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?
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
Solve the equation 4.1g+6=2.1g+12.
a. Find the value of g.
b. Explain how you can check that the value you found for g is correct. If your check does not work, does that mean that your result is incorrect? Explain.
a. g=
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.

Step-by-step explanation:
suppose you are buying two kinds of chips for a party. Each bag of potato chips cost $2.50 and each bag of corn chips cost $2.90. You must have at least 100 bags of chips for the party and the total cost of the chips can be no more than $350
Part A:Write a system of two inequalities that describe the situation
Part B: Write one possible solution to the problem in sentence form
Answer:
At least means ≥
No more than means ≤
Let x = number of bags of potato chips
Let y = the number of bags of corn chips
x+y≥100
2.50x+2.90y≤$350
Let's try x=80 and y=20 (We know that is equals 100 so it will work for the first equation
2.50(80)+2.90(20) = 258 which is ≤$350
Buy 80 bags of potato chips and 20 bags of corn chips is one possibility.
The perimeter of a kite can be found using the formula P = 2S + 2L. Which equation expresses S in terms of P and L?
Answer:
Step-by-step explanation:
P = 2S + 2L
2S + 2L = P
2S = P - 2L
S = [tex]\frac{P-2L}{2}[/tex]
Answer:
0.5P - L
Step-by-step explanation:
P = 2S + 2L
P - 2L = 2S +2L - 2L
P - 2L = 2S
0.5P - L = S
What is the measure of each angle of a regular pentagon?
Plz help
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

Johanna can type 120 words in 3 minutes. Using the same unit rate, how many words can
she type in 10 minutes?
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!
