Answer:
If each side of pentagon is doubled then its perimeter will also be doubles. The new perimeter is 30 feet.
Step-by-step explanation:
Let the length of all five sides of pentagon = <em>v, w, x, y</em>, and <em>z</em>.
Perimeter of pentagon = Sum of lengths of its all five sides = (<em>v + w + x + y + z</em>) = 15 feet
If each side of pentagon is doubles then,
New perimeter of pentagon = (2<em>v + </em>2<em>w + </em>2<em>x + </em>2<em>y + </em>2<em>z</em>)
= 2 (<em>v + w + x + y + z</em>)
= 2 (15)
= 30 feet
Therefore, if each side of pentagon is doubled then its perimeter will also be doubled.
The correct option is D.
The initial value of the stock is $575 and it doubles every 8 years, this means that, in the next eight year the value of the stock will be 2 * 575 = $1150.
This amount too will double in the next eight year and the value will become 2* 1150 = $2,300.
Therefore, in 16 years time the share will be worth $2,300.00.
