A cube has an edge of 2 feet. The edge is increasing at the rate of 5 feet per minute. Express the volume of the cube as a funct

Agata [3.3K]

Answer:

$V(m) = (2 + 5m)^3$

Step-by-step explanation:

Given

Solid Shape = Cube

Edge = 2 feet

Increment = 5 feet per minute

Required

Determine volume as a function of minute

From the question, we have that the edge of the cube increases in a minute by 5 feet

<em>This implies that,the edge will increase by 5m feet in m minutes;</em>

Hence,

$New\ Edge = 2 + 5m$

Volume of a cube is calculated as thus;

$Volume = Edge^3$

Substitute 2 + 5m for Edge

$Volume = (2 + 5m)^3$

Represent Volume as a function of m

$V(m) = (2 + 5m)^3$

What is the solution to 5+3(у- 4) =5(y+2) -у

lys-0071 [83]

Answer:

Step-by-step explanation:

5+ 3(у- 4) = 5(y+2) - у

(expand)

5 + 3y - 12= 5y + 10 -y

(combine like terms)

3y - 7= 4y + 10

(move the variables to one side)

-7 = 4y - 3y + 10

(move numbers to one side)

-7 - 10= 4y - 3y

(simplify)

-17 = y or y = -17

I hope this helps!
