Step-by-step explanation:
hope it helpe...............
positive integers are integers greater than zero
C=2πr, if r=7 then:
C=2π7
C=14π in
C≈43.98 in (to nearest hundredth of an inch)
Apparently the people who gave you the answer choices don't know how to round correctly :)
I'd go with D) 43.96 inches as it is somewhat close to the correct answer LOL
we have
we know that
the vertex form of the vertical parabola equation is equal to
where
(h,k) is the vertex of the parabola
To find the equation rewritten in vertex form let's factor the equation
<u>Factor the leading coefficient </u>
<u>Complete the square. Remember to balance the equation by adding the same constants to each side</u>
<u>Rewrite as perfect squares</u>
therefore
the answer is
