To find the inverse, switch the variables and solve for f(x).

x = e^f(x) + 6
x - 6 = e^f(x)
f(x) = ln(x-6)

hope this helps :)

The inverse means reflect across the x=y line
basically switch x and y and solve for y

steps
replace f(x) with y
switch x and y
solve for y
replace y with f⁻¹(x)

so

f(x)=e^x+6
y=e^x+6
x=e^y+6
minus 6 both sides
x-6=e^y
take the ln of both sides
ln(x-6)=y
y=ln(x-6)
f⁻¹(x)=ln(x-6)

ohaa [14]

According to picture Jennifer’s grandmother buys = 28 kg of carrots.

Total number of grandchildren = 3.

Number of kilograms of carrots are distributed equally.

<u>In order to find the Number of kilograms of carrots are distributed, we need to divide total Kgs of carrots by total number of grandchildrens.</u>

Therefore ,

28 ÷ 3 .

On dividing 28 by 3, we get 7.

Therefore, Jennifer will get 7 kilograms of carrots.

PLZZZZZ NEED HELP!!!!!!
tia_tia [17]

Answer:

Total annual premium = $1770.10

Step-by-step explanation:

Given the information in the problem, looking at the different categories of each level of insurance and the corresponding premium will give you the amounts for each part.  To find the total annual premium, you need to find the sum of all the parts and then multiply this by the rating factor for his gender and age group.  

Since he is purchasing 100/300/100 liability insurance, you need to first look at the 'Liability Insurance' table and locate the 100/300 option under 'Bodily Injury'.  This premium is $450.  Also, he is purchasing an additional 100 for Property damage which is an added premium of $375.

Next, he is getting collision insurance with a $100 deductible.  This is the second column in the second table and has a premium of $215.  He also wants comprehensive insurance with a $250 deductible which has a premium of $102.  

Since he is a 26-year-old male, his rating is 1.55, so we will need to multiply the sum of his premiums by this number:

(450 + 375 + 215 + 102)1.55 = $1770.10
