Answer
one answer can be x = 30
Step-by-step explanation:
triangle needs to be 180 so if xy are the shortest they can be equal so z can be 120

Answer:
a = h-7
Step-by-step explanation:
h = a+7

Answer:
The series 64, 16, 4, 1 is convergent.
Step-by-step explanation:
Let be 
the set of values of the series. A series is convergent if and only if:
(1)
If we know that 
, 
, 
and 
, then the convergence ratio of each pair of consecutive values are, respectively:
, 
, 
Hence, the series 64, 16, 4, 1 is convergent.
Answer:
n(t) = 11e^0.019t
Step-by-step explanation:
The estimated population in 2010 = 11,000,000 = initial population
The growth rate = 1.9% per year = 1.9/100 =
The exponential growth model follows the general form :
n(t) = ae^rt
a = Initial population ; r = growth rate ; t = period
Hence, we have ;
n(t) = 11e^0.019t in millions
