Area of wall = 9 * 12 = 108 ft^2 Width of TV = x Lenght = 2x Diagonal of TV = 72 " = 6 ft
x^2+(2x)^2=6^2 x^2+4x^2=36 5x^2=35 x^2=36/5 x=sqrt(36/5) Width = 2.68 ft. Length = 2.68 * 5.36 = 14.36 ft^2 Area of wall - area of tv = 108 - 14.36 = 93.64 ft
Hi!!!, i used to be home schooled. IT WAS THE WORST. I've had to go through what your going through right now for 2 years. I'm in the 8'th grade. and i've been wanting to meet new friends.
After every month's withdrawals, 4/5 of the original amount at the start of the month will remain. The amount at the start of every month will change. Thus: an = 4/5 (an-1) ; where a1 = 500.
