Answer:
xy ≈ 2.3
Step-by-step explanation:
Logarithms can be used to find x and y.
3^x = 4
x·log(3) = log(4)
x = log(4)/log(3)
__
4^y = 12
y = log(12)/log(4)
__
Then xy is ...
xy = log(4)/log(3) × log(12)/log(4) = log(12)/log(3)
xy ≈ 1.079/0.477
xy ≈ 2.26
M=153.46w, L=128.90+127.68w they will be equal when M=L so
153.46w=128.90+127.68w subtract 127.68 from both sides...
25.78w=128.90 divide both sides by 25.78
w=5
So after five weeks they have deposited the same amount of money.
Each of them has deposited <span>$153.46*5=$767.30, so the account has twice that amount.
Thus the total amount in the account is 767.30*2=$1534.60</span>
