The vertices of triangle ABC are A (1,5), B (3,9), and C (5,3). The vertices of triangle DEF are D (-3,3), E (-2,5), and F (-1,2). Which conclusion is true about the triangles? A. The ratio of their corresponding sides is 1:3.

B. They are congruent by definition of congruence in terms of rigid motions.

C. The ratio of their corresponding angles is 1:3.

D. They are similar by definition of similarity in terms of a dilation.

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a

step-by-step explanation:

mark brainliest!

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
