Answer:
Step-by-step explanation:
Given points are :
x = -2 0 4
y=f(x) = 0 -6 78
We have to model the parabola with the help of these points
Solution:
We consider a standard equation of parabola
now, we put the points in the equation we get,
at (-2,0) is 4a-2b+c=0
at (0,-6) is c=-6
at (4,78) is 78= 16a+4b+c
now, solving these equation we get, a= 4 , b= 5 , c= -6
so the equation formed with these points is
we can see this in the graph attached.
Answer:70
Step-by-step explanation:
Okay so since there aren’t any values that r is equal to 19 plus r is equal to 19r. I’m pretty sure that’s the answer
Answer:
262 in
Step-by-step explanation:
the equation for volume of a sphere is : 
r
so replacing the number of the radius into the equation, it would look like:

r
which gives you 523.59878 in
but since it's a hemisphere, you'd divide it in half, which gives you 261.79939.
since you're rounding off to the nearest whole number, you're answer is 262 in
