Area of shaded region is 18π square unit.
<u>Step-by-step explanation:</u>
Given :- A circle with center O and radius 9 cm
To Find :- area of shaded region that is area of ABC
Solution : - BC = 9 cm
∠ABC = 80° = Ф
so, area of sector = πr²Ф / 360°
= (π×9×9×80) /360°
= 18π square unit
hence, area of shaded region is 18π square unit
2/3 = x/1...2 parts water to 3 parts juice = x parts water to 1 part juice
cross multiply
(3)(x) = (2)(1)
3x = 2
x = 2/3 parts water are needed for 1 part juice
The vertex is (1,-4).
Writing in the form specified:
g(x)=-(x-1)^2-4
Answer:
The first blank is "y", the second blank is "x", and the third blank is 1:3.
