Answer:
<em>The price per share after 4 hours is $21.43</em>
<em>The price per share after 20 hours is $4.15</em>
Step-by-step explanation:
<u>Equations</u>
The price of the company's stock is initially at $25.75 per share. Each hour the price drops by $1.08. This condition can be modeled by the function:
Where t is the time in hours.
The sign means the function is decreasing as time passes.
When t=4 hours, the price will be:
The price per share after 4 hours is $21.43
Now find the price when t=20 hours
The price per share after 20 hours is $4.15

Answer:
Exponential form: 5^3
Expanded form: 5*5*5
Standard form: 125
Step-by-step explanation:
The exponential form is when we use the ^ symbol. The base is the number before the ^ and the exponent is the number after the ^. When five is cubed, the base is 5 and the exponent is 3.
Therefore, the exponential form is 5^3. We can also write it with a little 3 on the top right corner of the 5, that is .
On the expanded form we use multiplications. The exponent number tells us how many times to multiply the base number by itself. When 5 is the base and 3 the exponent, we have to multiply 3 times the number 5 by itself. That is 5*5*5.
The standard form is the result of the calculations we wrote before. The easiest way is to get it from the expanded form.
5*5*5 = 25*5 = 125
