The 3rd term of the geometric sequence is 6.
Describe Equation.In mathematics, an equation is a statement that two expressions are equal. It usually contains one or more variables, which are unknown quantities that can take on different values. Equations are used to represent relationships between quantities, and they can be used to solve problems by finding the values of the variables that make the equation true.
An equation typically consists of two sides, separated by an equal sign. Each side can contain numbers, variables, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots. For example, the equation:
2x + 3 = 7
contains the variable x, as well as constants 2, 3, and 7, and mathematical operations of addition and multiplication.
Equations can be solved by applying algebraic techniques to isolate the variable on one side of the equation. For example, to solve the above equation for x, we can first subtract 3 from both sides to get:
2x = 4
Then, we can divide both sides by 2 to get
x = 2
This is the solution to the equation, which means that x must be equal to 2 in order to make the equation true.
Equations are used in many areas of mathematics, including algebra, calculus, geometry, and trigonometry. They are also used in physics, engineering, and other sciences to model physical phenomena and solve problems related to them.
Let's call the first term of the geometric sequence "a" and the common ratio "r".
The formula for the nth term of a geometric sequence is:
an = a *[tex]r^(n-1)[/tex]
We are given that the 2nd term is 2, so we know that:
a * r = 2 --(1)
We are also given that the 5th term is 432, so we know that:
a * [tex]r^4[/tex] = 432 --(2)
Now we need to solve for "a" and "r" in order to find the 3rd term.
First, let's solve equation (1) for "a":
a = 2 / r
Now we can substitute this expression for "a" into equation (2):
(2/r) *[tex]r^4[/tex]= 432
Simplifying, we get:
[tex]r^3[/tex]= 54
Taking the cube root of both sides, we get:
r = 3
Now we can substitute this value for "r" back into equation (1) to solve for "a":
a * 3 = 2
a = 2/3
So the first term of the sequence is 2/3 and the common ratio is 3.
Now we can use the formula for the 3rd term of a geometric sequence:
a3 = a * [tex]r^(3-1)[/tex]
a3 = (2/3) *[tex]3^2[/tex]
a3 = (2/3) * 9
a3 = 6
Therefore, the 3rd term of the geometric sequence is 6.

For the end of the year party, Lone Star Middle School ordered 242 pizzas. There were eight fewer veggie pizzas than there were pepperoni pizzas. There were three times as many combo pizzas as pepperoni pizza. Write an equation for the situation.
Determine how many of each kind of pizza was ordered
There were 24 pepperoni pizza, 16 veggie pizza and 72 combo pizza
What is pizza?Pizza is a dish of Italian origin consisting of a usually round, flat base of leavened wheat-based dough topped with tomatoes, cheese, and often various other ingredients, which is then baked at a high temperature, traditionally in a wood-fired oven. A small pizza is sometimes called a pizzetta.
Calculation of the each kind of pizzas:
Let us assume the number of pepperoni pizzas be x
So,
pepperoni = x
veggie = x - 8
combo = 3x
Since
The total Pizza is 112
So,
x + x - 8 + 3x = 112
5x - 8 = 112
5x = 112 + 8
5x = 120
x = 24
Now
x - 8 = 16
3x = 72

solve for x. line 1. 27degrees line 2. (3x)degrees
The measure of the angle of x is 69.
In order to find the measure of one angle, given the measure of the other angle on the same straight line, you must use the relationship between the angles.
When two angles are on the same line and adjacent, they must add up to 180 degrees. This means that the two angles, x degrees and (2x-27) degrees, must add up to 180 degrees. We can use this to solve for x. We can set up an equation to represent this relationship:
x + (2x - 27) = 180
We can now use the distributive property to solve for x.
3x - 27 = 180
Adding 27 to both sides of the equation, we get:
3x = 207
Dividing both sides of the equation by 3, we get:
x = 69
Therefore, the measure of the angle is x = 69 degrees.

