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.
The two variables are time (x) and distance (y)
And the answer is they will meet after 1 mile
The function of the aunt and uncle is y=25x+5
The function of yourself is y2=30x
Since you want to know when you’ll meet, you just resolve y=y2 or 25x+5=30x
Wich will be x=1 so 1 mile
Answer:
(x-10)(x+10)
Step-by-step explanation:
x^2 – 100
This is the difference of squares
x^2 - 10^2
We know that (a^2 - b^2) = (a-b) (a+b)
(x-10)(x+10)
Answer:
Step-by-step explanation:u have to add x+6 = ur answer there u go
