Answer:
The correct option is c.
discrete data set because there are a finite number of possible values.
Step-by-step explanation:
A discrete data set are data set that can be counted , they are not represented in intervals.
I hope it helps :DD You can leave a comment if you do not understand :)
we know that
the area of the complete square is equal to

where
b is the length side of the square

so

m²
the area of one corner is equal to the area of a triangle

so
the area of
corners is equal to

the area A of the resulting figure as a function of x is equal to
area of the square minus the area of
corners
m²
the answer is
m²
H(t)=-16t^2+15t+12
(e)
maximum height is reached when h'(t)=-32t+15=0, or tm=15/32 seconds.
maximum height reached = h(tm)=h(15/32)=-16(15/32)^2+15(15/32)+12
=993/64 ft
=15.516 ft.
(f) when Greg reaches water, h(t)=0=-16t^2+15t+12
Solve for t using quadratic formula,
t=[-15+/- sqrt(15^2+4*12*16)]/(2*-16)
=-0.516s or 1.4535s.
Reject negative root so
Greg reaches water at t=1.4535 seconds.
