How will the volume of a cube change if its edge becomes twice as long; 3 times as long; 10 times as long; n times as long?
Mumz [18]

Let, initial side is a.

When side is n times long, new side na.

Initial volume, V_i=a^3

Final volume, V_f=(na)^3=n^3a^3

Change in volume, V_f-V_i=\Delta V =a^3(n^3-1)

For, n = 2 :

\Delta V = 7a^3

n = 3 :

\Delta V = 26a^3

n = 10 :

\Delta V = 999a^3

Hence, this is the required solution.

Write an expression that is the product of two factors and is equivalent to negative 5xminus30. Which expression is the product
andrew-mc [135]

Answer:

-5(x+6)

Step-by-step explanation:

We are asked to write an expression that is the product of two factors and is equivalent to -5x-30.

We can see that greatest common factor of both terms is 5 as 5 times 6 is equal to 30.

Let us factor out negative 5 from both terms as:

-5(x+6)

Since the expression is product of two factors, therefore, our required expression would be -5(x+6).

The total bear population in a certain area is represented by the function P=120(1.016)t , where t is time in years. How would y
Dima020 [189]
1) function: P = 120 (1.0160)^t, t in years

2) weekly function

w = 52 * t = 52t

=> P(w) = 120 (1.016)^ (52w)

3) growth rate = d P(w) / dw

d P(w) / dw = 120 * 52 * [ 1.016 ^ (52w) ] = 6240 [(1.016) ^ (52w) ]

4) solution of the equation

Separate variables

d P(w) = [ 6240 (1.016) ^ (52w)] dw

integrate from w = 0 until w

P(w) - Po = 7599.84 e ^ (0.82514w)

P(w) = Po + 7599.84 e ^ (0.82514w)
