Answer:
B or D
Step-by-step explanation:
your x point with be really close to 0 but not quite zero while your y would be 3
Answer:
2(5x-3y-1)
Step-by-step explanation:
perimeter of a rectangle formula:
2l+2w
l=length(2x-3y)5x
w=width(3x-1)
2(2x-3y)+2(3x-1)
4x-6y+6x-2
10x-6y-2
2) all of these numbers have a gcf of 2 so lets divide this equation by 2:
2(5x-3y-1)
hope this helps!
As we knw that the dr/dt = 2
And The area of the circular slick is given by formul
A = (pi)r^2.
Now lets take derivative:
<span>dA/dt=2πrdr/dt
As we knw that radius is 25
so</span><span>dA/dt=2π(25)(2)=100π
which is equal to
=314.16 per minute this is how area is increasing
now for part b
</span><span> t = 4, the radius will have increased to 8 m.
now we will put the values in formula dr/dt
</span>so it will be.dA/dt=2π(8)(2)
=32π
=100.53 is the answer
hope it helps
