1. An arrow is shot from the top of a platform. The path of the arrow can be modelled by the relation h = -0.005(t - 26)2 + 5, where h is the height of the arrow in metres and
f is the time in seconds after the arrow was shot.

(a) State the vertex of the parabola.

(c) How long will it take the arrow to reach
its maximum height?

(d) What is the maximum height of the arrow?

(e) Calculate the height after 10 seconds​

step-by-step explanation:

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
