Answer:
44m
Step-by-step explanation:
A =
r² = 154
= 22/7 * r² = 154
= r² = 154 * 7/22
= r² = 49
= r = √49
= r = 7m
Perimeter of circle = 2
r
= 2 * 22/7 * 7
= 44/7 * 7
= <u>44 m</u>

Given:
maximum seating 76,867 fans
cost of tickets $161
revenue: f(x) = 161x
y = 161x
domain is the x values
range is the y values
using the formula: y = 161x where x = 76,867
y = 161(76,867)
y = 12,375,587
domain is 76,867
range is 12,375,587
Option B is the correct answer
Answer:
x = -1 and y = 1/2
Step-by-step explanation:
Let u = 1/x, and v = 1/y
Then the pair of equations
-3/x + 4/y = 11
1/x - 2/y = -5
Can be written as
-3u + 4v = 11 .................................(1)
u - 2v = -5......................................(2)
From (2)
u = 2v - 5 .......................................(3)
Substituting (3) into (1)
-3(2v - 5) + 4v = 11
-6v + 15 + 4v = 11
-6v + 4v = 11 - 15
-2v = -4
v = 4/2 = 2
Substituting this value of v in (3)
u = 2v - 5
u = 2(2) - 5
= 4 - 5
= -1
That is
u = -1, v = 2
Since u = 1/x, and v = 1/y, we have
1/x = -1
=> x = -1
And
1/y = 2
=> y = 1/2
Therefore
x = -1 and y = 1/2
