alexandr1967 [171]
Use the definition of a logarithm
If Log(x) = y ; then b^y = x

Log_{2} (Log_{5} (x)) = 3 \\ \\ 
2^{3} = Log_{5} (x) 
\\ \\ 8 = Log_{5} (x) 
\\ \\ x = 5^{8} 
\\ \\ x = 390,625

Answer:

7+9+11+3=30 (total)

(13)-

\frac{9}{30}  =  \frac{3}{10}

(14)-

\frac{13}{52}  =  \frac{1}{4}

(15)-

\frac{7}{30}  +  \frac{11}{30}  =  \frac{18}{30}   =  \frac{9}{15}  =  \frac{3}{5}

(16)-

\frac{13}{52}  +  \frac{13}{52}  =  \frac{26}{52}  =  \frac{1}{2}

(17)- Experimental and theoretical are not the same but within 10% of each other .

Find the equation of the exponential function represented by the table below:
UNO [17]

Answer:

Step-by-step explanation:

If this is an exponential function, it is of the form

y=a(b)^x  where x and y are coordinates from your table, a is the intial value, and b is the growth/decay rate.  To find out what the equation is that represents this data, choose 2 points and solve first for a and then for b.  Just a hint:  If at all possible, choose the coordinate that gives you an x of 0.  You'll see why in a minute.  

I chose the first 2 points from your table: (0, .2) and (1, .8).  Solving first for a:

.2=a(b)^0  The reason to choose the x of 0 as one of your points is because anything raised to the power of 0 is 1.  So our equation then becomes:

.2=a(1) so

a = .2   Easy enough.  

Now use that value along with the other coordinate to solve for b:

.8=.2(b)^1  b to the first is just b, so,

.8 = .2b

Divide both sides by .2 and you'll get that

b = 4

The equation, then, is

y=.2(4)^x which is growth, since the value for b is greater than 1.
