Answer:

${x}^{2} - x - 2 \\ {x}^{2} - 2x + 1 x- 2 \\ {x}^{2} + 1x - 2 x- 2 \\ x(x + 1) - 2(x + 1) \\ = (x + 1)(x - 2)$

A cube with side length m has a volume of 343 cubic centimeters. The following equation shows the volume of the cube.

Tanzania [10]

To find the side length of a cube with a volume of 343, you need to find m to the third power. Solve that and you get 7. m = 7

20 men decided to complete a work in 30 days. but after 6 days 8 men left now in how many day the work will be completed

Serga [27]

First, we convert it into a unit like this

20 workers × 30 days = 600 units work

After leaving the 5 workers, we have 35 days to complete the work.

In 35 days only 15 workers will do the work.

So the work completed in 35 days by 15 workers = 35 ×15 =525 units

Remaining unit = 600 -525 =75 units

This unit would do by 5 workers in (75/5) = 15 days.

So after 15 days, 5 workers should leave the job.

Answer:

your answer is 415 in^3

Step-by-step explanation:

ok the equation in finding the volume of a come is

V= $\pi r^2 \frac{h}{3}$

step 1: plugin

$\pi =3.14$

3.14 x 6^2 x 11/3

3.14x 36 x 11/3 = (6/3 turns into a 2)

113.04x 11/3= 114. 48, when rounded, it's going to give you 415 in^3

Unit activity: exponential and logarithmic functions

nirvana33 [79]

We will conclude that:

The domain of the exponential function is equal to the range of the logarithmic function.
The domain of the logarithmic function is equal to the range of the exponential function.

<h3>Comparing the domains and ranges.</h3>

Let's study the two functions.

The exponential function is given by:

f(x) = A*e^x

You can input any value of x in that function, so the domain is the set of all real numbers. And the value of x can't change the sign of the function, so, for example, if A is positive, the range will be:

y > 0.

For the logarithmic function we have:

g(x) = A*ln(x).

As you may know, only positive values can be used as arguments for the logarithmic function, while we know that:

$\lim_{x \to \infty} ln(x) = \infty \\\\ \lim_{x \to0} ln(x) = -\infty$

So the range of the logarithmic function is the set of all real numbers.

<h3>So what we can conclude?</h3>

The domain of the exponential function is equal to the range of the logarithmic function.
The domain of the logarithmic function is equal to the range of the exponential function.

The volume of a sphere is 972(pi)ft3.

pav-90 [236]

Here are some simple equations that can be a life saver with this stuff :

vol of a sphere =

$v = \frac{3}{4} \pi \: {r}^{3}$

Circumference =

$2 \times \pi \times r$

sorry this might not be very helpful. I haven't don't this since last year. You basically have to work backwards. so plug in 972 for V and then do (3/4)×3.14.

then take the answer u got for ^^ and divide it by 2? not sure.
