Answer:
$13,793
Step-by-step explanation:
Kate purchased a car for $23,000. It will depreciate by a rate of 12% a year. What is the value of the car in 4 years. *
The formula for Depreciation rate =
y = a(1 - r) ^t
Where
y = Value of the car after t years
a = Initial value of the car = $23,000
t= time in years = 4 years
r = Depreciation rate = 12% = 0.12)
y = $23000 (1 - 0.12)⁴
y = $13792.99328
Approximately = $13,793:
Answer:
a) 1/800 or 0.00125
b) i) 0.0013
ii) 0.001
c) 60%
Step-by-step explanation:
T = [tan(2×30)+1][2cos(30)-1] ÷ (y²-x²)
T = (tan60 + 1)(2cos30 - 1) ÷ (41² - 9²)
T = (sqrt(3) + 1)(sqrt(3) - 1) ÷ 1600
T = (3-1)/1600
T = 2/1600
T = 1/800
T = 0.00125
Error: 0.002 - 0.00125
0.00075
%error
0.00075/0.00125 × 100
60%
Answer:
49 square feet
Step-by-step explanation:
Area of square
![= {7}^{2} \\ \\ = 49 \: {ft}^{2} \\](https://tex.z-dn.net/?f=%20%3D%20%20%7B7%7D%5E%7B2%7D%20%20%5C%5C%20%20%5C%5C%20%20%3D%2049%20%5C%3A%20%20%7Bft%7D%5E%7B2%7D%20%20%5C%5C%20)
Because we are dealing with area, we have to square the difference of the 2 polygons.40 / 15 =

Step-by-step explanation:
x=(180-x)-172
x+x=180-172
2x=8
x=4(angle)
180-4=176(supplementary angle)
