11. calculate the following logarithms.
a. log5(25)

the logarithmic solution of log₅(25) is equal to 2

Step-by-step explanation:

given,

       log₅(25)

now using logarithmic identity

log ₓ (x) = 1  and

log (aˣ)  = x log (a)

now,

       log₅(25)

       =log₅(5²)

       =2 log₅(5)

       =2

hence, the logarithmic solution of log₅(25) is equal to 2

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8

step-by-step explanation:

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
