Consider the system of equations shown below. y = negative 5 x + 1. y = negative 5 x + 10 When graphed, the system consists of t

wo lines that will never meet, no matter how far they are extended. Why are the lines parallel? The linear equations have the same slope and y-intercept. The linear equations have different slopes and y-intercepts. The linear equations have the same slope but different y-intercepts. The linear equations have different slopes but the same y-intercept.\

Which graph represents the function f(x)=4*3^x (f times x equals 4 times three to the power of x)
pychu [463]

Answer:

The answer to your question is the first graph in the second line.

Step-by-step explanation:

First graph in the first line: it shows a positive graph that intercepts the y-axis in 5, then this graph is not the correct answer.

Second graph in the first line: it shows a negative graph, this option is incorrect, we look for a positive graph.

First graph in the second line: is correct because is a positive graph and intercpts the y-axis in 4.

Second graph in the second line: is incorrect although it is a positive graph, it intercepts the y-axis in 3.

The Students' Conjectures Emily and Zach have two different polynomials to multiply: Polynomial product A: (4x2 – 4x)(x2 – 4) Po
noname [10]

Complete Question:

Emily and Zach have two different polynomials to multiply: Polynomial product A: (4x2 – 4x)(x2 – 4) Polynomial product B: (x2 + x – 2)(4x2 – 8x) They are trying to determine if the products of the two polynomials are the same. But they disagree about how to solve this problem.

Answer:

A = B

Step-by-step explanation:

<em>See comment for complete question</em>

Given

A: (4x^2 - 4x)(x^2 - 4)

B: (x^2 + x - 2)(4x^2 - 8x)

Required

Determine how they can show if the products are the same or not

To do this, we simply factorize each polynomial

For, Polynomial A: We have:

A: (4x^2 - 4x)(x^2 - 4)

Factor out 4x

A: 4x(x - 1)(x^2 - 4)

Apply difference of two squares on x^2 - 4

A: 4x(x - 1)(x - 2)(x+2)

For, Polynomial B: We have:

B: (x^2 + x - 2)(4x^2 - 8x)

Expand x^2 + x - 2

B:(x^2 + 2x - x - 2)(4x^2- 8x)

Factorize:

B:(x(x + 2) -1(x + 2))(4x^2- 8x)

Factor out x + 2

B:(x -1) (x + 2)(4x^2- 8x)

Factor out 4x

B:(x -1) (x + 2)4x(x- 2)

Rearrange

B: 4x(x - 1)(x - 2)(x+2)

The simplified expressions are:

A: 4x(x - 1)(x - 2)(x+2) and  

B: 4x(x - 1)(x - 2)(x+2)

Hence, both polynomials are equal

A = B

Find the margin of error for the given values of c, o, and n.
Alika [10]

Using the z-distribution, it is found that the margin of error is of 0.059.

We are given the standard deviation for the population, hence the <em>z-distribution</em> is used.

<h3>What is the margin of error for a z-confidence interval?</h3>

It is given by:

M = z\frac{\sigma}{\sqrt{n}}

In which:

  • z is the critical value.
  • \sigma is the population standard deviation.
  • n is the sample size.

In this problem, the parameters are:

  • \sigma = 0.25, n = 49.
  • Confidence level of 0.90, hence, using a z-distribution calculator, the critical value is z = 1.645.

Then:

M = z\frac{\sigma}{\sqrt{n}}

M = 1.645\frac{0.25}{\sqrt{49}}

M = 0.059

The margin of error is of 0.059.
