Answer:

<u>Parent function</u>

f(x)=\log_2(x)

Since we cannot take logs of zero or negative numbers, the domain is (0, \infty) and there is a vertical asymptote at x=0.

There are no horizontal asymptotes and the range is (- \infty,\infty).

The end behaviors of the parent function are:

\textsf{As } x \rightarrow 0^+, f(x) \rightarrow - \infty

\textsf{As } x \rightarrow \infty, f(x) \rightarrow \infty

To determine the attributes of the given function, compare the given function with the parent function.

<u>Given function</u>

<u />f(x)=- \log_2(x)+5

The given function is <u>reflected in the x-axis</u>.  Therefore, the end behaviors are a reflection of those of the parent function:

\textsf{As } x \rightarrow 0^+, f(x) \rightarrow \infty

\textsf{As } x \rightarrow \infty, f(x) \rightarrow - \infty

As the given function is <u>translated vertically</u> (5 units up) only, the domain, range and asymptote will not change, since the function has not been translated horizontally.

\textsf{Domain}: \quad (0, \infty)

\textsf{Range}: \quad (- \infty, \infty)

\textsf{Asymptote}: \quad x=0

<u>Conclusion</u>

The function f(x) is a \boxed{\sf logarithmic}} function with a \boxed{\sf vertical}} asymptote of \boxed{x = 0}.  

The range of the function is \boxed{(- \infty, \infty)}, and it is \boxed{\sf decreasing} on its domain of \boxed{(0, \infty)}.  

The end behavior on the LEFT side is as \boxed{x \rightarrow 0^+}, \boxed{f(x) \rightarrow \infty}, and the end behavior of the RIGHT side is \boxed{x \rightarrow \infty}, \boxed{f(x) \rightarrow -\infty}.

The least-squares regression line is ________.
Murljashka [212]

Answer:

a. the line that passes through the most data points.

Step-by-step explanation:

Regression analysis, is used to draw the line of‘ best fit’ through co-ordinates on a graph. The techniques used enable a mathematical equation of the straight line form y=mx+c to be deduced for a given set of co-ordinate values, the line being such that the sum of the deviations of the co-ordinate values from the line is a minimum, i.e.

The least-squares regression lines  is the line of best fit

The hypotenuse of a right triangle measures 16 cm and one of its legs measures 9 cm. Find the measure of the other leg. If neces
Vesnalui [34]

\sf\huge\underline{\star Solution:-}

<h3><u>Given that</u>:</h3>
  • Hypotenuse of a right triangle = \sf\blue{16cm.}
  • One side (leg) = \sf\blue{9cm.}

<h3><u>To Find</u>:</h3>
  • Measure of another side(leg).

<h3><u>Solution</u>:-</h3>

\rightarrow As we know that,

\sf{A^2 +B^2 \:=\: C^2}(Pythagoras Theorem)

So, using this formula we can find measure of another side(leg).

\rightarrow\sf{A^2 +B^2 \:=\: C^2}(putting the value of both given side of triangle)

  • Here I am putting the value of hypotenuse in C because it is the longest side of triangle.

\rightarrow \sf{9^2 +B^2 \:=\: 16^2}

\rightarrow \sf{81 +B^2 \:=\: 256}

\rightarrow \sf{B^2 \:=\: 256-81}

\rightarrow \sf{B^2 \:=\: 175}

\rightarrow \sf{B \:=\: \sqrt{175}}

\rightarrow \sf{B\:=\: 13.22(approx)}

Therefore, measure of another side (leg) of the triangle = \sf\purple{ 13.22(approx).}
