Hey there!

The answer is false. A 90 degree angle is called a right triangle. Any angle less than 90 degree is called an acute angle. Any angle more than 90 degree is called an obtuse angle

False, it is obtuse, because it will be wider

A town has a population of 17000 and grows at 2.5% every year. To the nearest year, how long will it be until the population wil

andre [41]

Answer:

6 years

Step-by-step explanation:

we know that

The equation of a exponential growth is equal to

$y=a(1+r)^x$

where

y ----> is the population

x ---> is the number of years since now

a ---> is the initial value or y-intercept

r ---> is the rate of change

we have

$a=17,000\ people$

$r=2.5\%=2.5/100=0.025$

substitute

$y=17,000(1+0.025)^x$

$y=17,000(1.025)^x$

For y=19,600

substitute in the exponential equation and solve for x

$19.600=17,000(1.025)^x$

$(19.600/17,000)=(1.025)^x$

apply log booth sides

$log(19.600/17,000)=log(1.025)^x$

$log(19.600/17,000)=xlog(1.025)$

$x=log(19.600/17,000)/log(1.025)=6\ years$
