Given: A high school has 2 times as many trumpet players as tuba players.
Let x be the number of tuba players , then the number of trumpet is given by :-
The number of trumpet=2x
Now, for 1 tuba player , the number of trumpet=
Hence, the trumpets to represent the number of trumpet players for every tuba player= 2.

Answer:
(x - 3)² + (y + 9)² = 25
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
Given area = 25π , that is
πr² = 25π ( divide both sides by π )
r² = 25 ( take the square root of both sides )
r = = 5
With centre (h, k) = (3, - 9 ) and r = 5 , then
(x - 3)² + (y - (- 9) )² = 5² , that is
(x - 3)² + (y + 9)² = 25
