Choose the correct graph that illustrates the equation by clicking on the image{(x, y): -1 ≤ x ≤ 3
ololo11 [35]

See attachment for the graph of the inequality -1 ≤ x ≤ 3

<h3>What is a linear inequality?</h3>

A linear inequality is an inequality that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

<h3>How to determine the correct graph?</h3>

In this question, the expression of the inequality is given as:

-1 ≤ x ≤ 3

The above means that the set of values of x is between -1 and 3 (-1 and 3 are inclusive of the values of x)

So, the possible values of x are -1, 0, 1, 2 and 3

When the graph of the inequality is plotted, the graph would have the following properties:

  • x values = -1, 0, 1, 2 and 3
  • Double closed circles or thick lines

Next, we plot the graph of the inequality -1 ≤ x ≤ 3

See attachment for the graph of the inequality -1 ≤ x ≤ 3

The base of a cylindrical candle has an area of
Fudgin [204]

The volume of the cylindrical candle that has a base area of 12.56 inches is 12.56h inches³.

<h3>Volume of of cylinder</h3>

volume of a cylinder = πr²h

where

  • r = radius
  • h = height

Therefore,

volume of a cylinder = πr²h

Area of the base = πr²

Therefore,

Area of the base = 12.56 inches²

volume of the cylindrical candle = 12.56h inches³

The sum of the first 3 terms of a geometric series is 171 and the common ratio is 2/3
Nimfa-mama [501]
<h3>Answer:  81</h3>

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

Work Shown:

a = first term

a*(2/3) = (2/3)a= second term

(2/3)a*(2/3) = (4/9)a = third term

note how I multiplied each previous term by the common ratio (2/3) to get the next term

Add up the three terms

a + (2/3)a + (4/9)a = (9/9)a + (6/9)a + (4/9)a = (19/9)a

Set this equal to 171, which is what we want the first three terms to sum to, then solve for 'a'

(19/9)a = 171

a = (9/19)*171

a = 81 is the first term

------------------------------------

Checking the answer:

a = 81 = first term

(2/3)*a = (2/3)*81 = 54 = second term

(4/9)*a = (4/9)*81 = 36 = third term

adding up the three terms gets us

81+54+36 = 171

so we have confirmed the answer
