What is the length of CD in this diagram, ABC - EDC,

natima [27]

Answer:

Option A is the right option.

solution,

∆ABC~∆EDC

$\frac{bc}{cd} = \frac{ac}{ec} \\ \:$

putting the values,

$\frac{20 - x}{x} = \frac{20}{5} \\ or \: 5(20 - x) = 20x(cross \: multiplication) \\ or \: 100 - 5x = 20x \\ or \: - 5x - 20x = - 100 \\ or \: \: - 25x = - 100 \\ \: or \: x = \frac{ - 100}{ - 25} \\ x = 4$

Hope this helps..

Good luck on your assignment..

In the year 2006, a person bought a new car for $18000. For each consecutive year after that, the value of the car depreciated b

Liula [17]

Answer:

Step-by-step explanation:

Use the exponential function

$v(t)=a(b)^t$ where a is the initial value of the car, b is the rate of decay, and t is the time in years. For us, a = 18000, b = (1 - .15), so the model for this car is:

$v(t)=18000(.85)^t$ We can use this model now to find the value, v(t), of the car after 3 years has gone by (from 2006 to 2009 is 3 years):

$v(t)=18000(.85)^3$ and simplifying a bit:

v(t) = 18000(.614125) so

v(t) = 11054.25

Round however you need to.