The temperature at half past eleven would be 2 °C.
What is algebraic expression?In mathematics, an algebraic expression is an expression built up from constant algebraic numbers, variables, and the algebraic operations.
Given is that the temperature in Austria one morning was -5 degrees Celsius at eight o clock and increased by 2 degrees Celsius every hour until twelve o clock.
We can write the temperature variation as a function of hour {x} as -
T{x} = (- 5 + 2{x})°C
For half past eleven, we will have -
{x} = 3.5
So, we can write -
T{x} = (- 5 + 2 x 3.5)°C

Conan fills 5 tubes. 2 tennis balls are left. How many tubes does Conan need to put away all the tennis balls?
Therefore , the solution of the given problem of linear equation comes out to be conan needs one more tube to put away the remaining 2 tennis balls.
A linear equation is precisely what?A straightforward regression curve is created using the equation y=mx+b. The y-intercept is m, and the slope is B. The previous line is usually referred to as a "math equation mixing numerous variables," even though y / y represent independent components. Only two variables are present in bivariate linear equations. There are no known solutions to application issues involving linear equations.
Here,
We know that Conan has 5 tubes, and that 2 tennis balls are left unfilled. This means that he has already filled up 5 - 1 = 4 tubes.
Each tube can hold a certain number of tennis balls, so we need to know how many tennis balls each tube can hold. Once we know that, we can figure out how many tubes are needed to hold the remaining 2 tennis balls.
Let's say each tube can hold n tennis balls. Then, the 4 filled tubes have a total capacity of 4n tennis balls. We also know that there are 2 tennis balls left unfilled. Therefore, we can set up the following equation:
4n + 2 = 5n
Simplifying this equation, we get:
2 = n
So each tube can hold 2 tennis balls. Therefore, Conan needs one more tube to put away the remaining 2 tennis balls.

how to calculate inverse sin?
The inverse of the sine can be calculated by using the formula sin^-1(x) = arcsin(x)
To calculate the inverse sine (sin^-1) of a value, you can use a scientific calculator or look up the value in a trigonometric table. However, if you want to understand how to do it manually, follow these steps:
Make sure the value you are calculating the inverse sine of is between -1 and 1, inclusive. If it is not, the inverse sine is undefined.
Write down the value you want to find the inverse sine of.
Use the formula: sin^-1(x) = arcsin(x), where x is the value you wrote down.
Substitute the value of x into the formula and calculate the inverse sine using a calculator or by using a series expansion or Taylor series approximation.
The inverse sine function returns a value in radians, so you may need to convert it to degrees if that's the unit you're working with.

I ride four times faster than I jog. If a trip took me 45 minutes and I spent 15 of these minutes jogging 3km, how far did I ride ?
Answer:
24km
Step-by-step explanation:
15 min (jogging)
30 min (cycling)
3km/15 min (jogging)
1km/5min (jogging)
4km/5min (cycling)
30÷5= 6
4×6= 24km
Distance covered during riding is 24 km.
What is meant by speed ?Speed of an object is defined as the rate of change of the distance travelled.
Here,
Speed is the distance travelled in a given time.
Total time given, t = 45 minutes
Time taken for jogging, t₁ = 15 minutes
So, time taken for riding, t₂ = t - t₁
t₂ = 45 - 15
t₂ = 30 minutes
Distance covered during jogging, d₁ = 3 km
Therefore speed of jogging, v₁ = d₁/t₁ = 3/15
v₁ = 0.2 km/min
So, speed of riding, v₂ = 4v₁ = 4 x 0.2
v₂ = 0.8 km/min
Therefore distance covered during riding, d₂ = v₂ x t₂
d₂ = 0.8 x 30
d₂ = 24 km
Hence,
Distance covered during riding is 24 km.

Mr. Quesada took out a loan for $12,000. To pay it back, he will make 24 monthly payments of $629. How much will he pay in interest?
Answer:
$3,096
Step-by-step explanation:
To find the total interest Mr. Quesada will pay, we need to first calculate the total amount he will pay back, and then subtract the original amount borrowed.
The total amount Mr. Quesada will pay back over 24 months is:
$629 x 24 = $15,096
Subtracting the original loan amount, we get:
$15,096 - $12,000 = $3,096
So Mr. Quesada will pay a total of $3,096 in interest over the course of the loan.
