Answer:

t = 1, but please check to see if I correctly interpreted your formatting.

Step-by-step explanation:

The format of the question is too confusing.

I'll assume this is the equation to be solved:

16−2t=t+9+4t

16−2t=t+9+4t

16-9 = t + 2t + 4t

7 = 7t

t = 1

A circular plate has a radius of 13 centimeters.

butalik [34]

To solve the problem, we need to get the formula for area of a circle -
Area = pi * r^2; r= radius
= 3.14 * (13cm)^2
= 3.14 * 169cm^2 or 3.14 * 13^2cm^2
= 530.66cm^2
Therefore, the area of the circular plate is 530.66cm^2

The values would be

sin2x = -3/5

cos2x = -4/5

tan2x = 3/4

What are double angles in trigonometry?

The double angle formulas are used to find the values of double angles of trigonometric functions using their single angle values. For example, the value of cos 30° can be used to find the value of cos 60°. Also, the double-angle formulas can be used to derive the triple-angle formulas.

Given: tanx = -3

Now as we know,

$sin2x=\frac{2tanx}{1+tan^2x}\\\\sin2x=\frac{2(-3)}{1+(-3)^2}\\\\sin2x=\frac{-6}{10}\\\\sin2x=\frac{-3}{5}$

Now

$cos2x=\frac{1-tan^2x}{1+tan^2x}\\\\cos2x=\frac{1-(-3)^2}{1+(-3)^2}\\\\cos2x=\frac{1-9}{1+9}\\\\cos2x=\frac{-8}{10}\\\\cos2x=\frac{-4}{5}$

And similarly, we can find the value of tan2x, as

tan2x = sin2x/cos2x

= (-3/5)/(-4/5)

= 3/4

Hence,

The values would be

sin2x = -3/5

cos2x = -4/5

tan2x = 3/4
