Answer:
27.5
Step-by-step explanation:
<DAC is an inscribed angle that subtends a half circle, so m<DAC = 90°.
Triangle DAC is a right triangle.
CD = 30
AD = 12
(AC)² + (AD)² = (CD)²
(AC)² + 144 = 900
AC = √756
AC = 27.5
8 1/9 because 9 times 8 is 72 and 73-72=1 so 8 1/9

Answer:
number of units for cost to be minimum=150
Step-by-step explanation:
y=2x^2-600 x+49000
dy/dx=4x-600
dy/dx=0 gives 4x-600=0
4x=600
x=150
d^2y/dx^2=4x
at x=150,d^2y/dx^2=4*150=600>0
so y is minimum at x=150
Answer: 30 $15 tickets and 20 $35 tickets
Step-by-step explanation:
.X%2BY=50
2.15X%2B35Y=1150
From eq. 1,
15X%2B15Y=750
Subtract from eq. 2,
15X%2B35Y-15X-15Y=1150-750
20Y=400
Y=20
Then,
X%2B20=50
X=30
30 $15 tickets and 20 $35 ticket
Hope it helps
