5 - 3tan3x = 0 trên -π< x < π.

serious [3.7K]

Answer:

x = 0.343

Step-by-step explanation:

We want to solve:

5 - 3tan(3x) = 0

such that:

-π< x < π

where π = 3.14

then:

-3.14 < x < 3.14

Let's solve the equation:

5 - 3tan(3x) = 0

-3tan(3x) = -5

tan(3x) = -5/-3 = 5/3

Now we can use the inverse tan function, Atan(x).

Remember that:

Atan( tan(x) ) = tan( Atan(x)) = x

Then if we apply that function to both sides, we get:

Atan( tan(3x)) = Atan(5/3)

3x = Atan(5/3)

x = Atan(5/3)/3 = 0.343

Karen operates a hot dog stand. On Wednesday she used 9 1/3 bags of hot

trapecia [35]

<h2>Explanation:</h2>

We know that Karen operates a hot dog stand. So we have:

On Wednesday:

$\text{She used} \ 9 \frac{1}{3} \ \text{bags of hot dog buns.}$

On Thursday:

$\text{She used} \ \frac{1}{3} \ \text{as many hot dog buns as on Wednesday}$

Therefore, if x is the amount of hot dog buns she used on Thursday, then:

$x=\frac{1}{3}(9\frac{1}{3}) \\ \\ x=\frac{1}{3}\times 9+\frac{1}{3}\times \frac{1}{3} \\ \\ x=\frac{28}{9}$

Therefore, on Thursday she used 28/9 bags of hot dog buns.
