Consider the function f(x)=-5x^2 +2x -8. find the critical point a of the function

To find the critical number of that function we have to find the derivative and set it equal to 0 and solve for x.  The derivative of the function is f'(x)=-10x+2.  If we set it equal to 0 and solve, we have x = -2/-10 which simplifies to x = 1/5.

I need some help please out
IceJOKER [234]

Question:

Solution:

Let the following equation:

\sqrt[]{12-x}=\text{ x}

this is equivalent to:

(\sqrt[]{12-x})^2=x^2

this is equivalent to:

12-x=x^2

this is equivalent to:

x^2+x-12=\text{ 0}

thus, we can conclude that

x= 3.

3/4 + (1/3 ÷ 1/6) - (-1/2) =?​
stepladder [879]

Answer:

[See Below]

Step-by-step explanation:

✦ Turn fractions into decimals:

  • \frac{3}{4} =0.75  
  • -\frac{1}{2} =-0.5
  • (We will do something different for \frac{1}{3} and \frac{1}{6}.)

✦ Divide:

  • \frac{1}{3} ÷ \frac{1}{6}=2
  • (Since the denominators are multiplies of each other we can divide them without having to change them into decimals.)

✦ Simplified Equation:

  • 0.75+2-(-0.5)

✦ Add:

  • 0.75+2=2.75

✦ Subtract:

  • 2.75-(-0.5)=3.25
  • (Subtraction rule is if there is 2 negatives next to each other in a problem it turns into a positive.)

✦ So your answer would be:

  • \frac{13}{4} (Exact Form)
  • 3~ \frac{1}{4} (Mixed Number Form)
  • 3.25 (Decimal Form)

How to factorise the difference of perfect squares. for the g on the top and j on the top
Fed [463]

Answer:

see explanation

Step-by-step explanation:

A difference of two squares is factored as

a² - b² = (a - b)(a + b)

(g)

1 - 81y²

= 1² - (9y)²

= (1 - 9y)(1 + 9y)

(j)

64x² - 25y²

= (8x)² - (5y)²

= (8x - 5y)(8x + 5y)
