To evaluate this expression properly, we must follow order of operations (PEMDAS) rules.  Here, that means doing exponentiation first, followed by mult. and div., followed by addition and subtraction.  

2−4÷2+2^3 becomes 2−4÷2+8 after exponentiation.

2−4÷2+8 becomes 2-2+8 after division.

2-2+8 = 8

Your final value for this expression is 8.

1. The first one I think you would divide 8 from 64 n get 8 so thats 8%. Answer to that would be the Store.

2. You would!! 56%

3. Multiply 2.5 to 40 and 25. You need a denominator of 100. 62.5/100
So yes you did find at least 60%


I think I did this right. Hope it helps!

Find the absolute minimum and absolute maximum values of f on the given interval. f(x) = (x2 − 1)3, [−1, 2]
Alja [10]

Given :

F(x)=3(x^2-1)

To Find :

the absolute minimum and absolute maximum values of f on the given interval

[-1,2] .

Solution :

Now , getting first order differential equation and equating its equal to zero.

\dfrac{d(3x^2-3)}{dx}=0\\\\6x=0\\x=0

So , x=0 is critical point .

Now , coefficient of x^2 is positive .

Therefore , it is increasing function after  x=0 .

So , min value will be at , x=0.

Min = (0^2-1)\times 3=-3

And maximum value will be the maximum at the x=2 because it is increasing function .

Max=(2^2-1)\times 3=9

Therefore , max and min value is 9 and -3 respectively .

Hence , this is the required solution .
