A boat costs $12,050 and decreases in value by 12% per year. How much will the boat be worth after 9 years?A $33,415.60
B $3,813.56
C $11,942.00
D $3,355.94

Answers

Answer 1

Answer: B $3,813.56 is the correct answer

1 year = $10,604
2 years = $9,331.52
3 years = $8,211.74
4 years = $7,226.33
5 years = $6,359.17
6 years = $5,596.07
7 years = $4,924.54
8 years = $4,333.60
9 years = $3,813.56

Answer 2

Answer:

For this case we have the following expression:

$y = A (b) ^ x$

Where,

A: initial value
b: rate of change
x: number of years
y: future value

Therefore, replacing values we have:

$y = 12050 * (0.88) ^ 9\ny = 3813.56$

Answer:

The boat will be worth after 9 years about:

B $ 3,813.56

What is the inverse f(x)= 2x+1

Answers

Answer:

f^-1(x) = (x - 1)/2

Step-by-step explanation:

f(x) = 2x + 1

y = 2x + 1

x = 2y + 1

2y + 1 = x

2y = x - 1

y = (x - 1)/2

f^-1(x) = (x - 1)/2

The diagram shows a patio in the shape of a rectangle.The patio is 3.6m long and 3m wide.

Mathew is going to cover the patio with paving slabs. Each paving slab is a square of side 60cm.

Mathew buys 32 of the paving slabs.

A) Does Mathew buy enough paving slabs to cover the patio?

The paving slabs cost £8.63 each

B) Work out the total cost of the 32 paving slabs.

Answers

if Mathew has bought 32 slabs , he has enough paving slabs to cover the patio and £276.16 is the total cost of the 32 paving slabs.

What is a Rectangle ?

A rectangle is a polygon with 4 sides , in which opposite sides are parallel and equal .

It is given that the patio has length of 3.6 m and width of 3 m

Each paving slab is a square having side 60 cm or .6 m

Area of a rectangle is given by

length * width

3.6*3

10.8 m²

Area = 10.8 m²

Area of a slab = 0.6 *0.6 = 0.36 m²

No. of slabs needed = n

10.8 = 0.36* n

n = 30 slabs

So if Mathew has bought 32 slabs , he has enough paving slabs to cover the patio.

If the paving cost costs £8.63

The total cost for 32 slabs will be 32 * £8.63

= £276.16
