Is there any positive number b so that the expression logb (0) makes sense? Explain how you know?
topjm [15]

Answer:

No.

Step-by-step explanation:

The logarithm of a number to the base b of a certain number  is the exponent

to which the base b is raised to equal the given value.

So say we have  logb y = a, then

y = b^a

So if y = 0 then

0 = b^a

If b is a positive number then there is no value of a that makes y = 0.

for example y = b^0 = 1, y = b^1 = b  etc.

Find any domain restrictions on the given rational equation
rodikova [14]

Answer:

x ≠ -4, -1, 3

Step-by-step explanation:

\frac{x}{x+4}+ \frac{12}{x^2}  +5x+4 = \frac{8x}{5x-15}

12/(x^2+5x+4) = 8x/(5x-15)

\frac{12}{((x+1)(x+4))}  = \frac{8x}{(5(x-3))}

The Edwards family's bill for dinner is $42.95. How much should they tip their server? (assuming they tip the normal 15%.)
OLEGan [10]

Answer:

Tip given to the server be $6.44 .

Step-by-step explanation:

As given

The Edwards family's bill for dinner is $42.95.

The normal tip is  15%.

15% is written in the decimal form .

= \frac{15}{100}

= 0.15

Tip given to the server = 0.15 × Cost of the dinner

Putting all the values in the above

                                     = 0.15 × 42.95

                                     = $6.44 (Approx)

Therefore the tip given to the server be $6.44 .
