The equation for a trapezoid is a+b/2*h. In this case, we have 3.2+8/2.
So 5.6=22.4/h. The height is 4 feet.
The population of the town after 5 years will be 147089 (approx).
Step-by-step explanation:
The exponential growth equation is given by :-
f(x)=A(1+r)^x...(*)
, where A = initial population , r= rate of growth ( in decimal) and x is time.
As per given , we have
A= 13000
r=2.5%=0.025
x= 5 years
Using (*), the population of the town after 5 years would be :
f(5)=13000(1+0.025)^5=13000(1.025)^5\\\\=13000(1.13140821289)=14708.306767614708.3067676\approx147089
Hence, the population of the town after 5 years will be 147089 (approx).
The equation, p = 4m, is a proportional relationship.
<h3>What is a Proportional Relationship Equation?</h3>
An equation that represents a proportional relationship between two variables such as x and y is, can be expressed as y = kx, where k is the constant of proportionality.
Thus, the constant of proportionality, k = y/x.
The equation p = 4m, shows that the constant of proportionality, k, is 4. This means the variables, p and m are in a proportional relationship.
Therefore, p = 4m represents a proportional relationship equation.
