(1/7)³=1³/7³=1/3432⁵=321.4²=1,4×1,4=1,96The formula for any geometric sequence is a n = a 1 · r n - 1 , where a n represents the value of the nth term, a 1 represents the value of the first term, r represents the common ratio, and n represents the term number. What is the formula for the geometric sequence 4, 8, 16, 32, ...?
an = 32 · 2n - 1
an = 2 · 4n - 1
an = 4 · (1/2)n - 1
an = 4 · 2n - 1
Answer:
Step-by-step explanation:instead, try making the subscripts and superscripts stand out:
n-1
a = a * r
n n-1
Believe me, it's worth the extra work to do this!!
Given the sequence -3, -6, -12, -24, you can easily see that the first term,
a is -3. The common factor is 2. Note how (-3)*2=-6, and so on.
1
So, a = -3 and r=2.
1
So the formula for this geometric sequence is
n-1
a = -3*2
n

a cylinder has a height of 19 feet. the volume is 3,818.24 cubic feet. what is the radius?
Answer:
The radius is 32 cubic feet
Step-by-step explanation:
The formula to find the volume of a cylinder is V=Bh or V=πr2h. So you would need to work backwards because you already have the volume and height.
3,818.24= 3.14r2*19
3,818.24= 3.14r*38
Because of the associative property, you can multiply 3.14 by 38
which is 119.32
So the next expression would be
3,818.24= 119.32r
How do you reverse multiplication? You need to divide both sides. In this case, you need to divide 3,818.24 by 119.32.
To get 32=r

Pythagorean theorem HELP PLZ i am doing other ones can you plz do this one
Answer:
it is the first answer
Step-by-step explanation:
have a good day :)
Answer:
it is the 1st one.
Step-by-step explanation:
The pythagorean theorem is [tex]a^{2} + b^{2} = c^{2}[/tex], a and b standing for the two legs and c stands for the hypotenuse (slanted line connecting the two). Since [tex]2^{2} = 4[/tex] and [tex]3^{2} = 9[/tex], we add 4 and 9 to get 13. Since 3 is already squared, we can look at it like [tex]\sqrt{13}[/tex]. Therefore, the first answer, "2,3,[tex]\sqrt{13}[/tex]", is correct. Hope this helped!! :]
Use the Distributive Property to solve the problem. [Example: 4(6+3) = 4(6)+4(3) = 24 + 12 = 36] 9(8 + 4)
(sorry for spamming these questions, its part of an assignment i HAVE to do well on to raise my horrible math grade)
please let me know if you need help on anything else.
4(6+3)=4(6)+4(3)=24+12=36.
multiply 4(6) and 4(3).
4x6=24 4x3=12
24+12=24+12=24+12=36
24+12=36
9(8+4)
72+36=108

