You are considering different investment strategies to save for your retirement.
Option 1: You invest $50/ month at a rate of 3.5% APR compounded monthly for 35 years.
Option 2: You invest $150/ quarter at a rate of 4.15% APR compounded monthly for 35 years.
Option 3: You invest $4,000 at a rate of 5.5% APR compounded monthly for 35 years.
Complete the table below and answer the questions below it.
You may use this calculator http://www.mycalculators.com/ca/savecalcm.html to help you.
(Hint: The “Present Value” for options 1 and 2 is 0 while for option 3 it is $4,000.00. Also, the
top radio button in the Contributions box should be selected so that contributions are made at the beginning of the period.)

Table:
Option # | Contributions | Final Balance | Total Interest Earned
1
2
3

1) How did you calculate the contribution for each option? In which option would you
contribute the least?

2) Which option yielded the highest amount at the end of the 35 years and what was the basis of the plan?

3) What is the difference in the principal invested for the highest and lowest final
balances? What is the difference in the interest earned?

4) What plan would you recommend for the largest return on investment? (This means
the most interest for the least amount invested)

5) How does the differing interest rates in each option play into your recommendation?

I would appreciate full feedback! Thank you :)

Answers

Return on investment increases as the interest rate applied, the duration of investment, and the principal invested increases.

The responses are as follows;

1) Total contribution = Single contribution Value × Number of contributions2) Option 23) $-4,0004) Option 35) The higher interest rate increases the return on investment

Reasons:

Option 1: Investment

The present value = 0

The contributions made = $50 monthly

APR of investment = 3.5%

Number of years of investment = 35 years

The contribution = $50 × 12 × 35 = $21,000

Future value (final balance) = $41,230.22

Interest Earned = $41,230.22 - $21,000 = $20,230.22

Option 2: Investment

The present value = 0

The contributions made = $150 per quarter

APR on investment = 4.15%

Number of years of investment = 35 years

The contribution = $150 × 4 × 35 = $21,000

Future value = $47,503.88

Interest Earned = $47,503.88 - $21,100

Option 3: Investment

Present value = $4,000

APR on investment = 5.5%

Number of years of investment = 35 years

The contribution = $4,000

Future value = $27,300.26

Interest Earned = $27,300.26 - $4,000 = $23,300.26

[tex]\begin{array}{|c|c|c|c|}Option \ number&Contributions&Total \ Interest \ Earned&Final \ Balance\\1&\$50&\$20,230.22&\$41,230.22\\2&\$150&\$26,403.88&\$47,503.88\\3& \$4,000 &\$23,300.26 &\$27,300.26 \end{array}\right][/tex]

1) The total contribution is given by the product of the monthly contribution and the number of timer units.

2) The option that yielded the highest amount at the end of 35 years is the option 2.

The basis of the plan is quarterly investment of $150 and an annual interest rate of 4.15% compounded monthly.

3) The principal with the highest final balance is the principal for Option 2. which is 0

The principal that has the lowest final balance is the principal for option 3 which is $4,000

The difference in the principal for the highest and lowest final balances is  

$0 - $4,000  = $-4,000

4) The plan recommended for the largest return on investment is option 2, in which the amount invested increased by more than 600%

5) The higher the interest rate, the higher the return on the amount invested.

The population of a hornet nest experienced growth at a 20% monthly rate, compounded
continuously. At the end of a 5 month period, the population reached a size of 815
hornets.
Assuming that every month has 30 days, how many hornets were in the nest at the
beginning of the 5 months according to the exponential growth function? Round your
answer to the nearest whole number, and do not include units.

Answers

Using an exponential function, it is found that at the beginning, there were 328 hornets.

An increasing exponential function has the following format:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

A(0) is the initial value.r is the growth rate, as a decimal.

In this problem, there is a growth of 20%, hence [tex]r = 0.2[/tex].

After 5 months, the size is of 815, hence, when [tex]t = 5, A(t) = 815[/tex], and this is used to find A(0).

[tex]A(t) = A(0)(1 + r)^t[/tex]

[tex]815 = A(0)(1 + 0.2)^5[/tex]

[tex]A(0) = \frac{815}{(1.2)^5}[/tex]

[tex]A(0) = 328[/tex]

At the beginning, there were 328 hornets.

