Answer:
Step-by-step explanation:
√x - 7 = 3 {add 7 to bothe sides}
√x - 7 + 7 = 3 + 7
√x + 0 = 10
√x = 10
Square both sides,
(√x)² = 10²
x = 100

0.00692
a formula for the general term a n of the sequence assuming the pattern of the first few terms continues. { − 13/3 , 16/9 , − 19/27 , 22/81 , − 25/243 , ... } is .
<u>Step-by-step explanation:</u>
Here we have , the pattern of the first few terms continues. { − 13/3 , 16/9 , − 19/27 , 22/81 , − 25/243 , ... } . We need to find a formula for the general term a n of the sequence . Let's find out:
In this question there is no such technique , instead we have to use our brain to manipulate the pattern as :
1st term = − 13/3 =
2nd term = 16/9 =
3rd term = − 19/27 =
4th term = 22/81 =
5th term = − 25/243 =
nth term =
Therefore, a formula for the general term a n of the sequence assuming the pattern of the first few terms continues. { − 13/3 , 16/9 , − 19/27 , 22/81 , − 25/243 , ... } is .
The answer to this problem is a
Answer:
25/28
Step-by-step explanation:
make the denominator to 28 by doing 4 x 7
3 /4 x 7 = 21/28
1/ 7 x 4 = 4/28
21/28 + 4/28 = 25/28
