The parabola y=x^2 is shifted up by 7 units and to the left by 1 unit.

Step-by-step explanation:

f (x) + n - shift up by n units

f (x) - n - shift down by n units

f (x - n) - shift to the right by n units

f (x + n) - shift to the left by n units

We have y = x² → f(x) = x². Shifted up by 7 units and to the left by 1 unit:

use (a + b)² = a² + 2ab + b²

Step-by-step explanation:

I did it on Khan and it was right.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

they disappear if your absent from to long. i found out that the hard way.
