One model for car depreciation is as follows, where Cis the original cost, Vis the value of the car after tyears, and ris the rate
of depreciation
V= (1-1)
If the original cost of the car was $21,000 and the rate of depreciation is 15%, what will be the value of the car after 5 years?
[Round to the nearest dollar.]
A. $17,850
B. $3,150
C. $9,318
D. $19,472
Given:
Original cost of car = $21000
Rate of depreciation = 15% = 0.15
Time = 5 years
To find:
The value of car after 5 years.
Solution:
Consider the model for car depreciation is
[tex]V=C(1-r)^t[/tex]
where, C is the original cost, V is the value of the car after t years, and r is the rate of depreciation.
Substitute C=21000, r=0.15 and t=5 in the above model.
[tex]V=21000(1-0.15)^5[/tex]
[tex]V=21000(0.85)^5[/tex]
[tex]V=21000(0.4437)[/tex]
[tex]V=9317.7[/tex]
[tex]V\approx 9318[/tex]
The value of car after 5 years is $9318. Therefore, the correct option is C.

A car has an initial value of $20,000. The value then "depreciates" or decreases by 10% of its initial value each year. Which equation below gives the value of the car, v, after y years?
v = -2,000 y + 20,000
v = 0.10 y - 2,000
v = 2,000 y - 20,000
v = - 0.10 y + 2,000

A family built a house in a beach resort area. In 1990, the house was 430 ft from the water. With erosion, the house was 400 ft from the water in 2000. In what year will the house be only 250 ft from the water?
a. 1990
c. 2015
b. 2004
d. 2050
We develop an equation for the given situation by first writing the general equation for lines,
y = mx + b
Substituting to this given the values given above,
(1990) 430 = b
(2000) 400 = m(10) + 430
The value of m from the equation in 2000 is -3. Thus, the equation of that relates the variables is,
y = -3x + 430

d. 2050

The required solutions are given as,
13) Discounted price of the walled 0.61 cents,
14) the sale price is given as $ 13.78,
15) sale price of the wallet is $ 3.82,
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,

The perfect wallet is on sale for 89% off its original $5.62 price,
Discounted price, = 5.62 - 89% of 5.62
= 5.62 - 0.89 × 5.62
= 5.62(1 - 0.89)
= 5.62(0.11)
= 0.61 cents
Similarly,
14) the sale price is given as $ 13.78,
15) sale price of the wallet is $ 3.82,

(x^(3-6))^2 = (x^-3)^2
x^3*2+x^-6*2 = x^6+x^-12
when the numbers are just next to each other (ex. x²x³) you just ADD the exponents and you get (in this case x^6)when the numbers and exponents are in and out of parentheses (ex. (x³)²) you MULTIPLY the exponents (in this case you get x^6)when you have both, you solve what is IN the parentheses (ex. (x²x³)²) first, making the equation (ex. (x^6)²) and then you multiply the exponent by 2 (ex. (x^12) and get the answer. NOTE - ^ means to the powerThe second from the top, and the second to last expressions should be the answer

9 hundreds equals how many tens
Answer:
90 tens
Step-by-step explanation:
900 = 10x
Variable x refers to how many 10's are needed to equal 900
To solve for this, divide both sides of the equation by 10
900 ÷ 10 = 10x ÷ 10
90 = 1x
90 = x
It will take 90 tens to equal 900

Evaluate 4(3-1)² i need help with this
Answer:
16
Step-by-step explanation:
You can use PEMDAS to answer this question.
So first you would do whats inside the parenthesis.
4(3-1)².
3-1 is 2 so 2 would be in the parenthesis. Next you have to do exponets.
4(2)².
2² is 4. So now you just have a multiplication problem left.
4(4) which is 16.

When we evaluate the quotient functions, (mn)(x) for x = -3
(mn)(-3) = 9 and (m/n) (x), x ≠ 0
How did we evaluate the quotient function?To evaluate the quotient function (mn)(x) for x = -3, we substituting x = -3 into the function mn(x).
This gives us (mn)(-3) = m(-3) × n(-3) = (-3)² × (-3) = 9.
We then need to evaluate (m/n)(x), x ≠ 0.
This is done by dividing the function m(x) by the function n(x). This gives us (m/n)(x) = m(x) / n(x) = x^2 / x = x. However, this expression is undefined when x = 0, because division by zero is undefine

How to calculate unit price of something?Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.
Thus, unit price of something is price of 1 thing.
Then suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.
WE have been given a recipe for ice cream calls for 56 fluid ounces of milk.
We need to find How many pints of milk are there in the recipe.
There are 16 fluid ounces in 1 pint then;
56 ÷ 16
= 3.5
The answer is 3.5 pints because there are 16 fluid ounces in one pint which means that there are two pints in 32 fluid ounces and 3.5 pints in 56 fluid ounce.
