PLZZ HELP ASAP!!! 40 POINTS!!

Biology
1 answer:
SpyIntel [72]4 years ago
7 0

Answer:

8 cm/s

Explanation:

When the time is 0 s (x₁ = 0 s), the position of the rolling ball is 0 cm (y₁ = 0 cm).

When the time is 6 s (x₂ = 6 s), the position of the rolling ball is 45 cm (y₂ = 45 cm).

Using these 2 points, we can find the slope (m) of the secant line.

m = (y₂ - y₁)/(x₂ - x₁) = (45 cm - 0 cm)/(6 s - 0 s) = 8 cm/s (we round off to 1 significant figure)

Talja [164]

Answer:

A variation is different to an adaptation as a variation is a difference or variety inside a species, for example a different breed of dog such as a spaniel is a variety of the dog species, whereas an adaptation is a genetic mutation that has developed in order to help an animal survive, such as giraffes having a long neck. Adaptations continue throughout the species due to natural selection.
