Answer:
Step-by-step explanation:
The extrema will be at the ends of the interval or at a critical point within the interval.
The derivative of the function is ...
f'(x) = 3x² -4x -4 = (x -2)(3x +2)
It is zero at x=-2/3 and at x=2. Only the latter critical point is in the interval. Since the leading coefficient of this cubic is positive, the right-most critical point is a local minimum. The coordinates of interest in this interval are ...
f(0) = 2
f(2) = ((2 -2)(2) -4)(2) +2 = -8 +2 = -6
f(3) = ((3 -2)(3) -4)(3) +2 = -3 +2 = -1
The absolute maximum on the interval is f(0) = 2.
The absolute minimum on the interval is f(2) = -6.
Answer:
C: 23 cm
Step-by-step explanation:
This is the answer because:
1) Area of trapezoid is: (base1 + base2)/2 x height
2) In this case, it is 14 + 8 which is 22. 22/2 is 11.
3) Now we have to do 253/11 which is 23 cm.
Hope this helps! :D

Answer:
Step-by-step explanation:
GIVEN: In the 
school year in country A, there were 
foreign students from country B. This number is 
more than the number of students from country C.
TO FIND: How many foreign students were from country C.
SOLUTION:
Total foreign students from country B 
let the foreign students from country C be 
As the students from country B is more than the country C
Students from country B
Hence the number of students from country C are 
Answer:
x=19
Step-by-step explanation:
(7x+7) + (2x+2) = 180
9x + 9 = 180
9x=171
x=19
