Finding the value of x and y.
x:
sin 30 = 1/x
x = 1/sin 30
x = 2
y:
cos 30 = y/2
2(cos 30) = y
1.73 = y
Now the table:
sin 30 = 1/2
cos 30 = 1.73/2
tan 30 = 1/1.73
sin 60 = 1.73/2
cos 60 = 1/2
tan 60 = 1.73/1
Hope this helps :)
Answer:
6554
Step-by-step explanation:
The sequence 2, -8, 32, -128 has a first term (a1) of 2 and a common ratio (r) of -8/2 = -4. The sum of n terms is given by ...
Sn = a1·(r^n -1)/(r -1)
For your sequence, the sum of 7 terms is ...
S7 = 2·((-4)^7 -1)/(-4-1) = 2(-16384/-5) = 6554
The sum of changes after the 7th day is 6554.
Into 3 parts meand sivided by 3 means times 1/3
1/6 divided into 3 parts means 1/6 times 1/3=1/18
1/18 was in each mound
