Consider the sequence of numbers: 3/8, 3/4, 1 /18, 1 1/2, 1 7/8
Question:
Consider the sequence of numbers: [tex]\frac{3}{8}, \frac{3}{4}, 1\frac{1}{8}, 1\frac{1}{2}, 1\frac{7}{8}[/tex]
Which statement is a description of the sequence?
(A) The sequence is recursive, where each term is 1/4 greater than its preceding term.
(B) The sequence is recursive and can be represented by the function
f(n + 1) = f(n) + 3/8 .
(C) The sequence is arithmetic, where each pair of terms has a constant difference of 3/4 .
(D) The sequence is arithmetic and can be represented by the function
f(n + 1) = f(n)3/8.
Answer:
Option B:
The sequence is recursive and can be represented by the function
[tex]f(n + 1) = f(n) + \frac{3}{8} .[/tex]
Explanation:
A sequence of numbers are
[tex]\frac{3}{8}, \frac{3}{4}, 1\frac{1}{8}, 1\frac{1}{2}, 1\frac{7}{8}[/tex]
Let us first change mixed fraction into improper fraction.
[tex]\frac{3}{8}, \frac{3}{4}, \frac{9}{8}, \frac{3}{2}, \frac{15}{8}[/tex]
To find the pattern of the sequence.
To find the common difference between the sequence of numbers.
[tex]\frac{3}{4}-\frac{3}{8}=\frac{6}{8}-\frac{3}{8}= \frac{3}{8}[/tex]
[tex]\frac{9}{8}-\frac{3}{4}=\frac{9}{8}-\frac{6}{8}= \frac{3}{8}[/tex]
[tex]\frac{3}{2}-\frac{9}{8}=\frac{12}{8}-\frac{9}{8}= \frac{3}{8}[/tex]
[tex]\frac{15}{8}-\frac{3}{2}=\frac{15}{8}-\frac{12}{8}= \frac{3}{8}[/tex]
Therefore, the common difference of the sequence is 3.
That means each term is obtained by adding [tex]\frac{3}{8}[/tex] to the previous term.
Hence, the sequence is recursive and can be represented by the function [tex]f(n + 1) = f(n) + \frac{3}{8} .[/tex]

What is the addictive inverse of 6x
The additive inverse of 6x is -6x.
This is because 6x + (-6x) = 6x - 6x = 0
Answer:
-6x
Step-by-step explanation:
It's a little unclear from the question what you mean, but I assume you mean the 'additive inverse'. In terms of solving equations, this term typically means we just minus 6x. i.e - 6x.
However, if the question means find the inverse function of f(x) = 6x,
then this would be a different answer: in particular, the inverse function is the function that 'undoes' this, so it would be f-1(x) = x/6.

Find the value of f(-1) for the function below. F(x)= 2/3×3(3x+12)
To find the value of f(-1), substitute -1 into the given function and evaluate it to get 42.
Explanation:To find the value of f(-1) for the given function f(x) = (2/3) * 3(3x + 12), we substitute x = -1 into the function and evaluate it.
Plugging in x = -1, we have f(-1) = (2/3) * 3(3(-1) + 12).
Simplifying further, f(-1) = (2/3) * 3(9 + 12).
f(-1) = (2/3) * 3(21).
f(-1) = (2/3) * 63 = 42.

Describe the effect an increase in n, the number of payment periods, has on the monthly payment P in the formula P = P V times StartFraction i over 1 minus (1 + i) superscript negative n Baseline EndFraction a. An increase in n, the number of payment periods, will not change P, the monthly payment. b. An increase in n, the number of payment periods, will create an increase in P, the monthly payment. c. An increase in n, the number of payment periods, will create a decrease in P, the monthly payment. d. An increase in n, the number of payment periods, can increase or decrease P, the monthly payment, depending on the value of PV.
Answer:
Option b. An increase in n, the number of payment periods, will create an increase in P, the monthly payment.Explanation:
The monthly payment formula described is:
[tex]P=PV\frac{i}{1-(1+i)^{-n}}[/tex]
Where:
P = monthly paymentPV = present valuei = interest rate per monthn = number of periods.Mathematically, you can reason in the following way:
When n increases, the factor (1 +i)⁻ⁿ which is equal to the 1 / (1+ir)ⁿ decreases (because the denominator increases, the fraction increases).When (1 + i)⁻ⁿ increases, 1 - (1 + i)⁻ⁿ decreases.Since 1 - (1 + i)⁻ⁿ is in the denominator, when it decreases the fraction, which is equal to P, increases.Thus, it is proved that an increase in n, the number of payment periods, will create an increase in P, the monthly payment (option b).
The BEST description of the effect of an increase in n, the number of payment periods, on the monthly payment is c. An increase in n, the number of payment periods, will create a decrease in P, the monthly payment.
When the number of payment periods, n, increases, the monthly payment of the Liability will decrease instead of increasing, nor will it remain the same.
Thus, the BEST description of the effect of an increase in n, the number of payment periods, on the monthly payment is Option C.

