Answer:
Perimeter = 86.4 (m)
Step-by-step explanation:
A square (with side x) has an area of 466.56 (m^2)
=> x^2 = 466.56
=> x = sqrt(466.56) = 21.6
=> Perimeter of this square: P = 4(x) = 4(21.6) = 86.4 (m)
Hope this helps!
Answer:
r = 13
Step-by-step explanation:
r-6=7
Add 6 to each side
r-6+6=7+6
r = 13
<span>The solution to the problem is as follows:
W=Fd=mad=425*1.8*66
=50490 J
Therefore, it takes </span><span>50490 J of work the crane will do to accelerate the beam upward at 1.8 m/s^2.

Primary equation: A(x)= (5y)(3X)
Secondary equation: 5y+3X=1000
y=200-(3X)/5
A(x)=3X(1000-3X)
A(x)=3000X-9X²
Now, find the derivative of A(x) to find the max... here's the work for that, or you could guess and check.
A'(x)=3000-18X
Set derivative equal to 0
0=3000-18X
166.6666666=X
Now test the intervals
(0,166.6666) (166.66666, 1000)
1st derivative is + 1st derivative is -
Plug the X value back into the secondary equation
5y+3(166.666666)=1000
5Y=500
Y=5
Answer:
X= 166.6666666666
Y=5
Please note, this is entry level calculus, and your teacher may expect you to use a different, longer route such as guess and check.
