Start by converting 6% to a decimal by dividing by 100, = 0.06
Multiply that by the cost of the PlayStation five, and that is how much tax you pay.
499.99 x 0.06 = 29.9994
The question says to round it to the nearest hundredths, so it’s $30
Given the function f (x) = 3x, find the value of f-1 (81).
For this case, the first thing you should do is rewrite the function.
We have then:
y = 3 ^ x
From here, we clear the value of x:
log3 (y) = log3 (3 ^ x)
log3 (y) = x
Then, we rewrite the function again:
f (x) ^ - 1 = log3 (x)
Now, we evaluate the inverse function for x = 81:
f (81) ^ - 1 = log3 (81)
f (x) ^ - 1 = 4
Answer:
the value of f-1 (81) is:
f (x) ^ - 1 = 4
Y-99=-1/33(x-22)
a). y = 1/33x + 98 1/3
b) 33y = x + 109 1/3
x - 33y = -109 1/3
You have to get from $30 to $21.75
21.75/30=0.725 x 100= 72.5% of the original price
