Answer:

1. C

2. B

Step-by-step explanation:

1. Remember your rules for rotating. When you're rotating 180 degrees (x,y) --> (-x,-y), this means that you flip your signs. So for example, (10, -3) turns into (-10, 3) the only thing you're changing are your signs.

2. Once again, remember your rules for rotating. When rotating 90 degrees clockwise flip your x and y, and change the sign of x. So (x,y) --> (y, -x). So for example, (13, 5) --> (-5, 13)

At the end of the day, this all comes down to knowing your rules and practicing. I promise you it gets easier. Good luck!

Find all the zeros of the equation
lapo4ka [179]

Divide both sides by -3, and replace x^2 with y. Then

-3x^4+27x^2+1200=0\iff y^2-9y-400=0

Factorize the quadratic in y to get

y^2-9y-400=(y+16)(y-25)=0\implies y=-16,y=25

which in turn means

x^2=-16,x^2=25

But x^2\ge0 for all real x, so we can ignore the first solution. This leaves us with

x^2=25\implies x=\pm\sqrt{25}=\pm5

If we allow for any complex solution, then we can continue with the solution we ignored:

x^2=-16\implies x=\pm\sqrt{-16}=\pm i\sqrt{16}=\pm4i

Answer:

B. 1/9

Step-by-step explanation:

The positive square root of "x^2 - 4x + 4" is "x - 2". That value is already given to you, 1/3. Just square 1/3 to get 1/9.
