What is the sum of the geometric sequence 3, 15, 75, … if there are 8 terms?39,062

195,312
292,968

Answers

If you would like to know the sum of the geometric sequence, you can calculate this using the following steps:

3, 15, 75, 75 * 5 = 375, 375 * 5 = 1875, 1875 * 5 = 9375, 9375 * 5 = 46875, 46875 * 5 = 234375

3 + 15 + 75 + 375 + 1875 + 9375 + 46875 + 234375 = 292,968

The correct result would be 292,968.

Answer:

292,968

Step-by-step explanation:

Step 1: Use geometric sequence formula $s_n=(a1r^n)/(1-r)$

$S_n$ & $n$ = the sum of geometric sequence & terms in total (8)

$r$ = common ratio (5)

$a_1$ = first term in sequence (3)

$s_8=(3(5)^(^8^))/( 1-5 )\ns_8=((3)390625)/(-4)\ns_8= (1171875)/( -4 )\ns_8=292968$

The solution to 2 * 27 will be what kind of number?A. Prime
B. Odd
C. Perfect square
D. Even

Answers

Answer: Even

Step-by-step explanation:

The given product is $2*27$

When we solve the given product we get, $2*27=54$

Now, 54 is not a prime number since it has more than two factors such as 2 and 27.

[ ∵ A prime number is a whole number greater than 1 and it has only two factors which are 1 and itself. ]

It is even not odd since its last digit is an even number.

54 cannot be written as $n* n$ , for any natural number n, therefore, it is not a perfect square.

Answer: Hello mate!

Let's analyze the options:

A) prime, a prime number is a number that only can be divided by 1 and itself, if you look at the number 2*27, you can see that this number can be divided by 2 and 27, then this number is not prime.

B) An odd number has the form m= 2*n + 1 where n is an integer number.

in this case, we have 2*27, so this number is not odd.

C) perfect square, 2*27 = 54, we know that 7*7 = 49, and 8*8 = 65

so 2*27 lays in between two consecutive perfect squares, so 2*27 can not be a perfect square.

D) an even number has the form 2*n, where n is an integer.

n = 27 is this case, so 2*27 = 54 is an even number.

2.0 is ???? times greater than 0.02

Answers

2.0 is 100 times greater than 0.02. When you have two numbers that are just separated by zeroes, simply count the number of zeroes and multiply the smaller number by a multiple of ten with the same number of zeroes to get the larger number. For instance, if you were to have 40 and 0.0004, you can just count the number of decimal places between them (in this case 4), and put the same number of zeroes behind a 1 (10,000). Then, if you multiply 0.0004 by 10,000, you should get 40. Likewise, if you multiply 0.02 by 100, you should get 2.
