Given the function f(x)= 5(x+4) -6, solve for the inverse function when x=19.

f(x)= 5(x+4) -6

To find inverse we follow the steps given below

step 1: replace f(x) with y

y= 5(x+4) - 6

step 2: replace x with y and y with x

x= 5(y+4) -6

step 3: solve for y

x= 5(y+4) -6

x + 6 = 5(y+4)

x + 6 = 5y +20

x - 14 = 5y

step 4: replace y with f^-1(x)

We got the inverse function

solve for the inverse function when x=19.

we replace 19 for x in f^-1(x)

= 1

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
