A dolphin is 45 feet underwater and ascends at a constant rate for 18 seconds until it reaches the surface.

Identify and interpret the intercepts, then use the intercepts to graph the line.

The y-intercept is
which means that the dolphin's elevation it begins to ascend is
feet.

The x-intercept is
which means that it takes the dolphin
seconds to reach th

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

answer
