The height of the tower roughly equals 41.421 meters.
Answer:
Given
f(x)=18,000(.88)^x
We need to find the value of x when f(x) <2000
2000 = 18000(0.88)^x
0.88^x 2000/18000
0.88^x 1/9
• x = log (1/9) / log (0.88)
• x= 17 (rounded down)
After 17 years or during year 18 the car value will drop below $2000
Alternate interior angles are:
(2x-70) = (x+30)
2x-x = 30+70
x = 100
the angle 5y is supplementary to the other angle.
5y + (100+30) = 180
5y + 130 = 180
5y = 180-130
5y = 50
y = 50/5
y = 10
