Hamish buys a new car for 520000
The car depreciates in value by 19% each year.
Work out the value of the car at the end of 3 years.
Give your answer to the nearest $.

Answers

Answer:

$223,600

Step-by-step explanation:

1. Multiply 520000 by 0.19 and get an answer of 98800. This is how much by which the car depreciates every year.

2. Now multiply 98800 by 3 (years). Now your answer would be 296400.

3. Now minus the depreciated value from the original value which is 520000-296400=223600.

Not sure about the answer but I hope this helped a bit

Answer:

$3,567.00

Step-by-step explanation:

Here is how I got it!

First, you will have to borrow the 520,000 from the word problem.

Next, multiply 520,000 with 0.19 with the power of 3

[tex]520,000*0.19^3=n[/tex]

The 3 is the number of years, n is the nearest $ answer.

First, do [tex]0.19^3[/tex]

[tex]0.19*0.19*0.19=0.006859[/tex]

(Again, that's a crazy number!)

With 0.006859, multiply it with 520,000

[tex]520,000*0.006859=3566.68[/tex]

3566.68 is technically (in money) $3,566.68 (with .68 being sixty-eight cents).

Finally, it states to answer to the nearest $.

Just round up the .68 to 1 dollar which will just add one more dollar to 3,566

[tex]3,566.32[/tex] ⇒ [tex]3,567.00[/tex] (since .32 is below .50, you can't round it UP)

Add you $ symbol

With the result being: $3,567.00

F(x) =2x-1 what is the value of f(x) when x = -1

Answers

Answer:

f(x) = -3 when x = -1

Step-by-step explanation:

Let's go through this!

So our equation is f(x) = 2x - 1

we are asked for the value of f(x) when x = -1

Let's consider this, the f(x) value is the y value

and the x value in f(x) is the x value

So when x = -1

what is the y value?

we can use the equation to subsitute -1 into x and solve for f(x)

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

f(x) = -3

Our answer is -3

Answer:

The solution is A. (-2,7) and C. (3,2)

Step-by-step explanation:

x+y = 5 ............(1)

x²+y = 11 ............(2)

_________________________

y = 5-x

x²+(5-x) = 11

x²+5-x-11 = 0

x²-x-6 = 0

x²+2x-3x-6 = 0

(factor statement)

x(x+2)-3(x+2) = 0

(x+2) (x-3) = 0

x+2=0 x-3 =0

x = -2 x = 3

(x1 = -2, x2 = 3)

_________________________

y = 5-x

y = 5-(-2) ............(1)

= 7

y = 5-3 ............(2)

= 2

(y1 = 7, y2 = 2)

_________________________

(x1,y1) & (x2,y2)

(-2,7) & (3,2)

So, A. (-2,7) and C. (3,2) correct

Two numbers multiply to be -40 and add to be 3. What are the numbers?

Answers

Answer:

The numbers are (x,y)=(-5,8) or (8,-5)

Step-by-step explanation:

Let two numbers be x and y,

We have,

x+y=3

x=3-y---(i)

Now,

xy=-40

(3-y)y=-40 [From (i)]

3y-y^2=-40

y^2-3y-40=0

Factoring,

(y + 5) (y - 8)=0

Either,

y+5=0 or, y-8=0

y=-5 y=8

When y=-5,

x=3-y

3--5

3+5

When y=8,

x=3-y

The length of a rectangle is four times its width.
If the perimeter of the rectangle is 70 ft, find its length and width.

Answers

Let L represent length of rectangle

Let W represent width of rectangle

L=4W

2L+2W=70

Substitute 4W for L

2(4W)+2W=70

8W+2W=70

10W=70

Divide both sides by 10

W=7

Use equation from beginning

L=4(7)

L=28

Width is 7 ft, length is 28 ft

Check work

2(28)+2(7)=70

56+14=70

70=70

In the diagram, line l is parallel to line m and is cut by transversal n. The measure of angle one is equal to 3x+6 and angle two measures 6(x−2).
What is the measure of angle one?

Answers

Answer:

Step-by-step explanation:

Since the lines L and M are parallel:

Angle 1 and and 2 are alternate and their measurement is equal.

3x + 6 = 6x - 12 (we multiplied 6 with inside the parenthesis)

6 + 12 = 6x - 3x

18 = 3x divide both sides by 3

6 = x to find the angle measure replace x with 6

3x + 6 is 3*6 + 6 = 24

let f(x)=-2x-7 and g(x)=-4x+3 find (f°g)(-5)

Answers

Answer:

-53

Step-by-step explanation:

f°g = f(g(x)) Remember this because this notation is less confusing for you.

Step 1. Plug g(x) in all values of x in the function f(x).

f(g(x)) = -2(-4x+3) -7

Step 2. Distribute the -2

-2(-4x+3) = 8x -6

f(g(x)) = 8x-6-7

Step 3. Simplify by subtracting -6 - 7

f(g(x)) = 8x-13

Step 4. Plug in -5 for x

8(-5) - 13 = -40 - 13 = -53

Answer:

9x-y = 5

Step-by-step explanation:

Equation of line in slope intercept form:

y-y1 = m*(x-x1), m=9, (x1,y1)=(4,31)

y-31 = 9*(x-4)

y-31 = 9x-36

9x-y = 36-31

9x-y = 5

11. There are a total of 30 puzzle pieces. Three
out of 5 are red, the remaining are black. How
many puzzle pieces are black?

Answers

Answer: 2

Step-by-step explanation:

5-3=2

30-5=15

If three out of the five are red and there are a total of 30 puzzle pieces then the number of black puzzle pieces will be 12.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.

it is given that there are a total of 30 puzzle pieces three out of 5 are red, and the remaining are black.

From the given condition,

(3/5) of total puzzle pieces = Number of red puzzle pieces

(3/5) × 30 = Number of red puzzle pieces

Number of red puzzle pieces = 18

Total puzzle pieces = Red puzzle pieces + Black puzzle pieces

30 = 18 + Black puzzle pieces

Black puzzle pieces = 30-18

Black puzzle pieces =12

Thus, if three out of the five are red and there are a total of 30 puzzle pieces then the number of black puzzle pieces will be 12.
