Is the answer option c?
Masja [62]

Answer:

Discrete

Step-by-step explanation:

A set can simply be defined as a list of values. There are many different types of sets, some are intervals, others are enumerated numbers. Often, a set composed of values that are listed is referred to as a discrete set. Discrete sets can be a list of information, or "isolated points". Knowing this information, the most logical answer to fill in the blank is "discrete".

"If a set is made up of isolated points and can be written as a list, it is called a <u>discrete</u> set."

How long will it take $5,000 to double in an account that pays 1.6% simple interest?
forsale [732]

Answer:

43.667 years

Step-by-step explanation:

Simple Interest Rate Formula: A = P(1 + r)ⁿ

Step 1: Define variables

A = 10,000

P = 5,000

r = 0.016

n = unknown

Step 2: Substitute variables

10,000 = 5,000(1 + 0.016)ⁿ

Step 3: Solve for <em>n</em> time

2 = (1.016)ⁿ

\log_{1.016}2

43.667 years

Which of the numbers below correctly describes 4.7 h?
Vera_Pavlovna [14]

Answer: a. 4,700 mh

Step-by-step explanation:

Assuming:

1 mh = 10^{-3} h

1 kh = 10^{3} h

1 ph = 10^{-12} h

The only option that is correct is a. 4,700 mh, let's prove it with the following conversion:

4.7 h \frac{1 mh}{10^{-3} h} = 4,700 mh

Lynna [10]

9514 1404 393

Answer:

 $27,026.90

Step-by-step explanation:

The future value formula can be solved to find the present value required.

  FV = P(1 +r)^t . . . future value of P compounded at annual rate r for t years

  $100,000 = P(1 +0.08)^17

  P = $100,000/3.70002 . . . . divide by the coefficient of P

  P = $27,026.90

You would need to deposit #27,026.90 now to reach this goal.
