Answer:
L=10pi, or 31.42
Step-by-step explanation:
Step-by-step explanation:
it means 13 tables have 6 chairs
and 7 tables have 4 chairs
so
total chairs in the cafeteria= 13×6 + 4×7 = 78+28=106
Adam took 7 pieces so subtract it from the total.
![13 - 7 = 6](https://tex.z-dn.net/?f=13%20-%207%20%3D%206)
He divided the rest to his 3 children
![\frac{6}{3} = 2](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%7D%7B3%7D%20%20%3D%202)
Each child recieved 2 candies.
Answer:
1.17
Step-by-step explanation:
Because the y-coordinates are the same in this parabola, it is a sideways-opening parabola, or one of the form
![(y-k) ^{2}=4p(x-h)](https://tex.z-dn.net/?f=%28y-k%29%20%5E%7B2%7D%3D4p%28x-h%29%20)
where p is the distance between the focus and the vertex. Our distance is 9-1 = 8, and the (h, k) of our vertex is (9, -2), therefore, the equation is
![(y+2) ^{2} =32(x-9)](https://tex.z-dn.net/?f=%28y%2B2%29%20%5E%7B2%7D%20%3D32%28x-9%29)
. Not sure how much you need to simplify this, but that's the standard form.
