For the function f(t)=pe rt , if p=9 and r=0.09 then what is the value of f(9) to the nearest tenth

1 answer:

7 0

Answer: f(9) = 20.2 .
_______________________________
Explanation:
_______________________________
f(9) = pe^(r*t) = 9* e^(0.09 * 9) ;
_______________________________
Note: 0.09 *9 = 0.81 .
______________________________
→ f(9) = pe^(r*t) = 9* e^0.81 ) ;
_______________________________
Note: e^(0.81) = 2.24790798668.

f(9) = 9 * 2.24790798668 ;

= 20.2311718801 ;

→ Round to the nearest tenth:

f(9) = 20.2 .

Irving can I remember the correct order of the five digits on his ID number he does remember that the ID number contains the dig

Cloud [144]

Answer: $\frac{27}{125}$

Step-by-step explanation:

Here the total numbers are 1, 4, 3, 7, 6

Since the total number of possible arrangement = $5\times 5 \times5 \times 5 \times 5=5^5$

The total number of the odd numbers in the given numbers = 3

Thus the possible arrangement that the first three digits will be odd numbers = $3\times 3\times 3\times 5\times 5=3^3\times 5^2$

Thus, the probability that the first three digits of Irvings ID number will be odd numbers = the possible arrangement that the first three digits will be odd numbers / total possible arrangement = $\frac{3^3\times 5^2}{5^5} = \frac{3^2}{5^{5-2}}$
