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.

When converting from inches to feet , the measurement in inches,m, of an object varies directly with its measurement in feet, f,
aleksandr82 [10.1K]

Answer:

m = 12f

Or

m/12 = f

Step-by-step explanation:

The conversion from inches to feet involves a constant factor of variation which is 12. Inches is a smaller unit while feet are obtained by dividing the inches with 12.

As we know,

1 foot = 12 inches

Given in the question:

m = measurement in inches

and

f= measurement in feet

Hence the equation will be:

m = 12f

Or

m/12 = f ..

The spinner below is spun three times, find all possible outcomes. the spinner has 12 numbers
Simora [160]

For the spinner with 3 sectors, the total number of outcomes for 3 spins is 27.

<h3></h3><h3>What is the combination?</h3>

A combination is a mathematical technique that determines the number of possible arrangements.

Let's we have to define

A, B, and C, as the regions in the spinner.

So, we spin it 3 times, and for each of these times there are 3 outcomes, so the outcomes will be of the form:

The outcome of spin 1, the outcome of spin 2, outcome of spin 3.

The total number of  different outcomes will be:

3^3 = 27
