Step-by-step explanation: PLATO ANSWER I got 100%

To solve the problem we must know about the change of base rule for Logarithm.

What is the change of base rule for Logarithm?

The change of base rule for Logarithm helps us to change the base of any logarithmic expression to any other logarithmic expression.

[tex]log_ab = \dfrac{log_x b}{log_x a}[/tex]

where x is any base.

The expression can be expressed as [tex]\dfrac{log\ 81}{log\ 12}[/tex].

Given to us

[tex]log_{12}81[/tex]

Change of base rule

[tex]log_{12}81\\[/tex]

use the change of base rule, [tex]log_ab = \dfrac{log\ b}{log\ a}[/tex],

[tex]log_{12}81=\dfrac{log\ 81}{log\ 12}[/tex]

Hence, the expression can be expressed as [tex]\dfrac{log\ 81}{log\ 12}[/tex].

When is it appropriate to use the paired t test (involving the mean of the differences)? A. When two independent samples are compared. B. When two dependent samples are compared. C. When four samples are compared at once. D. When any two samples are compared.

Answers

Answer:

B. Two dependent samples are compared

Step-by-step explanation:

We use it when we are comparing Two dependent samples. The paired t-test can be likened to the repeated measures ANOVA test. Both of these two test are useful when comparing how a static group does in different test conditions.

But the difference between these two are:

We use the paired t-test if the explanatory variable has two levels.

While the Repeated measures ANOVA is used when the explanatory variable has greater than two levels.

4. Brett is fencing in a circular patio. The radius of the patio is 70 feet. How many linear feet of
fencing does he need to enclose the patio?

Answers

Answer:

The number of feet of fencing that he needs will be equal to the perimeter of the circular patio.

We know that the perimeter of a circle of radius R is equal to:

P = 2*pi*R

where pi = 3.14

Then if the radius of the patio is 70ft, the perimeter of the patio will be:

P = 2*3.14*70ft = 439.6 ft

Then he needs 439.6 ft of fencing to enclose the patio.

(3) 4x3 – x2 + 3x + 13
(4) 8x3 + 3x + 3​

Answers

Hi there!

[tex]\large\boxed{(3) \text{ } 4x^{3} - x^{2} + 3x + 13}[/tex]

Given:

A = 6x³ - x² + 4x + 8

B = 2x³ + x - 5

Find A - B by subtracting the two equations. Subtract like-terms:

6x³ - x² + 4x + 8 - (2x³ + x - 5)

Simplify:

6x³ - x² + 4x + 8 - 2x³ - x + 5 =

4x³ - x² + 3x + 13. The correct choice is 3.
