Factorise completely:<br> (a) 8m - 50 n2
Sever21 [200]

Answer:

2(4m-25n2)

Step-by-step explanation:

To factorise,we will have to know the value that can divide both variables given

But based on this question,we have different variables that is m and n

So we don't have to deal with that but with the numbers which means that we will only deal with the numbers ignoring the letters

8m-50n2

So the only number that can divide the two is 2

2(4m-25n2)

This cannot be solved further so the final answer is 2(4m-25n2)

I hope this will help you

Identify the minimum value of the function y = 2x^2 + 4x
statuscvo [17]

The function's minimum value is -2 at x = 1

Step-by-step explanation:

Given function is:

y = 2x^2+4x

In order to find the maxima or minima of a function, first of all, we have to find the derivative of the function

So,

Taking derivatives on both sides

\frac{d}{dx}(y) = \frac{d}{dx} (2x^2-4x)\\\frac{dy}{dx} = \frac{d}{dx} (2x^2) - \frac{d}{dx} (4x)\\y' = 2 \frac{d}{dx} (x^2) - 4 \frac{d}{dx}(x)\\y' = 2 (2x) \frac{d}{dx}(x) - 4(1)\\y' = 4x (1) - 4\\y' = 4x - 4

We have to find the roots of first derivative

So,

4x-4 = 0\\4x = 4\\x = \frac{4}{4} \\x = 1

Taking second derivative

\frac{d}{dx} (y') = \frac{d}{dx} (4x-4)\\y'' = 4

We can see that the second derivative of the function is a constant so the function has a minima at x=1

For minimum value, putting x = 1 in the function

= 2(1)^2 - 4(1)\\= 2(1) - 4\\= 2-4\\= -2

The function's minimum value is -2 at x=1

Is 0.4 less than greater than,or equal than to 44 percent
Llana [10]
To find this what you do is you take the percent and make it into a decimal by moving the decimal two spaces to the left so from 44% to 0.44 so in the end 0.4 is less then 44% because 44% is 0.44