Cost of each adult ticket = $6
Total spent = $96
Let,
x be the number of kids ticket

[tex]70.5 \div 8 = 8.8125[/tex]
Answer:
1.63
Step-by-step explanation:
first we find the average of the numbers listed...do this by adding up all the numbers, then dividing by how many numbers there are.
(5 + 7.5 + 8.25 + 8 + 9.75 + 10.25 + 11 + 10.75) / 8 = 70.5 / 8 = 8.8125
now find the distance between the average and each of ur numbers.... IGNORE ALL NEGATIVE SIGNS
5 - 8.8125 = 3.8125
7.5 - 8.8125 = 1.3125
8.25 - 8.8125 = 0.5625
8 - 8.8125 = 0.8125
9.75 - 8.8125 = 0.9375
10.25 - 8.8125 = 1.4375
11 - 8.8125 = 2.1875
10.75 - 8.8125 = 1.9375
now take the average of those numbers
(3.8125 + 1.3125 + 0.5625 + 0.8125 + 0.9375 + 1.4375 + 2.1875 + 1.9375) / 8 =

A president and vice president for a sorority are chosen from ten people. How many different president/vice president combinations are possible?
Answer:
There are 90 ways.
Step-by-step explanation:
We have ten people and we have to chose 2 of those people to be the president and vice president. So first we can chose a president, we have 10 choices for president as there are 10 people.
Now we can chose vice president but this time we only have 9 choices because we already chose a president which gives us 9 other people to chose who the vice president is.
Now we need to multiply 10 and 9 together which gives us the total amount of possible combinations for president and vice president if there are 10 people to chose from.
10*9 multiplying
= 90.
Therefore there are 90 ways for a president and a vice president to be chosen for a sorority from ten people.
The total number of different combinations for the president and vice-president roles from a group of ten people is 90, based on the concept of permutation in combinatorics. After choosing one president among the ten people, there would be nine people left to be chosen for the vice-president position.
Explanation:This problem is about choosing two different roles (president and vice president) from a group of 10 people, with each person having a chance to occupy each role. This falls under the domain of combinatorics, a branch of mathematics dealing with combinations of objects belonging to a finite set following certain rules. We would need to use the concept of permutation in this instance. Permutations refer to the arrangement of items in a specific order.
Since all the 10 people could potentially be president, there are ten choices for the president. And after choosing a president, we would have left nine people. Among these, anyone could be vice-president, giving us nine choices for the vice-president. Hence, the total number of ways is equal to the product of the number of choices for the president and the vice-president, which is 10×9= 90.
Thus, there are 90 different combinations for the president and vice- president roles.

Simplify (5+6i)-(3-8i)-(5-3i)
Answer:
I think the answer is −3+17i
Step-by-step explanation:
:)
The simplified expression is 2 + 17i.
To simplify the expression (5+6i)-(3-8i)-(5-3i), we need to combine like terms.
Like terms are terms that have the same combination of real and imaginary parts.
When subtracting Simplifying complex numbers, we subtract the real parts and the imaginary parts separately.
In this case, the real parts are (5-3) = 2, and the imaginary parts are (6-(-8)-3) = 17.
Therefore, the simplified expression is 2 + 17i.

Complete the equation of the line whose slope is 5 and y intercept is (0,4)
y = 5x + 4 is the equation of the line whose slope is 5 and y intercept is (0,4)
Solution:
Given that, we have to write the equation of the line whose slope is 5 and y intercept is (0,4)
The equation of line in slope intercept form is given as:
y = mx + c ---- eqn 1
Where, "m" is the slope of line and "c" is the y - intercept
Given that, slope = m = 5
y intercept is (0, 4)
So, c = 4
Substitute c = 4 and m = 5 in eqn 1
y = 5x + 4
Thus the equation of line is found
