What could be a reason for isolating a variable in a literal equation

svlad2 [7]

A literal equation is an equation where variables represent known values. Literal equations allow use to represent things like distance, time, interest, and slope as variables in an equation. You isolate one variable because your goal is to solve for just one variable with respect to others.

If the rate of inflation is 2.6% per year, the future price p(t) (in dollars) of a certain item can be modeled by the following

PilotLPTM [1.2K]

Answer:

The current price of the item is $600.

The price of the item 9 years from today will be of $756.

Step-by-step explanation:

Price of the item:

The price of the item, in dollars, after t years, is given by:

$p(t) = 600(1.026)^t$

Current price of the item

This is p(0). So

$p(0) = 600(1.026)^0 = 600$

The current price of the item is $600.

9 years from today.

This is p(9). So

$p(9) = 600(1.026)^9 = 756$

The price of the item 9 years from today will be of $756.

Using a 16-sided number cube, what is the probability that you will roll a multiple of 4 or an odd prime number? The number 1 is

iogann1982 [59]

<h3>Answer: 0.563 (choice C)</h3>

================================================

Explanation:

E = event space

E = set of outcomes we want to happen

E = rolling a multiple of 4 or rolling an odd prime number

E = {4,8,12,16 3,5,7,11,13}

n(E) = number of items in set E

n(E) = 9, (four multiples of 16+five ways to roll odd prime number)

-----

S = sample space

S = set of all possible outcomes (whether we want them to happen or not)

S = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16}

n(S) = number of items in set S

n(S) = 16

-----

P(E) = probability of event space occurring

P(E) = probability of rolling a multiple of 4 or rolling an odd prime number

P(E) = n(E)/n(S)

P(E) = 9/16

P(E) = 0.5625

P(E) = 0.563
