Vlad1618 [11]

to be sure that 2 of them will be blue i have to select 7+2=9 balls
7+8=15 balls in the urn
P=9/15

to be sure that 4 of them will be yellow i have to select 8+4=12 balls
P=12/15

The graphs of f(x) and g(x) are shown below: graph of function f of x open upward and has its vertex at negative 7, 0. Graph of

dexar [7]

The equation of the function is g(x)=(x+7)² -2 , Option D is the correct answer.

<h3>What is a Function ?</h3>

A function is a mathematical statement that defines relation between two variables.

The f(x) = (x+7)²

The equation for g(x) is ?

graph of function f of x open upward and has its vertex at (-7,0).

Graph of function g of x opens upward and has its vertex at (-7,2).

g(x) is formed by the translation of the function f(x) such that it's vertex is (-7,-2)

Therefore the equation of the function is

g(x)=(x+7)² -2

Therefore , the translation is a shift of the function f(x) 2 units down

Option D is the correct answer.

What is the decay factor of the exponential function<br> represented by the table?

bulgar [2K]

Given:

The table of values of an exponential function.

To find:

The decay factor of the exponential function.

Solution:

The general form of an exponential function is:

$y=ab^x$ ...(i)

Where, a is the initial value and $0$ is the decay factor and $b>1$ is the growth factor.

The exponential function passes through the point (0,6). Substituting $x=0,y=6$ in (i), we get

$6=ab^0$

$6=a(1)$

$6=a$

The exponential function passes through the point (1,2). Substituting $x=1,y=2,a=6$ in (i), we get

$2=6(b)^1$

$2=6b$

$\dfrac{2}{6}=b$

$\dfrac{1}{3}=b$

Here, $b=\dfrac{1}{3}$ lies between 0 and 1. Therefore, the decay factor of the given exponential function is $\dfrac{1}{3}$ .

Hence, the correct option is A.
