The inverse function of the logarithm is the exponential function:
In fact, the expression means that if you want to obtain x, you have to give y as exponent to e:
So, we can check both expressions:
, because this expression means "I am giving to e the following exponent: a number that, when given as exponent to e, gives x".
On the other hand, you have
, because this expression means "what exponent do I have to give to e to obtain e^x?". Well, you've basically already written it: if you want to obtain e^x, you have to give the exponent x.
So, we've shown that , which proves that and are one the inverse function of the other.
Answer: $9400
Step-by-step explanation:
.06x = $564
divide both sides by .06
x = $9400
Step-by-step explanation:
m<C = 90°
According to the laws of cosine,
c²= a²+b²-2ab. cos(C)
c²=a²+b²-2ab.cos(90°)
c²=a²+b²-2ab.0 { cos(90°)= 0}
c²=a²+b²
a²=c²-b²
