What is the explicit rule for this geometric sequence?
2/9,2/3,2,6,...
an=3(29)n−1
an=3(29)n
an=29⋅3n−1
an=29⋅3n
Answer:
Tn = 2/3^(n-1)
Step-by-step explanation:
The nth term of a geometric progression is expressed as
Tn = ar^{n-1}
a is the first term
n is the number of terms
r is t common ratio
From the sequence
a = 2/9
r = (2/3)/(2/9) = 2/(2/3) =3
Substitute
Tn = 2/9(3)^(n-1)
Tn = 2/3^(n-1)
Hence the required equation is Tn = 2/3^(n-1)
Answer:
the actual answer is [tex]a_{n}[/tex][tex]=(\frac{2}{9} )3^{n-1}[/tex]

An artist made a cone out of stainless steel, then sliced it into 3 pieces to use to make a sculpture. The original cone and the 3 pieces are shown below. ( I have attached the picture)
What is the volume of the largest piece?
A. 2,375 π cubic centimeters
B. 2,500 π cubic centimeters
C. 3,250 π cubic centimeters
D. 3,375 π cubic centimeters
Answer:
3375 [tex]\pi \\[/tex] cubic centimeters
Step-by-step explanation:
Trick question: The largest piece is the entire cone.
First lets identify the equation for volume.
V= 1/3 h pi r^2
h=45
r=15
V= 1/3 45 * pi 15^2
v= 15* pi 225
3375 pi
You keep pi because the answer has pi.

Step-by-step explanation:
- 3x - 10 = 32
X = 14
X = -14
X = -10
x =10
Answer: -14
Step-by-step explanation:
-3x-10=32
Since the 10 is negative you have to add 10 on the right side of the equal sign. you add 10 to the negative 10 and it cancels out and becomes zero. Then you have to add 10 to the 32 and it becomes 42. Divide the 42 by negative 3 and you get -14.

1. If the diameter of a circular object is 10 feet. Find the radius and the circumference. Use 3.14 for π.
2. Find the perimeter of the window. R = 4ft
Answer:
1.
[tex]Radius = 5ft[/tex]
[tex]Circumference = 31.4\ ft[/tex]
2.
[tex]Perimeter = 25.12\ ft[/tex]
Step-by-step explanation:
Solving (1):
Given
[tex]Diameter = 10ft[/tex]
Required
Determine the radius and circumference
Radius is calculated as follows:
[tex]Radius = \frac{1}{2} * Diameter[/tex]
[tex]Radius = \frac{1}{2} * 10ft[/tex]
[tex]Radius = 5ft[/tex]
The circumference is calculated using:
[tex]Circumference = 2 * \pi * Radius[/tex]
[tex]Circumference = 2 * 3.14 * 5ft[/tex]
[tex]Circumference = 31.4\ ft[/tex]
Solving (2):
Given
[tex]R = 4ft[/tex]
Assume that the window is circular, the perimeter is calculated as follows:
[tex]Perimeter = 2 * \pi * R[/tex]
[tex]Perimeter = 2 * 3.14 * 4ft[/tex]
[tex]Perimeter = 25.12\ ft[/tex]
At the beginning of last year,there were 368 students at the elementary school.By the beginning of this year,72 of those students have moved to other school districts and 64 new students arrived. about how many students started the school year this year
Answer:
360 students
Step-by-step explanation:
We start off with 368.
Then 72 leave the school, so subtract 72 from our total.
368 - 72 = 296
But, then 64 new students join, so add this to our new total.
296 + 64 = 360.

I have a cockroach problem in my living room. Don't ask how but I counted 64 cockroaches today. And they are
growing at a rate of 25% every day.
How many cockroaches do you think I'll have after three days?
If they are growing at a rate of 25% every day you can expect to have approximately 100 cockroaches in your living room.
What is growth rate?Growth rate refers to the rate at which something (such as a population, a quantity, or a value) increases or decreases over a certain period of time.
Assuming that the growth rate is compounded daily, we can calculate the number of cockroaches you will have after three days using the formula for exponential growth:
[tex]N = N_0(1 + r)^t[/tex]
Where:
N₀ is the initial number of cockroaches (64 in this case)
r is the growth rate (25% or 0.25 in decimal form)
t is the time in days (3 in this case)
N is the number of cockroaches after t days
Plugging in the values, we get:
[tex]N = 64(1 + 0.25)^3[/tex]
[tex]N = 64(1.25)^3[/tex]
N = 64(1.5625)
N = 100
Thus, after three days, you can expect to have approximately 100 cockroaches in your living room.

find the slope and y-intercept of the line in the graph. Express the answers as simplified fractions, if necessary.
Answer:
y=1 3/5x+-5
Step-by-step explanation:
So the y intercept is where your slope meets the middle, basically the y. So it hit the y on -5. And the rise and run 8/5 rise is 8 and run is 5. 8/5= 1 3/5. in equation it is y=1 3/5x+-5.
Choose the equation that represents the line that passes through the point (-1, 6) and has a slope of -3.
y=-3x + 3
y=-3x - 6
y = 3x - 3
y = 3x - 1
Answer:
Equation of line is [tex]\mathbf{y=-3x+3}[/tex]
Option A is correct.
Step-by-step explanation:
We need to write an equation that represents the line that passes through the point (-1, 6) and has a slope of -3.
The equation will be of slope-intercept form: [tex]y=mx+b[/tex]
where m is slope and b is y-intercept
We are given slope m =-3, we need to find y-intercept b
Finding y-intercept
using slope m=-3 and point (-1, 6)
[tex]y=mx+b\\6=-3(-1)+b\\6=3+b\\b=6-3\\b=3[/tex]
So, y-intercept b is 3
Now the equation of line having slope m= -3 and y-intercept b = 3 is
[tex]y=mx+b\\y=-3x+3[/tex]
Equation of line is [tex]\mathbf{y=-3x+3}[/tex]
Option A is correct.

From the region (2, ∞) of the inequality the values -1, 0, and 2 are not in the region, but the value 3 is in the region so p = 3 is the solution to the inequality option (E) is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.
We have inequality:
10p - 8 >12
10p > 12 + 8
10p > 20
p > 2
p ∈ (2, ∞)
Thus, from the region (2, ∞) of the inequality the values -1, 0, and 2 are not in the region, but the value 3 is in the region so p = 3 is the solution to the inequality option (E) is correct.

Simply put, expressing a radical in its lowest extreme form implies simplifying it and that there are no more squared roots, cube roots, 4th roots, and so on to find. This also entails eliminating any radical from a fraction's base, and further calculation can be defined as follows:
