I believe the value of log3 729 is 6

Vinil7 [7]3 years ago

3 0

Answer:

Step-by-step explanation:

Rewrite - log 3 ( 729 ) = x in exponential form using the definition of a logarithm. If x and b are positive and real numbers and b does not equal 1, then log b ( x ) = y is equivalent to b^{y} = x .

3 x = 729

Create equivalent expressions in the equation that all have equal bases.

3^{x} = {3^6}

Since the bases are the same, the two expressions are only equal if the exponents are also equal.

x = 6

The variable x is equal to 6

Ksenya-84 [330]

Answer:

The first histogram is the answer.

Step-by-step explanation:

Like any other questions, you can use the process of elimination to answer this question.

There are only one fruit that has a water content of 60 - 64 %

Right away you can eliminate the second answer choice.

There are two fruits that has a water content of 65 - 69 %

All the other three has the same thing

There are only two fruits that has a water content of 70 to 74 %

Right away answer choice three can be eliminated

There are 4 fruits that are 75 - 79 % full with water

Both has same thing

There are 9 friuts that are 80 - 84 % full with water

THERE ARE 2 FRUITS THAT CONTAIN 85 - 89 % water

THE ANSWER IS THE FIRST HISTOGRAM.

PLEASE HELP ME QUICKLY!!! Given that N:{1,2,3,5,8,13} and M:{−9,−8,−6,−4,−2,4}, which statements about N and M are true?

Lelechka [254]

Answer:

The intersection of N and M contains only those elements that are in both N and M.

The intersection of N and M is ϕ.

N∩M=∅

Step-by-step explanation:

Given

M = { 1, 2, 3, 5, 8, 13}

N = {-9, -8, -6, -4, -2, 4}

Now let us see each statement one by one.

The intersection of N and M contains only those elements that are in both N and M.

The statement is true because by definition intersection of two sets consists of common elements of both sets.

The intersection of N and M is ϕ.

The statement is true. As there is no common element in both sets.

The intersection of N and M is {−9,−8,−6,−4,−2}.

The statement is false because there is not common element in M and N.

N∪M=∅

The statement is false as the union consists of elements of both sets so it can't be empty.

N∩M=∅

True. Because no common element so intersection will be an empty set..

Thomas is 4 years older than his brother william. in five years the sum of their age will be 24. how old is each boy?

Rasek [7]

Let William be x years old.

Thomas = (4 + x) years

In five years,

William = (x + 5) years

Thomas = 4 + x + 5 = (9 + x) years

Given, in five years sum of their ages is 24.

x + 5 + 9 + x = 24

2x + 14 = 24

2x = 24 - 14

2x = 10

x = $\frac{10}{2}$

x = 5

Hence, William is 5 years old and Thomas is 9 years old.
