How do you solve this question?

Lady bird [3.3K]

Answer:

$\large \boxed{\sf \ \ \ 2x-ln(1-x) \ \ \ }$

Step-by-step explanation:

Hello,

for any real x different from 1

$\dfrac{3-2x}{1-x}=\dfrac{2-2x+1}{1-x}\\\\=\dfrac{2(1-x)+1}{1-x}\\\\=2\dfrac{1-x}{1-x}+\dfrac{1}{1-x}\\\\=2+\dfrac{1}{1-x}$

if f(x)=2x

f'(x)=2

if g(x)=-ln(1-x)

$g'(x)=\dfrac{-1*-1}{1-x}=\dfrac{1}{1-x}$

So antiderivative of

$\dfrac{3-2x}{1-x}=2+\dfrac{1}{1-x}$

2x-ln(1-x)

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

What percent of 55 is 34? please help me answer this one it might also help somone else

Kitty [74]

To figure this out you can do a proportion
34 X
---- = ------
55 100
Then you would cross multiply to get
55x=3400
Next you would divide 3400/55 which would come out to be 61.8181818 which would be your percentage 61.81%

Question 6 of 9 (3•8) • 1 = 3 • (8.1) O A. True B. False

olga nikolaevna [1]

Answer:

No, (false). The question I assume was: $(3*8)*1=3*(8.1)$

Step-by-step explanation:

1. Multiple: 3 * 8 = 24

2. Multiple: The result of step No. 1: * 1 = 24 * 1 = 24

3. Conversion a decimal number to a fraction: 8.1 = $\frac{81}{10}$ = $\frac{81}{10}$

a) Write down the decimal 8.1 divided by 1: 8.1 = $\frac{81}{1}$

b) Multiply both top and bottom by 10 for every number after the

decimal point. (For example, if there are two numbers after the decimal

point, then use 100, if there are three then use 1000, etc.)

$\frac{8.1}{1}$ = $\frac{81}{10}$

Note: $\frac{81}{10}$ is called a decimal fraction.

c) Simplify and reduce the fraction

$\frac{81}{10} = \frac{81*1}{10*1} = \frac{81}{10}$

4. Multiple: 3 * 8.1 = $\frac{3*81}{1*10}$ = $\frac{243}{10}$

Multiply both numerators and denominators. Result fraction keep to lowest

possible denominator GCD(243, 10) = 1. In the next intermediate step the

fraction result cannot be further simplified by canceling.

In words - three multiplied by eighty-one tenths = two hundred forty-three

tenths.

5. Compare: The result of step No. 2 vs The result of step No. 4: = 24 vs $\frac{243}{10}$ = $\frac{24}{1}$ vs $\frac{243}{10}$ = $\frac{24*10}{1*10}$ vs $\frac{243}{10}$ = $\frac{240}{10}$ vs $\frac{243}{10}$ = 240 vs 243 = No
