$f(x)=2( \sqrt[3]{27})^{2x}$

Here 2 on left most side is the coefficient, 2x is the exponent and the of the function is cube root of 27.

So,

$Base= \sqrt[3]{27} \\ \\ 
Base= \sqrt[3]{3^{3} } \\ \\ 
Base=3$

Thus, the simplified base for the function is 3. So correct answer is option B

A polynomial p has zeros when x = 5, x = -1, and x = -1/4

mafiozo [28]

Answer:

$x=5$ ⇒ $(x-5)=0$

$x=-1$ ⇒ $(x+1)=0$

$x=-1/4$ ⇒ $(x+1/4)=0$ ⇒ $(4x+1)=0$

$p(x)=(x-5)(x+1)(4x+1)=0$

$Option(B)$

Hope it helps...

Have a great day!!

Which of the following statements about least squares regression analysis is true?

Lemur [1.5K]

The statements about least squares regression analysis is true are I and III.

<h3>What is meant by regression analysis?</h3>

The statistical technique of regression analysis demonstrates the link between two or more variables. The method evaluates the relationship between a dependent variable and independent factors, and is frequently presented as a graph.

You can anticipate the effects of the independent variable on the dependent one by creating a regression analysis. For instance, we can claim that a linear regression model can adequately account for age and height.

Here,

From the given information in the question:

The statements I and III are correct.

And the statements are:

A point with a large residual is an outlier and the removal of an influential point from the data set could change the value of the correlation coefficient.

So, the statements I and III are correct for the given information in the question.

Anton defines an acute angle as an angle that is not obtuse. Is Anton's definition valid ?

kobusy [5.1K]

Answer:

Anton's definition is not valid.

Step-by-step explanation:

We have been given that Anton defines an acute angle as an angle that is not obtuse. We are asked to find whether Anton's definition is valid or not.

We know that an angle is known as acute angle whose measure is greater than 0 and less than 90 degrees.

We also know that an angle is known as obtuse angle whose measure is greater than 90 degrees and less than 180 degrees.

We know that a right triangle is neither acute nor obtuse. Since Anton hasn't mentioned a right triangle to his definition, therefore, his definition is not valid.
