Answer:
The year is 2020.
Step-by-step explanation:
Let the number of years passed since 2010 to reach population more than 7000000 be 'x'.
Given:
Initial population is,
Growth rate is,
Final population is,
A population growth is an exponential growth and is modeled by the following function:
Taking log on both sides, we get:
Plug in all the given values and solve for 'x'.
So, for , the population is over 700,000. Therefore, from the tenth year after 2010, the population will be over 700,000.
Therefore, the tenth year after 2010 is 2020.

Answer:
7 1/24
Step-by-step explanation:
First, you have to get the fractions to have the same denominator. So, you take 2/3 and 3/8 and find the smallest number by multiplying for the denominator. That number is 24 because 3 times 8 is 24 and 8 times 3 is 24.
Then, you multiply both the denominator and the numerator by the number that you got for the fractions. 2 * 8 = 16 3 * 8 = 24. 3 * 3 = 9 8 * 3 = 24. So, that gives you 16/24 and 9/24. Now since they have the same denominator you can add them.
This gives you 25/24 which equals 1 1/24.
Next, you can add the whole numbers. That is 6.
Lastly, take your fraction answer and your whole number answer and you get 7 1/24.
I hope this helps! =)
Answer:
x=3
Step-by-step explanation:
Answer: y= -1
Step-by-step explanation:
Add 5 to both sides,
y-5+5=-9y-15+5
Simplify,
y=-9y-10
Add 9y to both sides,
y+9y=-9y-10+9y
Simplify,
10y=-10
Divide both sides by ten.
10y over 10 = -10 over 10
There you go!
