10. Express the following function, F(x), as a composition of two functions, f and g: f(g(x)).
F(x)= sqrt(3x-4)
Part I. Find g(x) by identifying the function you are taking the square root of
Part II. Find f(x) by identifying what you are doing to the function you found in Part I. What function is f(x)?
Part III. Verify that
f(g(x))=F(x)
f(g(x))= sqrt(3x-4)
Part I.
g(x) = 3x-4
Part II.
f(x) = √(x)
Part III.
f(g(x)) = f(3x-4) = √(3x-4)
How did we get the values?In Part I, the function F(x) is the square root of 3x-4. Therefore, g(x) is the expression inside the square root: g(x) = 3x-4.
In Part II, the function f(x) is the square root operation applied to its argument, so f(x) = √(x).
Finally, in Part III, we substitute g(x) into f(x) to obtain f(g(x)) = f(3x-4) = √3x-4), which is equal to F(x)
So,
f(g(x))= √(3x-4) = F(x)
Therefore, F(x) = f(g(x)) where f(x) = √(x) and g(x) = 3x-4

Which point in the diagram at the right had a distance of sq of 130
Answer:
S
Step-by-step explanation:
the distance formula (Pythagoras on the right-angled triangle of the coordinate differences) says that
sqrt²(130) = 130 = (-5 - x)² + (5 - y)²
let's try Q
130 = (-5 - 5)² + (5 - 2)² = (-10)² + 3² = 100 + 9 = 109
no, wrong.
let's try S
130 = (-5 - 4)² + (5 - -2)² = (-9)² + 7² = 81 + 49 = 130

Therefore , the solution of the given problem of complementary angles comes out to be 29° and 61° QED.
How do complimentary angles work?Two angles are considered complementary when their sum equals 90 degrees. Two angles are considered submissive when their sum equals 180 degrees. For example, the angles of 40 - 60 degrees complement one another. The difference between a supplementary angle and a supplementing angle is that a Triangle angle has two angles joined to produce a 90 degree angle. When two angles add up to 90 degrees, they are said to be complementary. Alternatively, the complementary angles result in a right angle (90 degrees).
Here,
Given :
Allow x to equal the complementary angle.
Given: x plus 32° the opposite angle
Recognized: Complementary angles sum to 90°
=>x + x + 32° = 90° (Adding the two angles) (Adding the two angles)
2x + 32° = 90° (adding the unknown factors) (adding the unknown variables)
=>2x = 90° - 32° (subtract 32 from both sides) (subtract 32 from both sides)
=> 2x = 58° (assess the right side) (evaluate the right side)
=>x = 29° (split both sides by 2) (divide both sides by 2) (One reply)
=> x + 32° = 61° (Add 32 to x) (Add 32 to x) (The other response)
There are two angles: 29° and 61° QED.

The sum of three consecutive numbers is 42. What are the three numbers?
Answer:
Step-by-step explanation:
Here's a step-by-step explanation to find the three consecutive numbers whose sum is 42:
Let's call the smallest of the three numbers "x".
Since they are consecutive numbers, we can represent the next two numbers as x+1 and x+2.
The sum of these three numbers can be represented as x + (x + 1) + (x + 2) = 42.
Simplifying this equation, we get 3x + 3 = 42.
Subtracting 3 from both sides, we get 3x = 39.
Dividing both sides by 3, we get x = 13.
So, the three consecutive numbers are 13, 14, and 15.

breifly explain, in your words, how the fundamental theorem of calculus made the precise connection between the indefinite and definite integrals. in other words, what was that connection?
Fundamental Theorem of Calculus made a precise connection between the indefinite and definite integrals by stating that the derivative of the definite integral of a function is equal to the original function.
The Fundamental Theorem of Calculus is a key result in mathematics that connects two branches of calculus - the definite integral and the indefinite integral.
The definite integral is used to calculate the total area under a curve. It is defined as the limit of the sum of rectangles with increasing precision, as the width of each rectangle approaches zero.
The definite integral can be calculated using definite limits, for example, from x = 0 to x = 1, and the result is a definite number.
The indefinite integral, on the other hand, is a function that, when differentiated, will give us the original function.
The Fundamental Theorem of Calculus if we have a definite integral of a function f(x) from a to b, then the derivative of this definite integral will be equal to
=> f(x) at x = b - f(x) at x = a.
This provides us with a precise way of calculating areas under curves, and it has many practical applications in fields such as physics, engineering, and economics.

