I WILL MARK BRAINLIEST Since 2006, the amount of money spent at restaurants in a certain country has increased at a rate of 5% each year. In 2006, about $410 billion was spent at restaurants.
If the trend continues, about how much will be spent at restaurants in 2020?
(round to the nearest whole number as needed. Thankyou!!!

Hi,

between 2006 and  2020 there is  13 years. As the increase start in 2007

so :  410*1.05^13 ≈773,11

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
