4x = 2π when x = π/2
The period is π/2.
Answer: 1145 feets
Step-by-step explanation:
The total feet of streamer that Shirley have to decorate with will be the addition of the total roll of blue streamer plus the total roll of green streamer. This will be:
= 5(93) + 8(85)
= 465 feet + 680 feet
= 1145 feets of streamer.
is 93 feet long and each roll of
Answer:
80
Step-by-step explanation:
70 + 30 = 100
180 - 100 = 80
Answer:
Yes . Divide by 10 for 10/20 to get 1/2.
10/10= 1
20/10= 2
10/20= 1/2
Answer:
Option b is correct 175
Step-by-step explanation:
n = 7
k = 6
3k -2 ------1
put k = 6 in above eq. for finding first term
a1 = 3(6) - 2 = 18 - 2 = 16
put k = 7 in above eq. for finding first term
a2 = 3(7) - 2 = 21 - 2 = 19
a3 = 3 (8) - 2 = 24 - 2 = 22
16, 19 , 22, ... //Arithmetic series formation
a1 = 16 , a2 = 19
d = a2 - a1 = 19 - 16 = 3 //Difference of first two terms
Using sum forumula for arithmetic series
sum =

=
= 7 * 25
= 175
