Answer:

$\sin 68^{\circ}=\frac{28}{x}$

Step-by-step explanation:

In any triangle, the sine of an angle is equal to its opposite side divided by the hypotenuse, or longest side, of the triangle (o/h).

Therefore, we have:

$\boxed{\sin 68^{\circ}=\frac{28}{x}}$

Is (11,9), (11,5), (9,3) a function

Marina86 [1]

Answer:

$\huge{ \boxed{ \sf{No}}}$

✑ Question :

Is ( 11 , 9 ) , ( 11 , 5 ) , ( 9 , 3 ) a function ?

No , it's not a function.

✎ Reason :

This is not a function because one element 11 of set A is associated to elements 9 and 5 of set B.

♨ Explore about function :

↪ Function is a special type of relation. It is the refinement of relation. In a relation from A to B , every element of set A should have only one ( distinct ) image in B to be a function. In other words , if no two different ordered pairs have the same first component , then it is a function.

During ski season,the owner of ski shop has determined that the number of customers in a day is greater then or equal to 50 more

Scilla [17]

The question is incomplete. Here is the complete question:

During ski season,the owner of ski shop has determined that the number of customers in a day is greater than or equal to 50 more then the temperature(Fahrenheit) . Write an inequality for the problem and determine the constraints on the variables.

Answer:

$N\geq T+50$

Step-by-step explanation:

Let the number of customers be 'N' and the temperature in Fahrenheit be 'T'.

Given:

Number of customers is related to temperature in Fahrenheit as:

Number of customers is greater than or equal to 50 more than the temperature in Fahrenheit. This means,

$N\geq T+50$

Now, since 'N' represents number of customers and number can never be a negative quantity. So, the only constraint for this inequality is that the number of customers must be greater than or equal to 0.

So, $N\geq 0$
