OK, I can do that. But you'll have to tell me what the function rule is.
Every function is a different rule.
You can take the log of the left and right hand side, and then apply the <span>logarithm rules:
log(a</span>ˣ) = x·log(a)
log(ab) = log(a) + log(b)
log(9^(x-1) * 2^(2x+2)) = log(6^(3x))
log(9^(x-1)) + log(2^(2x+2)) = 3x log(6)
(x-1) log(9) + (2x+2) log(2) - 3x log(6) = 0
x(log9 + 2log2 - 3log6) = log9 - 2log2
x = (log9 - 2log2) / (log9 + 2log2 - 3log6)
simplifying by writing log9 = 2log3 and log6 = log2+log3
x= 2(log3 - log2) / (2log3 + 2log2 - 3log2 - 3log3) =
x= -2(log3 - log2) / (log3 + log2) = -2 log(3/2) / log(6)
So 6^x = 4/9
Answer:
Angle 1 = 128
Angle 2 = 52
Angle 3 = 47
Angle 4 = 133
Angle 5 = 81
Step-by-step explanation:
Angle 5 is 81
Angle 3 is 47
Angle 4 is 133
Angle 2 is 52
Angle 1 is 128
If you would like to know the purchase price of Wilma's game, you can calculate this using the following steps:
15% of $43.89 = 15% * 43.89 = 15/100 * 43.89 = $6.5835 = $6.58
$43.89 - $6.58 = $37.31
5% of $37.31 = 5% * 37.31 = 5/100 * 37.31 = $1.8655 = $1.87
$37.31 - $1.87 = $35.44
The correct result would be <span>$35.44.</span>
