Answer:
the vertex is ( 3 , 3)
Symetric axis‘s equation: x = 3
Step-by-step explanation:
Let‘s name the function ” f ”
f(x) = y = 2x² - 12x + 21
the vertex has coordinates of ( -b/2a , f(-b/2a) )
-b/2a = 12/2(2) = 12/4 = 3
f(-b/2a) = f(3) = 2(3)² - 12(3) + 21 = 3
then the vertex is ( 3 , 3)
the symetric axis has the equation :
x = -b/2a
then
It's not clear to me what the given interval is supposed to be, so I'll use a generic one, [a, b] with a < b.
The average acceleration of the particle over this interval is given by the average rate of change of v(t),

Answer:
76
or 238.76 
Step-by-step explanation:
The volume of a cylinder is V = 
Here the radius is r =
= 
The height is given as 19 ft
Then plug in all the numbers into the equation
V = 
Answer: 9/20 for rent = $558
1/2 for food implies= $620
Step-by-step explanation:
9/20 ×$1240= $558
While
1/2 ×$1240= $620
Ans: The average rate of change of function =

(in fraction)
Explanation:The average rate of change of function =

Where
b = 8 (x's upper bound)
a = 0 (x's lower bound)

Hence the average rate of change of function =

(in fraction)
