4. Match the table with the function that models the data.

Which of the following is an arithmetic sequence?

arsen [322]

Answer:

Here are a few lists of numbers:

3, 5, 7 ...

21, 16, 11, 6 ...

1, 2, 4, 8 ...

Step-by-step explanation:

Ordered lists of numbers like these are called sequences. Each number in a sequence is called a term.

3,3,3, comma 5,5,5, comma 7,...7,...7, comma, point, point, point

\uparrow↑\uparrow \uparrow↑\uparrow \uparrow↑\uparrow

\footnotesize 1^\text{st}\text{ term}1

st

term1, start superscript, start text, s, t, end text, end superscript, start text, space, t, e, r, m, end text \footnotesize 2^\text{nd}\text{ term}2

nd

term2, start superscript, start text, n, d, end text, end superscript, start text, space, t, e, r, m, end text \footnotesize 3^\text{rd}\text{ term}3

rd

term3, start superscript, start text, r, d, end text, end superscript, start text, space, t, e, r, m, end text

Sequences usually have patterns that allow us to predict what the next term might be.

For example, in the sequence 3, 5, 7 ..., you always add two to get the next term:

\footnotesize\maroonC{+2\,\Large\curvearrowright}+2↷start color #ed5fa6, plus, 2, \curvearrowright, end color #ed5fa6 \footnotesize\maroonC{+2\,\Large\curvearrowright}+2↷start color #ed5fa6, plus, 2, \curvearrowright, end color #ed5fa6

3,3,3, comma 5,5,5, comma 7,...7,...7, comma, point, point, point

1. According to the Center for Disease Control and Prevention, the breast cancer rate for women has decreased at 0.9% per year b

jeka94

Answer:

a. 199,389

b. b. From the part A, the question suggests a 0.9% yearly decrease which amounts to 199,389. This answer does not correspond to their recorded figure because the 0.9% decrease was just an average taken over the period. There could be years that the decrease was way smaller than the recorded average, thus using average may not be a good way for calculating population decrease over a period of time.

Step-by-step explanation:

a. Population in 2009 = 192,370

This means that in 2005 the population = 192,370 x 1.009 x 1.009 x 1.009 x 1.009 = 199,389

b. From the part A, the question suggests a 0.9% yearly decrease which amounts to 199,389. This answer does not correspond to their recorded figure because the 0.9% decrease was just an average taken over the period. There could be years that the decrease was way smaller than the recorded average, thus using average may not be a good way for calculating population decrease over a period of time.

The area of a rectangle is 128 ft.² if the link is twice the width what is the measure of the width of the rectangle

andrew-mc [135]

Let, the width = x
Then,Length = 2x

Now, Area = l * w
A = (2x)(x)
128 = 2x²
x² = 128/2
x = √64
x = 8

In short, Your Answer would be 8 Feet

Hope this helps!

What’s the missing number in sequence 127, 144, 48, 66, 33, ?

aniked [119]

The missing number in the sequence is 52.

<h3>What is the missing number in the sequence?</h3>

In order to determine the missing number, the pattern in the sequence has to be determined.

The difference between the second and first number is 144 - 127 = 17

The third number is 3 times smaller than the second number: 144 / 48 = 3

The difference between the fourth number and the third number is 66 - 48 = 18.

The fifth number is 2 times smaller than the fourth number: 66/33 = 2

Based on this sequence, the sixth number would be 19 more than the fifth number. 33 + 19 = 52
