1}{4} -0\)

\(\Delta T = -12.25\)

Thus;

-12.25 ° = 3.5 hours

To find the change in x°   per hour; we have;

x°            = 1 hour

The expression used to find the change in temperature per hour is Algebraic expression

From above if we cross multiply ; we have;

(- 12.25° × 1 hour) = (x° × 3.5 hour)

Divide both sides by 3.5 hours; we have:

\(\dfrac{-12.25^0*1 }{3.5}=\dfrac{ x^0 *3.5}{3.5}\)

x° =  - 3.5

x° = \(- 3\dfrac{1}{2}\)

Thus per hour; the temperature falls at the rate of \(- 3\dfrac{1}{2}^0\)

The area of the parallelogram is \(\sqrt{132}\).

A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length, and the opposite angles are equal in measure. Also, the interior angles on the same side of the transversal are supplementary. Sum of all the interior angles equals 360 degrees.

Given that,

vertices k(1, 1, 3), l(1, 3, 5), m(6, 9, 5), and n(6, 7, 3)

Area of Parallelogram = |KL × KN|

KL = (1, 1, 3) - (1, 3, 5) = (0, 2, 2)

KN = (1, 2, 3) - (3, 7, 3) = (2, 5, 0)

Area of the parallelogram = cross product of two vectors, represented by the adjacent sides.

Area of Parallelogram = |(0, 2, 2) × (2, 5, 0)|

                                    = |i(2 × 0 - 5 × 2) - j(0 × 0 - 2 × 2) + k(0 × 5 - 2 × 2)|

                                    = |i(-10) - j(-4) + k(-4)|

                                    = |-10i + 4j - 4k|

                                    = \(\sqrt{(-10)^{2}+(4)^{2}+(-4)^{2} }\)

                                    = \(\sqrt{100+16+16}\)

                                    = \(\sqrt{132}\)
