Use the given information to determine if the geometric series converges or
lana66690 [7]

Answer:

c) The series diverges. There is no sum.

Step-by-step explanation:

A geometric series is a series of the form:

S = \Sigma_{i=0}^{n} a\cdot r^{i}, \forall i \in \mathbb{N}_{O}

Where:

a - First term of the series, dimensionless.

r - Common ratio, dimensionless.

A geometric series converges only if |r| < 1. As r > 1, the geometric series diverges. Hence, the right answer is C.

alexira [117]

Answer:

A) $8200.

B) 16.4%

Step-by-step explanation:

Here is the complete question: An investment firm invested in two companies last year. They invested $40,000 in company A and made a profit of 15%. They invested $10,000 in company B and made a profit of 22%.

A) What is the investment firms total profit?

B) What is the percent profit of the total investment?

Given: Company A invested $40000 and made profit of 15%

           Company B invested $10000 and made profit of 22%

A) First lets find the profit of company A and B.

Company A= \frac{15}{100} \times \$ 40000= \$ 6000.

∴ Profit of company A is $6000.

Company B= \frac{22}{100} \times \$ 10000= \$ 2200

∴ Profit of company B is $2200.

Total profit= profit of company A+ profit of company B

⇒Total\ profit= \$ 6000+\$ 2200

∴ Total Profit= \$ 8200

Hence, the total profit of investment firm is $8200.

B) Now finding the percentage of total profit made by firm.

Total investment by the firm= \$ 40000+\$ 10000= \$ 50000

∴ Total investment done by the firm is $50000.

Percent of profit= \frac{Total\ profit}{Total\ investment} \times 100

⇒ Percent of profit= \frac{8200}{50000} \times 100

⇒ Percent of profit= \frac{82}{5} = 16.4\%

Hence, 16.4% is the percent profit of the total investment.

Simplify <br><br> (2x^{2} - 5x + 3) - (-x^{2} + 4x - 5)
MrRissso [65]

Answer:

3x^2 - 9x + 8

Step-by-step explanation:

To simplify:

  • Distribute the -1 into the second term.
  • Collect and combine like-terms (terms with the same variables or powers)

The expression can be rewritten has (2x^2 - 5x + 3) -1(-x^2 + 4x - 5)

After distributing the -1, the equation becomes:

  • (2x^2 - 5x + 3) + (x^2 - 4x + 5)

The like-terms are:

  • 2x^2 and x^2
  • -5x and -4x
  • 3 and 5

Combine the like-terms:

  • 2x^2 + x^2 = 3x^2
  • -5x - 4x = -9x
  • 3 + 5 = 8

Substitute the simplified like-terms into the expression, in descending order:

  • 3x^2 - 9x + 8
