A new car that sells for $18.000 depreciates at a rate of 25% per year. Find the value of the car after 4 years ?

Mathematics
1 answer:
Rom4ik [11]3 years ago
4 0

Answer:

After 4 years, the value of the car would be of $5695.31.

Step-by-step explanation:

The formula for compound interest works perfectly in this case:

a = p {(1 +  \frac{r}{n} )}^{nt}

As in this case the repetitions per annum are just 1 (yearly), we can ignore the n.

Replacing variables with our values, a yields the depreciated value:

a = 18000 {(1 - 0.25)}^{4}  \\ a = 18000 {(0.75)}^{4}  \\ a = 18000(0.31640625) \\ a = 5,695.3125 = 5695.31

Let f be defined as shown.<br> What is f^-1(1)?
FinnZ [79.3K]

Answer:

From the above image when the input of f(x) is 9 the output is 1

So f^-1(1) is just the reverse when the input is 1 the output is 9

So f^-1(1) = 9

Hope this helps

What side is the shortest in the picture?<br><br> A. GF<br> B. DG<br> C. EF<br> D. GE<br> F. DE
igor_vitrenko [27]

Answer:

A. GF

Step-by-step explanation:

The shortest side in a triangle is opposite the smallest angle

<d = 180 -52 -61 =67

The smallest angle is 52 so the smallest side is DG

<f = 180 - 48-85 =50

The smallest angle is 48 so the smallest side is FG

The smallest angle is 48 so the smallest side overall is FG (GF)

Find the value of m .​
kondor19780726 [428]

Step-by-step explanation:

if the 2 matrices are inverse, then their product must be the identity matrix

1 0

0 1

so,

m×3 + 2×-7 = 1

7×3 + 3×-7 = 0

m×-2 + 2×m = 0

7×-2 + 3×m = 1

that means we have to solve only

3m - 14 = 1

3m = 15

m = 5

Find the area of the shaded region for the given figure in terms of x.
Vlada [557]

Answer:

Area of the shaded region = (6x + 3)

Step-by-step explanation:

Area of the shaded region = Area of the large rectangle - Area of the small rectangle

Area of the large rectangle = Length × Width

                                             = (x + 2)(x + 2)

                                             = (x + 2)²

                                             = x² + 4x + 4

Area of the small rectangle = (x - 1)(x - 1)

                                             = (x - 1)²

                                             = x² - 2x + 1

Area of the shaded region  = (x² + 4x + 4) - (x² - 2x + 1)

                                             = 6x + 3

Area of the shaded region = (6x + 3)
