Find r<br> 25= r•r•8<br> hurry go fast please
ELEN [110]

Answer:

r = \frac{5}{2\sqrt{2} } \\r = -\frac{5}{2\sqrt{2}}

Step-by-step explanation:

25= r•r•8 ⇔ 25/8 = r²

then

r^{2} =(\frac{5}{2\sqrt{2} } )^{2} \\\\Then\\\\r = \frac{5}{2\sqrt{2} } \\Or\\r = -\frac{5}{2\sqrt{2}}

HELP PLEASE 10 POINTS!!!!!! A country's population in 1993 was 171 million. In 1999 it was 176 million. Estimate the population
Lilit [14]

Let 1993 = time 0 = 0.  

Let 1999 = time 6 = 6  

Let 2012 = time 19 = 19  

So, a = 171 (million). First solve for k.  

176 = 171 e^k6  

176/171 = e^(k*6)  

ln (176/171) = 6k  

k = 1/6 ln (176/171)  

So, in 2012 we have: P(19) = 171 e^(19k), where k = 1/6 ln (176/171)


Hope this helped!
