With the help of the given equation, we know that the automobile is worth $12528.15 after four years.
<h3>
What are equations?</h3>
- A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.
- a formula that expresses the connection between two expressions on each side of a sign.
- Typically, it has a single variable and an equal sign.
- Like this: 2x - 4 Equals 2.
- In the above example, the variable x exists.
So, the equation of depreciation: y = A(1 - r)∧t
The current value is y.
A is the initial cost.
r is the depreciation rate.
t is the time in years, and
In four years, we must ascertain the present value.
Now,
y = $24000(1 - 0.15)⁴
y = 24000(0.85)⁴
y = 24000 × 0.52200625
y = 12528.15
Therefore, with the help of the given equation, we know that the automobile is worth $12528.15 after four years.

Complete question:
The general equation for depreciation is given by y = A(1 – r)t, where y = current value, A = original cost, r = rate of depreciation, and t = time, in years. The original value of a car is $24,000. It depreciates 15% annually. What is its value in 4 years? $
Answer:
9 %
Step-by-step explanation:
What % is 773.10 of $8,590?
X/100 = 773.10/8590 (x/100=is/of)
(733.10 * 100) / 8590
= 9
Answer:
108° = 
radians
Step-by-step explanation:
To convert from degrees to radians
radians = degree measure × 
, thus
radian measure = 108° × =
Answer:
Step-by-step explanation:
d = r * t
Let the rate of the boat in still water = x
Let the rate of the stream = y
Against the current
24 = (x - y)* 4 Divide both sides by 4
24/4 = x - y
6 = x - y
With the current
24 = (x + y )* 3 Divide both sides by 3
24/3 = (x + y)
8 = x + y
Put the two equations together
x - y = 6
<u>x + y = 8</u> Add
2x = 14 Divide by 2
2x/2 = 14/2
x = 7
x + y = 8
7 + y = 8
y = 8 - 7
y = 1
The boat is going 7 miles per hour
The stream is going 1 mile per hour.
Use the formula sin A/ side a = sin B/side b. sin 12/8=sin B/10. Now cross-multiply, and with your calculator in degree mode, 10 sin 12 = 8 sin B. The left side comes out to 2.079, so you need to divide both sides by 8 to get sin B alone. Now the equation is .2599=sin B. Use the inverse function on your calculator sin^-1(.2599)=15.06
