Step-by-step explanation:

1/7 + 7/11 <em>+ 2010/2011</em> + 6/7 + 4/11 <em>- 2010/2011</em>

= 1/7 + 6/7 + 7/11 + 4/11

= 7/7 +11/11

= 1 + 1

= 2

F(r) = -(1 – 12)(r + 3)<br> What are the zeros of the function

nexus9112 [7]

Answer:

r = -3

Step-by-step explanation:

The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.

What sequence is modeled by the graph below?

Lady bird [3.3K]

ANSWER

$a_n= \frac{1}{2}( {2}^{n - 1} )$

EXPLANATION

The corresponding ordered pairs from the graph are:

(2,1) (3,2) (4,4) (5,8)

The y-values are:

1,2,4,8

The first term term is the term before 1,this has to be.

$a_1= \frac{1}{2}$

The common ratio is

$r = \frac{2}{1} = 2$

The nth term is given by

$a_n=a_1 {(r}^{n - 1} )$

Let's substitute the values to get,

$a_n= \frac{1}{2} \times {(2}^{n - 1} )$

This simplifies to,

$a_n= \frac{1}{2} {(2}^{n - 1} )$

The n number of homeruns hit during the regular season by a certain baseball player can be modeled by the function n(x) =3/4x, w

sukhopar [10]

Answer:

The average rate of change is equal to $\frac{3}{4}\frac{homeruns}{game}$

Step-by-step explanation:

we have

$n(x)=\frac{3}{4}x$ -----> this is a linear direct variation

we know that

The rate of change of a linear variation is a constant

The rate of change of a linear variation is equal to the slope of the line

In this problem the slope of the line is equal to $m=\frac{3}{4}\frac{homeruns}{game}$

therefore

The average rate of change is equal to $\frac{3}{4}\frac{homeruns}{game}$

<u>Verify</u>

the average rate of change is equal to

$\frac{n(b)-n(a)}{b-a}$

In this problem we have

$n(a)=n(12)=\frac{3}{4}(12)=9\ homeruns$

$n(b)=n(60)=\frac{3}{4}(60)=45\ homeruns$

$a=12\ games$

$b=60\ games$

Substitute

$\frac{45-9}{60-12}=\frac{3}{4}\frac{homeruns}{game}$
