Answer:

90%

Step-by-step explanation:

An easy way that I use to use to get percentages was get the denominator to equal 100. Anything over 100 would be the percentage, that's the way I was taught.

You multiply by $\frac{5}{5}$ to get the denominator, 20, to equal 100

$\frac{18}{20}$ × $\frac{5}{5}$ = $\frac{90}{100}$

$\frac{90}{100}$ = 90%

PLEASE HELP Which expression represents the difference quotient of the function f (x) = negative StartRoot 2 x EndRoot?

natali 33 [55]

Answer:

c is the correct option

Step-by-step explanation:

from,

f'(x) = h >0 f(x + h) - f(x)

f(x) = - √2x

f(x + h) = - √(2x + h)

f'(x) = h>0 -√(2x + h) - √2x

rationalize the denominator

= h>0 -√(2x + h) + √2x (-√(2x + h) - √2x)

h (-√(2x + h) - √2x)

= h>0 4x + 2h - 4x

h(-√(2x + h) -√2x)

= h>0 2h

h(-√(2x+h) - √2x)

= h>0  2 

-√(2x+h) - √2x

Learning Task 3: In your answer sheet, write the letter of the correct answe

miss Akunina [59]

Answer:

a.) May or may not a polynomial function ( depends on c)

b.) Not a polynomial function.

c.) Not a polynomial function.

d.) It is a polynomial function.

Step-by-step explanation:

A polynomial function is of the form - $a_{n}x^{n} + a_{n-1} x^{n-1} + a_{n-2} x^{n-2} + .....+ a_{1}x + a_{0}$

where n is positive integer and n $\neq$ 0

a.)

P(x) = 2x³ + 32 - 4x + 4c

It may or may not a polynomial function because we did not know about the constant c.

b.)

H(x) = 4 $x^{\frac{1}{2} }$ - 3x⁴

It is not a polynomial function because $\frac{1}{2}$ is not integer.

c.)

G(x) = 2 $x^{-3}$ + 5

It is not a polynomial function because -5 is not a positive integer.

d.)

F(x) = 2x³ - 5x + 33x²

It is a polynomial function.
