Answer:
40ft
Step-by-step explanation:
10x8= 80
80/2= 40ft
(-2,0)(-4, 4)
slope = (4 - 0) / (-4 +2) = -2
equation
y - 0 = -2(x + 2)
y = -2x - 4
answer
y = -2x - 4

Every year, the price of the smartphone is the of the price of the previous year (since we lose the , we remain with the ).
Since can be written as , the price after one year will be
After two years, the price is the of the price after one year:
And so on: after three years we have
So, the answer is somewhere between three and four years.
X axis : -t1 cos 60 + t2 cos 60 = 0
t2 cos 60 = t1 cos 60 ; t2 = t1
Y axis : t1 sin 60 + t2 sin 60 - 150 = 0
since t2 = t1
2t1 sin 60 = 150
t1 ( sqrt(3)/2) = 150/2
t1 = 50 [sqrt(3)]
t2 = 50 [sqrt(3)]
t3 = 150 N
