Glenn Andrews recently bought a motorcycle for $3,950. If he had to pay 6% sales tax on the bike, what was the total cost of the
wolverine [178]
The answer is C) $4,187

First you need to turn the 6% into a decimal 6%--> .06

Now you need to multiply .06 to $3,850
$3,850x.06= $237 <---Sales Tax

Now just add thesales tax to the orignal price
$3,850+$237= $4,187

Find the inverse of the function.
Akimi4 [234]

Answer:

Step-by-step explanation:

The inverse is found by interchanging the x and y values and solve the result for y.

I will use y for f(x)

y = 4x^2

Inverse

x = 4y^2              Divide by 4

x/4 = 4y^2 /4    

x/4 = y^2             Take the square root of both sides.

sqrt(x/4) = sqrt(y^2)

y = sqrt(x/4)

g(x) = sqrt(x/4)  If you have a very fussy teacher, the inverse function could be written as

g(x) = +/- sqrt(x)/2

I expect that if the question is computer marked, I would try g(x) = sqrt(x)/2 first.
