In ΔBCD, the measure of ∠D=90°, the measure of ∠C=83°, and DB= 1.3feet. What is the length of CD to the nearest tenth of a foot.
Lina20 [59]

Answer:

CD\approx0.2

Step-by-step explanation:

By the tangent ratio, tanC=\frac{DB}{CD}. Substituting the given values into this equation gives us:

tan83° = \frac{1.3}{CD}

CD*tan83° =1.3 (Multiply both sides of the equation by CD)

CD=\frac{1.3}{tan83\textdegree} (Divide both sides of the equation by tan83\textdegree)

CD=0.15962\approx0.2

Hope this helps!

Riley buys office equipment with a total price of $6,280 for her new company. If the office equipment depreciates at a rate of 1
alexdok [17]

Answer: y = 6280(0.87)^x

Step-by-step explanation:

If the office equipment depreciates at a rate of 13% each year, then the rate of depreciation is exponential.

We would apply the formula for exponential decay which is expressed as

y = b(1 - r)^x

Where

y represents the value of the office equipment after t years.

x represents the number of years.

b represents the initial value of the office equipment.

r represents rate of decay.

From the information given,

y = $628

r = 13% = 13/100 = 0.13

Therefore, the equation that represents the value of the equipment after x years is

y = 6280(1 - 0.13)^x

y = 6280(0.87)^x
