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.

There is only one solution since 3x-1 must equal 0

3x = 1

x = 1/3

In which quadrants do solutions for the inequality y is less than or equal to two sevenths times x plus 1 exist?
hram777 [196]

Answer:

y will be in every single quadrant

Step-by-step explanation:

So we have the equation y\leq \frac{2}{7} x+1  first we will have to look at the equation. It says that y is less than or equal to \frac{2}{7} x+1 since y is less than \frac{2}{7} x+1 the only place the shaded area where y can be is under the line that is drawn be the equation. When the equation is graphed the y-intercept will be on positive 1 it since slope is rise over run it will look something like the file attached to this. so under the line you can see every single quadrant so that is why it would be that way
