Hi there
First find the growth rate
P=Ae^kt
P 76 million
A 72 million
K ?
T time1,998−1,992=6 years
We need to solve for k
K=(log (p/A)÷log (e))÷t
So
K=(log(76÷72)÷log(e))÷6
K=0.009
Now find population in 2012
P=Ae^kt
Where
P ?
A 72 million
K 0.009
T 2,012−1,992=20 years
So
P=72×e^(0.009×20)
P=86.2 million round your answer to get 86 million
Hope it helps
Yes, both are congruent. The longest sides have the little mark indicating they are congruent.
Also, the two right angles correspond and are congruent as well.
I hope that helps!
Answer:
-70 -2

Answer:
Step-by-step explanation:
9/4x + 2 = 20
To get x by it's self you do the same on both sides of the = to cancel out each side.
9/4x + 2 = 20
(Multiply 9 on both sides)
4x + 2 = 20*9
(Now subtract 2 from both sides)
4x = 20*9 - 2
And finally divide both sides by 4
x = (20*9 - 2)/4
Then solve for x as normal.
