If the diameter of the cylinder's base is 10, then the radius is half that, or 5.
0.4 and 0.40 are equal. That zero on the hundredths place does not matter.
Answer:
between 7 and 8
Step-by-step explanation:
Consider perfect squares either side of 60, that is
49 < 60 < 64, then
< 
< 
, that is
7 < < 8
Answer: x = 1500/ n
Step-by-step explanation:
X- price per student
N- number of students
Y= (x-2)² + 5. We can write it as : y-5 = (x-2)². The general equation of a quadratic function is :
(y-k) = a(x-h)², where h and k are the vertex of the parabola and a, the coefficient which determines whether the parabola opens upward or downward.
So, y-5 = (x-2)²
Having said that we can say that the VERTEX( 2,5) and since a=1 (a>0) the parabola is open upward OR it passes by a MINIMUM (Then the vertex is minimum)
The domain (x- value) is all Real { x|x = -∞ to x=+∞}
The Range (y-value) is all y ≥ 5
