Classify the quadratic form below. Then make a change of variable. x= Py, that transforms the quadratic form into one with no cross-product term. Write the new quadratic form 8??4x1x2 + 5x2 Choose the most precise classification for the quadratic form A. Positive definite
B. Negative semidefinite
C. Indefinite
D. Negative definite
E. Positive semidefinite

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

answer: i dont know but if you try hard you will get it right : )
