We have that
<span>Log3 a/3
</span>Rewrite log3(a/3) using the change of base <span>formula
we know that
</span>The change of base rule can be used if a and b are greater than 0 and not equal to 1, and x is greater than 0<span>.
</span>so
loga(x)=<span>logb(x)/<span>logb<span>(a)
</span></span></span>Substitute in values for the variables in the change of base <span>formula
</span>
in this problem
b=10
a=3
x=a/3
log3(a/3)=[log (a/3)]/[log (3)]
the answer is
[log (a/3)]/[log (3)]
Pi is an irrational number,
Answer:
- Jim = 6 hours
- Regina = 12 hours
- Together at same rate = 3 hours
Step-by-step explanation:
- Let Jim's speed is J and Regina's speed is R and the work is W
<u>We have:</u>
<u>Substitute J with 2R:</u>
Regina needs 12 hours to complete work
and
<u>Substitute R with J/2:</u>
Jim needs 6 hours to complete same work
<u>If Regina works as quickly as Jim:</u>
Then
<u>Jim can complete 1/6 of work in one hour, they both can complete twice work:</u>
<u>Time to complete work:</u>
Answer:
combine the two var. and you get 5y=11 so its 5.5 =y
