Payout Annuities:
1. You want to be able to withdraw $30,000 from your account each year for 15 years after you retire.
You expect to retire in 30 years.
If your account earns 5% interest, how much will you need to deposit each year until retirement to achieve your retirement goals?
To achieve your retirement goals of withdrawing $30,000 per year for 15 years, you will need to deposit approximately $121,200 each year until retirement.
Explanation:To determine how much you need to deposit each year until retirement, you can use the formula for the present value of an annuity. The formula is:
PV = PMT x ((1 - (1 + r)^-n) / r)
Where:
In this case, the annuity payment amount is $30,000, the interest rate is 5%, and the number of periods is 15 years. Plugging these values into the formula:
PV = $30,000 x ((1 - (1 + 0.05)^-15) / 0.05)
Simplifying the equation:
PV = $30,000 x ((1 - 1.798) / 0.05)
PV = $30,000 x (0.202 / 0.05)
PV = $30,000 x 4.04
PV = $121,200
Therefore, you will need to deposit approximately $121,200 each year until retirement to achieve your retirement goals.

What does −2/3(12c−9)+14c simplify to?
Answer:
The simplified form of the provided expression is [tex]6c+6[/tex] or [tex]6(c+1)[/tex]
Step-by-step explanation:
Consider the provided expression.
[tex]\frac{-2}{3}(12c-9)+14c[/tex]
Use the distributive property:
[tex]a(b+c)=ab+ac[/tex]
By using the above property we can simplify it as shown:
[tex]\frac{-2}{3}\times 12c-\frac{-2}{3}\times 9+14c[/tex]
[tex]-2\times 4c+2\times 3+14c[/tex]
[tex]-8c+6+14c[/tex]
Add or subtract the like terms.
[tex]6c+6[/tex] or [tex]6(c+1)[/tex]
Thus, the simplified form of the provided expression is [tex]6c+6[/tex] or [tex]6(c+1)[/tex]
The simplest form of expression by applying distributive property would be, 6 (c + 1)
Given that,
The expression is,
[tex]\dfrac{- 2}{3} (12c - 9) + 14c[/tex]
Now, used the concept of distributive property to simplify the expression,
[tex]\dfrac{- 2}{3} (12c - 9) + 14c[/tex]
Apply distributive property,
[tex][\dfrac{- 2}{3} \times 12c - (\dfrac{- 2}{3} )\times 9] + 14c[/tex]
[tex][- 2 \times 4c + 2 \times 3] + 14c[/tex]
[tex][- 8c + 6] + 14c[/tex]
Combine like terms,
[tex]- 8c + 14c + 6[/tex]
[tex]6c + 6[/tex]
Take 6 as a common term,
[tex]6 (c + 1)[/tex]
So, the solution of expression 6 (c + 1).

We have a polynomial:
f(x) = x⁵ − 8x⁴ + 21x³ − 12x² − 22x + 20
The three roots of this polynomial function are −1, 1, and 3 + i.
We can write the function in a factored form:
f(x) = (x - 1)(x⁴ - 7x³ + 14x² +2x - 20)
Again factoring the above polynomial:
f(x) = (x - 1)(x + 1)(x - 2)(x² -6x + 10)
The roots of the polynomial are
x - 1 = 0
x = 1
x + 1 = 0
x = -1
x - 2 = 0
x = 2
x² - 6x + 10 = 0
The above quadratic equation has two complex roots.
x = 3 + i
x = 3 - i
Thus, the f(x) has three real roots and two imaginary roots option (D) is correct.

Is m=0.75d-2 proportional?
Answer:
No, the equation m=0.75d-2 does not represent proportional relationship.
Step-by-step explanation:
The given equation is
[tex]m=0.75d-2[/tex]
We need to check whether the given equation represents proportional relationship or not.
If variable y is proportional to variable x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is the constant of proportionality.
At x=0 the value of y is 0. It means, if a linear equation represents proportional relationship then it must be passes though the origin.
Substitute d=0 in the given equation.
[tex]m=0.75(0)-2[/tex]
[tex]m=-2[/tex]
The line passes through the point (0,-2).
Since the line does not pass through the origin, therefore it does not represent proportional relationship.

For integer values of a and b, b^a = 8. The ratio of a to b is equivalent to the ratio of c to d, where c and d are integers. What is the value of c when d = 10?
To find the value of c when d = 10, we first need to determine the values of a and b. Given that b^a = 8, we know that 8 is the result of raising b to the power of a.
Since the question states that a and b are integers, there are a limited number of possibilities to consider. Let's examine the possible combinations of a and b that satisfy this equation: [tex]1^3 = 1 2^3 = 8 3^2 = 9[/tex](which is not 8) [tex]4^2 = 16[/tex] (which is not 8) [tex]5^1 = 5 6^1 = 6 7^1 = 7 8^1 = 8[/tex]From these calculations, we find that the only combination that satisfies the equation is a = 3 and b = 2. Now, let's consider the ratio of a to b and the ratio of c to d.
The ratio of a to b is a/b = 3/2. The question states that the ratio of a to b is equivalent to the ratio of c to d, which means: a/b = c/d Given that d = 10, we can substitute the value into the equation: [tex]3/2 = c/10[/tex] Next, we can cross-multiply to solve for c: [tex]3 * 10 = 2 * c 30 = 2[/tex] c Dividing both sides by 2, we get: c = 15 Therefore, when d = 10, the value of c is 15. In conclusion, when d = 10, the value of c is 15 based on the given equation and calculations.
