A dynamic blast blows a heavy rock straight up with an initial velocity of 49m/s. the function h(t) represent the height of the rock after t seconds.
A. How high does the rock go ?
B. When does the rock hit the ground again ?( Use factoring )
C. Will the rock reach a height of 120 m ? (explain using the discriminant)
D. When does the rock reach a height of 100 m ? (use the quadratic formula ) ( approximate
your answers to two decimal places )
E. Sketch the graph of the parabola include intercepts , vertex and and and at h=100m.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
