Adrian invested $790 in an account paying an interest rate of 6.9% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $2,550?​

Answers

Answer:17

Step-by-step explanation:

trust me its right, no cap

As per compound interest,  it would take 17 years for the value of the account to reach $2,550

What is the compound interest?

If the invested amount is 'P', the rate of interest is r%, and the time of investment is 'n' years, then the compound interest after mentioned duration is = P[1 -  [tex]e^{rn}[/tex]]

Given, the invested amount (P) = $790.

Rate of interest (r) = 6.9% = 0.069.

Let, the amount is invested for 'n' years.

The value of the amount after 'n' years = $2550.

Now, as per compound interest:

A = P. [tex]e^{rn}[/tex]

⇒ 2550 = 790 [tex]e^{(0.069n)}[/tex]

⇒ [tex]e^{(0.069n)}[/tex] = (2550 ÷ 790)

⇒ [tex]e^{(0.069n)}[/tex] = 3.23

⇒ 0.069n = 1.172

⇒ n = 17

Javier works each weekend at an animal shelter. He earns $8 an hour. He is saving his earnings to go on a ski trip that costs $190.

Becca says that Javier must work at least 6 more hours to have enough money to go on the ski trip. Her work is shown below. Choose True or False about each statement

Becca's solution included all of the hours Javier worked on both weekends. (TRUE OR FALSE?)

Javier worked a total of 23 hours on both weekends. (TRUE OR FALSE?)

Javier earns $198 for 24 hours of work. (TRUE OR FALSE?)

Javier only needs to work one more hour to have enough money for his trip. (TRUE OR FALSE?)

Answers

Answer:

Becca's solution included all of the hours Javier worked on both weekends.

Step-by-step explanation:

Javier needs to work at least 6 more hours. He will earn:

6*8 = $48

He has already got:

$190 - $48 = $142

He worked:

142/8 = 18 hours (rounded)

Total he will have worked:

18 + 6 = 24 hours

Answer choices:

Becca's solution included all of the hours Javier worked on both weekends.

TRUE

Javier worked a total of 23 hours on both weekends.

FALSE. 23*$8 = $184 < $190

Javier earns $198 for 24 hours of work.

FALSE. 24*8 = $192

Javier only needs to work one more hour to have enough money for his trip.

FALSE. Becca says 6 more hours required.

A.y = 2x - 5

B.y = 2x + 5

C.y = 2x - 3

D.y = 2x + 3

Answers

9514 1404 393

Answer:

  C.  y = 2x - 3

Step-by-step explanation:

The y-intercept (b) can be found from ...

  y = mx + b

  y - mx = b . . . . . subtract mx

Here, you are given (x, y) = (-1, -5) and slope m = 2.

  b = -5 -2(-1) = -5+2 = -3

The correct equation is ...

  y = 2x -3 . . . . . matches choice C

_____

On the graph, you can plot point (-1, -5) left of the y-axis 1 unit and down from the x-axis 5 units. The slope of 2 tells you the line will rise 2 units from there to a y-value of -3 when it runs 1 unit to the right to an x-value of 0. That point (0, -3) is the y-intercept, showing you that choice C is correct.

When you add a negative by a negative it equals a negative. Like if you add 1 + 1 it's going to equal 2 which is a positive, not a negative. So the answer is technically 8 + 6 which is 14 and all you have to do is add a negative sign.

What is 4/9 x 5/7 x 1/2

Answers

Answer:

0.16

Step-by-step explanation:

4*5*1=20

9*7*2=126

20/126=10/63

Answer:

10/63

Step-by-step explanation:

First, let's solve 4/9 * 5/7. Multiply the numerator first- 4*5=20. The denominator is 9*7=63. So, this equals 20/63. Now we need to find 20/63 * 1/2. We can cancel out the 2 on the denominator and divide 20 on the numerator by 2. So, you get 10/63 * 1/1, which is 10/63.

The midpoint of \overline{\text{AB}} AB is M(5, 1)M(5,1). If the coordinates of AA are (3, 6)(3,6), what are the coordinates of BB?

Answers

Answer:

(7, -4)

Step-by-step explanation:

The formula for calculating midpoint is expressed as;

M(X, Y) = (x2+x1)/2, (y1+y2)/2

X = x1+x2/2

Y = y1+y2/2

Given

X = 5, Y = 1, x1 = 3, y1 = 6

Get x2

X = x1+x2/2

5 = 3+x2/2

10 = 3+x2

x2 = 10-3

x2 = 7

Get y2;

Y = y1+y2/2

1 = 6+y2/2

2 = 6+y2

y2 = 2-6

y2 = -4

Hence the coordinate of B is at (7, -4)

One political factor that caused World War II was the Treaty of Versailles. The Treaty of Versailles created political tension between countries, as some provisions that were outlined within the treaty were unfair towards some of the parties involved. Take Italy for example; thousands of Italians had died in the war, but Italy was not given the land and reparations they were promised. This led to a rise in nationalism, and more Italians feeling resentment towards the Triple Entente for their abundant debt and little assistance. This is also an economic factor that caused World War II, as the aftermath of World War II left Italy in ruins, both literally and financially, and made it so that they desperately needed hope. This, in turn, led to Benito Mussolini coming into power, boasting promises of a greater Italy in the near future. Similarly, the Treaty of Versailles left Germany in a lot of debt, and many German citizens were suffering. Hitler, a charismatic leader who took advantage of the political and economic turmoil, took over and gave Germany an excuse for their problems: the Jewish population. Another economic factor that caused World War II was the worldwide depression, which put a lot of countries in a very bad position. Also, the rise of fascism and totalitarianism definitely contributed to the way World War II started, as many of the agitators of the war were in the Axis powers, and were under totalitarian dictators.
