Answer:
<u>Similarities</u><u> between a parallelogram and a rectangle</u>
- Quadrilateral (4-sided, two dimensional shape)
- Opposite sides are equal and parallel to each other
- Sum of all the interior angles is 360°
- Diagonals bisect each other
- Adjacent angles are supplementary (sum to 180°)
- Opposite angles are equal
<u>Differences</u><u> between a parallelogram and a rectangle</u>
- A rectangle has four equal interior angles (each are 90°) whereas only the opposite angles in a parallelogram are equal.
- The diagonals of a rectangle are equal in length, whereas the diagonals of a parallelogram are not equal in length.
All rectangles are parallelograms since the opposite sides of a rectangle are parallel, but all parallelograms are not rectangles.
Answer:
Step-by-step explanation:
The formula you will need for this is:
where A is the amount after some decay has happened, A₀ is the intial amount, t is the time in hours, and H is the half-life in hours. Those values for us are:
A = 2 g
A₀ = 25 g
H = 4.95 hrs and
t = ?
Filling in:
Keep in mind that, because of the nature of the exponential form of this equation, you CANNOT simply multiply the 25 by the 1/2. Exponential equations don't work that way. Begin instead by dividing both sides by 25 to get
The goal is to get that t out from its exponential position. Do that by taking the natural log of both sides:

After you take the natural log of the right side, the property allows you to bring the exponent down out front:

Now divide both sides by ln(.5) to get

Simplify the left side out on your calculator to get
and then divide:

Finally, multiply both sides by 4.95 to get
3.643856(4.95) = t so
t = 18.0 hours which is choice C
