If sin(2x)sin(3x)=cos(2x)cos(3x), then find the smallest positive value of x. Express your answer in degrees, but without the degree symbol.
Answers
Answer:
[tex]x=18\textdegree[/tex]
Step-by-step explanation:
We are given the equation:
[tex]\sin(2x)\sin(3x)=\cos(2x)\cos(3x)[/tex]
And we want to find the smallest positive value of x such that it makes the equation true.
We can rewrite our equations as:
[tex]\displaystyle \cos(2x)\cos(3x) - \sin(2x)\sin(3x) = 0[/tex]
Recall that:
[tex]\displaystyle \cos (\alpha + \beta) = \cos \alpha\cos-\sin\alpha\sin\beta[/tex]
Therefore, by letting α = 2x and β = 3x, we obtain:
[tex]\displaystyle \begin{aligned} \cos(2x)\cos(3x) - \sin(2x)\sin(3x) & = \cos (2x + 3x) \\ \\ &= \cos 5x \end{aligned}[/tex]
Hence:
[tex]\displaystyle \cos 5x = 0[/tex]
Recall the Unit Circle. The smallest angle value for which cosine equals 0 is cos(90°). Thus:
[tex]\displaystyle 5x = 90^\circ[/tex]
Therefore:
[tex]\displaystyle x = 18^\circ[/tex]
In conclusion:
[tex]\displaystyle x = 18^\circ[/tex]

How much does Tim pay for the computer including tax? Round to the nearest cent if necessary.
Answers
Answer:
The total price with tax is 1293.59
Step-by-step explanation:
First find the tax
1195 * 8.25%
1195 * .0825
98.59
Add the tax to the original price
1195+ 98.59
1293.59
The total price with tax is 1293.59
Answer:
$1293.59
Step-by-step explanation:
8.25% of $1195 = $98.5875
$1195 + $98.5875 = $1293.5875
$1293.5875 rounded up to $1293.59
Tim payed $1293.59 for a computer.

(Type an integer or decimal rounded to the nearest tenth as needed.)
Answers
Answer:
76.7 million89.1 million75 millionStep-by-step explanation:
Let x represent the arrivals and departures at the third airport. Then the number at the first airport is x+1.7, and the number at the second airport is x+14.1. The total is ...
(x+1.7) + (x+14.1) + (x) = 240.8
3x +15.8 = 240.8
3x = 225
x = 75
x+1.7 = 76.7
x+14.1 = 89.1
The first airport has 76.7 million arrivals.
The second airport has 89.1 million arrivals.
The third airport has 75 million arrivals.
