Find the domain of f and f −1 and its domain. f(x) = ln(ex − 3). (a) Find the domain of f. (Enter your answer using interval notation.) (−2,[infinity]) (b) Find f −1. f −1(x) = x+ln(3)

Answers

Answer:

a.Domain of f=(1.099,\infty)

b.f^(-1)(x)=ln(e^x+3)

Step-by-step explanation:

Let y=f(x)=ln(e^x-3)

We know that domain of ln x is greater than zero

e^x-3>0

Adding 3 on both sides of inequality

e^x-3+3>0+3

e^x>3

Taking on both sides of inequality

lne^x>ln 3

x>ln 3=1.099

By using lne^x=x

Domain of f=(1.099,\infty)

Let y=f^(-1)(x)=ln(e^x-3)

e^y=e^x-3

By using property lnx=y\implies x=e^y

e^x=e^y+3

Taking ln on both sides of equality '

lne^x=ln(e^y+3)

x=ln(e^y+3)

Replace x by y and y by x

y=ln(e^x+3)

Substitute y=f^(-1)(x)

f^(-1)(x)=ln(e^x+3)

Solve the equation: b/5 + 15 =45
is answer 150

Answers

Answer: The answer is 150.

Step-by-step explanation:

First of all, we need to use inverse operations to solve this arithmetical equation.

First, multiply both sides by 5.

5(B/5 + 15) = 5(45).

B + 75 = 225.

Now we need to use the inverse operation of addition to get B by itself.

The inverse operation of addition is subtraction. And so we must subtract each side by 75.

B + 75 - 75 = 225 - 75.

B = 150.

So it looks like you are correct. 150 is the answer.

Write the complex number in the form a + bi. 8(cos 30° + i sin 30°)

Answers

Answer:

4√(3) +4i

Step-by-step explanation:

Use the Euler's Formula, which is given by:

r e^(i \theta) = r(cos(\theta)+i sin(\theta))

Where:

a=rcos(\theta)\nb=rsin(\theta)\n\ntan(\theta)=(b)/(a)

From the problem, you can see:

r=8\n\theta=30^(\circ)

So:

a=8*cos(30)=4 √(3) \approx6.928\nb=8*sin(30)=4

Therefore, the complex number in its rectangular form is:

4√(3) +4i

Answer:

4√(3)+4i

Step-by-step explanation:

8(\cos 30^\circ + i \sin 30^\circ) = 8 (√(3))/(2)+i8(1)/(2)=4√(3)+4i

What is nearest tenth of 0.273

Answers

Answer:

0.3

To round 0.273 to the nearest tenth consider the hundredths’ value of 0.273, which is 7 and equal or more than 5. Therefore, the tenths value of 0.273 increases by 1 to 3.

0.273 rounded to the nearest tenth = 0.3
