Sin x = 3/10 find sin 2x

Mathematics
1 answer:
Ann [662]3 years ago
3 0

Answer: 34.92

Step-by-step explanation:

Sin x             = ³/₁₀

Sin x              = 0.30

Since we are determining the value of x,

x                    = sin⁻1 (0.30), this is called the inverse of sin or arc of sine, this could be calculated using your calculator by pressing the second function or the shift on the calculator and then press the sin⁻1

Therefore

x                  =    17.46

2x                =    17 46 x 2

                   =    34. 915

                   ≅  34. 92

The value of a professional basketball player's autograph rose 20% in the last year. It is now worth $324.00. What was it worth
Helga [31]

So what you want to find is: what number times 120% is $324.00. (IT is 120% percent because it is the original <em>plus</em> the new percent) Simply set it up like so:

SN *120% = $324.00

Now turn the percent into a decimal:

SN * 1.20 = $324.00

Now divide $324.00 by 1.20

SN = $270

The original value of the basketball player's autograph was 270 dollars!

Hope that helps!

3. Find the missing side lengths. Leave your answers as radicals in simplest form. Show your work to support
7nadin3 [17]

Answer: b=2(square root of 2) and a=4

Step-by-step explanation:

Since this is a 45-45-90 triangle we know that side b is equal to b=2\sqrt{2}.

In a 45-45-90 triangle, the hypotenuse is equal to x\sqrt{2} this means in order to find missing side length a, we have to multiply (2\sqrt{2})(\sqrt{2}) this will give us 4

so the missing side lengths are, b=2\sqrt{2} and a=4
