Hi there!

You are partially correct on the π symbol, but there's more!

The formula for finding the area of a circle is:

A = π r².

A stands for area, π stands for pi, and r stands for radius. The ² is there because the radius is half as big as the diameter of a circle.

Hope this helps! :D

And remember, you can message me whenever you need to on anything you may need help with!

Which is the graph of a logarithmic function?

Reika [66]

The domain and range of the graph of a logarithmic function are;

Domain; 0 < x < +∞

Range; The set of real numbers.

<h3>How can the graph that correctly represents a logarithmic function be selected?</h3>

The basic equation of a logarithmic function can be presented in the form;

$y = log_{b}(x)$

Where;

b > 0, and b ≠ 1, given that we have;

$y = log_{1}(x)$

${1}^{y} = 1$

The inverse of the logarithmic function is the exponential function presented as follows;

$x = {b}^{y}$

Given that <em>b</em> > 0, we have;

${b}^{y} = x > 0$

Therefore, the graph of a logarithmic function has only positive x-values

The graph of a logarithmic function is one with a domain and range defined as follows;

Domain; 0 < x < +∞

Range; -∞ < y < +∞, which is the set of real numbers.

The correct option therefore has a domain as <em>x </em>> 0 and range as the set of all real numbers.

Factor x2 – 6x – 7.

SpyIntel [72]

You can make an cb chart. so to equal -6 you need the numbers -7, 1. so now the equation is ( x - 7 )( x + 1 ). if you want to solve it set it equal to 0 and solve.

Decrease 1.25 km by 0.6%

Anna35 [415]

Answer:

124250cm, 1242.5m or 1.2425km

Step-by-step explanation:

0.6% = 6/100

6/100 = 0.006

0.006*1.25 = 0.0075

1.25km = 1250m = 125000cm

0.0075km = 7.5m = 750cm

125000 - 750 = 124250

Therefore:

The answer is 124250cm, 1242.5m or 1.2425km

Pen are shipped to the office supply store in boxes of 12 each. Write a function rule to calculate the total number of pens when

Tom [10]

p = 12x is the function rule to calculate the total number of pens when you know the number of boxes

<em><u>Solution:</u></em>

Given that,

Pen are shipped to the office supply store in boxes of 12 each

To find: Write a function rule to calculate the total number of pens when you know the number of boxes

Let "p" be the total number of pens

Let "x" be the number of boxes

Number of pens in each box = 12

Then from given information,

Total number of pens = Number of boxes multiplied by number of pens in each box

$p = x \times 12\\\\p = 12x$

Thus the function rule is found
