Using a minimum of two sentences, describe how to write the function, fx) = (x + 2)^2-3, in standard form

Answer:

The standard form of given function is x² + 4 x + 1

Step-by-step explanation:

Given function as :

f(x) = (x + 2)² - 3

The given algebraic expression as a function of x

The standard form of any equation is written as

ax² + bx + c = 0

where a , b , c are the constant term and x is the variable

Or, f(x) = (x² + 4 x + 4) - 3

or, f(x) = x² + 4 x + 1

Hence The standard form of given function is x² + 4 x + 1 Answer

The lifetime of a lightbulb in a certain application is normally distributed with mean μ = 1500 hours and standard deviation σ = 200 hours. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. What is the probability that a lightbulb will last more than 1800 hours?

Answer:

0.000647588

Step-by-step explanation:

The normal probability function formula is:

To find the probability that a lightbulb will last more than 1800 hours, we can plug in x = 1800, μ = 1500, and σ = 200

So the probability that a lightbulb will last more than 1800 hours is 0.000647588

Roger is sixteen years old and eats granola bars. He attends P.R. Walker High School. In this example, is the independent variable.

The example in that question, the age of Roger is the independent variable. This means that the variable left is granola bars. This make it the dependent variable since it depends on the age of Roger.

The age does not depend on the amount of granola bars eaten by Roger but the amount of granola bars may depend with age of Roger.

The age does not depend on the amount of granola bars eaten by Roger but the amount of granola bars may depend with age of Roger.

How does 4/15=14/n? What does n equal?

4/15 = 14/n

4 * n = 14 * 15
