Find the increasing functions. Then arrange the increasing functions in order from least to greatest rate of change. (not all of

Aleksandr [31]

Answer:

to a function is increasing we have to find the slope of the function

the higher the slope the faster the growth

Step-by-step explanation:

slope = 5/2. which is 2.5
slope 2 = -1/2 which is -0.5
slope 3 = 3/2 which is 1.5
slope 4 = 1/2 which is 0.5
slope 5= 4/3 which is 1.33
slope 6 = 3/4 which is 0.75

so the function in increasing order

y= -1/2x + 1/2

y= 1/2x - 2

y=3/4x - 10

y=4/3x -7/3

y=3/2x-11/2

y=5/2x +10

How is the series 5+11+17…+251 represented in summation notation?

NISA [10]

Answer:

$\displaystyle \large{\sum_{n=1}^{42}(6n-1)$

Step-by-step explanation:

Given:

Series 5+11+17+...+251

To find:

Summation notation of the given series

Summation Notation:

$\displaystyle \large{\sum_{k=1}^n a_k}$

Where n is the number of terms and $\displaystyle \large{a_k}$ is general term.

First, determine what kind of series it is, there are two main series that everyone should know:

Arithmetic Series

A series that has common difference.

Geometric Series

A series that has common ratio.

If you notice and keep subtracting the next term with previous term:

11-5 = 6
17-11 = 6

Two common difference, we can in fact say that the series is arithmetic one. Since we know the type of series, we have to find the number of terms.

Now that brings us to arithmetic sequence, we know that first term is 5 and last term is 251, we’ll be finding both general term and number of term using arithmetic sequence:

<u>Arithmetic Sequence</u>

$\displaystyle \large{a_n=a_1+(n-1)d}$

Where $\displaystyle \large{a_n}$ is the nth term, $\displaystyle \large{a_1}$ is the first term and $\displaystyle \large{d}$ is the common difference:

So for our general term:

$\displaystyle \large{a_n=5+(n-1)6}\\\displaystyle \large{a_n=5+6n-6}\\\displaystyle \large{a_n=6n-1}$

And for number of terms, substitute $\displaystyle \large{a_n}$ = 251 and solve for n:

$\displaystyle \large{251=6n-1}\\\displaystyle \large{252=6n}\\\displaystyle \large{n=42}$

Now we can convert the series to summation notation as given the formula above, substitute as we get:

$\displaystyle \large{\sum_{n=1}^{42}(6n-1)$

Which of the following functions has an inverse that is not a function?

hichkok12 [17]

<h2><u>Answer:</u></h2><h2>y=x^2 has an inverse but it is not a function</h2><h2><u>Step-by-step explanation:</u></h2><h2>y = x</h2><h2>y=x has an inverse function. y=x is the equation of a line. All line has an inverse function and it is also a function</h2><h2>y = 2x + 1 is the equation of a line.</h2><h2>All line has an inverse function and it is also a function</h2><h2>y = x^2 is the equation of a quadratic Quadratic equation has an inverse but it does not pass vertical line test.Hence it is not a function</h2><h2><u></u></h2><h2><u>Thank you</u></h2><h2><u>sunshinemadison101</u></h2>

When 9 Superscript two-thirds is written in simplest radical form, which value remains under the radical?

salantis [7]

Answer:

Step-by-step explanation:

$9^{\frac{2}{3}}=(3^2)^{\frac{2}{3}}=3^{\frac{4}{3}}=3\cdot 3^{\frac{1}{3}}\\\\=3\sqrt[3]{3}$

The table below shows the results of flipping two coins. how does the experimental probability of getting HH compare to the theo

marusya05 [52]

The correct answer is option B. i.e. the experimental probability is 3% greater than the theoretical probability<span>

The </span>theoretical Outcomes are: HH HT TH TT
Then, the probability of getting HH = 1/4 = 0.25 = 25%

Now, Experimental Outcomes : <span>HH=28 HT=22 TH=34 TT=16
Total number of outcomes = 28+22+34+16 = 100
</span>Then, the probability of getting HH = 28/100 = 0.28 = 28%

Thus, <span>the experimental probability is 3% greater than the theoretical probability</span>
