I doesn't seem right to me. You can use an online calculator where all you do is input the values. Search for "parabolic motion calculator" or something along those lines. Hope it helps.
Answer:
Yes,
Step-by-step explanation:
You take 64 miles for 2 gallons and divide it by 2. And it leads up to 32 miles and 1 gallon. Now you divide that by 2 again and get 16 miles and 1/2 gallon. So, to check that you can take 16+16 and you get 32 and take 32+32 and you get 64.
Answer: Alternate exterior angles
Step-by-step explanation:
The angles formed by the angle bisector BF are ∠FBA and ∠FBC.
The step in which the mistake was made is<u> step 3; Then, she placed the compass on point C and drew an arc on the interior of ∠ABC which intersects the previous arc</u>.
Reasons:
The steps to draw an angle bisector are;
Place the compass at the vertex of the angle and draw an arc intersecting the the two rays forming the angle at points <em>D</em> and <em>E</em>
Place the compass at point <em>D</em> and draw an interior arc to the given angle
Place the compass at point <em>E</em> and draw a second interior arc intersecting the previous arc
The point of intersection of the two arcs can be labelled <em>F</em> and joined to the vertex of the given angle to complete the angle bisection
Therefore, the step in which the mistake was made is; Step 3 where the compass is placed at point <em>C</em> rather than point <em>E </em>to draw the second arc of the angle bisector

Answer:
The volume of the ball with the drilled hole is:
Step-by-step explanation:
See attached a sketch of the region that is revolved about the y-axis to produce the upper half of the ball. Notice the function y is the equation of a circle centered at the origin with radius 15:
Then we set the integral for the volume by using shell method:
That can be solved by substitution:
The limits of integration also change:
For x=5: 
For x=15: 
So the integral becomes:
If we flip the limits we also get rid of the minus in front, and writing the root as an exponent we get:
Then applying the basic rule we get:
Since that is just half of the solid, we multiply by 2 to get the complete volume:
