Answer 1

Answer:

Step-by-step explanation:

a.) the maximum is just the vertex

-35/(2*-4.9)= it takes 3.5714 seconds to hit the maximum

which in height is

-4.9*3.5714^2+35*3.5714 +1= 63.5 metres

b.) for this just plug in 2

-4.9*2^2+35*2+1= 51.4 metres

c.) just plug in f(0) =1 meter

d.) find the x intercepts (using the quadratic formula)

$\frac{-35-\sqrt{35^2-4*-4.9*1}}{2*-4.9}=7.17131519096$ seconds

(there is another answer but it doesn't make sense in the context of this question)
