Algebra 2 review 1. what is the equation, in standard form, of a parabola that models the values in the table? x | -2 0 4f(x) | 2.5 1.5 -60.5(i used stat on the calculator, and found the answer, nevermind on this one)2. simplify the expression.

Step-by-step explanation:

For #2, remember that , so Also, (a+b)(a-b), where a and b are any numbers, (a+b)(a-b)=. Now, to simplify, or radicalize, a number with surds in the denominator, you have to multiply the denominator by its conjugate. If there is a complex number , where a and b are any numbers, the conjugate is always . Lets apply these rules. The conjugate of 4+6i is 4-6i, so do this:

Our answer is (28-3i)/(26)!

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.
