Guillermo is a professional deep water free diver.

His altitude (in meters relative to sea level),x seconds after diving, is modeled by

g(x)= 1/20x(x-100)

How many seconds after diving will Guillermo reach his lowest altitude?

100 seconds

Step-by-step explanation:

Guillermo's altitude (height) is given as:

His lowest altitude will be when he is at the sea floor, at g(x) = 0.

Hence, the time (x), when g(x) = 0 is:

Multiplying by 20:

Divide both sides by x:

x = 100 secs

He will be at his lowest altitude in 100 seconds.

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
