F(x)=3x^2-18x+27<br><br>can you solve this?
Alika [10]
What do you mean by "solve this?"  Until you set f(x) = to some constant number, you don't have an equation and thus can't expect to find solutions.

Why don't we take <span>3x^2-18x+27 and set it = to 0, and only then try to solve this equation?

</span><span>3x^2-18x+27 = 0.  Dividing both sides by 3, we get x^2 - 6x + 9= 0, which can be factored as

(x-3)^2 = 0.  Taking the sqrt of both sides, we get x-3 = 0.  Actually, there are 2 roots:  3 and 3.  Again, this statement is true only if we set </span><span>3x^2-18x+27 = to 0.</span>

Given that sin θ = 3/4 and θ is in Quadrant II:<br> Find cos θ.
julsineya [31]

this is for the Sin

*Remember that sin = opposite / hypotenuse*

a² + b² = c² (where a and b are legs and c is the hypotenuse)

From the picture, you can see:

a = 3

c = 4

Plug these into the equation and solve for b.

* a² + b² = c² *

step 1: 3² + b² = 4²

step 2: 9 + b² = 16

step 3: b² = 16 - 9

step 4: b² = 7

step 5: √(b²) = √7

step 6: b = ± √7

FOR COS:

From the picture,  you can see that if θ is in quadrant II, b has to be negative.

b = -√7 = adjacent

Remember that cos θ = adjacent / hypotenuse.

cos θ = adjacent / hypotenuse

cos θ = (-√7 / 4)

Answer:

Step-by-step explanation:

i assume you need x

-3+9x=-6

add 3 on both sides

9x=-6+3

9x=-3

x=-3/9=-1/3
