Ateenager learning about computers and programming for the first time writes a simple program meant to disrupt the function of his sister’s computer. while she’s hanging out with friends at the mall, he enters his sister’s ip address, launches the program, and waits to see what will happen. the teenager is an example of

The correct answer is: Script kiddie.

Explanation:

In programming and hacking, a script kiddie or skiddie is a non-qualified individual that uses scripts or software developed by others to attack computer systems, networks, and website failures. These individuals are taken for incompetents within the programming community.

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.

i guess you could put raise the economic balance
