Well
when x=2.25 y=6.75
y=kx
that means if you put x= 2.25 you will get y=6.75
in this relation (y=kx)
6.75= 2.25k
k=6.75/2.25 =3
the rel. is y=3x
whe x=4.2
y= 3*4.2 =12.6

Answer:
pretty sure it's -4.5
Step-by-step explanation:
idk mate, just used calculator
Answer:
167.55 units cubed
Step-by-step explanation:
Volume of a cone formula: πr^2(h/3)
r = 4, h = 10
Equation:
π(4^2)(10/3)
= π(16)(3.333333)
= 167.551608
H=-16t^2+49
find where h=0
0=49-16t^2
0=7^2-(4t)^2
difference of 2 perfect square
0=(7-4t)(7+4t)
set to zero
7-4t=0
7=4t
7/4=t
7+4t=0
4t=-7
t=-7/4
faslse, this is before the person jumps
answer is 7/4 seconds
