Hey John I believe u made a mistake on the last question since the equation is c^2=a^2+b^2 u should subtract AD^2 with the hypotenuse. Another way to be sure is the length of hypotenuse is always the longest

see carefully. the value of c is 5 in the equation of the parabola but, in case of the intersection, it's 4.

I'm taking august 26 sat and I'm scared :( I have a 1430, but I really want a 1550. For past sat tests I've been using for practice, I've been scoring 1530-1580, so maybe I'm ok. But are August 26 exams historically easier or more difficult? I've never taken one in August, and I'm taking one in a new testing center.

You answered the last question wrong, as at the very end you did 8^2 + 20^2 = AD^2 which in the right triangle would be equivalent to a^2 + c^2 = b^2. The correct answer would have been 20^2 - 8^2 = AD^2 leaving you with 336 as x.

@JayAhuja014

6 ай бұрын

to get the y^2-6 into the (y-k)^2 form, you complete the square on the y^2-6y. (-6/2)^2 = 9, so you add 9 to both sides and then you are able to factor y^2-6y+9 into (y-3)^2. In this question though, its asking for area, so don't bother factoring it, just complete the square and see what you get on the right side, and find the area using the radius.

He add 9 because to make the (y-3)^2 he need first to add the 9 to make the equation y^2-6y+9 so that can be a possible perfect square.

that's how 'completing the square' works for circles. To complete the square, you add 9 to the left side. To keep the equation balanced, you have to add it to the other side as well. Get the PDF and go to the blue link for more detailed explanation. You want to know this.

So if you usually et between 700-770 but have one test with a 560, ignore the 560 and assume that your real score is around a 700 give or take 20-30
