the 6th term of a gp is -2/29,and it's first term is 18.what is the common ratio
Answer:
-0.329
Step-by-step explanation:
The formula for Geometric ratio is
an = ar^n - 1
Where
a = First term = 18
r = Common ratio = ?
n = Number of term= 6
Hence
a6 = 18 × r^6-1
From the question
a6 = -2/29
Hence:
-2/29 = 18 × r^6-1
-2/29 = 18 × r⁵
Divide both sides by 18
-2/29 ÷ 18 = 18 × r⁵/18
-2/29 × 1/18 = r⁵
r⁵ = -1/261
Take the fifth root of both sides
⁵√(r⁵) = ⁵√(-1/261)
r = -0.3286032834
Approximately = -0.329
Therefore, Common ratio = -0.329

Answer: D
Step-by-step explanation:
The triangle below is equilateral. Find the length of side x x in simplest radical form with a rational denominator
Answer:
x = √30
Step-by-step explanation:
We are given an equilateral triangle, so the angles will all be (180/3). = 60
Therefore, the angle opposite x is 60° ; hence. We can use trigonometry to obtain the value of x
Tan θ = opposite / Adjacent
Tan 60 = x / √10
Tan 60 = √3
Hence,
√3 = x / √10
x = √3 * √10
x = √30

Answer:
The answer is 34.5cm2. (don't blame meh if wrong)
Step-by-step explanation:
Step 1: Find the area of the square; 4.6 x 3.2 = 14.72
Step 2: Find the bottom length to find the area of the triangle; 7.5 - 3.2 = 4.3
Step 3: Find the area of the triangle; 4.3 x 4.6 = 19.78

what is an equation in standard form of an ellipse centered at the origin with vertex (-4,0) and co-vertex (0,5)???
Answer:
[tex]\frac{x^2}{16}+\frac{y^2}{25}=1[/tex]
Step-by-step explanation:
The equation of an ellipse with a center at [tex](h, k)[/tex] and vertices at [tex](h\pm a, k)[/tex] and [tex](h, k\pm b)[/tex] is given by [tex]\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1[/tex].
Since two vertices are located at (-4, 0) and (0, 5), the other vertices must be located at (4, 0) and (0, -5).
What we know:
Center of (0, 0)From [tex](h\pm a, k)[/tex], [tex]a[/tex] must be 4From [tex](h, k\pm b)[/tex], [tex]b[/tex] must be 5Thus, we have:
[tex]\frac{(x-0)^2}{4^2}+\frac{(y-0)^2}{5^2}=1\implies \boxed{\frac{x^2}{16}+\frac{y^2}{25}=1}[/tex]

Find the side length of x (trigonometry)
Answer:
x=12.124
Step-by-step explanation:
here 7 and x are the legs of the triangle where as 14 is hypotenuse because it is opposite opposite to 90 degree.
using pythagoras theorem
a^2 + b^2 = c^2
here and b are legs and c is hypotenuse
7^2 + x^2 = 14^2
49 + x^2 = 196
x^2 =196-49
x^2 =147
x=[tex]\sqrt{147}[/tex]
x=12.1243
x=12.124 (after converting to the nearest hundredth)

99 points waiting for the person that answers the question
Answer:
No
Step-by-step explanation:
This is from a website so you might have to rephrase it but Direct variation describes a simple relationship between two variables . We say y varies directly with x (or as x , in some textbooks) if:
y=kx
for some constant k , called the constant of variation or constant of proportionality . (Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x .")
This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.
The graph of the direct variation equation is a straight line through the origin.

Write an expression in simplest form that represents the total amount. Suppose you buy 3 shirts that each cost s dollars, a pair of shoes for $50, and jeans for $30. a. 3+80s b. 83s c. s(80s) d. 3s+80
Answer:
d
Step-by-step explanation:
3 shirts that each costs s dollars would be 3s
jeans is $30, pair of shoes is $50, add $30+$50 and you'll end up with $80
so, an expression in the simplest form that represents the total cost would be:
d. 3s+80
The expression in simplest form that represents the total amount is option d. 3s+80.
In order to understand why this is the correct expression, let us break down the given information step-by-step:
1. You buy 3 shirts that each cost s dollars. This implies that since you are buying 3 shirts, the cost of the shirts is 3s dollars.
2. You also buy a pair of shoes for $50. So, the cost of the shoes is $50.
3. Additionally, you buy jeans for $30.
To find the total amount, we need to add up the cost of the shirts, shoes, and jeans together.
The cost of the shirts is 3s dollars.
The cost of the shoes is $50.
The cost of the jeans is $30.
The cost of the shirts (3s) plus the cost of the shoes ($50) plus the cost of the jeans ($30) is: 3s + $50 + $30.
Therefore, the total amount is 3s + $50 + $30.
Since $50 and $30 are constant values, simplifying the expression further yields: 3s + 80.
Hence, the correct expression in simplest form that represents the total amount is option d. 3s + 80.

[tex]\frac{b^x}{b^y} = b^{x-y}[/tex]
[tex]\frac{9^6 \cdot 9^0 \cdot 9^4}{9^7} = 9^{6 + 0 + 4 -7} = 9^{10-7} = 9^3[/tex]
Answer:
9^3
Step-by-step explanation:
When we want to multiply exponents, we use the formula a^m x a^n= a^m+n.
In this case, we can see that 9 is our a, and their respective exponents are mn and n.
9^6 x 9^0 x 9^4 = 9^6+0+4= 9^10
When dividing exponents we subtract the exponents for each number from the top. For example, 9^10/9^7= 9^10-7= 9^3
If we want to simplify this even further, 9^3 = 729.

A tube of toothpaste holds 75 ml.
How many tubes can be filled using 3 litres of toothpaste?
Pls help
Answer:
40 tubes
Step-by-step explanation:
1 liter = 1,000 milliliters
2 liters = 2,000 milliliters
3 liters = 3,000 milliliters
A tube of toothpaste = 75 ml
How many tubes can be filled using 3 litres of toothpaste?
Let
x = number of tubes
x tubes of toothpaste = 3000 ml
x = 3000 ml / 75 ml
x = 40
x = number of tubes = 40 tubes
