What properties of dilations and rigid transformations define similarity?

Mathematics

iren2701 [21]3 years ago
8 0

Two figures are similar if one can be mapped onto the other by rigid rotation, reflection, and translation. Two figures are similar if one can be mapped onto the other by rotation, reflection, translation, or dilation/rescaling. That is, they're similar if one is congruent to a rescaling of the other.

What is the average rate of change of the function in the table at the interval x = -1 to x = 1?
Andre45 [30]

Answer:

the answer is undefined

Step-by-step explanation:

If a function, f(x), is continuous (that is, has values for every x in the interval) from x=- 1 to x=1 ), then the average rate of change is:( total amount that f(x) changes ) / (total amount that x changes)( f(1) - f(-1) ) / ( (1) - (-1) )( f(1) - f(-1) ) / 2The variable x changes from (-1) to (1). That value is 2. [note: (1)-(-1) ]The function changes from f(-1) to f(1). You must determine f(1)-f(-1) and use that value as the numerator.Fill in the values to determine the average rate of change: ( f(1) - f(-1) ) / 2However, if the plot of y values is not a function, and there is some x value between -1 and 1 for which f(x) is undefined, then the rate of change of y from f(-1) to f(1) is also undefined.

For each of parts (a) through (d), indicate whether we would generally expect the performance of a flexible statistical learning
olga_2 [115]

Step-by-step explanation:

First, note that a flexible statistical learning method refers to using models that take into account agree difference in the observed data set, and are thus adjustable. While the inflexible method usually involves a model that has no regard to the kind of data set.

a) The sample size n is extremely large, and the number of predictors p is small. (BETTER)

In this case since the sample size is extremely large a flexible model is a best fit.

b) The number of predictors p is extremely large, and the number of observations n is small. (WORSE)

In such case overfiting the data is more likely because of of the small observations.

c) The relationship between the predictors and response is highly non-linear. (BETTER)

The flexible method would be a better fit.

d) The variance of the error terms, i.e. σ2=Var(ϵ), is extremely high. (WORSE)

In such case, using a flexible model is a best fit for the error terms because it can be adjusted.

kvasek [131]

Answer:

<u><em>$225,000.</em></u>

Step-by-step explanation:

The equation to solve for the amount Irwin made would be y (The amount Irwin made) = x-135,000.

The amount Irwin made is 360000-135000= $225,000.

if you can mark brainliest that would be great
