Answer:
option-B
Step-by-step explanation:
we know that
Sum rule of logarithm:
which is same as
the log of a product (ab) is equal to the addition of log a nad log b
Subtraction rule of logarithm:
which is same as
the log of the quotient of a and b is equal to the log of a minus the log of b
Exponent rule of logarithm:
which is same as
the log of the quantity a raised to b is equal to the product of b and the log of a
so,
option-B is not correct
Answer:
Jogging 6th time.
Step-by-step explanation:
We have been given that Vicki started jogging the first time she ran she ran 3/16 mile the second time she ran 3/8 mile and the third time she ran 9/16 mile.
We can see that the distance Vicki covers each time forms a arithmetic sequence, where 1st term is 3/16.
We know that an arithmetic sequence is in form , where,
= nth term of sequence,
= 1st term of sequence,
n = Number of terms in sequence,
d = Common difference.
Let us find common difference of our given sequence as:
Since Vicki needs to cover more than 1 mile, so we nth term of sequence should be greater than 1.
Let us solve for n.
We can also write next terms of our sequence as:
Therefore, Vicki will run more than 1 mile when she is jogging for 6th time.
