20x(5/100)=1
That is the interest after one year
Add to the principal:20+1=21
The rectangle maximum area will be A=9 square units with the length=3 and the width=3.
<h3>What is area of rectangle?</h3>
Area is defined as the space occupied by a plane or rectangle having length and width in two dimensional plane.
It is given that the perimeter of rectangle is P=12
So from the formula of perimeter of rectangle
2(L+W)=12
L+W=6
L=6-W
Now the area of rectangle will be
A=LxW
A=(6-W)W
Now for maximum area we will find the derivative and equate to zero.




So the area will be

Hence the rectangle maximum area will be A=9 square units with the length=3 and the width=3.

(b) If the weight of the Dog is 12 pounds, it means

Therefore, this is the required solution.
Answer:
Step-by-step explanation:
1.
a)
Find the vertex by completing the square to answer both a and b
d)
x-ints is when y=0
so use quadratic equation for
b^2-20b+200=0
a=1
b= -20
c=200
But notice these imaginary numbers means 0 x intercepts.
