44 48 52 56 60 64 68 72 76 80 84 88 92 96 100
Answer:
30%
Step-by-step explanation:
% of change = 100 x (6.5-5)/ | 5 |
a. 6, 8, 10, 12, 14
Work:
a_1 = 2(1) + 4
a_1 = 6
a_2 = 2(2) + 4
a_2 = 8
a_3 = 2(3) + 4
a_3 = 10
a_4 = 2(4) + 4
a_4 = 12
a_5 = 2(5) + 4
a_5 = 14
b. 500
Work:
Since the common difference is 2, we can add 2 to each number until we reach the 20th term.
6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 + 22 + 24 + 26 + 28 + 30 + 32 + 34 + 36 + 38 + 40 + 42 + 44 = 500
Answer:
C) 960
Step-by-step explanation:
Let's expand the factorial.
n! = 1*2*3*4*...n
6! = 1*2*3*4*5*6
3!= 1*2*3
The given expression 
= 
Canceling out the common terms, we get
= 
= 8.4.5.6 [here . represents multiplication]
= 960
