Answer:
31999.99983
Step-by-step explanation:
calculator :)
Area as a function of width, w is:
a(w)=(w-25)^2+625
for maximum area, the width will be:
a'(w)=2(w-25)+0=0
solving for w we egt
2w-50=0
2w=50
w=25 m
given that the perimeter is 100, the length will be:
100=2(L+W)
solving for L we get:
L=50-W
but W=25m
hence
L=50-25=25 m
thus the maximum area will be:
A=L*W=25*25=625m^2
Answer:
20 m/s
Step-by-step explanation:
Assuming initial velocity is 0:


4m/s^2 * 5s = 20 m/s
Given :
The cost of 5 pounds of boudin is $26.
To Find :
The constant of proportionality that relates the cost in dollars y, to the number of pounds of boudin x .
Solution :
Price per boudin in terms of x and y is :

Price per boudin by given data :

So,

Therefore, the constant of proportionality is
.
Hence, this is the required solution.
