The drama club is planning a field

Inessa [10]

Answer:

$\frac{2}{3}s+8=48$ .

Step-by-step explanation:

If we indicate the amount of students in the drama club as"s", we know that $\frac{2}{3}s$ is attending to the trip.
We also know that there are will be 8 teachers in the trip as well.
If the total amount of persons that will go on the trip reachs 48, which is the sum of 8 teachers and the $\frac{2}{3}s$ of the students: $\frac{2}{3}s+8=48$ .

Then, the equation that describes the situation is $\frac{2}{3}s+8=48$ . If we subtract 8 from both sides of the equation, and then we have $\frac{2}{3}s=40$ , which means that s=60.

HELP ASAP PLEASE! THANKS!!!

Using it's concept, the range of the function is given by:

y ≥ 1

<h3>What is the range of a function?</h3>

The range of a function is composed by the set that contains all output values for the function. Considering the graph of the function, the range is given by all the values of y, which compose the vertical axis of the graph.

Looking at this graph, the function assumes values of 1 and greater, hence the range of the function is given by:

y ≥ 1.

Determine the exact values of all three trigonometric functions of the angle 4.25pi

Margarita [4]

Answer:

Sin (4.25π)= 0.7071

Cos(4.25π)= 0.7071

Tan(4.25π)= 1

Step-by-step explanation:

$\pi=180º (half circumference)\\ 2\pi= 360º (complete circumference)\\ 4\pi= 720º (2 complete cincumference\\ 4.25\pi= 720º + 45º (2 complete circumference + 45º)$

Sin, Cos and Tan of 45º angle is the same with 1,2 or more circumferences.

So the result is the same for 45º angle.

So:

$Sin (45º) = \frac{\sqrt{2} }{2}\\Cos (45º) = \frac{\sqrt{2} }{2}\\ Tan(45º) = 1$
