Answer:
7th term is -1
Step-by-step explanation:
Mathematically, we have the nth term of a geometric sequence as:
Tn = ar^(n-1)
where a is the first term
n is the number of terms
T4 = ar^3
64 = -4096 * r^3
r^3 = -64/4096
r^3 = -1/64
r^3 = (-1/4)^3
r = -1/4
The 7th term is:
T7 = ar^6
T7 = -4,096 * (-1/4)^6
T7 = -1
The 7th term is -1
Answer:
3. 10 - 5 is 5. so that is the difference. difference means subtraction.
4. 108 - 30 = 78. so she can move 78 degrees miore after therapy because 108 minues 30 is 78
5. 99 because 180 - 81 = 99. there is always 180 degrees in a line angle.
6. 130 degrees. 25 + 25 = 50 so 180 minus 50 equals 130
Step-by-step explanation:
9. (57)
10. 12/7 OR 1.714285
11. 207
12. 8
13. 7/2 OR 3.5
14. -15/16 OR -0.9375
15. 12x - 7
16. -9m - 25
17. -9w + 56
18. 12x - 8y
19. -5a + 15b
20. -11xy +8x -6
IF YOU NEED THE WORK FOR ANY FEEL FREE TO ASK BUT ALL I DID WAS PLUG IN VALUES AND/OR DISTRIBUTE
hope this helps you :)
C because twice the difference of a number and 5
2 (n-5)
or it can be wrtten as 2(x-5)
