The sequence defines a function f(x)=4.(3)^{x-1}

Domain : \{1,2,3,4,5\}

Range : \{4,12,36,108,324\}

Explanation:

A sequence defines a function if it is the set of natural numbers.

Thus, the function is given by

f(x)=4.(3)^{x-1}

The sequence can be determined by substituting the values for x.

For x=1,

f(1)=4(3)^{0}=4

For x=2,

f(2)=4(3)^{1}=4(3)=12

For x=3,

f(3)=4(3)^{2}=4(9)=36

For x=4,

f(4)=4(3)^{3}=4(27)=108

For x=5,

f(5)=4(3)^{4}=4(81)=324

Thus, from these the domain and range of a function can be determined.

The domain of a function is the set of independent values, which are generally the x-coordinates.

Domain of a function is \{1,2,3,4,5\}

The range of a function is the set of dependent values obtained by substituting the values for x.

Range of a function is \{4,12,36,108,324\}

Find the truth value in each statement (true or false). 1.) C, E, and D are coplanar. 2.) B and E are collinear.
MaRussiya [10]
You need to post the diagram that goes to this question. But here's a hint so you can do this on your own co planar means that the points are in the same plane and collinear means that the points are on the same line.

Step-by-step explanation:

5-1/2-3

5-1 ( 4)

2-3 (-1)

y=-4/1x+b

5=-4/1(2)+b

5=-8+b

b=-13

Karla had $138.72 in her checking account. She wrote checks for $45.23 and $18. Then she made a deposit for 75.85 into her accou
vampirchik [111]

Answer:

$151.34

Step-by-step explanation:

First, Karla starts with $138.72.

Then Karla writes checks for $45.23 and $18.00. This means the money will be withdrawn, so let's subtract these from the total.

$138.72 - $45.23 - $18.00 = $75.49

Now, Karla has $75.49 in her account.

However, a $75.85 deposit is made to her account. So let's add this back to the total.

$75.49 + $75.85 = $151.34

So after all the transactions, Karla has $151.34 in her checking account.
