3 log₃ 4a=3

1)a(log_b c)=log_b c^a
log₃(4a)³=3

2) log_a x=n  ⇔  a^n=x
log₃ (4a)³=3 ⇔  3³=(4a)³
27=64a³
a³=27/64
a=∛(27/64)
a=3/4

Answer: a=3/4

Answer for brainlest and 25 points
nordsb [41]

Answer:

Order from greatest to least: 10.5, 3\pi +1, \sqrt{105}

Step-by-step explanation:

step 1 simplify each number

3π + 1  = 10.4247779

*round to the nearest tenth*

3π + 1 = 10.4

\sqrt{105} =10.2469507

*round to the nearest tenth*

\sqrt{105} =10.2

10.5 = 10.5

Now that we have simplified each number we can easily put them in order from greatest to least

10.5 is the greatest number

10.4 is the middle number

10.2 is the lowest number

so 10.5, 10.4, 10.2

Now we put them back in the original form

10.5 = 10.5

10.4 = 3π + 1

10.2 = \sqrt{105}

Your answer is

10.5 , 3\pi + 1, \sqrt{105}

V=Bh

96.37=7.5

7.5B/7.5=B

B stands for base or big b

so you do the same thing to the volume

Is y=9x+1 a function
Lostsunrise [7]

Answer:

Yes

Step-by-step explanation:

Yes , y=9x+1 is a function

There are two conditions for a relation to be a function.

Condition 1 :

For every value of x there must be a value existing

In this case if we take any real value of x , there will be some y defined for that value hence this condition satisfies.

Condition 2 :

No value of x should have two different values in  y

In this case also , there are for every real value of x , we have an uniques value of y. Hence this condition also satisfies here.

Hence y=9x+1 is a function
