Answer:

Given function:

g(x)=6\left(\dfrac{3}{2}\right)^x

To find each of the points, substitute the given values of x into the function:

x=-1 \implies g(-1)=6\left(\dfrac{3}{2}\right)^{-1}=4

x=0 \implies g(0)=6\left(\dfrac{3}{2}\right)^{0}=6

x=1 \implies g(1)=6\left(\dfrac{3}{2}\right)^{1}=9

x=2 \implies g(2)=6\left(\dfrac{3}{2}\right)^{2}=13.5

Therefore:

\large \begin{array}{| c | c | c | c | c |}\cline{1-5} x & -1 & 0 & 1 & 2 \\\cline{1-5} g(x) & 4 & 6 & 9 & 13.5 \\\cline{1-5} \end{array}

As the function is <u>exponential</u>, there is a horizontal asymptote at y=0.

Therefore, as x approaches -∞ the curve approaches y=0 but never crosses it.

So the end behaviors of the graph are:

  • \textsf{As }x \rightarrow - \infty, \:\:g(x) \rightarrow 0
  • \textsf{As }x \rightarrow \infty, \:\:g(x) \rightarrow \infty

Plot the points on the graph and draw a curve through them.

Given the matrices A and B shown below, solve for X in the equation -1/3X + 1/3A=B
defon

Answer:

X=[24,,-33]

Step-by-step explanation:

The given equation is :

-\frac{1}{3}X+\frac{1}{3}A=B

We multiply through by 3 to get:

X-A=-3B

Solve for x to get:

X=A-3B

The entries are: A=[-12 -3] B= [-12 10]

Let X=[a,b]

We substitute the entries to get:

[a,b]=[-12,-3]-3[-12,10]

We simplify the Right Hand Side to get:

[a,b]=[-12,-3]-[-36,30]

We simplify further to get:

[a,b]=[-12--36,-3-30]

This implies that:

[a,b]=[24,-33]

Hence, X=[24,-33]

A survey of 394 children given at a local elementary school showed that 150 like chocolate ice cream 175 like pistachio ice crea
Airida [17]

Answer:

e) 294 children

Step-by-step explanation:

Since there are 394 children in total and 169 do not like either ice-cream, the number of children who likes at least 1 ice cream is

394 - 169 = 225 children

Out of 225 children, 150 like pistachio icecream, some of them may like both. Therefore the number of children who likes ONLY chocolate icecream is

225 - 150 = 75 children

Similarly, out of 225 children, 175 like chocolate icecream, some of them may like both. Therefore the number of children who likes ONLY pitaschio icecream is

225 - 175 = 50 children

So the total number of children who like at most only 1 kind of ice cream is

75 + 50 + 169 = 294 children
