If sin(32)=x , then sin(4) cos(4) cos(8) cos(16)=..............
svp [43]

If sin 32 is equal to x, then sin 4 · cos 4 · cos 8 · cos 16 is equal to x/8 by using <em>double angle trigonometric</em> functions.

<h3>How to simplify an expression by trigonometric expressions</h3>

<em>Trigonometric</em> expressions are formulas that utilize <em>trigonometric</em> functions. <em>Trigonometric</em> functions are a kind of <em>trascendental</em> functions, that is, functions that cannot be described in <em>algebraic</em> terms.

In this question we must simplify a given expression by using the following trigonometric formula:

<em>sin 2x = 2 · cos x · cos x</em>   (1)

Now we proceed to expand the expression given:

x = sin 32

x = 2 · sin 16 · cos 16

x = 4 · sin 8 · cos 8 · cos 16

x = 8 · sin 4 · cos 4 · cos 8 · cos 16

Thus,

sin 4 · cos 4 · cos 8 · cos 16 = x/8

If sin 32 is equal to x, then sin 4 · cos 4 · cos 8 · cos 16 is equal to x/8 by using <em>double angle trigonometric</em> functions. \blacksquare

Pedro and John are going on a field trip with school. Together the boys have $62 to spend on the trip. If Pedro has $15 more tha
Volgvan

Answer:

<h2>John has $23.5</h2>

Step-by-step explanation:

Step one:

we are told that their joint amount is $62

let John's amount be x

and Pedro's amount be y

so that y=x+15

Step two:

The equation to represent the situation is

62=x+(x+15)

open the bracket and solve for x we have

62=x+x+15

62=2x+15

2x=62-15

2x=47

divide both sides by 2

x=47/2

x=23.5

<u>John has $23.5</u>

djverab [1.8K]
The greatest common factor of 24 and 18 is 6

24/6 = 4 golf balls
18/6 = 3 paddles

so she can sell 6 packages, with each one containing 4 golf balls and 3 paddles.
