All the edges of a cube are expanding at a rate of 4 in. per second. How fast is the volume changing when each edge is 10 in. lo

Greeley [361]

Given:

All the edges of a cube are expanding at a rate of 4 in. per second.

To find:

The rate of change in volume when each edge is 10 in. long.

Solution:

Let a be the edge of the cube.

According to the question, we get

$\dfrac{da}{dt}=4\text{ in./sec}$

$a=10\text{ in.}$

We know that, volume of a cube is

$V=a^3$

Differentiate with respect to t.

$\dfrac{dV}{dt}=\dfrac{d}{dt}a^3$

$\dfrac{dV}{dt}=(3a^2)\times \dfrac{da}{dt}$

Putting the given values, we get

$\dfrac{dV}{dt}=(3(10)^2)\times 4$

$\dfrac{dV}{dt}=3(100)\times 4$

$\dfrac{dV}{dt}=300\times 4$

$\dfrac{dV}{dt}=1200\text{ in}^3\text{/sec}$

Therefore, the rate of change in volume 1200 cubic inches per second.

Express 20p of a fraction of 5,<br> Write 0.065 as a fraction

Umnica [9.8K]

To write .065 as a fraction you have to write .065 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
.065 = .065/1 = 0.65/10 = 6.5/100 = 65/1000

Identify the monomial function described as odd or even, and indicate whether a is positive or negative.

Igoryamba

Answer:

Case 1: As x > 0 increases, f(x) increases. As x < 0 decreases, f(x) decreases.

It is an 'odd' function with 'positive' a.

Case 2: As x > 0 increases, f(x) decreases. As x < 0 decreases, f(x) decreases.

It is an 'even' function with 'negative' a.

Case 3: As x > 0 increases, f(x) increases. As x < 0 decreases, f(x) increases.

It is an 'even' function with 'positive' a.

Case 4: As x > 0 increases, f(x) decreases. As x < 0 decreases, f(x) increases.

It is an 'odd' function with 'negative' a.

Step-by-step explanation:

Let us consider a monomial function:

f(x) = axⁿ

Case 1:

As x > 0 increases, f(x) increases. As x < 0 decreases, f(x) decreases.

This happens only if a is 'positive' and n is 'odd'. So, it is an 'odd' function with 'positive' a.

Case 2:

As x > 0 increases, f(x) decreases. As x < 0 decreases, f(x) decreases.

This happens only if a is 'negative' and n is 'even'. So, it is an 'even' function with 'negative' a.

Case 3:

As x > 0 increases, f(x) increases. As x < 0 decreases, f(x) increases.

This happens only if a is 'positive' and n is 'even'. So, it is an 'even' function with 'positive' a.

Case 4:

As x > 0 increases, f(x) decreases. As x < 0 decreases, f(x) increases.

This happens only if a is 'negative' and n is 'odd'. So, it is an 'odd' function with 'negative' a.
