The common ratio for the given sequence is -2.
Any term in the provided geometric sequence can be divided by the term before it to determine the common ratio.
For instance, the ratio obtained by dividing 22 by -11 is 2, the ratio obtained by dividing 88 by 22 is 4, and so on. This approach allows us to determine that the general ratio is -2. This indicates that the previous term is multiplied by -2 to produce each word in the sequence.To put it another way, the sequence begins with -11, and each term after that is acquired by multiplying the previous term by -2. Therefore, -11 x (-2) = 22 would be the following number, followed by 22 x (-2) = -44, and so on.So the common ratio of the given sequence is -2.

Determine if the sequence below is arithmetic or geometric and determine the
common difference / ratio in simplest form.
14, 10, 6, ...
Answer:
Step-by-step explanation:
Each term in the sequence is 4 less than the previous term. That indicates an arithmetic sequence, which has the form a(n) = a(1) + d(n -1), where d is the common difference. Here the common difference is -4, and so the appropriate sequence is
a(n) = 14 - 4(n - 1)
What is a formula for the nth term of the given sequence? 15,75,375
Answer:
3 × 5 ^ n
Step-by-step explanation:
since the series is exponential, the ratio between adjacent terms is 5.
nth term of geometric/exponential series is given by:
nth term = first term × (ratio)^(n-1)
= 15 × 5^ (n-1)
= 15 × 5^n × 5^-1
= 3× 5^n
Chanise's allowance is 1 3 of her older brother's allowance. Chanise's allowance is $6 per week. Solve the equation a 3 =6 to find out how much allowance Chanise's brother earns in a week.
Answer:
a = $ 18
Step-by-step explanation:
It is given that Chinase's allowance is $6 per week and it is 1/3rd of his brother's allowance. Assuming the brother's allowance as "a", we can write the equation as follows:
[tex]\$6 = \frac{a}{3}\\a = (\$6)(3)[/tex]
a = $ 18
Therefore, the allowance earned by Chinse's brother every week is found to be $ 18.
Kate has $400. She wants to have $430 to buy a couch. How much interest would she have to earn in order to get the additional $30?
Select the best answer from the choices provided.
A. 3%
B. 4.5%
C. 6%
D. 7.5%
Answer:
D) 7.5%
Step-by-step explanation:
We can solve this through guessing and checking, or we can do this mathematically. We will try both approaches.
Mathematically:
We know that to get the extra $30 if we have $100, is a 30% interest. Now, since we have 4x 100, and these numbers are inversely proportional, we will need to divide 30 by 4. Doing this gives us 30/4 = 7.5, so the answer is 7.5%.
Guess and Check:
This way is a bit slower, but we will go through each answer and find how much money we would get from them. So, we would take our percent, change it to a number of that percent, considering we are taking it from 100, and multiply it by 4 since we have $400. We will get each of these respectively:
A) 3% = 3 * 4 = $12
B) 4.5% = 4.5 * 4 = $18
C) 6% = 6 * 4 = $24
D) 7.5% = 7.5 * 4 = $30
As you can see, D) gives us that extra $30, so the answer is D) 7.5%.

The Pre-Image, which refers to the object's initial shape, and the Image, which refers to the object's ultimate shape and location after transformation, are both terms. Transformations can be divided into three categories: translations, reflections, and dilations. There are two types of transformations that can be done to a function: vertical (which affects the y-values) and horizontal (affects the x-values). The four transformation variables are included in the equation of a function that is shown below (a, b, h, and k). changing the log. Take the log of every observation as an example.

