The new equation of the function y = 2^x + 4 shifted 10 units to the left is y = 2^(x-10) + 4

translation moves a shape left, right, up, or down but does not turn. The translated shapes (or the image) appear to be the same size as the original shape, indicating that they are congruent.

Since the function is shifted 10 units to the left, it means the x coordinate of the function is reduced by 10.  making the exponent (x) to become (x - 10)

So the function's new equation is y = 2^(x-10) + 4

Answer:

C (8,6)    A (2,14)

Step-by-step explanation:

(2+m)/2 = 5

2(2+m)/2 = 5 x 2

2+m = 10

m = 10 - 2

m = 8

(-6+n)/2 = 0

2(-6+n)/2 = 2 x 0

-6 + n = 0

n = 6

(-8+x)/2 = -3

2(-8+x)/2 = -3 * 2

-8 + x = -6

x = -6 + 8

x = 2

(-2+y)/2 = 6

2(-2+y)/2 = 6 * 2

-2 + y = 12

y = 12 + 2

y = 14

One assumption underlying linear regression is that the x values are normally distributed.

This above statement is true.

Linear regression is a linear approach for modeling the relationship between a scalar response and one or more explanatory variables (also called dependent and independent variables). When there is one explanatory variable, it is called simple linear regression. If there are more than one, the process is called multiple linear regression. This concept differs from multivariate linear regression, which predicts multiple correlated dependent variables instead of a single scalar variable.

In linear regression, relationships are modeled using a linear predictor function in which the unknown model parameters are estimated from the data. Such models are called linear models. Most commonly, the conditional mean of the response is assumed to be an affine function of the values ​​of the explanatory variables (or predictors) given those values. In rare cases, a conditional median or another quantile is used. Like all forms of regression analysis, linear regression focuses on the conditional probability distribution of the response variable given the values ​​of the predictor variables, rather than the joint probability distribution of all variables, which is the domain of multivariate analysis.

1. Weekly Exogeneous:

It means that we can treat the predictor variable x as a fixed value rather than as a random variable. This means, for example, that the predictor variables are assumed to be error-free, ie not contaminated with measurement error. This assumption is not realistic in many situations, but omitting it makes the within-variable error model much more difficult.

2. Linearity:

This means that the mean response variable is a linear combination of the parameters (regression coefficients) and the predictor variables. . The predictor variables themselves can be arbitrarily transformed. In fact, we can add multiple copies of the same underlying predictor variable, each transformed differently.

3. Constant variance or Homogeneity:

This means that the error variance does not depend on the values ​​of the predictor variables. Therefore, for any given fixed value of the predictor, the variability of the response is the same no matter how large or small the response is. This is often not the case because variables with large mean values ​​usually have more variance than variables with small mean values.

4. Independence from:

This assumes that the response errors are uncorrelated. (True statistical independence is a stronger condition than just lack of correlation and is often unnecessary, but can be exploited when it is known to hold.) Generalized least squares, etc. Some methods in can handle correlated errors, but this usually requires significantly more data unless some kind of regularization is used to bias the model to accept uncorrelated errors Bayesian linear regression is a popular method for handling this problem.

5. Lack of Multicollinearity:

Predictors are not fully multicollinear. For the standard least-squares estimation method, the design matrix X must have perfect column rank p. Otherwise, the predictors are perfectly multicollinear, meaning there is a linear relationship between two or more predictors. This can be caused by erroneously duplicating variables in the data, using linear transformations of the variables together with the original variables, or using multiple variables in the model. It can be caused by inserting a linear combination. as their average. It is also possible that too little data is available relative to the number of estimated parameters.

Answer:

It is difficult to give a precise answer without more information, such as the thickness of the sauce and the desired coverage. However, if we assume that the sauce is being applied evenly and that a thin layer is desired, the amount of sauce needed to cover a 16" pizza would be approximately 50.24 in2. This is because the area of a circle with a diameter of 16" is approximately 50.24 in2. To calculate the area of a circle, you can use the formula A = πr^2, where A is the area, π is approximately 3.14, and r is the radius of the circle (which is half the diameter). In this case, the radius would be 8" and the area would be approximately 50.24 in2.

Answer:

In the linear function equation y = -7x + 1, the value of m (the slope of the line) is -7. The slope of a line represents the rate at which the y-value changes as the x-value changes. In this case, for every unit increase in the x-value, the y-value decreases by 7 units. Therefore, the function has a rate of -7.

To find the slope of a line from a linear function equation, you can use the formula m = (y2 - y1)/(x2 - x1), where (x1, y1) and (x2, y2) are two points on the line. In this case, we can choose any two points on the line and substitute their coordinates into the formula to find the slope. For example, if we choose the points (1, -6) and (2, -13), we get:

m = (-13 - (-6)) / (2 - 1) = -7

Alternatively, we can use the fact that the slope of a line is equal to the coefficient of the x-term in the linear function equation. In this case, the coefficient of the x-term is -7, so the slope of the line is also -7.

Step-by-step explanation:

By using the quadratic equation that can be written with the given information:

x² -7x + 10 = (x - 5)*(x - a)

We will see that the length is:

L  = x - 2

Remember that for a rectangle of length L and width W, the area is given by the product:

A = L*W

Here we know that:

The area is: x² -7x + 10

The width is: x -5

The length will be another factor of the quadratic equation, and we know that it should be of the form:

(x - a)

Using the area formula, we will get:

x² -7x + 10 = (x - 5)*(x - a)

Expanding the right side we get:

x² -7x + 10 = x² -5x -ax + 5a

x² -7x + 10 = x² + (-5 - a)*x + 5a

Comparing like terms, we can see that:

-5 - a = -7

5a = 10

The solution of both of these is:

a = 7 - 5 = 2

a = 10/5 = 2

Then the length of the rectangle is:

If the numbers denoting the perimeter and area of the square are equal, the length of the diagonal will be 4√2 units.

What are Area and Perimeter?

An object's shape defines a region as its area. The area of a figure or any other two-dimensional geometric shape is how much space it takes up in a plane.

The whole length encircling a shape is referred to as its perimeter. Simply put, if a shape is stretched into a linear form, its perimeter is its length. In a two-dimensional plane, a shape's perimeter is the sum of its total dimensions.

Let the side of the square to be 'a'.

If Area and Perimeter of a square are equal then,

So,  Area = Perimeter

      a^2 = 4a

we get, a = 4 units.

Now, we can find the diagonal by using Pythagoras theorem,

Answer:

o answer this question, we need to apply the transformations in the reverse order. So first, we need to apply the translation according to the rule (x+3,y-3). This means that the coordinates of the triangle will become A'(7,2), B'(0,3), and C'(2,5). Next, we need to reflect the triangle across the line y=0. This means that the y-coordinates of the triangle will become negative. So the coordinates of the triangle will become A''(7,-2), B''(0,-3), and C''(2,-5). Finally, we need to rotate the triangle 90 degrees. In a standard cartesian coordinate system, a rotation of 90 degrees counterclockwise is equivalent to the transformation (x, y) -> (-y, x). So the final coordinates of the triangle will be A'''(-2,7), B'''(-3,0), and C'''(-5,2).
