Answer:
1/5? 0.2?
Step-by-step explanation:
The max occurs when length=width
so
perimiter=16
and L=W
P=2(L+W)
16=2(L+L)
16=2(2L)
16=4L
4=L
the dimentions are length and width are 4 meters
aera will be 16 square meters
A .E is 7 inches for the left arm
E is 8 1/2 inches for the left foot
the inputs look like the length of the arm (ie x)
the outputs are the length of the foot
<span>rate of change=<span>change in y change in x</span></span> use the data you gathered or this equation they give you = 0.860 • + 3.302
B. find the difference in y, then the difference in x, then divide (y over x) to get the slope
8-7/7 1/2-6 1/2
= 1/1
=1
C.you plug in any (x,y) point you used to find the slope
Solve for B
y = mx+b
y = 1*x + b
7.5 = 1*8 + b
b =
7.5 - 8 = -0.5
<span>y = x - 0.5</span>
Hope this helps
In 4 hours they will be 400 miles apart 4 times 55 is 220 and 4 time 45 is 180 since there going in opposer directions add the miles together and it equals 400 so it takes 4 hours
