Sin 300° = 2 sin 150° cos 150° use exact values to show it is true

strojnjashka [21]

Answer:

see explanation

Step-by-step explanation:

left side = sin300° = - sin60° and sin60 = $\frac{\sqrt{3} }{2}$ , thus

sin300° = - $\frac{\sqrt{3} }{2}$

right side

sin150° = sin30° = $\frac{1}{2}$ and

cos150° = - cos30° = - $\frac{\sqrt{3} }{2}$ , thus

2sin150°cos150°

= 2 × $\frac{1}{2}$ × - $\frac{\sqrt{3} }{2}$ = - $\frac{\sqrt{3} }{2}$

left side = right side ⇒ True

If f(x) = x^3 find df/dx | x= -5

asambeis [7]

Answer:

Step-by-step explanation:

So we have:

$f(x)=x^3$

Take the derivative of the function. Use the power rule, which states that:

$\frac{d}{dx}(x^n)=nx^{n-1}$

Therefore:

$\frac{d}{dx}[f(x)]=\frac{d}{dx}[x^3]$

Use power rule:

$\frac{df}{dx}=3x^2$

Now, substitute in -5:

$3(-5)^2$

Square and multiply:

$=3(25)=75$

So our answer is 75.

This means that the slope of the line tangent to the point (-5,-125) on the graph x^3 is 75.

And we're done!
