An = 4n -13

A1 = 4 (1) - 13

> A1 = -9

A2 = 4(2) - 13

A3 = 4(3) - 13

PLEASE HELP:)<br> Find the value of x. Round your answer to the nearest tenth
vaieri [72.5K]

Answer:

x=42

Step-by-step explanation:

Since we use the sides opposite and adjacent to the given angle, we will use the tangent ratio:

tangentX=\frac{opposite}{adjacent}

Insert the given values:

tanX=\frac{9}{10}

Since we need to find the angle, use the inverse:

x=tan^{-1}(\frac{9}{10})

Insert the equation into a calculator:

x=41.98721249

Round to the nearest tenth:

x=42.0

How can I use context clues and keywords to translate situations into inequalities? Explain with an example of your own.
stiv31 [10]
Consider the following example:

Mira and Lola are looking to hire a hall for their 18th birthday party. They are expecting at least 50 guests and want a hire that will accommodate the party. Write this requirement as an inequality 

Solution: the keyword here is 'at least' because it means that the hall must be able to accommodate a minimum of 50 people. It is a clue that Mira and Lola are expecting more than 50 guests. The inequality symbol for this context is 'more than or equal to' and as inequality, we have x ≥ 50

Are braces are used in interval notation or roster notation?
antoniya [11.8K]

In Mathematics, braces ( {} )are used to symbolize the group of mathematical terms, commonly as the outmost measurement in a difficult expression. Braces are used in roster notation. Wherein within the braces there are a set of elements, which are separated by commas after each element. The set may be a set of whole numbers, or a set of natural numbers, or even a set of integers. While in Interval Notations, brackets and parentheses are used to indicate, whether the endpoints are left out or contained within.
