Se simplifica inicialmente la fórmula en términos de las funciones trigonométricas fundamentales (Initially, the formula is simplified in terms of fundamental trigonometric functions):
![(\sec 245^{\circ} + \tan 45^{\circ} )\cdot \cot 37^{\circ} - 2\cos 60^{\circ}](https://tex.z-dn.net/?f=%28%5Csec%20245%5E%7B%5Ccirc%7D%20%2B%20%5Ctan%2045%5E%7B%5Ccirc%7D%20%29%5Ccdot%20%5Ccot%2037%5E%7B%5Ccirc%7D%20-%202%5Ccos%2060%5E%7B%5Ccirc%7D)
![\left(\frac{1}{\cos 245^{\circ}}+\frac{\sin 45^{\circ}}{\cos 45^{\circ}} \right)\cdot \left(\frac{\cos 37^{\circ}}{\sin 37^{\circ}} \right) - 2\cdot \cos 60^{\circ}](https://tex.z-dn.net/?f=%5Cleft%28%5Cfrac%7B1%7D%7B%5Ccos%20245%5E%7B%5Ccirc%7D%7D%2B%5Cfrac%7B%5Csin%2045%5E%7B%5Ccirc%7D%7D%7B%5Ccos%2045%5E%7B%5Ccirc%7D%7D%20%20%5Cright%29%5Ccdot%20%5Cleft%28%5Cfrac%7B%5Ccos%2037%5E%7B%5Ccirc%7D%7D%7B%5Csin%2037%5E%7B%5Ccirc%7D%7D%20%5Cright%29%20-%202%5Ccdot%20%5Ccos%2060%5E%7B%5Ccirc%7D)

X= -2 because I love school soooo much
Hello!
In a function, each input has only one output. In A, three has two outputs, 4 and 5, so A is not a function.
In B, you can use something called the vertical line test to see if each x value has one y value as an output. You move an imaginary vertical line across the graph, and if it intersects with two points it is not a function. If we do this on our graph, it will not intersect two points. Therefore, B is a function.
In C, we can see that each input has one output, or there are all different inputs, so C is a function.
For D we can use that vertical line test again. It intersects both the points (-1,1) and (-1,6) so D is not a function
Our final answers are B and C.
I hope this helps!
Let the shortest side be = a, then side b = 2·a and side c = (b + 24)
We are given that a + b + c = 84
Substituting for b and c
a + 2·a + (a + 24) = 84
4·a + 24 = 84
4·a = 84 - 24 = 60
a = 60/4 = 15 feet
b = 2·15 = 30 feet
c = 15 + 24 = 39 feet
sorry if i am wrong
Answer:
s = 14
Step-by-step explanation:
Step 1: Combine like terms.
Step 2: Multiply both sides by 2/3.
