In the figure shown, abc is a right triangle with side lengths a, b, and c, and cd is an altitude to side ab. the side lengths of triangle acd are b, h, and r, and the side lengths of triangle cbd are a, s, and h.

which proportions are true?

a) c/a = a/s and c/b = b/r

b) c/a = s/a and c/b = r/b

c) c/b = a/s and c/a = b/r

d) c/b = s/a and c/a = r/b

A

Step-by-step explanation:

In the figure shown, ABC is a right triangle with side lengths a, b, and c, and CD is an altitude to side AB. This altitude divides the triangle into two right triangles ADC and BDC. In these triangles,

So,

1. From the similarity you have

2. From the similarity you have

Hence, option A is true

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
