Answer:
C
Step-by-step explanation:
The n th term formula of a geometric sequence is
[tex]a_{n}[/tex] = a [tex]r^{n-1}[/tex]
where a is the first term and r the common ratio
Using the second and fourth term, then
ar = 6 → (1)
ar³ = 54 → (2)
Divide (2) by (1)
[tex]\frac{ar^3}{ar}[/tex] = [tex]\frac{54}{6}[/tex] = 9
r² = 9 ⇒ r = [tex]\sqrt{9}[/tex] = 3 → C
The answer would be C.

Find the area of this regular polygon.
Round to the nearest tenth.
Rounding to the nearest tenth, the area of the regular pentagon is approximately 175.1 square centimeters.
To find the area of the regular pentagon, we can use the formula:
Area = (5/2) * s * r
Where s is the length of one side of the pentagon and r is the distance from the midpoint of the pentagon to one of its vertices.
We are given that s = 8.37 cm and r = 8.37 cm.
Plugging these values into the formula, we get:
Area = (5/2) * 8.37 * 8.37
Area = (5/2) * 70.0569
Area = 175.14225
Rounding to the nearest tenth, the area of the regular pentagon is approximately 175.1 square centimeters.

PLEASE HELP
Answer:
The factorization of [tex]x^{3}+8[/tex] is [tex](x+2)(x^{2} -2x+4)[/tex]
Step-by-step explanation:
The problem is a sum of cubes factorization, this type of factorization applies only in binomials of the form [tex](a^{3} +b^{3} )[/tex] which means numbers that have exact cubic root and the exponents of the letters a and b are multiples of three.
Sum of cubes equation
[tex](a^{3} +b^{3} )= (a+b)(a^{2} -ab+b^{2})[/tex]
So, let's factor [tex]x^{3}+8[/tex]
we have to bring the equation to the form [tex](a^{3} +b^{3} )[/tex]
[tex]x^{3}+8=x^{3}+2^{3}[/tex] con [tex]a=x[/tex] y [tex]b=2[/tex]
Solving using sum of cubes equation
[tex](x^{3} +2^{3} )= (x+2)(x^{2} -(x)(2)+2^{2})[/tex]
[tex](x^{3} +2^{3} )=(x+2)(x^{2} -2x+4)[/tex]

The value of log a(30a)^3
Answer:
8.6
Step-by-step explanation:
The expression 9x represents the number of miles Allison hiked, and 4x + 5 represents the number of miles that Adrian hiked in x days. Write an expression to show how many more miles Allison hiked than Adrian.
Question 7 options:
5x – 5
–5x + 5
5x + 5
13x + 5
For this case we have that Allison traveled 9x miles, while Adrian traveled 4x + 5 miles. The variable "x" represents the number of days.
We want to know how many miles of Allison toured Adrian, for this we subtract:[tex]9x- (4x + 5) =[/tex]
We take into account that:[tex]- * + = -[/tex]
[tex]9x-4x-5 =\\5x-5[/tex]
ANswer:
[tex]5x-5[/tex]
Answer:
Expression to show how many more miles Allison hiked than Adrian is:
5x-5
Step-by-step explanation:
Number of miles Allison hiked = 9x
Number of miles that Adrian hiked = 4x+5
Miles Allison hiked more than Adrian
= 9x-(4x+5)
=9x-4x-5
=5x-5
Hence, expression to show how many more miles Allison hiked than Adrian is:

a segment has and endpoint at (-6, 8). The midpoint is at (-6, 2). What are the coordinates of the other endpoint?
Answer:
(-6,-4)
Step-by-step explanation:
The first endpoint of the line is (-6,8), we can call
x_1 = -6
and
y_1 = 8
Let the last endpoint have coordinates (x_2,y_2)
Also, the midpoint formula is:
(x_1+x_2)/2 , (y_1+y_2)/2
Now, plugging these values is the formula, we get:
(-6+x_2)/2 = -6
-6+x_2=-12
x_2=-12+6 = -6
x_2 = -6
Also
(8+y_2)/2=2
8+y_2=4
y_2=4-8=-4
y_2 = -4
The coordinates of the other endpoint is (-6,-4)
A $78.00 pair of shoes cost $84.63 after tax is added. What percentage of the cost is tax?
Answer:
The percent of the cost tax is:
8.5%
Step-by-step explanation:
Cost of shoe before tax= $ 78
Cost of shoe after tax= $ 84.63
This means that the cost of tax is:
Cost of shoe after tax-cost of shoe before tax
= $ 84.63-$ 78
= $ 6.63
Now, the percent of tax is calculated as:
[tex]Percent\ tax=\dfrac{Cost\ of\ tax}{Cost\ of\ shoe\ before\ tax}\times 100\\\\\\Percent\ tax=\dfrac{6.63}{78}\times 100\\\\\\Percent\ tax=8.5\%[/tex]
Hence, the percent tax is:
8.5%

