# Question: 22 is what percent of 40?
## Answer: 55 percent, which is equivalent to saying 22 out of 40 is 55%
### How to calculate 22 is what percent of 40
22 ÷ 40 × 100
= (22 × 100) ÷ 40
= 2200 ÷ 40
= 55
Now we have: 22 is what percent of 40 = 55%
## A simple step by step solution for calculating 22 is what p... |

# Solving the Mystery of the Cube Root of 125
As children, we are often introduced to the concept of mathematical roots. We learn how to find the square root and cube root of numbers, but these are often limited to small numbers. However, as we progress in our mathematical journey, we begin to encounter more complex p... |

# Golden Triangle
The Golden Triangle, often known as the sublime triangle, is an isosceles triangle. The ratio of the side ‘a’ to base ‘b’ is equal to the golden ratio, $$\frac{a}{b} = \varphi$$.
Considering the above figure, the vertex angle will be:.
$$\theta = 2sin^{-1}(\frac{b}{2a}) = 2sin^{-1}(\frac{1}{2\varphi... |

# How do you factor z^3 + 7z + 7^2 + 7?
Jun 13, 2017
It can be factored in two different ways. Check out the Explanation! :)
#### Explanation:
Apply the power function when it appears on a constant value:
${z}^{3} + 7 z + {7}^{2} + 7 = {z}^{3} + 7 z + 49 + 7 = {z}^{3} + 7 z + 56$.
We can now do two different fact... |

## Summary and examples
The general equation of a quadratic function is:
, and are called parameters. , because otherwise it is no quadratic function.
The graph of a quadratic function is a parabola. There are two types, one that opens up and one that opens down, depending on the parameter .

Expansion of (a ± b)$$^{2}$$
A binomial is an algebraic expression which has exactly two terms, for example, a ± b. Its power is indicated by a superscript. For example, (a ± b)2 is a power of the binomial a ± b, the index being 2.
A trinomial is an algebraic expression which has exactly three terms, for example, a ±... |
# How do you solve 4 sqrt (x) = 8 + 2 sqrt (x)?
Sep 13, 2015
color(green)(x = 16
#### Explanation:
We are given that $4 \sqrt{x} = 8 + 2 \sqrt{x}$
Transposing $2 \sqrt{x}$ to the left hand side, we get:
$4 \sqrt{x} - 2 \sqrt{x} = 8$
$\left(4 - 2\right) \sqrt{x} = 8$
$2 \sqrt{x} = 8$
Divising both sides by 2, w... |
## - Interval Bisection
With this method we repeatedly bisect the interval containing the root in order to improve the approximation.
LESSON 1
Given that $$x^3-3x^2=1-x$$ has a root between 2 and 3, find this root to 1 decimal place using the bisection method.
SOLUTION
$x^3-3x^2=1-x$
Rewrite the equation in the form ... |
