30.
3/4 is equal to 75%, so take 75% of 40 by multiplying .75 by 40 to get 30
Answer:
The radius of the sphere is 
Step-by-step explanation:
we know that
The volume of a sphere is equal to
In this problem we have
substitute and solve for r
simplify
We see that the points of the graph of the function never attain a y-value of 0. Thus f is never equal to 0 for real numbers, hence we can disqualify all the necessary answers already (only answer not against this is 2). Nevertheless, we can show that this is the right answer. The graph is called a parabola, so it is represents a second order polynomial. These polynomials have either 2 real or 2 complex solutions. Since this does not have real solutions (at the lowest point of that polynomial the y-value is 4) the correct answer is b).
Y=4x+2. To get slope you use 6-2/1-0. Which gives you 4. You then put that in point slope form.
