Hailey purchased a new car in 2000 for $29,600. The value of the car has been depreciating exponentially at a constant rate. If the value of the car was $12,000 in the year 2007, then what would be the predicted value of the car in the year 2012, to the nearest dollar?

Answers

Answer:   $6297

=========================================================

Explanation:

x = number of years since the year 2000

eg: x = 1 represents the year 2001

y = value of the car in dollars

The point (x,y) = (0,29600) is on the curve and it's the y intercept. This is when Hailey bought the car with a value of $29600.

Another point on this curve is (7,12000) to indicate seven years have passed and the car is now worth $12000.

------------------------------

Since the y intercept is 29600, this is the value of 'a' in the equation

y = a*b^x

Meaning we can update it to

y = 29600*b^x

Plug in the coordinates of the other point so we can solve for b

y = 29600*b^x

12000 = 29600*b^7

12000/29600 = b^7

b^7 = 12000/29600

b^7 = 0.405405

b = (0.405405)^(1/7)

b = 0.878991 approximately

------------------------------

We found that

a = 29600b = 0.878991 approximately

So we go from

y = a*b^x

to

y = 29600*0.878991^x

To verify this, plugging x = 0 should lead to y = 29600

Also, plugging in x = 7 should lead to y = 12000 or very close to it.

------------------------------

The last step is to plug in x = 12 to find the car's value in 2012, i.e. x = 12 years after the year 2000.

So,

y = 29600*0.878991^x

y = 29600*0.878991^12

y = 6296.58182216087

y = 6297

The predicted car's value in 2007 is about $6297

what is the density of object X if the mass is 100g with a volume of 6

Answers

Answer:

4.0 g/ml

Step-by-step explanation:

[tex] Volume_X [/tex] = water displaced by X

Water displaced by object X = Final fluid level - Original fluid level

Water displaced by object X = 90 ml - 65 ml = 25 ml

[tex] Volume_{X} = 25 ml [/tex]

Density of rock:

100 grams => 25 ml

x grams => 1 ml

Cross multiply

x*25 = 1*100

25x = 100

25x/25 = 100/25

x = 4

Density of object X = 4 g per 1 ml = 4.0 g/ml

The number of tribbles on the Starship Enterprise are tripling every hour. Initially, five tribbles were brought on board.1A (10 points) Write an equation to model this scenario? Define the variables being used?1C (10 points) How many more tribbles would there be 16 hours later?1B (10 points) At the given rate, how many tribbles will be on the
ship after 8 hours.Show work.

Answers

Using an exponential function, it is found that:

The equation is: [tex]y = 5(3)^x[/tex].After 16 hours, there would be 215,233,605 tribbles.After 8 hours, there would be 32,805 tribbles.

What is an exponential function?

It is modeled by:

[tex]y = ab^x[/tex]

In which:

a is the initial value.b is the rate of change.

In this problem:

The number triples every hour, hence b = 3.Initially, five tribbles were brought on board, hence a = 5.

Thus, the equation is: [tex]y = 5(3)^x[/tex]

16 hours later, the amount is:

[tex]y = 5(3)^{16} = 215233605[/tex]

After 16 hours, there would be 215,233,605 tribbles.

8 hours later, the amount is:

[tex]y = 5(3)^{8} = 32805[/tex]

After 8 hours, there would be 32,805 tribbles.

The sum of two numbers is 100; the first number is 12 less than the second number? What equation best represents the following

Answers

Answer:

Let the first number be f.

Let the second number be s.

f = s-12

f+s = 100

Substitute the f in the first equation for the second equation.

s-12+s = 100

2s-12 =100

2s = 112

s = 56

Therefore f = 56-12 = 44

a. 2125, 1345, 565
b. 2345, 1565, 785
c. 2455, 1675, 895

Answers

Let's start off by defining our first term as u⁰

u⁰ is unknown,u¹=3124,u² is unknown,ect..

Using the recurring formula which states;

u(n+1)=u(n)+d

u¹=u⁰+d

u⁰=u¹-d

u⁰=3125-d

Using the explicit relation, which states;

u(n)=u⁰+nd

u⁵=u⁰+5d

5=3125-d+5d

4d=-3120

d=-780

u²=u¹-780=3125-780=2345

u³=2345-780=1565

u⁴=1565-780=785

You answer is letter C

The arithmetic means of the given sequence is 2455, 1675, 895

let the first term be u(0).

and, first term u(1) = 3124

We can use the recurring formula as:

u(n+1)=u(n)+d

u(1)=u(0)+d

and, u(0)=u(1)-d

and, u(0)=3125-d

Using the explicit relation

u(n)=u(0)+nd

u(5)=u(0)+5d

5=3125-d+5d

4d=-3120

d=-780

and, u(2)=u(1)-780

u(2) = 3125-780

u(2) = 2345

and, u(3)=2345-780

u(3) =1565

and, u(4)=1565-780

u(4) = 785

Answers

Answer:

m∠2 is 55°

Step-by-step explanation:

Let us revise some facts in geometry

In any triangle, the sum of the measures of its angles is 180°If two line intersected at a point, then they formed two pairs of vertically opposite angles, the vertically opposite angles are equal in measures

We will use these facts to solve our question

∵ ∠1 is an angle of a triangle

m∠1 + 40° + 85° = 180° ⇒ 1st fact

→ Add the like terms in the left side

∴ m∠1 + 125° = 180°

→ Subtract 125° from both sides

∴ m∠1 + 125° - 125° = 180° - 125°

m∠1 = 55°

∵ ∠1 and ∠2 formed from the intersecting of two lines

∠1 and ∠2 are vertically opposite angles

m∠1 = m∠2 ⇒ 2nd fact

∵ m∠1 = 55°

m∠2 = 55°

Equations

Pls give an explanation

2x + 12 = 24

I don’t understand it thank you

Answers

Answer:

2x+12=24

first you subtract 12 from both sides

2x+12=24

-12. -12

The 12-12 should cancel itself, the rest of the equation you bring down to get

2x=12 (because 24-12=12)


Now you have 2x=12.
you then divide 2x by both sides.

2x=12

/2x=/2x

The 2x/2x cancels itself out so you then solve for 12/2x.

For this you just divide 12/2 which is 6!

x= 6 is your final answer.
to check this equation you can plug your number back into x to see if it is true! 2(6)+12=24.
6 times 2 is 12 and 12+12 is 24 so your answer (6) is true!
