Answer: B
Step-by-step explanation:
![\dfrac{10x+8}{2} =5x+4\ cross\ products\\\\10x+8=10x+8\\\\0x=0\\](https://tex.z-dn.net/?f=%5Cdfrac%7B10x%2B8%7D%7B2%7D%20%3D5x%2B4%5C%20cross%5C%20products%5C%5C%5C%5C10x%2B8%3D10x%2B8%5C%5C%5C%5C0x%3D0%5C%5C)
Every real is solution of the equation .
The pythagorean theorem equation is a^2 (a squared) + b^2 (b squared) = c^2 (c squared)
so a^2+b^2=c^2
The correct answer is: 6.99 billion (as 6.986 billion is rounded off (to nearest hundredth place) to 6.99 billion)
Explanation:
The given function is: <span>y = 6.2(1.01)^x --- (1)
Where x = </span><span> number of years after 2000
It means that in 2012, the value of x would be 12 as the difference between 2012 and 2000 is 12 years.
Put x = 12 in equation (1):
(1) => y = </span>6.2(1.01)^12 = 6.986 billion = 6.99 billion
