15 because simple division 30 divided by 2 is 15 only 15 can happen
The sum if the geometric sequence given by:
an=-2(3)^(n-1)
will be:
when:
n=1
an=-2
when n=2
a2=-6
when n=3
a3=-18
when n=4
a4=-54
when n=5
a5=-162
when n=6
a6=-486
when n=7
a7=-1458
when n=8
a8=-4374
thus the summation of the term will be:
Sn=(-4374+-1458+-486+-162+-54+-18+-6+-2)
Sn=-6560
the answer is -6560
Answer:
Step-by-step explanation:
The given expression is
The tangent of -1 is defined, it's around -0.02.
The tangent is a trigonometric function with a period of 
, where each period is separated by a vertical asymptote which indicates that the function is not determined through all its domain, that's what the question refers to when it says "if is undefined, enter undefined".
However, at 
, the tangent is determined, that means, there's no asymptote on that coordinate, that's why it has a "determined value", which is -0.02 approximately.
Answer:
a = 36
Step-by-step explanation:
We use pythagoras theorem here.
h = 60
p = 48
b = a
h² = p² + b²
60² = 48² + b²
3600 = 2304 + b²
b² = 3600 - 2304
b² = 1296
b = 36
Answer:
8
Step-by-step explanation:
The 110 degree angle is oppoiste to the angle across it.
Using PLT-C the other angle on the bottom of it should be 70 degrees.
since the 70 degrees is on a straight angle the angle beside it should 110
14(8)-2 = 110
