What is a function?The function is defined as a mathematical expression that defines a relationship between one variable and another variable.
What is an inverse function?The inverse function is defined as a function obtained by reversing the given function.
To determine the inverse of a function, all you have to do is switch where x and y are and resolve for y.
We have to find the inverse of the function below :
g(x) = √(x-7)
So after switching x and y,
g(x) = y = √(x - 7)
becomes
x = √(y - 7)
Now, we solve for y regularly.
g(x) = y = √(x - 7)
Solve for y :
⇒ y² = x - 7
⇒ x² = y - 7
⇒ y = x² + 7
Therefore the inverse of g(x) is x² + 7

The trigonometric equations has the following solutions: x = 0 + j · π or x = 0.352π + j · π or x = - 0.352π + j · π, where j is a non-negative whole number.
How to solve a trigonometric equation
In this problem we find the case of a trigonometric equation, whose solutions on the interval [0, 2π] must be found. This can be done by both algebra properties and trigonometric formulae. First, write the entire expression:
tan² x · sec² x + 2 · sec² x - tan² x = 2
Second, use trigonometric formulas to reduce the number of trigonometric functions:
tan² x · (tan² x + 1) + 2 · (tan² x + 1) - tan² x = 2
Third, expand the equation:
tan⁴ x + tan² x + 2 · tan² x + 2 - tan² x = 2
tan⁴ x + 2 · tan² x = 0
Fourth, factor the expression:
tan² x · (tan² x - 2) = 0
tan² x = 0 or tan² x = 2
tan x = 0 or tan x = ± √2
Fifth, determine the solutions to trigonometric equation:
x = 0 + j · π or x = 0.352π + j · π or x = - 0.352π + j · π, where j is a non-negative whole number.

Sum of angles in a quadrilateral.A quadrilateral is a plane figure that has four sides or edges, and also has four corners or vertices. The angles are present at the four vertices or corners of the quadrilateral.
It is formed by joining four non-collinear points. The sum of interior angles of quadrilaterals is always equal to 360 degrees.
How to find the angles.
We can find the value of n using the principle
72° + n = 180°
Collect like terms
n = 180° - 72°
n = 108°
Knowing that the sum of the angles n and angles 2m is equal to 180°, this will give us
2m + 108 = 180°
We collect like terms from here.
2m = 180° - 108
2m = 72°
m = 72/2
m = 36°

Find the slope of the line graphed below.
Answer:
Step-by-step explanation:
To find the slope you would get two points and then you'd use your slope formula. Which is y2-y1 over x2 - x1. The two points I got are (2, -2) and (-3,2), I got this points from the graph. I plugged them in for the x's and y's in the formula and had 2-(-2) on top and -3-2 at the bottom. When I solved the top one which is 2-(-2) I got positive 4. After I solved -3-2 which is in the denominator I got -5. So then I ended with 4/-5. I divided and got -0.8. meaning that 4/-5 or -0.8 is your slope.
(If wrong, I'm sorry might've gotten the points wrong/confused..)

What is the slope of this line? the equation for a line that passes through the points (5,-3) and (-10,15)?
Part 1: Finding slope
The slope is \(\frac{-3-15}{5-(-10)}=\frac{-18}{15}=\boxed{-\frac{6}{5}}\)
Part 2: Finding the equation
Using the point (-10, 15) to substitute into point-slope form,
\(y-15=-\frac{6}{5}(x+10)\\\\y-15=-\frac{6}{5}x-12\\\\\boxed{y=-\frac{6}{5}x+3}\)
Answer:
Using the given points we find that the slope is -1.2 and using the slope-point form we find that the equation of line is y+1.2x = 3.
Step-by-step explanation:
In the question, two points are given, (5,-3) and (-10,15). Using them we can find the slope using the formula, (y2 - y1) / (x2 - x1). So, the slope is
(-3-15) / (5+10) = -18 / 15 = -1.2
Now, we have to find the equation of line. We have two points and a slope. Using any one point and the slope, we can find the equation of line using slope-point form of line. Let us take (5,-3).
(y+3) / (x-5) = -1.2
y+3 = -1.2(x-5)
y+3 = -1.2x + 6
y+1.2x = 3
So, the slope of line is -1.2 and the equation of line is y+1.2x = 3.

Why do we choose 5% as a risk of making error and not 1%
In statistics, the risk of making an error is referred to as a significance level. A significance level represents the probability of making a Type I error, which occurs when a null hypothesis is rejected even though it is true.
The most common significance level used in statistical analyses is 0.05 or 5%. This means that there is a 5% chance of rejecting a true null hypothesis.
In general, the choice of significance level depends on the specific application and context of the statistical analysis.
The 5% significance level is commonly used in scientific research, particularly in the fields of medicine and psychology.
The choice of this level is based on a balance between the risk of making a Type I error and the risk of making a Type II error, which occurs when a null hypothesis is not rejected even though it is false.
A Type II error is often more serious than a Type I error since it may lead to incorrect conclusions about the relationship between variables or the effectiveness of a treatment or intervention.
A 5% significance level provides a reasonable balance between these two types of errors. However, in some situations, a higher or lower significance level may be more appropriate.
For example, in a clinical trial where the consequences of a Type II error are severe, a lower significance level may be used to reduce the risk of this type of error.
