A sequence can be generated by using fn = 2f(n-1)+1, where f1 = 4 and n is a whole number greater than 1. What are the first four terms in the sequence?
Answers
Answer:
{9,19,39,79}
Step-by-step explanation:
Recursive Sequences
The recursive sequence can be identified because each term is given as a function of one or more of the previous terms. Being n an integer greater than 1, then:
f(n) = 2f(n-1)+1
f(1) = 4
To find the first four terms of the sequence, we set n to the values {2,3,4,5}
For n=2f(2) = 2f(1)+1
Since f(1)=4:
f(2) = 2*4+1
f(2) = 9
For n=3f(3) = 2f(2)+1
Since f(2)=9:
f(3) = 2*9+1
f(3) = 19
For n=4f(4) = 2f(3)+1
Since f(3)=19:
f(4) = 2*19+1
f(4) = 39
For n=5f(5) = 2f(4)+1
Since f(4)=39:
f(5) = 2*39+1
f(5) = 79
What is the measure of each angle of a regular pentagon?
Plz help
Answers
Answer:
108 deg
Step-by-step explanation:
The sum of the measures of the interior angles of a polygon with n sides is
(n - 2)180.
The measure of each angle of a regular polygon with n sides in
[(n - 2)180]/n.
In this case, n is 5 for a pentagon.
[(n - 2)180]/n = [(5 - 2)180]/5 = [(3)180]/5 = 540/5 = 108

Step-by-step explanation:
P = 2S + 2L
2S + 2L = P
2S = P - 2L
S = [tex]\frac{P-2L}{2}[/tex]
Answer:
0.5P - L

P = 2S + 2L
P - 2L = 2S +2L - 2L
P - 2L = 2S

Johanna can type 120 words in 3 minutes. Using the same unit rate, how many words can
she type in 10 minutes?
Answers
Answer:
600 words.
Step-by-step explanation:
If Johanna can type 120 words in 3 minutes, and the problem is asking us to find how many words she can type in 10 minutes at the same unit rate, we'll have to start by solving how many words she can type in 1 minute:
[tex]\frac{120}{3}[/tex]
Dividing 120 words into 3:
[tex]=60[/tex] words per minute.
Now that we know how many words Johanna types in one minute (per minute), we can multiply the words per minute by 10 (minutes):
[tex]60[/tex] × [tex]10=600[/tex] words in 10 minutes.
_
We can check our work by dividing 600 words into 10 minutes to see if we achieve the same unit rate of 60 words per minute:
[tex]\frac{600}{10}[/tex]
[tex]=60[/tex] words per minute.
Since we have the same unit rate, our answer is correct!

A pretzel manufacturer has two production lines. Line A produces a variety of pretzel that is sold for $2.40 per bag. Line A typically produces 3 bags per day that do not meet company standards and cannot be sold. Line B produces a variety of pretzel that is sold for $3.60 per bag. Line B typically produces 4 bags per day that do not meet company standards and cannot be sold. Line A produces 3 times as many bags as Line B each day. Write a linear function that represents the total number of bags the lines can produce combined.

Answer:
f(x)=19x - 7x
Step-by-step explanation:
I am a high schooler as well and was working on this problem as well. I can't say I'm right or wrong because I didn't have a grade on it yet. I believe the answer is f(x)=19x - 7x. The Lines don't have a given value, so I chose the values 12 for Line A and 7 for Line B. I believe the answer is this because Line A would produce 12 bags each day and 3 of them would not be useable, leaving you with 9. Line B would produce 7 and 4 of them would be unusable, leaving you with 3. Line A produces 9 per day while Line B produces 3, and that would check off the part that says, "Line A produces 3 times as many bags as Line B each day." Throughout the problem, it talks about how many bags can each line produces each day, and the sentence talks about that specifically as well. So, the function must be about the amount of bags produced per day. x would represent the number of days that the Lines have been working. 19 is the total amount of bags that was produced in a day. 7 represents the total amount of bags that are unusable. Though I may be wrong, I hope this might help you come to a conculsion of your own.

a. g=
Answers
Answer:
g=3
Step-by-step explanation:
The value of g is 3 and it is correct when checked by substituting g=3 into the equation.
Given:
4.1g + 6 = 2.1g + 12
collect like terms
4.1g - 2.1g = 12 - 6
2g = 6
divide both sides by 2
g = 6 / 2
g = 3
Check:
4.1g + 6 = 2.1g + 12
4.1(3) + 6 = 2.1(3) + 12
12.3 + 6 = 6.3 + 12
18.3 = 18.3
Therefore,
The value of g is 3 and it is correct when checked by substituting g=3 into the equation.
