Percent formula : is/of = %/100

what is 5% of 400
is = x
of = 400
% = 5

now we sub
x/400 = 5/100
this is a proportion, so we cross multiply
(100)(x) = (400)(5)
100x = 2000
x = 2000/100
x = 20......so 5% of 400 is 20

) For which values of x is f '(x) zero? (Enter your answers as a comma-separated list.) x = (No Response) For which values of x
grigory [225]

Answer:

Check below, please

Step-by-step explanation:

Step-by-step explanation:

1.For which values of x is f '(x) zero? (Enter your answers as a comma-separated list.)

When the derivative of a function is equal to zero, then it occurs when we have either a local minimum or a local maximum point. So for our x-coordinates we can say

 f'(x)=0\: at \:x=2, and\: x=-2

2. For which values of x is f '(x) positive?

Whenever we have  

 f'(x)>0

then function is increasing. Since if we could start tracing tangent lines over that graph, those tangent lines would point up.

 f'(x)>0 \:at [-4,-2) \:and\:(2, \infty)

3. For which values of x is f '(x) negative?  

On the other hand, every time the function is decreasing its derivative would be negative. The opposite case of the previous explanation. So

 f'(x)

4.What do these values mean?

 f(x) \:is \:increasing\:when\:f'(x) >0\\\\f(x)\:is\:decreasing\:when f'(x)

5.(b) For which values of x is f ''(x) zero?

In its inflection points, i.e. when the concavity of the curve changes. Since the function was not provided. There's no way to be precise, but roughly

at x=-4 and x=4

Seven less than the product of a number n and 1/6 is no more than 94
antiseptic1488 [7]

Answer:

  • n ≤ 606

Step-by-step explanation:

<u>Seven less than the product of a number n and 1/6 is no more than 94, translating:</u>

  • n*1/6 - 7 ≤ 94

<u>Solving for n:</u>

  • n/6  ≤ 94 + 7
  • n/6 ≤ 101
  • n ≤ 101*6
  • n ≤ 606

If you know that 7 - square root 5 is it root of a polynomial function
Kitty [74]

Answer:

As you must know, If one root of the polynomial 7-√5, the other will be 7+√5 i.e irrational root occur in pairs.

A polynomial function cannot have single unreal i.e irrational root. It always occur in pairs.

So , consider a polynomial function of any degree, if it has a root 7-√5, then it must have another root as 7+√5.

A polynomial can't have 7-√5 as a single root.
