Answer:

  -√3

Step-by-step explanation:

We note that this matches the form for the tangent of the difference of two angles:

  tan(α-β) = (tan(α) -tan(β))/(1 +tan(α)tan(βb))

Here, we have α = 25π/24 and β = 3π/8. Then the angle difference is ...

  α -β = π(25/24 -3/8) = π(2/3)

The value you seek is ...

  tan(2π/3) = -√3

how can you tell if a function is linear or nonlinear from a table​

Answers

You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference . This table is linear.

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

We know that the sine function is a ratio of opposite side and hypotenuse.

The cosine function is a ratio of Adjacent side and hypotenuse.

Let us find the product of sin 30° and sin 60°

=sin 30°.sin 60°

=1/2.√3/2

=√3/4

Now we know that  cos 60° is 1/2 and  cos 30° is √3/2

Product cos 60° and cos 30°

cos 30°.cos 60°=1/2.√3/2

=√3/4

Hence, the product of sin 30° and sin 60° is same as the product of cos 30° and cos60°.

[tex]x=2[/tex]

Step-by-step explanation:

Since the scale is in equilibrium, both sides must be equal. Therefore, we have the following equation:

[tex][\text{Left Side} ]3x+3=[\text{Right Side}]9[/tex]

Solving for [tex]x[/tex]:

[tex]3x+3=9,\\3x=6,\\x=\boxed{2}[/tex]

Answer:x=2

Step-by-step explanation: try to first set up an equation. First we can see the scale is balanced so we know each side is equal to each other. You have 3 x boxes and 3 circles so our first side will be 3x+3. Now let’s move onto the second side. It has 9 circles so 3x+3=9. Now let’s solve!

Subtract 3

3x=6

Now divide by 3
