Evaluate : <br> \(\cos 12 \cos 24 \cos 36 \cos 48 \cos 72 \cos 84\)
NeTakaya
The answer in itself is 1/128 and here is the procedure to prove it:
cos(A)*cos(60+A)*cos(60-A) = cos(A)*(cos²60 - sin²A) 

<span>= cos(A)*{(1/4) - 1 + cos²A} = cos(A)*(cos²A - 3/4) </span>

<span>= (1/4){4cos^3(A) - 3cos(A)} = (1/4)*cos(3A) </span>

Now we group applying what we see above

<span>cos(12)*cos(48)*cos(72) = </span>
<span>=cos(12)*cos(60-12)*cos(60+12) = (1/4)cos(36) </span>

<span>Similarly, cos(24)*cos(36)*cos(84) = (1/4)cos(72) </span>

<span>Now the given expression is: </span>

<span>= (1/4)cos(36)*(1/4)*cos(72)*cos(60) = </span>

<span>= (1/16)*(1/2)*{(√5 + 1)/4}*{(√5 - 1)/4} [cos(60) = 1/2; </span>
<span>cos(36) = (√5 + 1)/4 and cos(72) = cos(90-18) = </span>
<span>= sin(18) = (√5 - 1)/4] </span>
<span>And we seimplify it and it goes: (1/512)*(5-1) = 1/128</span>

The expression (x-6)2is equivalent to
Marizza181 [45]

(x - 6) * 2

I'm assuming this is the expression that you typed out, if it isn't, please let me know in the comments :)

Use the distributive property:

= 2(x) - 2(6)

Multiply and simplify

= 2x - 12

This should be the expression that is equivalent to the original. Let me know if you need any clarifications, thanks!

Please help!! will list brainlist!!!!!

Answer:

b. 3t ≥ 36

Step-by-step explanation:

She gets $3 per three-pointer. The variable <em>t</em> stands for three-pointer. So in mathematical terms, it would be 3<em>t</em>.

She wants a minimum of 36 dollars, therefore the sign would be ≥. This means 3<em>t </em>has to be greater than or equal to 36.

So, 3<em>t</em> ≥ 36

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? Why or why not?
Dmitriy789 [7]

(g\cdot f)(x)=\dfrac{1}{x}-4

D_{g(f(x))}:x\not =0

No, since 0 doesn't belong to the domain.
