Hey there Caiiitynn.
The Y-intercept is where the line goes through the Y-Axis. In this case, its 3.

AC= √CD^2+AD^2
AC= √AB^2+BC^2
Those two are true
See explanation in photo below
Good luck
It will have 15 protons because the atomic number will always equal the number of protons and vice versa
Volume of cone= 1/3πr^2h
8842.24 m^3= 1/3πr^2h
1/3*3.14*33*r^2= 8842.24m^3
r^2 = 8842.24*3/3.14*33
r^2= 26526.72/103.62
r^2 = 256
r= √256
r= 16m
Hope it helps. Please mark brainliest.
