With any equation you are allowed to take the logarithm of both sides so
5^c=125 now take the logarithm base 5 to both sides giving.
log5(5^c)=log5(125), using the rule log(a^b)=a*log(b) you get
c log5(5)=log5(125), since log5(5)=1
c=log5(125)
Your domain is all positive numbers, and your range is all numbers. this is because no matter what you plug in for y, x will only ever get extremely close to 0, but never reach it or go below it, and if you put in large values of y x will get very big.

Answer:
Okay so all you need to know is the percentage of the hydrogen peroxide.
We know that the total solution is 400 ml and the hydrogen peroxide solution is 8ml.
8/400
Percent means out of a hundred, this can go multiple ways.
<u>Way #1, benchmarking.</u>
So 8/400 simplified is 1/50 or 2/100.
1/50 is basically 2/100.
And percent means out of a hundred so 2/100 is basically 2percent.
<u>Way #2, proportions</u>
We want to know the percentage of hydrogen/ fabric dye
If you put it in numbers int he same fraction and put “x” as the unknown 8ml hydrogen peroxide solution you’d get.
8/400 = x/100
X/100 because percent means out of a hundred.
Now solve3
Cross multiply,
800 = 400x
divide 400 on both sides
2=x
Now plug it back in the proportion.
8/400 = 2/100
If you simplify to check if they are equal then it’s correct
Answer:
Final Profit = £11,000
Step-by-step explanation:
Incoming / Outgoing Profit / Cost Events £22,765
Staff £6,711
Security £3,452
Maintenance £500
Merchandise £967
Final Profit = £22,765 - £6,711 - £3,452 - £500 - £967 = £11,135