Which answers is it a b or c
Answer:
B
Step-by-step explanation:
Use the equation for the area of a parallelogram.
[tex]A=bh[/tex]
Now solve for [tex]h[/tex].
[tex]h=\frac{A}{b}[/tex]
Plug in.
[tex]h=\frac{450}{15}[/tex]
[tex]h=30[/tex]
Answer:
B, 30 inches
Step-by-step explanation:
the areao of a parallelogram's formula is A = bh
in the word problem, we are given A and b, so we plug that into the formula to solve for h
450 = 15h < divide both sides by 15 to get h alone
450/15 = 30
15h/15 = h
h = 30
the solution to the word problem is B, 30 inches

2 and one half cakes are divided up into 18 pieces for guests how much cake will each person get
Well if you were to do 18 ÷ 2 it would be 8. But since this is 8 and a half let's use 2.5. So, let's do this.
18 ÷ 2.5 = 7.2.
But since cake can't be exactly that we can estimate to 7 since it is the closest so, the answer is 7 pieces of cake.
Express this equation in logarithmic form. y = 10^x
X=
For this case we must find the value of the variable "x" of the following equation:
[tex]y = 10^{x}[/tex]
We rewrite the equation as:
[tex]10 ^ {x} = y[/tex]
We take the logarithmic base 10 from both sides of the equation to remove the variable from the exponent.
[tex]log (10 ^ {x}) = log (y)\\x (log (10)) = log (y)[/tex]
The logarithmic base 10 of 10 is 1.
[tex]x * 1 = log (y)\\x = log (y)[/tex]

simplify expression 49 with an exponent of 1/2
The answer is:
The simplified form of the given expression is 7.
[tex]49^{\frac{1}{2}}=\sqrt[2]{49^{1}}=\sqrt[2]{49}=7[/tex]
Why?To simplify the given expression, we must remember the following property of roots:
[tex]a^{\frac{m}{n}}=\sqrt[n]{a^{m} }[/tex]
We are given the expression:
[tex]49^{\frac{1}{2}}[/tex]
Which can be also written as:
[tex]49^{\frac{1}{2}}=\sqrt[2]{49^{1}}=\sqrt[2]{49}[/tex]
Then, simplifying we have:
[tex]\sqrt[2]{49}=7[/tex]
Hence, the simplified form of the given expression is 7.
Have a nice day!
Answer: 7
Step-by-step explanation: To simplify [tex]49^{1/2}[/tex], it's important to understand that an exponent of 1/2 means that we take the square root of the base. In other words, [tex]49^{1/2}[/tex] means the same thing as the square root of 49 or [tex]\sqrt{49}[/tex] and the square root of 49 is 7.
This means that [tex]49^{1/2}[/tex] is 7.
A nature preserve has a population of fourteen black bears. They have been tagged #1 through #14, so they can be observed over time. Two of them are randomly selected and captured for evaluation. One is tested for worms and one is tested for ticks. What is the probability that bear #3 is tested for worms and bear #5 is tested for ticks?
Answer:
1/182 or 0.55%
Step-by-step explanation:
There are 2 ways to approach this problem (and both give the same answer!).
First method: probability for each test.
First test, worms: There's 1/14 chances for bear #3 to be selected, since there are 14 bears total.
Second test, ticks: There's 1/13 chances for bear #5 to be selected, since only 13 bears remain (#3 cannot be tested for both ticks and worms).
So, to obtain the total probability, we multiply 1/14 with 1/13 = 1/182
Second method: permutations
We can see the problem from a permutations perspective. How many permutations can we have for 2 bears to be tested? It's a permutation since the order is important. (#3 ticks + #5 worms ≠ #3 worms + #5 ticks)
[tex]P(14,2) = \frac{14!}{(14 - 2)!} = 182[/tex]
There are 182 permutations possible, ONE of which is bear #3 is tested for worms and bear #5 is tested for ticks.
So, once again, 1/182.

1,2 cause of the o and y axis
The vertex is where the parabola changes directions, or in simpler terms, at the parabolas lowest point. Unless the parabola is upside down, then the vertex is where the highest point is.
The acid of symmetry is the line where the parabola can be divided evenly. This is almost always where the vertex is, except it continues on.
The y-intercept is where the parabola intersects with the y-axis.

The coefficient of 'a' is 5.
The coefficient of 'b' is 9.
The coefficient of the constant term '-4' is -4 (or you can think of it as -4 times '1').
The coefficient in the expression 5a + 9b - 4 is the number that multiplies or is associated with a variable. In this expression:
The coefficient of '5a' is 5.
The coefficient of '9b' is 9.
The constant term '-4' does not have a variable and can be considered as a coefficient of '1' for the constant.
So, in summary:
