Answer: +25

Step-by-step explanation: Automatically, you can change the subtraction problem to an addition problem by adding the opposite.

So now that becomes 17 + (+8) which we can

rewrite as 17 + 8 which simplifies to +25.

If a fair die is rolled 3 times, what is the probability, to the nearest thousandth, of getting exactly 2 fives?
Alexxandr [17]

Answer:

The answer is .578 you just do 5/6 due to the fact that there are 6 sides on a die and 1 side is a 2 so if you don’t get a two there is 5 sides left so you do 5/6 to the power of 3 leaving you with .578 and some

What is the derivative of ln(lnx^3)
chubhunter [2.5K]

the derivative of ln(lnx^3) is \frac{1}{x(lnx)} .

<u>Step-by-step explanation:</u>

Here we have to find the derivative of ln(lnx^3) , Let's find out:

We have , ln(lnx^3) , Let's differentiate it w.r.t x :

⇒ \frac{d(ln(lnx^3))}{dx}

Let lnx^3 = u

⇒ \frac{d(ln(u))}{dx}

⇒ \frac{1}{u} (\frac{d(u)}{dx} )

⇒ \frac{1}{u} (\frac{d(ln(x^3))}{dx} )

Let x^3=v

⇒ \frac{1}{u} (\frac{d(ln(v))}{dx} )

⇒ \frac{1}{u}(\frac{1}{v} ) (\frac{d(v)}{dx} )

⇒ \frac{1}{u}(\frac{1}{v} ) (\frac{d(x^3)}{dx} )            

⇒ 3x^2(\frac{1}{u})(\frac{1}{v} )

Putting value of u & v we get:

⇒ 3x^2(\frac{1}{lnx^3})(\frac{1}{x^3} )

⇒ \frac{3}{x(lnx^3)}    { lnx^n = n(lnx)  }

⇒ \frac{3}{3x(lnx)}

⇒ \frac{1}{x(lnx)}

Therefore , the derivative of ln(lnx^3) is \frac{1}{x(lnx)} .

Cube shaped boxes of tissues are shipped to stores in containers. The containers are rectangular prisms. The edges of each tissu
miskamm [114]
I will first calculate the volume of the tissue boxes, that are cubes.

Volume = Base Area x Height

The base area of a cube is a square so:
Base Area (Square) = L^2

In the cube, all sides have the same measure so the height is also L.

L = 6.5 in

Volume (Cube) = L^2 x L = L^3
-> Volume (Cube) = (6.5)^3
-> Volume (Cube) = approximately 275 in^3

Now calculate the Shipping Container volume:
*Represented on the photo, sorry for the bad drawing

The shipping container is a rectangle prism, every rectangle prism have on the base a square, and a square must have every sides with the same measure, knowing that, we know that the two 19.5 inches measures in the question is the length and width of the square. And the 39 inches measure is the Height of the prism.

Base Area (Square) = L^2 = (19.5)^2 = 380,25 in^2 = approx. 380 in^2
Height = 39 in

Volume = Base Area x Height
-> Volume (Prism) = 380 x 39 = 14,820 in^3

Now, to find the greatest number of tissue boxes (cubes) that fit into one container, you just need to divide the container volume by the cube volume and the quotient will be the number of tissue boxes into the container.

Cube's Volume = 275 in^3
Rectangular Prism's Volume = 14,820 in^3

14820 \div 275 = 53.8909....
Answer: 53 tissue boxes.
