Which equation represents a population of 370 animals that decreases at an annual rate of 11% ?
kati45 [8]

The equation represents a population of 370 animals that decreases at an annual rate of 11% is p=370(0.89)^{t}.

<h3>What is an exponential function?</h3>

It is defined as the function that rapidly decreases and the value of the exponential function is always positive. It denotes with exponent y = a^x

where a is a constant and a>1.

Given that,

A population of 370 animals that decreases at an annual rate of 11%

a = 370, r = 11%

p = a(1-r)^{t}

 =  370(1-0.11)^{t}

p  =  370(0.89)^{t}

Hence, The equation represents a population of 370 animals that decreases at an annual rate of 11% is p=370(0.89)^{t}.

I have some answers the these problems but I just wanna make sure there right.. PLEASE Help??
yanalaym [24]
7x+12+63=180
8x+12=180
Subtract 12 from both sides
8x= 168
=c=21

10x-40=50
Add 40 to both sides
10x=90
X=9

4x+72+2x-12=180
6x +60 =180
Subtract 60 from both sides
6x=120
X=20
