Answer:
The sun of the infinite geometric series is 468
Step-by-step explanation:
The sum of an infinite geometric series is given by;
where a=156 is the first term and
is the common ratio.
We substitute these values into the above formula to get:
Answer:
Step-by-step explanation:
Part a is AB and CD because those lines are symmetrical.
Part D is the angle is the same as A so D is 30 as well. then for b and c since those are the same you take 180-30 to get 150 for both angles
Answer:
(0, -23)
Step-by-step explanation:
the slope is -12/18 or -2/3 in reduced form
i used the point (-36,1) and -2/3 as the slope to find 'b' (the y-intercept):
y = mx + b
1 = -2/3(-36) + b
1 = 72/3 + b
1 = 24 + b
-23 = b
Answer: 15.72575
Step-by-step explanation:
Divide 250 over:
40/250=(0.89)^x
Log both sides (easiest with graphing calculator)
Remember exponent comes down in front on a log
Log(0.16) = x log (0.89)
X= Log (.16) / log (0.89)
