Divide a 8 foot sandwich into pieces that are 3/4 of a foot long. How many 3/4 foot pieces are there?

Vinvika [58]

The answer is not a whole number, so I'm not sure if I am 100% right.

The answer I got was 10.66666667 Pieces. Of course you wouldn't type that many 6's, just as many as it asks for. lol

A potter forms a piece of clay into a cylinder. As he rolls it, the length, L, of the cylinder increases and the radius, r, decr

stepan [7]

Answer:

The radius is decreatsing at a rate 0.78 cm per second.

Step-by-step explanation:

We are given the following in the question:

$\dfrac{dl}{dt} = 0.7\text{ cm per second}$

Instant radius,r = 2 cm

Instant length,l = 9cm

The radius of the cylinder decreases.

Volume of cylinder =

$V =\pi r^2l$

Since the volume of the cylinder does not changes, we can write:

$\dfrac{dV}{dt}=0$

Rate of change of volume:

$\dfrac{dV}{dt} = \pi(2r\dfrac{dr}{dt}l + r^2\dfrac{dl}{dt})$

Puttiung values, we get

$0 = \pi(2(2)\dfrac{dr}{dt}(9) + (2)^2(0.7))\\\\\dfrac{dr}{dt}=-\dfrac{4\times 0.7}{4\times 9} \approx -0.78$

Thus, the radius is decreatsing at a rate 0.78 cm per second.

Convert 13/8 to a mixed number

Effectus [21]

Given:
13/8

First you have to see how many times 8 can go into the number 13. If you look, 8 can only go into 13 one time, leaving 5 left over.
13-8 = 5
1 with 5 left over
(Rather than writing 8/8, you must simplify to 1 to make it less redundant)

Since there is 5 left over from 8, you would then place it into the numerator place to get:
1 5/8

I hope this helps!

Let f(x) = Square root x. Find g(x), the function that is f(x) shifted up 7 units and left 1 units.

Rudik [331]

$~\hspace{10em}\textit{function transformations} \\\\\\ \begin{array}{llll} f(x)= A( Bx+ C)^2+ D \\\\ f(x)= A\sqrt{ Bx+ C}+ D \\\\ f(x)= A(\mathbb{R})^{ Bx+ C}+ D \end{array}\qquad \qquad \begin{array}{llll} f(x)=\cfrac{1}{A(Bx+C)}+D \\\\\\ f(x)= A sin\left( B x+ C \right)+ D \end{array} \\\\[-0.35em] ~\dotfill$

$\bullet \textit{ stretches or shrinks horizontally by } A\cdot B\\\\ \bullet \textit{ flips it upside-down if } A\textit{ is negative}\\ ~~~~~~\textit{reflection over the x-axis} \\\\ \bullet \textit{ flips it sideways if } B\textit{ is negative}\\ ~~~~~~\textit{reflection over the y-axis} \\\\ \bullet \textit{ horizontal shift by }\frac{ C}{ B}\\ ~~~~~~if\ \frac{ C}{ B}\textit{ is negative, to the right}\\\\ ~~~~~~if\ \frac{ C}{ B}\textit{ is positive, to the left}$

$\bullet \textit{ vertical shift by } D\\ ~~~~~~if\ D\textit{ is negative, downwards}\\\\ ~~~~~~if\ D\textit{ is positive, upwards}\\\\ \bullet \textit{ period of }\frac{2\pi }{ B}$

keeping in mind that template, let's take a looksie

$f(x) = \sqrt{x}\implies f(x) = A\sqrt{Bx + C}+D\implies f(x) = 1\sqrt{1x+0}+0 \\\\\\ \begin{cases} D = \stackrel{\textit{shifted up}}{+7}\\ C = \stackrel{\textit{left shift}}{+1} \end{cases}~\hspace{4em}g(x) = 1\sqrt{1x+1}+7\implies g(x) = \sqrt{x+1}+7$
