Answer:
The answer is 384.85 yd to the power of 3
Step-by-step explanation:
πr2h
= π×3.52×10
= 122.5π
= 384.85
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:
C= 5, -5
Step-by-step explanation:
Answer:
The answer is C.
Step-by-step explanation:
It cannot be between 3 and 4 because 2/3 is less than 1. You cannot end up with a larger number than 3 in this case. Similarly, it cannot be less than 2/3 because you are multiplying it by 3, which is larger than your first number.
Therefore, it has to be between 3 and 2/3 because you are taking two thirds of 3, which is 2.
