Answer:
$500 would be better, for 4 months only...
Step-by-step explanation:
Perimeter of a Rect.= 2(l+b)
b= x
l= 2x
Equation
152= 2(2x+x)
152= 2(3x)
152= 6x
x= 25.33
2x= 50.66
Therefore length is 50.66m and breadth is 25.33m
Answer:
A
Step-by-step explanation:
The velocity of a moving body is given by the equation:

Is the velocity is <em>positive </em>(v>0), then our object will be moving <em>forwards</em>.
And if the velocity is negative (v<0), then our object will be moving <em>backwards</em>.
We want to find between which interval(s) is the object moving backwards. Hence, the second condition. Therefore:

By substitution:

Solve. To do so, we can first solve for <em>t</em> and then test values. By factoring:

Zero Product Property:

Now, by testing values for t<1, 1<t<4, and t>4, we see that:

So, the (only) interval for which <em>v</em> is <0 is the second interval: 1<t<4.
Hence, our answer is A.
