Answer: A. A=(1000-2w)*w B. 250 feet
C. 125 000 square feet
Step-by-step explanation:
The area of rectangular is A=l*w (1)
From another hand the length of the fence is 2*w+l=1000 (2)
L is not multiplied by 2, because the opposite side of the l is the barn,- we don't need in fence on that side.
Express l from (2):
l=1000-2w
Substitude l in (1) by 1000-2w
A=(1000-2w)*w (3) ( Part A. is done !)
Part B.
To find the width w (Wmax) that corresponds to max of area A we have to dind the roots of equation (1000-2w)w=0 ( we get it from (3))
w1=0 1000-2*w2=0
w2=500
Wmax= (w1+w2)/2=(0+500)/2=250 feet
The width that maximize area A is Wmax=250 feet
Part C. Using (3) and the value of Wmax=250 we can write the following:
A(Wmax)=250*(1000-2*250)=250*500=125 000 square feets
Answer:
Domain = {-2, 2, 3, 4, 5}
Range= {6, 0, 6, -1, 3)
It is a function
Step-by-step explanation:
It is a function because there is only one y value for each x value
Answer: 62-48=14
Step-by-step explanation: therefor the bottom right hand corner is 14.
hope this is right ;)
Answer:
480 cubic feet
Step-by-step explanation:
Given length of self storage = 8 feet
width of self storage = 6 feet
height of self storage = 10 feet.
Volume of rectangular object is calculated by formula
volume = length * width * height
substituting the value of length , width and height of self storage room in above formula we have
volume of self storage room = 8 * 6* 10 cubic feet= 480 cubic feet
