Absolute maximum value for this expression is  ( \frac{1}{2} ,   \frac{5}{4}  ).

What is absolute maximum ?

  • The largest value that a mathematical function can have over its entire curve (see curve entry 3 sense 5a) .
  • The absolute maximum on the graph occurs at x = d, and the absolute minimum of the graph occurs at x = a.— W.

f(x) = 2x³ - 4x² +2  ,              [ 1/2 , 1 ]

First critical points , by setting f'(x) = 0

   f'(x) = d/dx ( 2x³ - 4x² + 2 )

          = 6x² - 8x

Now 6x² - 8x = 0

        2x( 3x - 4 ) = 0

          2x = 0    or 3x-4 = 0

             x = 0  ,     x = 4/3

Critical points x = 0 , x = 4/3

The critical points are not in the given interval  [1/2, 1 ]

evaluate the function at the end points .

x = 1/2  ⇒    f(1/2) = 2(1/2)³ - 4( 1/2)² + 2

                            = 1/4 - 1 + 2

                            = 1/4 + 1

                            = 5 /4

x = 1 ⇒             f(1) = 2 (1)³ - 4(1)² +2

                             = 2 - 4 + 2  ⇒ 0

∴ absolute maximum = ( \frac{1}{2} ,   \frac{5}{4}  )

KATRIN_1 [288]

Answer:

Step-by-step explanation:

Given

Jar contains 4 white and 4 black marbles

We randomly select 4 marbles out of which 2 are white and 2 are black

Probability that 2 white and 2 black marbles are selected is

P=\frac{^4C_2\times ^4C_2}{^8C_4}

P=\frac{18}{35}

The process is continue for n trails until we choose the correct order

i.e. we have to fail in n-1 trails

For exact n selection Probability is given by

Req.\ Probability=Probability\ of\ failure\ in\ (n-1)\ trials\times Probability\ of\ getting\ exact\ order

=\left ( 1-\frac{18}{35}\right )^{n-1}\times \frac{18}{35}

lisabon 2012 [21]

Answer:

a   10 yd   2ft  7 in

b 10 yd  1 ft  2 in

c  99 yd

d.  4840 sq  yd  7 sq ft  119 sq in  

Step-by-step explanation:

a.      2 ft. 5 in. +

9 yd. 3 ft. 2 in.

---------------------

9 yd   5ft   7 in

but 3 ft = 1yd

9 yd   5ft   7 in

+1yd   - 3ft

---------------------------

10 yd   2ft  7 in



b. 4 yd. 8 in

+ 6 yd. 6 in.

----------------------

10 yd   14 in

but 12 in = 1ft


10 yd       14 in

     + 1ft   - 12 in

---------------------

10 yd  1 ft  2 in



c. 29 yd. 2 ft. 11 in.

  55 yd. 1 ft. 10 in.

+ 13 yd. 1 ft. 3 in.  

--------------------------

97 yd   4 ft   24 in

12 in = 1ft

24 in = 2ft


97 yd   4 ft   24 in

           +2ft    - 24 in

--------------------------------

97 yd   6ft

3 ft = 1yd

6f = 2yd


97 yd   6ft

+2yd   - 6ft

---------------------

99 yd


d. 4,839 sq. yd. 8 sq. ft. 139 sq. in.

                      + 7 sq. ft. 124 sq. in.

--------------------------------------------------

  4839  sq yd  15 sq ft   263 sq in

12*12 = 144 sq in = 1 sq ft

 4839  sq yd  15 sq ft   263 sq in

                       + 1 sq ft  - 144 sq in

--------------------------------------------------

4839  sq yd  16 sq ft  119 sq in

3ft * 3 ft = 9 sq ft = 1 sq yd

4839  sq yd  16 sq ft  119 sq in

      +1 sq yd  - 9 sq ft

----------------------------------------------

4840 sq  yd  7 sq ft  119 sq in
