Answer:
y = √(3² + 3²)
9 = √(5² + x²)
Step-by-step explanation:
Diagram 1:
Hypotenuse = y
Opposite = 3
Adjacent = 3
y² = 3² + 3²
y = √(3² + 3²)
y = √(9 + 9)
y = √18
Diagram 2:
Hypotenuse ² = known leg² + unknown leg²
Hypotenuse = 9
Known leg = 5
Unknown leg = x
9² = 5² + x²
9 = √(5² + x²)
9² = 5² + x²
9² - 5² = x²
x² = 81 - 25
x = √ 56
The value of x is x=1/10
This can also be written as:
X=0.1
X=10^-1
Answer:
$15 827
Step-by-step explanation:
The formula for the amount A of depreciation of an asset by an annual percentage rate is
A = V(1 - r)ⁿ
where
n = number of years
r = annual percentage rate
V = value
Data:
n = 13 yr
r = 9 %
V = $22 400
Calculations:
A = 22 400(1 - 0.09)¹³ =22 400(0.91)¹³ = 22 400 × 0.293 45 = $ 6573
So, the car lost $6573 in value because of depreciation.
Current value = 22 400 - 6573 = $15 827
The answer is either 4 or 2
