Enter the first 4 terms of the sequence defined by the given rule. Assume that the domain of each function is the set of whole numbers greater than 0.
[tex]f(n) =3 {n}^{2} + 1[/tex]
Given:
The rule for the sequence is
[tex]f(n)=3n^2+1[/tex]
Domain of the function is the set of whole numbers greater than 0.
To find:
The first 4 terms of the sequence defined by the given rule.
Solution:
We have,
[tex]f(n)=3n^2+1[/tex]
Domain of the function is the set of whole numbers greater than 0. So, domain for first four terms are 1, 2, 3 and 4 respectively.
For n=1,
[tex]f(1)=3(1)^2+1[/tex]
[tex]f(1)=3(1)+1[/tex]
[tex]f(1)=3+1[/tex]
[tex]f(1)=4[/tex]
For n=2,
[tex]f(2)=3(2)^2+1[/tex]
[tex]f(2)=3(4)+1[/tex]
[tex]f(2)=12+1[/tex]
[tex]f(2)=13[/tex]
For n=3,
[tex]f(3)=3(3)^2+1[/tex]
[tex]f(3)=3(9)+1[/tex]
[tex]f(3)=27+1[/tex]
[tex]f(3)=28[/tex]
For n=4,
[tex]f(4)=3(4)^2+1[/tex]
[tex]f(4)=3(16)+1[/tex]
[tex]f(4)=48+1[/tex]
[tex]f(4)=49[/tex]
Therefore, the first 4 terms of the sequence defined by the given rule are 4, 13, 28 and 49 respectively.

You spend 15 minutes . You then spend two hours reading email. Write the ratio of the amount of time spent watching television to the amount of time spent reading email as a fraction in simplest form.
Answer:
1:8
Step-by-step explanation:
The ratio for watching tv, to reading email is 15:120 (because two hours equals 120 min.).I then divided both sides by three to get 5:40. I then divided that ratio by 5 to get 1:8, which is the simplest form.

what is the slope intercept equation of this line
Answer:
B
Step-by-step explanation:
One approach is to plug (2, -2) to every function and only B will work.
Choice A) y = 3x + 4
-2 = 3(2) + 4
-2 = 10
Does not work
Choice B) y = -3x + 4
-2 = -3(2) + 4
-2 = -2
Works
Choice C) y = -1/3x + 4
-2 = -1/3(2) + 4
-2 = -2/3 + 4
-2 = -2/3 + 12/3
-2 = 10/3
Does not work
Choice A) y = 4x - 3
-2 = 4(2) - 3
-2 = 5
Does not work
You can also just take a look at the function and see that its slope is downwards so it has to be negative. Then check the slope using rise/run.
For every 1 to the right it goes down 3, so -3/1 = -3. The only function with a slope of -3 is answer choice B.

total yarn = red yarn + blue yard
= 4 in + 2 in
= 6 in
The perimeter of a trianglular pool is 36
yards the length of two sides or 10 yards and 15 yards how long is the third side
Answer:
11 yard
Step-by-step explanation:
Let the 3rd side be 'a'.
Perimeter = 36
=> sum of sides = 36
=> 10 + 15 + a = 36
=> 25 + a = 36
=> a = 36 - 25
=> a = 11
The ratio of yes votes to no votes was 4 to 7. If there were 3824 yes votes, what was the total number of votes?
Answer:
10,516
Step-by-step explanation:
you can do it different ways but I found the scale factor by dividing 4 into 7 which gives you 1.75 you then multiply that by the amount of yes votes (3824x1.75) which gives you 6692 and then you add that to the amount of yes votes which gives you the answer, 10516 - the total number of votes!
Divide total yes votes by the ratio for yes then multiply by the ratio for no:
3824 /4 = 956
956 x 7 = 6692 total number of no votes
total number of votes = 6692 + 3824 = 10,516
m TMN = x + 72, m LMN = 166°, and m LMT = 96 + x. Find m LMT. what is the answer to this? ill make you the brainly
Answer: LMT=95
Step-by-step explanation:
combine both problems to equal 166
x+x+72+96=166
Combine like terms
2x+168=166
Subtract 168 from 166
2x=168-166
Divide
X=-2/2
X=-1
Plug in -1 for x
96-1=95
72-1=71
71+95=166
LMT=95
9325 cm is equal to how many meters?
Answer:
93.25
Step-by-step explanation:
One meter = 100 cm
9300 divided by 100 = 93 + 0.25 = 93.25
The conversion of the given measurement of 9325 cm to meters is gotten as; 93.25 meters
How to convert Centimeter to meter?There are different units in mathematics to convert. However, in this case, we want to convert centimeters to meters.
Now, the conversion rate here is;
100cm = 1m
Thus, to convert 9325 cm to meters we will just divide it by 100.
Thus;
9325 cm = 9325/100 = 93.25 meters

Thom’s restaurant bill is $45 and he leaves a 20 percent tip. What is the total cost for Thom’s meal?
$20
$54
$65
$90
Answer:
$54
Step-by-step explanation:
[tex]\frac{x}{45} = \frac{20}{100}[/tex]
To get x which is the 20% tip
1. 45×20 = 900
2. 900÷100=9
3. 9 is the tip
To get the total cost, you would have to add $9 to $45 which is $54.

Answer:
B
Step-by-step explanation:
The question can be written is
5^x = 75
Now take the log of both sides.
log(5x) = log(75) Bring the x outside the brackets
x log(5) = log(75) Divide by log 5
x = log(75)/log(5)
log 75 = 1.8751
log 5 = .8990
x = 1.8751/.8990 = 2.6826
Answer:
(b) 2.68
Step-by-step explanation:
Your question has a link to a suitable calculator. All you need to do is make use of it. It tells you log₅(75) ≈ 2.68.
__
Other ways to look at the problem
If you recall that a logarithm represents an exponent of the base, you can ask yourself, what power 5 must be raised to in order to get 75. You know that 5^2 = 25, and 5^3 = 125, so the power will have to be between 2 and 3. There is only one answer choice in that range: 2.68.
__
The rules of logarithms let you rewrite the given expression as ...
log₅(75) = log₅(3×5²) = log₅(3) +2·log₅(5) = log₅(3) +2
The log₅ of any number between 1 and 5 will be a positive fraction, so this sum must be between 2 and 3.

Vertical angles measure (x-28) degrees and (0.5x-13) degrees. What is the value of x?
Answer:
x = -30
Step-by-step explanation:
Ok remember this because its important vertical angles means the two angles are congruent and congruent means when two things are the same
if those two angles are vertical angles what does that mean?
They both equal each other because they are the CONGRUENT!
x-28 = 0.5x -13
combine like terms so add 28 to both sides
x = 0.5x + 15
then subtract - 0.5x on both sides
- 0.5x = 15
then get x by itself by dividing - 0.5 on both sides
x = -30
