Y = -2x^2 + 50x + 300
-2x^2 + 50x + 300 ≥ 300
-2x^2 + 50x ≥ 0
-2x^2 ≥ -50x
x^2 ≤ 25x
x ≤ 25
Therefore, required domain is 0 ≤ x ≤ 25
Answer:
5400
Step-by-step explanation:
1.5×60=90 steps per min
90×60=5400 steps per hour
A
Explanation
She gets 11 for every hour but it doesn’t say how many hours so we put a variable ( in this case x ) so we have 11x and she revived $6 extra since it was received and not taken away we add 11x +6 and since it’s an equation we put 11x +6 = $39
For extra help x is equal to 3

Answer:
280 ft
Step-by-step explanation:
An auditorium is in the shape of an equilateral triangle with side length as 112 ft.
The stage extends from one vertex of the triangle to the mid-segment and the seating area extends from the mid-segment to the rear wall.
*The situation is represented in the attachment.
According to the midpoint theorem, the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side.
Hence, the length of the mid-segment in this case is,

Therefore, the perimeter of the seating area is,
