Which expression is equivalent to log3(x + 4)?

Answer:

log[3(x+4)] is equal to log(3) + log(x + 4), which corresponds to choice number three.

Step-by-step explanation:

By the logarithm product rule, for two nonzero numbers a and b,

\log{(a \cdot b)} = \log{(a)} + \log{(b)}.

Keep in mind that a logarithm can be split into two only if the logarithm contains the product or quotient of two numbers.

For example, 3(x + 4) is the number in the logarithm \log{[3(x + 4)]}. Since 3(x + 4) is a product of the two numbers 3 and (x + 4), the logarithm \log{[3(x + 4)]} can be split into two. By the logarithm product rule,

\log{[3(x + 4)]} = \log{(3)} + \log{(x + 4)}.

However, \log{(x + 4)} cannot be split into two since the number inside of it is a sum rather than a product. Hence choice number three is the answer to this question.

A 90 oz. bottle of shampoo is sold for $18.95. What is the price per ounce
Veseljchak [2.6K]

This sets up as a very commonly  used proportion.

90 oz / 18.95 = 1 oz / x             Cross multiply

90 x = 18.95                              Divide by 90

x = 18.95 / 90

x = 0.21 dollars or 21 cents.

So each ounce of shampoo costs 0.21 dollars or 21 cents.

This is a very handy way to check best deals. Stores have trained us for years to believe that the more we buy of a brand, the better the price. It isn't always true. Sometimes buying the  smaller quantity is the better deal. There is only one way to be sure and that's to do a proportion like this one.

Try this is an example. The same company makes a smaller container of shampoo of 45 oz for 9.15. How much is 1 oz and which is the better deal? You should get 0.20333 dollars so this is marginally (just) the better deal.

Given:

The set of pair and graphs.

To find:

The domain and range.

Solution:

We know that,

Domain is the set of x-values or input values.

Range is the set of y-values or output values.

(a)

The given set of ordered pairs is

{(-3,3),(5,5),(-3,2),(5,3)}

Here, the x-coordinates are -3, 5, -3, 5.

A set contains distinct values.

Therefore, the domain is {-3,5}.

(b)

The graph is given.

From the given graph the set of ordered pairs is

{(-2,1),(-1,0.5),(-1,3),(0,0),(0,2),(1,0.5),(1,3)(2,1)}

Here, the y-values are 1, 0.5, 3, 0, 2, 0.5, 3, 1.

Therefore, the range is {0, 0.5, 1, 2, 3}.

(c)

The graph is given.

From the given graph the set of ordered pairs is

{(-2,3),(-1,3),(0,1),(2,4)}

Here, the x-values are -2, -1,0, 2.

Therefore, the domain is {-2,-1,0,2}.
