Without exponents logc (xy^6z^-4) what is the equivalent expression

Mathematics

Sever21 [200]2 years ago

By eliminating exponents, the <em>logarithmic</em> expression \log_{c} x\cdot y^{6}\cdot z^{-4} is equivalent to the <em>logarithmic</em> expression \log_{c} x + 6\cdot \log_{c} y - 4\cdot \log_{c} z.

<h3>How to simplify logarithmic functions</h3>

In this problem we are supposed to eliminate all exponents of a <em>logarithmic</em> function by applying any of the following properties:

  1. ㏒ x · y = ㏒ x + ㏒ y
  2. ㏒ x/y = ㏒ x - ㏒ y
  3. ㏒ yˣ = x · ㏒ y

Now, we proceed to simplify the function:

\log_{c} x\cdot y^{6}\cdot z^{-4}

\log_{c} x + \log_{c} y^{6} + \log_{c} z^{-4}

\log_{c} x + 6\cdot \log_{c} y - 4\cdot \log_{c} z

By eliminating exponents, the <em>logarithmic</em> expression \log_{c} x\cdot y^{6}\cdot z^{-4} is equivalent to the <em>logarithmic</em> expression \log_{c} x + 6\cdot \log_{c} y - 4\cdot \log_{c} z.

Show me how to graph f(x)=3/2 x + 2
Alexxx [7]

y = (3x)/2 + 2

Slope = 3/2

y-intercept = 2


The first point is y-intercept when x = 0 = (0,2). Now according to our slope we move 3 up (Why up? Because it's positive) and 2 right (Why right? Because it's positive).

When you move 3 up from (0,2), you get (0,5) and move 2 right which is (2,5).

Remember: slope = change in y / change in x


Points: (0,2) and (2,5)

According to a marketing research study, American teenagers watched 14.8 hours of social media posts per month last year, on ave
ki77a [65]

Answer:

The value of test statistics is 1.06.

Step-by-step explanation:

We are given that according to a marketing research study, American teenagers watched 14.8 hours of social media posts per month last year, on average. A random sample of 11 American teenagers was surveyed and the mean amount of time per month each teenager watched social media posts was 15.6. This data has a sample standard deviation of 2.5.

We have to test if the mean amount of time American teenagers watch social media posts per month is greater than the mean amount of time last year or not.

Let, NULL HYPOTHESIS, H_0 : \mu = 14.8 hours  {means that the mean amount of time American teenagers watch social media posts per month is same as the mean amount of time last year}

ALTERNATE HYPOTHESIS, H_1 : \mu > 14.8 hours  {means that the mean amount of time American teenagers watch social media posts per month is greater than the mean amount of time last year}

The test statistics that will be used here is One-sample t-test;

             T.S. = \frac{\bar X - \mu}{\frac{s}{\sqrt{n} } } ~ t_n_-_1

where, \bar X = sample mean amount of time per month each teenager watched social media posts = 15.6 hours

             s = sample standard deviation = 2.5 hours

             n = sample of teenagers = 11

So, <u>test statistics</u> =  \frac{15.6 - 14.8}{\frac{2.5}{\sqrt{11} } } ~ t_1_0

                            = 1.06

Hence, the value of test statistics is 1.06.

Write an inequality that represents the graph.
Anika [276]

Answer:

y - 2x - 1 = 0

Step-by-step explanation:

the slope is :

\tan( \alpha )  = 4  \div 2 = 2

at a pt on graph , when

x = 1 \\ y = 3 \\

therefore, coordinates are (1,3)

The equation is :

(y - 3) = slope \times (x - 1) \\ (y - 3) = 2 \times (x - 1) \\  y - 3 = 2x - 2 \\ y - 2x - 1 = 0
