Assuming the sequence goes on like this 11,-33,99,-297,891,...,
its general formula is

So, the 9th term is
Answer: yes it can be a measure of a triangle
I hoped i helped you and can i have brainliest if it's ok? ty
Sides: a = 6 b = 11 c = 13
Area: T = 32.863
Perimeter: p = 30
Semiperimeter: s = 15
Answer:
Approximately 76.5 mg.
Step-by-step explanation:
Given,
The initial quantity of the Bismuth-210, P = 233 mg,
Also, the rate of decay per day, r = 13 %
Thus, the quantity of the Bismuth-210 after 8 days would be,






Because of exterior angles theorem, y=39+65, so y=104
x and y are a linear pair, so they add up to 180. x=180-104, x=76
all angles in a triangle add up to 180, so 21+104+z=180. therefore, z=55
y=104
x=76
z=55
