The value of the finite sum equation is,
⇒ S = 5 (3ⁿ - 1)
We have to given that;
Sequence is,
⇒ 10 + 30 + 90 + ..... = 2657200
Now, We get;
Common ratio = 30/10 = 3
Hence, Sequence is in geometric.
So, The sum of geometric sequence is,
⇒ S = a (rⁿ- 1)/ (r - 1)
Here, a = 10
r = 3
Hence, We get;
⇒ S = 10 (3ⁿ - 1) / (3 - 1)
⇒ S = 10 (3ⁿ - 1) / 2
⇒ S = 5 (3ⁿ - 1)

Which of the following sets of sides does not form a right triangle?
6.8.10
8.15, 17
7.24.26
5, 12, 13?
Answer:
7, 24, 26
Step-by-step explanation:
6 squared is 36 and 8 squared is 64. Add them together and you get 100, which is 10 squared. Do the same for the other ones and you'll notice that 7 squared and 24 squared added together is 625, which is not 26 squared. In my head 25 squared is 625(check if you don't believe me) so I know that the answer is the third one. The basic formula for a right triangle is a^2 + b^2 = c^2, and that's how you find if three numbers form a right triangle or not. Hope this helps :)

When the angle of elevation to the sun is 42 a flagpole casts a shadow that is 21 ft long. What is the height of the flagpole to the nearest foot?
Answer:
18.91 cm
Step-by-step explanation:
Let x represent the height of the flag pole
Tan= opposite/ adjacent
Tan 42°= x/21
x= Tan 42° × 21
= 0.9004 × 21
= 18.91 cm
Hence the height is 18.91 cm
Juanita had 20 dollars to spend on 3 gifts. She spent 8 3 4 dollars on gift A and 4 1 2 dollars on gift B. How much money did she have left for gift C?
Answer:
the amount left for gift c is $7.54
Step-by-step explanation:
The computation of the amount left for gift c is shown below:
= Total money to spend - spent on gift A - spent on gift B
= $20 - $8.34 - $4.12
= $20 - $12.46
= $7.54
Hence, the amount left for gift c is $7.54

V (x) = (18 - 2x) (24-2x) (x)
what is a reasonable domain for V in this context?
Answer:
What are you asking?
Step-by-step explanation:
The domain of the given expression is all real numbers.
What is domain and range of the function?The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:
Domain = the set of all x-coordinates = {1, 2, 3, 4}
Range = the set of all y-coordinates = {2, 3}
The given function is v(x) =(18-2x)(24-2x)(x).
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
Interval Notation: (-∞, ∞)
Set-Builder Notation: {x|x∈R}
Therefore, the domain of the given expression is all real numbers.

Ella practices piano for 45 minutes she spends m minutes longer working on her homework than she does practicing the piano
Answer: See explanation
Step-by-step explanation:
Your question isn't complete but let's assume that you want to know the amount of time that she spends working on her homework.
Since we are informed that Ella practices piano for 45 minutes and that she spends m minutes longer working on her homework than she does practicing the piano, the expression to get the number of minutes that she uses on her homework will be:
= 45 + m
For example let's say that she spends 7 minutes more in her homework. Therefore, the total minutes spent on the homework will be:
= 45 + 7
= 52 minutes

Do 1/4 and 4/16 form a proportion
Answer:
There is a difference between FRACTION and PROPORTION.
Explanation of fraction:
On a card board sheet draw a square or rectangle or any simple shape of your choice. Divide your preferred shape into 4 equal parts. One portion or one part of the divided shape is 1/4. Three (3 ) parts of the divided shape equal 3/4. Also if the shape is divided into twenty (20). One (1) part is 1/20, sixteen(16) parts equal 16/20.
Explanation of Proportion:
If an item is shared in a proportion of 3:4,it means that A gets 3/(3+4) of what is to be shared , that is 3/7 of the bulk item to be shared. B gets 4/(3+4) of what is to be shared, that is 4/7 of the bulk item to be shared.
Also if an item is shared in a proportion of 16:20 , A gets 16/(16+20)=16/36 of Bulk item while B gets 20/(16+20)= 20/36 of the Bulk item being shared.
In effect Fractions and Proportions are related but different.

Find the seventh term of the geometric sequence 1, 2, 4, ... and the sum of the first seven terms. t7= S7=
Answer:
Seventh term is 64
Sum of the first seven terms is 127
Step-by-step explanation:
The common ratio is 2
[tex]a_{n} = a_{1} r^{n - 1}[/tex]
n = 7 and the first term is 1. So,
[tex]a_{7} = 1(2^{7 - 1} ) = 2^{6} = 64[/tex]
Seventh term is 64
[tex]S_{n} = \frac{a_{1} (r^{n} -1)}{r - 1}[/tex]
[tex]S_{7} = \frac{1(2^{7} -1)}{2 - 1}[/tex]
[tex]= \frac{128 - 1}{1} = 127[/tex]
Sum of the first seven terms is 127