[tex]f(x) = -6x^2 + 7x + 4[/tex]

Step-by-step explanation:

For x = 1

[tex]a(1)^2 + b(1) + c = 5 \Rightarrow a + b + c = 5[/tex] (1)

For x = -3,

[tex]a(-3)^2 + b(-3) + c = -71[/tex]

[tex]\Rightarrow 9a - 3b + c = -71[/tex] (2)

For x = 3,

[tex]a(3)^2 + b(3) + c = -29[/tex]

[tex]\Rightarrow 9a + 3b + c = -29[/tex] (3)

Let's add Eqn(2) and Eqn(3) together to eliminate b:

[tex]\Rightarrow 18a + 2c = -100[/tex] (4)

Next, multiply Eqn(1) by 3 and then add to Eqn(2) to get

[tex]\Rightarrow 12a + 4c = -56[/tex] (5)

Then we want to eliminate c by multiplying Eqn(4) by -2 and then adding to Eqn(5) and we will get

[tex]-24a = 144 \Rightarrow a = -6[/tex]

Now that we have the value for a, we can use either Eqn(4) or Eqn(5) to solve for c and we will get

[tex]12(-6) + 4c = -56 \Rightarrow c = 4[/tex]

Using the values of a and c on Eqn(1), we find that [tex]b = 7[/tex] so therefore, our function f(x) has a form

Up arrow, right arrow, down arrow, left arrow, up arrow, right arrow, down arrow, left arrow. What's the conjecture

Answers

Answer:

The correct option is;

If one reflects a figure across the y-axis, the points of the image can be found using the pattern (x, y) Right-arrow (x, -y).

If one reflects a figure across the y-axis, the points of the image can be found using the pattern (x, y) Right-Arrow (-x, y).

Taking the result from the first reflection (x, -y) and applying the second mapping rule will result in (-x, -y), not (y, x), which reflection across the line y = x should give

Step-by-step explanation:

We have that for reflection across the x-axis, (x, y) → (x, -y)

For reflection across the y-axis, (x, y) → (-x, y)

Therefore, given that the pre-image before the reflection across the y-axis is (x, -y), we have;

For reflection across the y-axis, (x, -y) → (-x, -y)

For reflection across the line, y = x, gives (x, y) → (y, x) which is not the same as (-x, -y)

Aaron creates a stacked cake comprised of three cylindrical sections as pictured below, and plans to cover the top of each section with a different color icing. Each lower section is a total of two inches wider than the section above it. If the yellow top of the upper section has an area of 12.56 square inches, what is the approximate area of the green visible portion of the bottom section which he will need to cover with icing?

Answers

Answer:

Step-by-step explanation:

A = πR²

top layer has a radius of

R = √(12.56/π) = 2 inches

The middle layer has a radius of 3 inches and an area of

A₂ = π3² = 9π in²

The bottom layer has a radius of 4 inches and an area of

A₃ = π4² = 16π in²

so the visible area on the bottom layer has an area of

16π - 9π = 7π in² or about 22 in²

Answers

9514 1404 393

Answer:

120 mL of 25% solution60 mL of 10% solution

Step-by-step explanation:

Let q represent the quantity of 25% solution in the mix. Then 180-q is the quantity of 10% solution. The quantity of acid in the mix is ...

  0.10(180 -q) +0.25(q) = 0.20(180)

  18 +0.15q = 36 . . . . simplify

  0.15q = 18 . . . . . . . . subtract 18

  q = 18/0.15 = 120 . . . . divide by the coefficient of q

  180-q = 60

The scientist should mix 120 mL of 25% solution with 60 mL of 10% solution.

What is the slope-intercept form of an equation of a line that passes through the point (0,-1) and is perpendicular to 5x-y=3?

Answers

Answer:

y = -1/5x - 1

Step-by-step explanation:

Perpendicular lines slopes are negative reciprocals of each other.

Write the given equation in the slope-intercept form: y = mx + b

5x - y = 3

-y = -5x + 3

y = 5x - 3       multiply by -1

The slope of the given line is 5 ( the coefficient of the x-term).

The slope of the new equation will -1/5 (this is the negative reciprocal of 5).

Next find "b"  using y = mx + b, the new slope -1/5 and the point (0, -1)

y = mx + b

-1 = -1/5(0) + b

-1 = 0 + b

-1 = b  

Now write the equation y = -1/5x - 1
