Answer:
Step-by-step explanation:
Let the edge of the cube be a .
Given
Volume V = a³

= 3a² x 2
= 6a²
If a = 40 cm

= 9600 cm³/s .
This is an exponential growth problem. Exponential growth can be expressed mathematically in the following way:

.
Parameter a presents initial amount.
Parameter r is percentage increase.
Parameter t is time.
An equation that would describe given problem is:

t is the time in years.
I attached the graph of this function.
Answer:
Qu. 8 = A (50) = 25w as 125w x 125l = Area ; this because perimeter 500ft would always be a 3:5 ratio to the larger area. Therefore perimeter is 125+125 +125 +125 and = 500ft. However we can prove if 125 is any length or width then A(50)= 1/5 = 25 Qu 9)= I think last 2 are a function. Qu 10) Answer B is correct.

<em><u>Answer is below</u></em>
Step-by-step explanation:
<u><em>3+5(2−3)−6</em></u>
<u><em>=3+(5)(−1)−6</em></u>
<u><em>=3+−5−6</em></u>
<u><em>=3+−11</em></u>
<u><em>=−8</em></u>
<u><em>So therefore, your answer would be -8</em></u>
Answer: If it's something like who got the better deal then Tony did.
Step-by-step explanation: The reason I say that is the fact that the 20% off made the sweatshirt $38.40 cause $9.60 was taken off!