A person invests $1000 in an account that earns 5.5% annual interest. Find when
the value of the investment has doubled.
Answer:
P: the principal, the amount invested
A: the new balance
t: the time
r: the rate, (in decimal form)
Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160
Compound Interest:
P: the principal, amount invested
A: the new balance
t: the time
r: the rate, (in decimal form)
n: the number of times it is compounded.
Ex2:Suppose that $5000 is deposited in a saving account at the rate of 6% per year. Find the total amount on deposit at the end of 4 years if the interest is:
P =$5000, r = 6% , t = 4 years
a) simple : A = P(1+rt)
A = 5000(1+(0.06)(4)) = 5000(1.24) = $6200
b) compounded annually, n = 1:
A = 5000(1 + 0.06/1)(1)(4) = 5000(1.06)(4) = $6312.38
c) compounded semiannually, n =2:
A = 5000(1 + 0.06/2)(2)(4) = 5000(1.03)(8) = $6333.85
d) compounded quarterly, n = 4:
A = 5000(1 + 0.06/4)(4)(4) = 5000(1.015)(16) = $6344.93
e) compounded monthly, n =12:
A = 5000(1 + 0.06/12)(12)(4) = 5000(1.005)(48) = $6352.44
f) compounded daily, n =365:
A = 5000(1 + 0.06/365)(365)(4) = 5000(1.00016)(1460) = $6356.12
Find the value of x in each parallelogram
Answer:
Step-by-step explanation:
a) x and 53 are adjacent angles of a parellelogram:
therefore, their sum will be 180 degrees
x + 53 = 180 --> x = 180 - 53 = 127 degrees
b) We know that opposite angles in a parallelogram are equal:
therefore, x = 113 degrees
c) Similarly, x = 80 degrees
d) x + 62 = 180
x = 180 - 62 = 118 degrees

The ff. test scores were recorded by job applicants: 65, 68, 70, 75, 88, 90, 90, 91, 92. What is the mode
In the recorded test scores 90 is the mode, as it appears most frequently in the set of ff test scores.
What do you meant by mode?Job applicants submitted their ff test results, which were as follows: 65, 68, 70, 75, 88, 90, 90, 91, and 92. Following that, the Mean (Average) is 81, Median (Middle) is 88, and Mode (Most Common) is 90. The mode can be calculated quite easily.
After sorting the numbers in a set according to their order—lowest to highest or highest to lowest—count how many times each number appears in the group.
The mode is the one that is most prevalent. the quantity that happens the most frequently, or the quantity that appears the most frequently overall. The mode of the numbers 4, 2, 4, 3, 2, and 2 is 2, since it appears three times, more than any other number. The most frequent number in a set of numbers is called the mode.
To find the mode, we first need to put the test scores in order from lowest to highest:
65, 68, 70, 75, 88, 90, 90, 91, 92
Then we can count how many times each number appears:
65: 1 time
68: 1 time
70: 1 time
75: 1 time
88: 1 time
90: 2 times
91: 1 time
92: 1 time
As we can see, the number 90 appears the most with 2 times, so the mode of this set of data is 90.

Find the circumference and the area of a circle with diameter 3cm
Formula to find the area: A=πr^2
Formula to find circumference: C=2πr
Diameter is twice the length of the radius, so if you're given diameter of 3, the radius is half of that, which that would be 1.5.
A=π(1.5)^2 A= 3.14x1.5^2 = 7.065
Don't forget to round that and that becomes 7.07.

Answer:
Your answer is about 36%.
Step-by-step explanation:
First you do 549-351 = 198.
You do this to find the amount of people supporting the home team.
Then you do 198/549 = 0.36065573770492.
Times this number by 100 and you have your answer of 36.065573770492%.
Answer:
36%

What is a right-angle triangle, exactly?
A right-angled triangle is a particular kind of triangle in which one of the angles is 90 degrees. The combined angles of the other two are 90 degrees.
Perpendicular and the triangle's base make up the sides that the right angle is formed from. The hypotenuse, or third side, is the longest of the three. It is also known as the hypotenuse.
using the sine ratio in the right triangle and the exact value
sin30° = 1/2, then
sin30° = XY/XZ = XY/12 = 1/2 ( cross - multiply)

What is transformation?Transformation is the movement of a point in the coordinate plane. Types of transformation are rotation, reflection, translation and dilation.
Dilation is the increase or decrease of a figure by a scale factor k. If the value of k > 1, then it is an enlargement but if k < 1, it is a reduction.
The point (12, -4) is dilated by a scale factor of 1/4 using the rule (x, y) ⇒ (x/4, y/4). The new point is (4, -1)
