The answer is

3/14, 2/7, 1/2

1st you would need to find a common denominator which would be 14.
3/14 =3/14
1/2 = 7/14
2/7 = 4/14
Then you can compare them easier and see that the order is 3/14, 2/7, 1/2

What is the inverse of the function?
f(x) = 3^x + 1

f^-1(x)= log3 (x) +1
f^-1(x)= log3(x)-1

f^-1(x)=log3(x+1)

f^-1(x)=log3(x-1)

Answers

Answer:

f^-1(x)=logs3(x+1)

Step-by-step explanation:

Let y=f(x)

[tex]\\ \rm\Rrightarrow y=3^x+1[/tex]

Interchange

[tex]\\ \rm\Rrightarrow x=3^y+1[/tex]

[tex]\\ \rm\Rrightarrow lnx=ln(3^y+1)[/tex]

[tex]\\ \rm\Rrightarrow x=\dfrac{ln(y-1)}{ln3}[/tex]

Again interchange

[tex]\\ \rm\Rrightarrow f^{-1}(x)=\dfrac{ln(x-1)}{ln3}[/tex]

what this value means in the context of this situation

The zero of the function is at ___. This represents that after tying ribbon on ____ gift bags, Juanita will have ____ feet of ribbon left.

Answers

The zero of the function is at 32 gift bags. This represents that after tying ribbon on 32 gift bags, Juanita will have zero feet of ribbon left.

According to the question;

The function r = 24 -0.75g represents the amount of ribbon r Juanita has left after tying ribbon on g gift bags.

The zero of the function is at, r = 0.

Therefore;

0 = 24 -0.75g

g = 24/0.75

g = 32.

This value means that after tying 32 gift bags, Juanita will have zero feet of ribbon left.

ACME insurance company estimates that the probability of the owners’ of a house worth between $120,000 to $170,000 making a claim for $5000 is 0.08, and that the probability of the house and contents being totally destroyed is 0.0041. Should that tragedy happen, the company will have to pay $150,000. The company charges $1300 for the insurance policy.

What is the expected value of this policy to the insurance company?

Round your answer to two decimal places.

Answers

The expected value of this policy to the insurance company is $285.00.

Using this formula

Policy expected value=Insurance policy charges-[(Probability × Claim)+(Probability × Claim)]

Let plug in the formula

Policy expected value=$1,300-{(.0041)($150,000)+(.08)($5,000)]

Policy expected value=$1,300-($615+$$400)

Policy expected value=$1,300-$1,015

Policy expected value=$285.00

Inconclusion the expected value of this policy to the insurance company is $285.00

What is the relationship for angle 1 and angle 8

Answers

Answer:

Step-by-step explanation:

In this cofiguration, there are 8 angles. 4 equal one value and 4 are their supplements of the first 4.

6 and 80 and 2 and 3 are all equal to 80 degrees.

1 4 5 and 8 are the supplements. So whatever their value, they are all equal to the same thing. <1 = <8

They are supplementary to the 80 degree angle

<1 + 80 = 180 Subtract 80 from both sides

<1 = 180 - 80

<1 = 100

So angle 1 and <8 both equal 100 degrees.

Answer:

Alternate exterior angles.

Step-by-step explanation:

Alternate exterior angles are angles on opposing sides of the transversal and the outside of the parallel lines. Moreover, they are congruent. Therefore, ∠1 ≅ ∠8.

You deposit $9000 in an account that pays 5% interest compounded quarterly.

A. Find the value of one year

B.Use the future value formula for simple interest to determine the effective annual yield
(Formula: A=P(1 +rt)

Answers

Step-by-step explanation:

Given:

Deposit P = $9000Interest rate r = 5% = 0.05Time t = 1 yearNumber of compounds n = 4

A. Find the value of one year

[tex]A = P(1 + r/n)^{nt} = 9000(1+0.05/4)^4=9458.51[/tex]

B. Use the future value formula for simple interest to determine the effective annual yield

[tex]A=P(1+rt)\\[/tex][tex]r=(A/P-1)/t[/tex][tex]r=(9458.51/9000-1)/1=0.0509[/tex] r = 5.1%

Answer:

A) $9458.51

B) 5.09% (2 d.p.)

Step-by-step explanation:

Part A

Compound Interest Formula

[tex]\large \text{$ \sf A=P\left(1+\frac{r}{n}\right)^{nt} $}[/tex]

where:

A = final amountP = principal amountr = interest rate (in decimal form)n = number of times interest applied per time periodt = number of time periods elapsed

Given:

P = $9000r = 5% = 0.05n = 4 (quarterly)t = 1 year

Substitute the given values into the formula and solve for A:

[tex]\implies \sf A=9000\left(1+\frac{0.05}{4}\right)^{4 \times 1}[/tex]

[tex]\implies \sf A=9000(1.0125)^4[/tex]

[tex]\implies \sf A=9458.508032...[/tex]

Therefore, the value of the account after 1 year is $9458.51.

Part B

Simple Interest Formula

A = P(1 + rt)

where:

A = final amountP = principalr = interest rate (in decimal form)t = time (in years)

Given:

A = $9458.51P = $9000t = 1 year

Substitute the given values into the formula and solve for r:

[tex]\implies \sf 9458.51=9000(1+r(1))[/tex]

[tex]\implies \sf 9458.51=9000(1+r)[/tex]

[tex]\implies \sf \dfrac{9458.51}{9000}=1+r[/tex]

[tex]\implies \sf r=\dfrac{9458.51}{9000}-1[/tex]

[tex]\implies \sf r=0.050945...[/tex]

[tex]\implies \sf r=5.0945... \%[/tex]

Therefore, the effective annual yield is 5.09% (2 d.p.).

IF Tyler s currently 5 inches
tal, how many inches more
does he need to grow to be
feet tal?

Answers

Hey there! Your answer is:

7 inches

Explanation:

If Tyler is 5 inches tall, he needs to grow 7 inches to be a foot tall. This is because 12 inches are in 1 foot. We can do a simple subtraction problem to figure this out.

12 inches - 5 inches = 7 inches

Since Tyler is 5 inches tall, we know that if we subtract 12 inches from 5 inches we will get the number of inches he needs to grow.

Answers

Adjoa take-home pay earned for the past month is Ghc4,265.46

From the question,

We are to determine the amount of take-home pay Adjoa earn the past month

From the given information, we have that

Adjoa’s gross salary for last month was Ghc4,687.24

Also

Ghc421.78 was deducted from Adjoa’s salary pay

To determine how much take-home pay Adjoa earn the past month,

We will subtract the amount deducted from Adjoa’s salary pay from Adjoa’s gross salary for last month

That is,

Adjoa take-home pay = Ghc4,687.24 - Ghc421.78

Adjoa take-home pay = Ghc4,265.46

Hence, Adjoa take-home pay earned for the past month is Ghc4,265.46
