All you need to do to turn this into function notation is replace V with f(x), or whatever is required. In this case, we should replace the s with an x.
f(x) = x^3
Here, f represents the function acting on x, the input.
As we know, V represents to volume, which means f(x) doesas well. s represented a cube side length, and we chose x to equal the same.
Both of these numbers are negative, so for the sake of ease, let's multiply both by -1 to make the equation 8 / 2/5.
First, let's make 8 into a fraction.
8/1 / 2/5
Now, use "keep, change, flip."
Change the division sign into a multiplication sign...
8/1 * 2/5
And flip 2/5 into 5/2 (the reciprocal).
Now we have 8/1 * 5/2.
What we'll do is multiply the numerators together to find the solution's numerator and the denominators to find the solution's denominator.
8*5 = 40
1*2 = 2
We get 40/2. This can be simplified into 20/1, or just plain 20.
In conclusion, -8 / -2/5 = 20.
Not quite sure if you mean in general or on the calculator, but if you mean in general, all you have to do is take the decimal, put it over 1, and multiply by 10 until you get a whole number. Then, simplify.
Put it it over 1...
Multiply by 10 until whole...
It would be helpful if you rephrased your question...
If you mean:
7 * 1/3, then you could do the following:
Turn 7 into a fraction...
7/1 * 1/3
And then multiply the numerators together for the numerator of the solution and the denominators together for the denominator of the solution.
7*1 = 7
1*3 = 3
You would get 7/3, which simplifies to 2 1/3.
However, if you meant (7*1)/3, you would solve what's in the parenthesis....
And get 7/3, simplifying to 2 1/3.
Either way, the solutions are the same!
In right sided triangles, follow the Pythagorean theorum.
a^2 + b^2 = c^2
This means that the hypotenuse squared is equal to the sum of the squares of the other sides.
To find the height, you can modify it a bit.
c^2 - a^2 = b^2
Let's do an example.
A right triangle has a base length of 5 and a height of 3.
5^2 + 3^2 = hypotenuse^2
25 + 9 = 34 = hypotenuse^2
The square root of 34 is approximately 5.83, therefore a triangle with a length of 5 and a height of 3 will have a hypotenuse of about 5.83.
Let's continue the example to find height.
Suppose the right triangle's height is unknown.
You know the hypotenuse of the triangle is about 5.83, and the length is 3.
5.83^2 - 3^2 = height^2
5.83^2 is approximately 33.99, and 3^2 is 9...
33.99 - 9 = 24.99
The square root of 24.99 is a bit less than 5, but when rounded it equals 5.
This matches the height we got in the first example!
Hope this helps!
The formula for the volume a cylinder is pi(r^2)h.
The formula of the volume of a rectangular prism is l(h)(w).
In both, you are multiplying the base by the height.
You take the surface area of the circle and multiply it by the height.
You take the surface area of the base (rectangle/square) and multiply it by the height.
Well, I assume you are not painting the ground or ceiling, just the walls.
Lateral surface area is the area of the curved part of a curved shape (ex. cylinder, cone, etc.).
Total surface area includes the flat bases as well.
Assuming you are only painting the walls, you would be calculating lateral surface area.
