♦Rachel, a 45-year-old female, bought a $120,000, a 20-year life insurance policy through her employer. Rachel is paid biweekly. How much is deducted from each of her paychecks for life insurance? Use the Table.
♦Dawson, a 42-year-old male, bought a $180,000, 20-year life insurance policy. What is Dawson's annual premium? Use the table.
Dawson is 42, with a 20 year premium coverage, which will amount to $13.68 per $1000. Multiply $13.68 with 180 (because there are 180 $10,000)
13.68 x 180 = $2462.40
annual premium = $2462.40

How much water can be held by a cylindrical tank with a radius of 12 feet and a height of 30 feet?
Jerry goes to the bank and borrows $9,000 for farm equipment. The simple yearly interest is 9.5% and he pays off the loan over a period of 2 years with 24 equal monthly payments. What’s Jerry’s monthly payment
Jerry's monthly payment can be calculated using the formula for the monthly payment on a loan. Plugging in the given values will give the exact monthly payment amount.
Explanation:To calculate Jerry's monthly payment, we can use the formula for the monthly payment on a loan:
Monthly Payment = P × r × (1 + r)^(n) / ((1 + r)^(n) - 1)
Where:
P is the principal amount borrowed, which is $9,000r is the monthly interest rate, which is calculated by dividing the annual interest rate by 12 and converting it to a decimal. In this case, it would be 9.5% / 12 = 0.0079 (rounded to four decimal places)n is the total number of payments, which is 2 years × 12 months = 24 monthsPlugging in the values:
Monthly Payment = $9,000 × 0.0079 × (1 + 0.0079)^(24) / ((1 + 0.0079)^(24) - 1)
Simplifying this equation will give us the monthly payment amount.

The sum of the first 30 terms of the sequence an=6n+5 is
Answer:
[tex]S_{30}=2940[/tex].
Step-by-step explanation:
Given : [tex]a_{n} =6n+5[/tex].
To find : The sum of the first 30 terms .
Solution: We have given [tex]a_{n} =6n+5[/tex].
For n = 1
[tex]a_{1} =6(1)+5[/tex].
[tex]a_{1} =6+5[/tex].
[tex]a_{1} =11[/tex].
For n =2
[tex]a_{2} =6(2)+5[/tex].
[tex]a_{2} =17[/tex].
Common difference = 17 - 11 = 6.
Sum of nth term : [tex]S_{n} =\frac{n}{2}[2a+(n-1)d][/tex].
d = common difference = 6.
For n = 30 .
[tex]S_{30} =\frac{30}{2}[2(11+(30-1)6][/tex].
[tex]S_{30} =15[22+29 *6][/tex].
[tex]S_{30} =15[22+29 *6][/tex].
[tex]S_{30} =15[22+174][/tex].
[tex]S_{30} =15[196][/tex].
[tex]S_{30}=2940[/tex].
Therefore, [tex]S_{30}=2940[/tex].

There are 20,000 owls in the wild. Every year the population decreases by 8%. How many owls will there be after 8 years?
After 8 years, there will be approximately 10,260 owls remaining in the wild. This calculation is based on an initial population of 20,000 owls decreasing by 8% annually, yielding a final population using the formula for exponential decay.
To find out how many owls will remain after 8 years, we can use the formula for exponential decay:
[tex]\[ \text{Final population} = \text{Initial population} \times (1 - \text{Rate of decrease})^{\text{Number of years}} \][/tex]
Given:
Initial population (P) = 20,000 owls
Rate of decrease (r) = 8% = 0.08
Number of years (t) = 8
Plugging in the values:
[tex]\[ \text{Final population} = 20,000 \times (1 - 0.08)^8 \][/tex]
[tex]\[ \text{Final population} = 20,000 \times (0.92)^8 \][/tex]
[tex]\[ \text{Final population} \approx 20,000 \times 0.513 \][/tex]
[tex]\[ \text{Final population} \approx 10,260 \][/tex]
So, after 8 years, there will be approximately 10,260 owls remaining in the wild.

The base of a parallelogram is 24 inches longer than three times the height. The area of the parallelogram is 384 square inches. What is the height?
The height is x = ________ inches.
To find the height of the parallelogram, set up the equation (3x + 24) x = 384 using the formula for the area of a parallelogram. Solve the resulting quadratic equation to find that x, representing the height, is 8 inche
The student is trying to find the height of a parallelogram when the base is 24 inches longer than three times the height and the area is 384 square inches. Let the height of the parallelogram be represented by x inches. According to the problem, the base (b) is 3x + 24 inches. Using the formula Base x Height = Area of parallelogram, we can set up the equation:
(3x + 24) x= 384
Now solve for x using the distributive property:
3x^2 + 24x = 384
Next, set the equation to zero:
3x^2 + 24x - 384 = 0
Divide the entire equation by 3 to simplify:
x^2 + 8x - 128 = 0
Factor the quadratic equation:
(x + 16)(x - 8) = 0
Set each factor equal to zero:
x + 16 = 0 or x - 8 = 0
Since the height cannot be negative, x = 8 is the solution. Therefore, the height of the parallelogram is 8 inches.

The solution set for 7q2 − 28 = 0 is { }. (Separate the solutions with a comma) NextReset
Answer:
{ 2,-2}
Step-by-step explanation:
In order to solve this set we just have to first clear the "q":
[tex]7q^{2} -28=0\\7q^{2} -28+28=+28\\7q^{2} =28\\\frac{7q^{2}}{7} =\frac{28}{7} \\q^{2}=4\\\sqrt{q^{2}} =\sqrt{4} \\q= 2, -2[/tex]
So as we know the solution for a square root is always a negative and positive number, so the solutions ser for 7q2-28=0 is 2 and -2
Which ordered pair will be the solution for the function y = 12 - x?
(7, 4)
(6, 6)
(4, 9)
(2, 14)
The solution to the function y = 12 - x is the ordered pair (6, 6) because when we substitute x = 6 into the function, the result, y, is also 6, which matches the given y-value in the pair.
Explanation:To find the ordered pair that is a solution for the function y = 12 - x, we need to substitute the x-values of each given ordered pair into the equation and see which one gives a resulting y-value that matches the one in the pair.
(7, 4): y = 12 - 7 = 5 – This does not match the y-value of 4.(6, 6): y = 12 - 6 = 6 – This is correct, as it matches the y-value of 6.(4, 9): y = 12 - 4 = 8 – This does not match the y-value of 9.(2, 14): y = 12 - 2 = 10 – This does not match the y-value of 14.Therefore, the solution to the function is the ordered pair (6, 6).

How many real number solutions exist for 2x2 + 8x + 8 = 0?
Final answer:
There are no real number solutions for the given equation.
Explanation:
The given equation is 2x² + 8x + 8 = 0. To find the number of real number solutions for this equation, we can use the discriminant of the quadratic equation. The discriminant is given by the formula D = b² - 4ac, where a, b, and c are the coefficients of the quadratic equation.
In this case, a = 2, b = 8, and c = 8. Substituting these values into the formula, we get D = 8² - 4(2)(8) = 16 - 64 = -48.
Since the discriminant is negative (-48), there are no real number solutions for the equation. Therefore, the answer is 0.
