The area of the circle is about 28.26
Area of circle= pi(radius squared)
3 squared = 9
9 x pi (3.14) = 28.26
Or 28.26 if you’re using the unrounded version of pi
Ans: 0. fraction is equal to 0 then 0×1000=0
Answer:
p = 
Step-by-step explanation:
Given
= 
( cross- multiply )
20(p - 4) = 5p ← distribute left side
20p - 80 = 5p ( subtract 5p from both sides )
15p - 80 = 0 ( add 80 to both sides )
15p = 80 ( divide both sides by 15 )
p = 
=
Answer: its 1/9
All you do is divide them by 4
4 divided by 4=1
36 divided by 4=9
Also can I get brainly thing?
For Part A, what to do first is to equate the given equation to zero in order to find your x intercepts (zeroes)
0=-250n^2+3,250n-9,000 after factoring out, we get
-250(n-4)(n-9) and these are your zero values.
For Part B, you need to square the function from the general equation Ax^2+Bx+C=0. So to do that, we use the equated form of the equation 0=-250n^2+3,250n-9,000 and in order to have a positive value of 250n^2, we divide both sides by -1
250n^2-3,250n+9,000=0
to simplify, we divide it by 250 to get n^2-13n+36=0 or n^2-13n = -36 (this form is easier in order to complete the square, ax^2+bx=c)
in squaring, we need to apply <span><span><span>(<span>b/2</span>)^2 to both sides where our b is -13 so,
(-13/2)^2 is 169/4
so the equation now becomes n^2-13n+169/4 = 25/4 or to simplify, we apply the concept of a perfect square binomial, so the equation turns out like this
(n-13/2)^2 = 25/4 then to find the value of n, we apply the square root to both sides to obtain n-13/2 = 5/2 and n is 9. This gives us the confirmation from Part A.
For Part C, since the function is a binomial so the graph is a parabola. The axis of symmetry would be x=5.
