What is the sum of the first 10 terms of the geometric series 2 + 6 + 18 + 54 + 162 + ...?

Answers

2 + 6 + 18 + 54 + ...

 This is a geometric sum and there is a way to find the sum of however many terms as you would like.

 The initial term is S1 = 2, the ratio of successive terms is r = 3.

 The sum for a geometric sequence of the first n terms is given by

 Sn = S1(1 - rn)/(1 - r)

Apply this formula for n = 10.

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the discriminant of the function be represented as D

Now , the value of D is

D = ( b² - 4ac )

And , when ( b² - 4ac ) is positive, we get two real solutions

When a quadratic function contacts the x-axis on two different occasions, the function should be positive in this case. When the quadratic function intersects the x-axis precisely on one occasion, the function should be equal to zero.

When the x-axis shouldn't cross the function graph, the function should be smaller than zero.

Hence , the discriminant of the function is positive

Step-by-step explanation:

#12

The square root of a number is a whole number between 50 and 100.

Let the number be n, given:

50 < √n < 100

Square both sides:

50² < n < 100²2500 < n < 10000

The number is a perfect square between 2500 and 10000.

Let the number is n:

√n > n

Square both sides:

n > n²n² - n < 0n(n - 1) < 0

Solution is:

0 < n < 1

Remember that 20% is your part (coinsurance) so the insurer’s percent is 80% for the first formula. Show how you are getting the answer.

Answers

The insurer's part of the medical bill is 80 percent of the medical bill after deductible

The insurer would cover 80 percent of the insured's claims on the medical bill based on coinsurance agreement. However, the insured would have to pay deductible prior to coinsurance(80,20 share of bill)

Example: if insured's annual deductible is $2000 and coinsurance is 80:20, a medical bill of $10000, assuming the insured has not paid any deductibles, would amount to 80% of $8000(after subtracting deductibles) for the insurer"s cover and the rest for the insured.

Insurance deductibles are paid before your health plan covers its part of the medical bill, usually 80 percent.

Depending on your agreement with the insurer there could also be a copay on the insurance policy.

Answers

y = -1/2x - 10

ex : -10 is x, -5 is y, -1/2 is slope

y = mx + b, m is slope, solving for b (y-intercept)

-5 = -1/2(-10)+b
-5 = 5 + b

try to get b by itself, so minus the positive 5

-5-5 = b, so -10 = b

which leads to y = -1/2x - 10

What annual rate of interest compounded annually is required to double an investment in 6 years?

Answers

Answer:

Approximately 12.25%

Step-by-step explanation:

The compound interest formula is:

Final balance = Principal * (1 + interest rate/number of times interest compounded per year)^(number of times interest compounded per year * years elapsed)

If we want our final balance to be twice our principal, our formula looks like:

[tex]2P = P * (1 + \frac{r}{1})^{1*6}[/tex]

We can divide our principal from both sides to get the following equation:

[tex]2 = (1 + \frac{r}{1})^{6}[/tex]

Since anything divided by 1 is itself, we can simplify a little further to:

[tex]2 = (1 + r)^{6}[/tex]

Now, we need to solve for r.  We can start by taking the sixth root of both sides.

[tex]\sqrt[6]{2} = 1 + r[/tex]

Then subtract 1 from both sides:

[tex]\sqrt[6]{2} -1 = r[/tex]

Finally, we can use a calculator to get a decimal approximation:
