Answer:

Option 4

Step-by-step explanation:

Given : Geometric sequence a_n=20\times (\frac{1}{2})^{n-1}    

To find : Which spreadsheet would be used to compute the first 7 terms of the geometric sequence  ?

Solution :

Geometric sequence is in the form a+ar+ar^2+ar^3+...

Where, a is the first term and r is the common ratio.

The sum of sequence is represented as  S_n=\sum^{7}_{n=0} ar^n

or S_n=\sum^{7}_{n=1} ar^{n-1}

According to question,

a=20 and r=\frac{1}{2}

Sum of first terms is,

S_1=20(\frac{1}{2})^{n_1-1} , n_1=1

Sum of second terms is,

S_2=20(\frac{1}{2})^{n_2-1} ,n_2=2

Sum of third terms is,

S_3=20(\frac{1}{2})^{n_3-1} ,n_3=3

Sum of four terms is,

S_4=20(\frac{1}{2})^{n_4-1} ,n_4=4

Sum of five terms is,

S_5=20(\frac{1}{2})^{n_5-1} ,n_5=5

Sum of six terms is,

S_6=20(\frac{1}{2})^{n_6-1} ,n_6=6

Sum of seven terms is,

S_7=20(\frac{1}{2})^{n_7-1} ,n_7=7

Therefore, Option 4 is correct.

The spreadsheet 4 would be used to compute the first 7 terms of the geometric sequence.

​You need to wrap a present that you will put inside a cylindrical container. You’ll need to know how much will fit in the conta
nirvana33 [79]

Answer:

149.28 sq. inches

137.5 cubic inches.

Step-by-step explanation:

The cylindrical container has length or height (h) 7 inches and has a diameter of 5 inches i.e. radius (r) 2.5 inches.

Now, total surface area of the container = 2\pi r^{2} + 2\pi rh

= \frac{2 \times 22 \times (2.5)^{2} }{7} + \frac{2 \times 22 \times 2.5 \times 7}{7}

= 39.28 + 110  

= 149.28 sq. inches (Answer)

Again the volume of the container will be \pi r^{2}h

= \frac{22 \times (2.5)^{2} \times 7}{7}

= 137.5 cubic inches. (Answer)

The table shows the number of students in a class who play on a school team and/or are members of a school club:
eimsori [14]
This one is very simple.

create a simple equation to find out

15 = 12 + x

subtract 12 from each side

x= 3

the missing number is 3

or, to be even simpler, take the total, subtract the total from the number you know and the difference is the missing number.

hope I helped



ALSO, we can check going down vertically. 3 + 10 =13. this is the total listed at the bottom.
