Answer:
you will add $1.53 to every bracelet you make
Step-by-step explanation:
figure out what 85 percent of 1.80 is and then add that to 1.80 for the total price
85% x 1.8 = 1.53 (markup ammount)
1.80 + 1.53 = 3.33 (total cost)

Step-by-step explanation:
a) The equation must be rearranged into a form with one fundamental trigonometric function first:
![\sqrt{3}\cdot \csc x - 2 = 0](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D%5Ccdot%20%5Ccsc%20x%20-%202%20%3D%200)
![\sqrt{3} \cdot \left(\frac{1}{\sin x} \right) - 2 = 0](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D%20%5Ccdot%20%5Cleft%28%5Cfrac%7B1%7D%7B%5Csin%20x%7D%20%5Cright%29%20-%202%20%3D%200)
![\sqrt{3} - 2\cdot \sin x = 0](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D%20-%202%5Ccdot%20%5Csin%20x%20%3D%200)
![\sin x = \frac{\sqrt{3}}{2}](https://tex.z-dn.net/?f=%5Csin%20x%20%3D%20%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D)
![x = \sin^{-1} \frac{\sqrt{3}}{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Csin%5E%7B-1%7D%20%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B2%7D)
Value of x is contained in the following sets of solutions:
, ![\forall i \in \mathbb{N}_{O}](https://tex.z-dn.net/?f=%5Cforall%20i%20%5Cin%20%5Cmathbb%7BN%7D_%7BO%7D)
, ![\forall i \in \mathbb{N}_{O}](https://tex.z-dn.net/?f=%5Cforall%20i%20%5Cin%20%5Cmathbb%7BN%7D_%7BO%7D)
b) The equation must be simplified first:
![\cos x + 1 = - \cos x](https://tex.z-dn.net/?f=%5Ccos%20x%20%2B%201%20%3D%20-%20%5Ccos%20x)
![2\cdot \cos x = -1](https://tex.z-dn.net/?f=2%5Ccdot%20%5Ccos%20x%20%3D%20-1)
![\cos x = -\frac{1}{2}](https://tex.z-dn.net/?f=%5Ccos%20x%20%3D%20-%5Cfrac%7B1%7D%7B2%7D)
![x = \cos^{-1} \left(-\frac{1}{2} \right)](https://tex.z-dn.net/?f=x%20%3D%20%5Ccos%5E%7B-1%7D%20%5Cleft%28-%5Cfrac%7B1%7D%7B2%7D%20%5Cright%29)
Value of x is contained in the following sets of solutions:
, ![\forall i \in \mathbb{N}_{O}](https://tex.z-dn.net/?f=%5Cforall%20i%20%5Cin%20%5Cmathbb%7BN%7D_%7BO%7D)
, ![\forall i \in \mathbb{N}_{O}](https://tex.z-dn.net/?f=%5Cforall%20i%20%5Cin%20%5Cmathbb%7BN%7D_%7BO%7D)
Answer: Looks like choice B would be the best description of an output.. Usually, output refers to the dependent value of a function rule. It is also correct that the y coordinate of ordered pairs, graphed points, and in a function table.
Step-by-step explanation: I got this from a friend, hope it helps!
X^2 - 7x + 12 = 0
x^2 - 4x - 3x + 12 = 0
x (x - 4) -3 ( x - 4) = 0
(x - 4) (x - 3) = 0
x = 3 , 4
Check the answer by plugging in 3 and 4 for x, if the equation equals zero then you have your answer.