The exponential function for the graph is obtained as y = 3^x.
What is an exponential function?
The formula for an exponential function is f(x) = a^x, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.
Assume that the plot of a function is in the form -
y =ab^x
where the horizontal asymptote is the x-axis.
To find a, look for the coordinate where the curve crosses the y-axis.
In the plot, it is seen that this happens at (0,1).
So, the value of a = 1.
To find b, look for the coordinate where the curve crosses the vertical line at x = 1.
In the plot, it is seen that this happens at (1,3).
Then, b is the number divided by a -
b = 3/1 = 3.

solve the following equations and identify any extraneous roots where applicable: [6 marks total] a) 4^{x+1} = 5^{3x} [3 marks] b) log2x + log2 (x+2) = 3
a) The solution of equation [tex]4^{x+1} = 5^{3x}[/tex] is x = log4/(3log5 - log4).
b) The extraneous roots of equation [tex]\log_{2}x + \log_{2} (x+2) = 3[/tex] is -4 and 2.
a) The first equation is [tex]4^{x+1} = 5^{3x}[/tex].
Now solving the equation.
To solve the equation we take log on both side.
[tex]\log(4^{x+1}) = \log(5^{3x})[/tex]
Using the formula [tex]\log m^n = n\log m[/tex].
Now the equation is
(x+1) log4 = 3x log5
x log4 + log4 = 3x log5
Subtract x log4 on both side, we get
3x log5 - x log4 = log4
Taking common x
x(3log5 - log4) = log4
Divide by (3log5 - log4) on both side, we get
x = log4/(3log5 - log4)
b) The second equation is [tex]\log_{2}x + \log_{2} (x+2) = 3[/tex]
Now solving the equation.
We can write the equation as
[tex]\log_{2}(x(x+2)) = 3[/tex]
Now eliminating the log
x(x+2) = (2)^3
x(x+2) = 8
Now simplify the bracket
x^2 + 2x = 8
Subtract 8 on both side, we get
x^2 + 2x - 8 = 0
Now factor the equation
x^2 + (4-2)x - 8 = 0
x^2 + 4x - 2x - 8 = 0
x(x + 4) -2(x + 4) = 0
Now the factor of the equation is
(x + 4)(x - 2) = 0
Now equating the factor equal to zero.
x + 4 = 0 x - 2 = 0
x = -4 x = 2
Now the solution of equation is -4 and 2.

what does d' measure
The difference between amount of two proportions is measured by D'.
D' is a metric for comparing differences between two proportions. It serves as a gauge for comparing how far apart the two proportions are from one another. It is determined by multiplying the difference between the two proportions by the sum of the standard deviations of the two proportions. The outcome is a measurement of how many standard deviations there are between the two proportions.
In statistical tests like the Chi-Square test or the Z-test, D' is most frequently employed to calculate the difference between two proportions. It is a helpful way to compare two proportions because it indicates whether or not the difference is statistically significant. Given that it takes into consideration the variability of each sample, it is especially helpful when comparing two proportions when the sample sizes are different. In data-mining applications, where it can be used to find correlations between two proportions, D' is also a helpful measure of the separation between two proportions.

The derivative of the equation 2y³ + xy - 6x + 3 at the point (1,1) is 0, and the second derivative is 13.
The derivative of y with respect to x can be calculated by differentiating both sides of the equation with respect to x. This gives us:
[tex]\frac{dy}{dx} = \frac{x}{2y^2} - 5[/tex]
We can evaluate dy/dx at the point (1, 1) by substituting x = 1 and y = 1 into the equation for dy/dx and calculating the result. This gives us:
[tex]\frac{dy}{dx} = \frac{1}{2} - 6 = -5.5[/tex]
The second derivative of y with respect to x can be calculated by differentiating both sides of the equation with respect to x twice. This gives us:
