The table represents an exponential function.

kkurt [141]

Answer:

b=2/3

Step-by-step explanation:

The table is given as:

$\left|\begin{array}{c|c}x&y\\--&--\\1&9\\2&6\\3&4\\4&\dfrac83\\\\5&\dfrac{16}{9}\end{array}\right|$

The exponential function is given in the form

$y= a (b)^{x}$

where a is the initial value and b is the multiplicative rate of change

When x=1, y=9, we have:

$9= a (b)^{1}$

When x=3, y=4, we have:

$4= a (b)^{3}$

Dividing the two equations:

$\dfrac{a (b)^{3}}{a (b)^{1}} =\dfrac{4}{9} \\b^2=\dfrac{4}{9}\\b=\sqrt{\dfrac{4}{9}} \\b=\dfrac{2}{3}$

The multiplicative rate of change, b is 2/3.

What is the product of 7/8×1/2

Gelneren [198K]

$\frac{7}{8} \times \frac{1}{2}$

$= \frac{7 \times 4}{8}$

$= \frac{28}{8}$

$= \frac{ \cancel{28}}{ \cancel{8}}$

$= \frac{14}{4}$

$= \frac{ \cancel{14}}{ \cancel{4}} = \frac{7}{2}$

<h2>The required answer is 7/2 </h2>

What are the solution(s) for the quadratic equation?

MariettaO [177]

Let's see

$\\ \rm\rightarrowtail x^2+12x+36=0$

$\\ \rm\rightarrowtail x^2+6x+6x+36=0$

$\\ \rm\rightarrowtail x(x+6)+6(x+6)=0$

$\\ \rm\rightarrowtail (x+6)(x+6)=0$

$\\ \rm\rightarrowtail x=-6$
