Answer:

Step-by-step explanation:

From the given formula,

P(t)=P(0)e^{rt}

\frac{P(t)}{P(0)}=e^{rt}

\text{ln}[\frac{P(t)}{P(0)}]=\text{ln}[e^{rt}]

\text{ln}[\frac{P(t)}{P(0)}]=rt

Now we put the values in the formula to get the values of the blank spaces in the table,

1). \text{ln}[\frac{984}{800}]=5r

   r = \frac{0.207}{5}

   r ≈ 4.2%

2). \text{ln}[\frac{1464}{1200}]=4r

   r = \frac{0.19885}{4}

   r = 0.0497

   r = 5%

3). \text{ln}[\frac{1111.5}{950}]=0.045t

   t = \frac{0.157}{0.045}

   t = 3.5 years

4). \text{ln}[\frac{775}{620}]=3.7t

   t = \frac{0.22314}{0.037}

   t ≈ 6 years

5). \text{ln}[\frac{1066.8}{840}]=8r

   r = \frac{0.239}{8}

   r ≈ 3%

Which numbers are solutions to the equation 30=x2
GaryK [48]

Answer:

x = +√30

Step-by-step explanation:

Please write 30 = x squared as 30 = x^2.

If x^2 = 30, there are two solutions:  x = +√30 and x = -√30.

Several possible answers are given.    x=30−−√ is closest to the correct one, but must be written as x = √30.  Please ask someone how to find the "√" operator in Brainly.  Or, just write "sqrt(      )" instead.
