A person invests 6000 dollars in a bank. The bank pays 6.25% interest compounded monthly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 8800 dollars?
Answer:
6.1
Step-by-step explanation:
A person invests 6000 dollars in a bank. The bank pays 6.25% interest compounded monthly. The person leaves the money in the bank until it reaches 8800 dollars for 6.1 years.
How does compounding work?Suppose that the initial amount of something is P.
Let after one unit of time, it increases by R% (per unit time) and compounds on the resultant total of that quantity, then, after T such units of time, then the quantity would increase to:
[tex]A = P(1 + \dfrac{R}{100})^T[/tex]
A person invests 6000 dollars in a bank. The bank pays 6.25% interest compounded monthly.
Given that :
Principal = 6000
Interest (r) = 6.25% compounded annually
Calculate time, t, if final amount A = 8800
Using the compound interest formula
[tex]A = P(1 + \dfrac{R}{100})^T[/tex]
A = final amount
n = number of times interest is applied per period
[tex]8800 = 6000(1 + {0.0625})^{t}[/tex]
[tex]8800 = 6000(1 + {0.0625})^{t}\\\\\\8800 = 6000({1.0625})^{t}\\\\\\\dfrac{8800} {6000}=({1.0625})^{t}\\\\\\1.46 =({1.0625})^{t}[/tex]
Take the log of both sides
[tex]log 1.46 = t log 1.0675\\\\0.1643 = 0.0263289t\\\\t = 6.1[/tex]

If you could travel to any year in a time machine, what year would you choose and why?
Answer:
If I could travel to any year in a time machine, I would choose a year in future. For example, 3050. Everyone assumes the future according to their own imagination. But nobody knows what it actually looks like. So, if I could time travel, I would travel to a year in future.

If your slope is 1/3 how do you move horizontally?
What is 1/3 as a slope?
The answer is approximately 18.43º. A slope of 1 in 3 means the slope is 1/3. It also means a rise of 1 and a run of 3. On a graph, starting at the origin, go up 1 unit, then from there, go to the right 3 units.

A solid cylinder has a radius of 2 cm and a height of 7 cm. It has a density of 3.1 grams
per cubic em. What is the mass of the cylinder? Use 3.14 for pi and round your answer to the
nearest hundredth
Answer:
Step-by-step explanation:
The first thing you need to do is find the volume.
r = 2cm
h = 7 cm
pi = 3.14
V = pi*r^2 *h
V = 3.14 * 2^2 * 7
V = 3.14 * 4 * 7
V = 87.92 cm^3
Next find the mass using the density formula
Density = mass / volume
Density = 3.1 grams / cm^3
Volume = 87.92 cm^3
3.1 = m / 87.92 Multiply both sides by 87.92
3.1 * 87.92 = m
m = 272.55
Note:
Technically There should be no decimal places. 3.1 is only 2 significant digits. The answer should be 270 grams.

B. $284.20
O $120.00
D. $264.90

Answer:
(0, -2) and (1, 0)
Step-by-step explanation:
y = x² + x - 2 and y = 2x - 2
y = x² + x - 2 ⇔ do not change; y = x² + x - 2
y = 2x - 2 ⇔ multiply by -1 ; -y = - 2x + 2
Now add the two equations:
y = x² + x - 2
(+) -y = - 2x + 2
0 = x² - 2x + x + 0
0 = x² - x
0 = x (x - 1) Factor out x
0 = x; 0 = x - 1 Set each factor = to 0 and solve.
x = 0; x = 1
Substitution the value of x into both equations and solve for y
If x = 0 If x = 1
y = (0)² + 0 - 2 ; y = 2(0) - 2 y = 1² + 1 - 2 ; y = 2(1) -2
y = 0 +0 -2 ; y = 0 - 2 y = 1 + 1 -2 ; y = 2 - 2
y = -2 ; y = -2 y = 0 ; y = 0
Solutions to the question: (0, -2) and (1, 0)
Camden is going to invest $600 and leave it in an account for 12 years. Assuming the
interest is compounded continuously, what interest rate, to the nearest hundredth of
a percent, would be required in order for Camden to end up with $920?
[tex]~~~~~~ \textit{Continuously Compounding Interest Earned Amount} \\\\ A=Pe^{rt}\qquad \begin{cases} A=\textit{accumulated amount}\dotfill & \$920\\ P=\textit{original amount deposited}\dotfill & \$600\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\dotfill &12 \end{cases}[/tex]
[tex]920=600e^{\frac{r}{100}\cdot 12}\implies \cfrac{920}{600}=e^{\frac{3r}{25}}\implies \cfrac{23}{15}=e^{\frac{3r}{25}}\implies \log_e\left( \cfrac{23}{15} \right)=\log_e\left( e^{\frac{3r}{25}} \right) \\\\\\ \ln\left( \cfrac{23}{15} \right)=\cfrac{3r}{25}\implies 25\cdot \ln\left( \cfrac{23}{15} \right)=3r\implies \cfrac{25\cdot \ln\left( \frac{23}{15} \right)}{3}=r \\\\\\ 3.5620\approx r\implies \stackrel{\%}{3.56}\approx r[/tex]
