Answer:

-5

Step-by-step explanation:

f(2) = 2 * f(2-1) + 1

f(2) = 2 * f(1) + 1

f(2) = 2(-3) + 1

f(2) = (-6) + 1

f(2) = -5

Which of the following polynomials corresponds to the subtraction of the multivariate polynomials 19x^3+44x^2y+17 and y^3-11xy^2
VARVARA [1.3K]
Name the two given polynomials as
f(x) = 19x³ + 44x²y + 17
g(x) = y³ - 11xy² + 2x²y - 13x³

Create the subtraction f(x) - g(x).
f(x)-g(x) = 19x³ + 44x²y + 17 - (y³ - 11xy² + 2x²y - 13x³)
             = (19 + 13)x³ + (44 - 2)x²y + 11xy² - y³ + 17
             = 32x³ - y³ + 42x²y + 11xy² + 17

Answer: D
Note that answer D has a typo. 11xy² is correct, but 11x²y is not.

Full Question

As a secondary mathematics teacher, Hernandez conducted a study that explored whether giving children recess prior to testing helped their test performance. For one of the semesters, he sends half of his classes out for 10 minutes of recess prior to testing for the other half, he provides 10 minutes of free time after the test. Which of the following best represents the design of Hernandez's study?

a. One-shot case study

b. Post-test only control group

c. Solomon four group

d. Static-group comparison

Answer:

Static-Group Comparison

Explanation:

A Static-Group Comparison describes a study that involves two non-randomly selected groups, where one groups receive the treatment, and the other does not before the test. Afterwards, a post-test examination of the score is then carried out to examine the different in performance between both groups.

Ex 4.8<br> 14) integrate 3^(2x-1)
sesenic [268]
Take the integral:

\large\begin{array}{l} \mathsf{\displaystyle\int\!3^{2x-1}\,dx}\\\\ =\mathsf{\displaystyle\int\!\frac{1}{2}\cdot 2\cdot 3^{2x-1}\,dx}\\\\ =\mathsf{\displaystyle\frac{1}{2}\int\!3^{2x-1}\cdot 2\,dx\qquad(i)} \end{array}


\large\begin{array}{l} \textsf{Substitute}\\\\ \mathsf{2x-1=u\quad\Rightarrow\quad 2\,dx=du}\\\\\\ \textsf{so (i) becomes}\\\\ =\mathsf{\displaystyle\frac{1}{2}\int\!3^u\,du}\\\\ =\mathsf{\dfrac{1}{2}\cdot \dfrac{1}{\ell n\,3}\,3^u+C}\\\\ =\mathsf{\dfrac{1}{2\,\ell n\,3}\,3^{2x-1}+C} \end{array}


\large\begin{array}{l} \boxed{\begin{array}{c}\mathsf{\displaystyle\int\!3^{2x-1}\,dx=\frac{1}{2\,\ell n\,3}\,3^{2x-1}+C} \end{array}}\qquad\checkmark \end{array}
