I just need help set up

Vilka [71]

Answer:

Step-by-step explanation:

Set up equations (L= Lisa; M = Maria; A = April; J = Jim)

L = 12M

A = 2J

Substitute x for Maria and 6x for Jim

L = 12x

A = 2(6x) = 12x

So, you get:

Maria = x

Jim = 6x

Lisa = 12x

April = 12x

Verify this trig function. tanysiny = secy-cosy ?

avanturin [10]

$LHS\\ \\ =\tan { y } \sin { y } \\ \\ =\frac { \sin { y } }{ \cos { y } } \cdot \sin { y }$

$\\ \\ =\frac { \sin ^{ 2 }{ y } }{ \cos { y } } \\ \\ =\frac { 1-\cos ^{ 2 }{ y } }{ \cos { y } }$

$\\ \\ =\frac { 1 }{ \cos { y } } -\frac { \cos ^{ 2 }{ y } }{ \cos { y } } \\ \\ =\sec { y } -\cos { y } \\ \\ =RHS$
