Answer:

Step-by-step explanation:

In choices a and b, the bases are positive numbers greater than 1, and so these are growth functions.  In c and d, the bases are between 0 and 1, and thus these are decay functions.

In the second problem we have 3ln(x + 1).  Rewrite this as ln(x + 1)^3.

We also have 9ln(x - 4).  Rewrite this as ln(x - 4)^9.

Because of the + sign connecting ln(x + 1)^3 and ln(x - 4)^9, these two logs combine to form

ln [ (x + 1)^3 ] * (x - 4)^9 (the log of a product).

Now we have:

ln [ (x + 1)^3 ] * (x - 4)^9  -  4ln(x + 7), or:

       [ (x + 1)^3 ] * (x - 4)^9

ln ------------------------------------

                (x + 7)^9

Answer:

Step-by-step explanation:

Looking at the table

a) f(x) = 0.35(10)^x is a growth function. The rate of change is greater than one.

b) f(x) = 8(3.75)^x is a growth function. The rate of change is greater than one.

c) f(x) = 2.1(0.79)^x is a decay function. The rate of change is lesser than 1

d) f(x) = 4.3(0.28)^x is a decay function. The rate of change is lesser than 1

5) 3ln(x + 1) + 9(ln x - 4) -4ln( x +

7)

Recall

alnb = b^a. Therefore, the expression becomes

ln(x + 1) ^3 + ln(x -4x)^9 - ln(x + 7)^4

= ln [(x+1)^3 × l(x - 4)^9]/(x + 7)^4

An engineer is planning a new water pipe installation. The circular pipe has a diameter of d=20\text{ cm}d=20 cmd, equals, 20, s
aivan3 [116]

Answer: The answer is 314.28 cm² (approx.).


Step-by-step explanation:  Given that an engineer is going to install a new water pipe. The diameter of this circular pipe is, d = 20 cm.

We need to find the area 'A' of the circular cross-section of the pipe.

Given, diameter of the circular section is

\textup{d}=20~\textup{cm}.

So, the radius of the circular cross-section will be

\textup{r}=\dfrac{\textup{d}}{2}=\dfrac{20}{2}=10~\textup{cm}.

Therefore, cross-sectional area of the pipe is

\textup{A}=\pi \textup{r}^2=\dfrac{22}{7}(10)^2=\dfrac{2200}{7}=314\dfrac{2}{7}=314.28~.~.~.~\textup{cm}^2.

Thus, the answer is 314.28 cm² (approx.).

zaharov [31]
We have that
<span>[6x+5]=1+2*(3x+2)
[6x+5]=1+2*3x+2 --------> is not correct ------->1+ 2*(3x+2)=1+2*3x+2*2 

then 
</span>[6x+5]=1+6x+4---------------> [6x+5]=[6x+5] 

<span>this equation is an identity, all real numbers are solutions.</span>
