You are choosing a new cell phone. The screen on your current phone is 10.8 cm high and 6.1 cm wide. The screen on the new phone
Leto [7]

Answer:

19.68 cm^2

Step-by-step explanation:

<em>Area of Current Phone </em>

First, find the area of the current phone. We can assume the screen is rectangular. The area of a rectangle can be found using:

a=l*w

We know the length is 10.8, and the width is 6.1, so we can substitute them in

a=10.8*6.1

a=65.88

Current Phone: 65.88 cm^2

<em>Area of New Phone </em>

Find the area of the new phone.

a=l*w

We know the length is 12.4, and the width is 6.9, so we can substitute them in

a=12.4*6.9

a=85.56

New Phone: 85.56 cm^2

<em>Difference </em>

We want to find how much larger the new phone screen is. To do this, find the difference between the new phone area, and the current phone area.

new phone - current phone

85.56-65.88

19.68

<em><u>The new phone screen is 19.68 cm^2 larger than the current phone screen</u></em>

5) Establish the indentity (cot + tan ) sin = sec . Show each step to justify your conclusion.
katen-ka-za [31]

Answer:

Step-by-step explanation:

Identities : -

cot = cos / sin

tan = sin / cos

( cot + tan ) sin = sec

LHS

= ( cot + tan ) sin

= ( ( cos / sin ) + ( sin / cos ) ) sin

= ( ( cos sin ) / sin ) + ( sin² / cos )

= cos + ( sin² / cos )

LCM = cos

= ( cos² / cos ) + ( sin² / cos )

= ( cos² + sin² ) / cos

Identity : -

cos² + sin² = 1

= 1 / cos

= sec

= RHS

Hence proved.
