Answer:
37 degrees
Step-by-step explanation:
As XW and YZ are parallel lines, you can use the co-interior angle rule to solve for x.
This is when you see a C-shape between parallel lines. The rule states that the sum of these two co-interior angles is 180 degrees.
Therefore,
⇒
⇒ [collect like terms of x]
⇒ [add 5 to both sides]
⇒ [divide both sides by 5]

Answer:
a)
b) 6.84 million
c) 2028.52
d) 47 years
Step-by-step explanation:
a)Here we know standard exponential growth rate is
In this put t=0 and a(t)=6.27 million
thus we get a = 6.27 million
now
this is equal to(in 2012)=
b)Put t = 6
we get
=6.84 million
c)
take log both sides
we get 16.52 years
d)
take log both sides we get 47 years to get double the current population.
