We get tne n-th term with: tn=1/3tn-1
We know that the first term is t1=81, so 81=1/3t*1-1
81=1/3t-1
82=1/3t
82*3t=1
3t=1/82
t=1/82*3=1/246
The second term is: 1/
2*(1/246)*2)-1
We get the third term by replacing n with 3 and so on...
x and y i think, I haven't done that in a long time.
Because 42 doesn't go into 63, you have to go larger. Start by multiplying 63 by 2.
63*2=126
42 goes into 126 3 times even, so the LCM of 42 and 63 is 126 :)
Answer:
1436.75504 or 1372/3π cm^3
Step-by-step explanation:
The volume of a sphere can be found using:
V = 4/3 πr^3
We know the radius is 7, so we can substitute 7 in for r
V = 4/3 π7^3
Evaluate the exponent
V = 4/3 π 343
If we want the answer in terms of pi, multiply the two other numbers, that are not pi: 4/3 and 343.
v= (4/3*343)π
v=1372/3π
If we want an exact answer, multiply 1372/3 and pi
v=1436.75504
So, the volume is 1436.75504 or 1372/3 π cm^3
Answer:
It depends
Step-by-step explanation:
If it is in the first quadrant the reference angle is the standard angle, if it is the second quadrant subtract by 180, if it is in the third quadrant use the terminal angle - 180 and the fourth quadrant subtract by 360