Answer:
2x = 6
Step-by-step explanation:
Simplify the following algebraic expressions.
- 6x + 5 + 12x -6
2(x - 9) + 6(-x + 2) + 4x
3x2 + 12 + 9x - 20 + 6x2 - x
(x + 2)(x + 4) + (x + 5)(-x - 1)
1.2(x - 9) - 2.3(x + 4)
(x2y)(xy2)
(-x2y2)(xy2)
Solution
Group like terms and simplify.
- 6x + 5 + 12x -6 = (- 6x + 12x) + (5 - 6)
= 6x - 1
Expand brackets.
2(x - 9) + 6(-x + 2) + 4x = 2x - 18 - 6x + 12 + 4x
Group like terms and simplify.
= (2x - 6x + 4x) + (- 18 + 12) = - 6
Group like terms and simplify.
3x2 + 12 + 9x - 20 + 6x2 - x
= (3x2 + 6x2) + (9x - x) + (12 - 20)
= 9x2 + 8x - 8
Expand brackets.
(x + 2)(x + 4) + (x + 5)(- x - 1)
= x2 + 4x + 2x + 8 - x2 - x - 5x - 5
Group like terms.
= (x2 - x2) + (4x + 2x - x - 5x) + (8 - 5)
= 3
Expand and group.
1.2(x - 9) - 2.3(x + 4)
= 1.2x - 10.8 - 2.3x - 9.2
= -1.1x - 20
Rewrite as follows.
(x2y)(xy2) = (x2 x)(y y2)
Use rules of exponential.
= x3 y3
Rewrite expression as follows.
(-x2y2)(xy2) = -(x2 x)( y2 y2)
Use rules of exponential.
= - x3 y4
Simplify the expressions.
(a b2)(a3 b) / (a2 b3)
(21 x5) / (3 x4)
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
(4x - 12) / 4
(-5x - 10) / (x + 2)
(x2 - 4x - 12) / (x2 - 2 x - 24)
Solution
Use rules of exponential to simplify the numerator first.
(a b2)(a3 b) / (a2 b3) = (a4 b3) / (a2 b3)
Rewrite as follows.
(a4 / a2) (b3 / b3)
Use rule of quotient of exponentials to simplify.
= a2
Rewrite as follows.
(21 x5) / (3 x4) = (21 / 3)(x5 / x4)
Simplify.
= 7 x
(6 x4)(4 y2) / [ (3 x2)(16 y) ]
Multiply terms in numerator and denominator and simplify.
(6 x4)(4 y2) / [ (3 x2)(16 y) ] = (24 x4 y2) / (48 x2 y)
Rewrite as follows.
= (24 / 48)(x4 / x2)(y2 / y)
Simplify.
= (1 / 2) x2 y
Factor 4 out in the numerator.
(4x - 12) / 4 = 4(x - 3) / 4
Simplify.
= x - 3
Factor -5 out in the numerator.
(-5x - 10) / (x + 2) = - 5 (x + 2) / (x + 2)
Simplify.
= - 5
Factor numerator and denominator as follows.
(x2 - 4x - 12) / (x2 - 2x - 24) = [(x - 6)(x + 2)] / [(x - 6)(x + 4)]
Simplify.
= (x + 2) / (x + 4) , for all x not equal to 6
Solve for x the following linear equations.
2x = 6

Answer:
[tex]\Huge\boxed{25.13ft^3}[/tex]
Step-by-step explanation:
Hello There!
It says the tree has a cone like structure
The formula for volume of a cone is
[tex]V=\pi r^2\frac{h}{3}[/tex]
where r = radius and h = height
note it says to use 3.14 for pi
so given the dimensions all we have to do is plug in the values into the formula
[tex]V=3.14*2^2*\frac{6}{3}\\2^2=4\\4*3.14=12.56\\\\\frac{6}{3} =2\\2*15.56=25.133[/tex]
Our last step is to round to the nearest foot
So we can conclude that the tree has a volume of 25.13ft³

I have to do a Hinduism poster for the teacher who does not really like me so can anybody I really don't care who give me tips on what should I put in it??????????????????
- Hindu symbols
- This will be a great start to a Hindu themed poster as the symbols mean a lot, and you could even put a message with the symbols
- Ganesha (sacred elephant) or Hanuman (The monkey god)
- Putting sacred animals in the poster will really bring out the theme and idea of the poster itself.
- A temple
- Putting a temple in the poster will overall represent the theme of this poster, as Hindu's spend a lot of time in their temple's
- Murti (statue or image of the god being worshipped0
- To top it off add a religious symbol in there
Hinduism: A major religion started in South Asia, which was developed by Vedic Religion

−2x − 10 = 15 I'm really un smart
Answer:
x = -12.5
Step-by-step explanation:
your goal is to get x alone so
-2x - 10 = 15
(add ten to both sides)
-2x = 25
(divide -2 to both sides)
x = -12.5
remember that whatever u do to one side of the equation, you have to do to the other so they even out!

Andy is buying carpet squares for his living room. The length of the room is 20 feet, and the width is 16 feet. Each carpet square covers 4 square feet. How many carpet squares will Andy need to purchase to cover the room?
A) 9 carpet squares
B) 36 carpet squares
C) 80 carpet squares
D) 144 carpet squares
Answer:
The area of his living room is 320, and since the carpets cover 4 sq feet then we have 320 / 4 = 80.
Hope this helped and brainliest please
Answer: C. 80 carpet squares
Step-by-step explanation:
Find the area of the room:
A = l*w = 20 * 16 = 320 sq ft
The room is 320 square feet and each carpet square covers 4 square feet
320 / 4 = 80 carpet squares
