I need to write a letter to my principal why you cant bring valuable items like cell phones

EastWind [94]

Our experience with students bringing cell phones and entertainment systems to school has been that too often they go missing (lost or stolen) either in school or on the bus. This creates many issues regarding questioning students and investigating incidents. We feel it is the safest policy for students not to have them in school. As our sites are small, everyone has the ability to make and receive calls to their parents in an emergency. We also feel it can lead to miscommunication if students are being communicated to directly and administration or staff is not also informed.

This should be good

Donald Duck's car gets 30 miles per gallon. How many miles can he drive on 9.2 gallons of gas? At $ 2.19 a gallon, how much woul

Vinil7 [7]

Answer:

276 miles, $ 20.148

Step-by-step explanation:

Given:

Donald Duck's car travels in 1 gallon gas = 30 miles

Cost of 1 gallon = $ 2.19

Question asked:

Distance travel in 9.2 gallons = ?

Cost of 9.2 gallons of gas = ?

Solution:

By applying unitary method:

His car travels in 1 gallon = 30 miles

His car will travel in 9.2 gallons = $9.2\times30$

= 276 miles

Cost of 1 gallon = $ 2.19

Cost of 9.2 gallons = $9.2\times2.19$

= $ 20.148

By using algebra properties and trigonometric formulas we find that the trigonometric expression $\frac{1}{1 - \sin x} - \frac{1}{1 + \sin x}$ is equivalent to the trigonometric expression $\frac{2\cdot \tan x}{\cos x}$ .

<h3>How to prove a trigonometric equivalence by algebraic and trigonometric procedures</h3>

In this question we have trigonometric expression whose equivalence to another expression has to be proved by using algebra properties and trigonometric formulas, including the fundamental trigonometric formula, that is, cos² x + sin² x = 1. Now we present in detail all steps to prove the equivalence:

$\frac{1}{1 - \sin x} - \frac{1}{1 + \sin x}$ Given.

$\frac{1 + \sin x - 1 + \sin x}{1 - \sin^{2}x}$ Subtraction between fractions with different denominator / (- 1) · a = - a.

$\frac{2\cdot \sin x}{\cos^{2}x}$ Definitions of addition and subtraction / Fundamental trigonometric formula (cos² x + sin² x = 1)

$\frac{2\cdot \tan x}{\cos x}$ Definition of tangent / Result

By using algebra properties and trigonometric formulas we conclude that the trigonometric expression $\frac{1}{1 - \sin x} - \frac{1}{1 + \sin x}$ is equal to the trigonometric expression $\frac{2\cdot \tan x}{\cos x}$ . Hence, the former expression is equivalent to the latter one.
