The given statement, "in 2014 the number of mobile phones was greater than the planet's population" is true (T) because there were 5.8 billion mobile users globally, about 80% of the world's population, and they each had 1.5 devices.

In 2014, there were more mobile phones than there were people on the planet. This is because many people own more than one phone, either as a personal and work phone or as a backup device. Additionally, the rise of low-cost mobile devices in emerging markets, where many people were purchasing their first phones, contributed to the high number of mobile phones relative to the population.

This trend has continued, with the number of mobile phones in the world continuing to grow, outpacing population growth and driving down the cost of devices so that even more people have access to them.

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.

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 length of the base of the triangle is 16 m and the height of the triangle is 10 m

A polygon having three edges and three vertices is called a triangle. It is one of the fundamental geometric forms. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.Use the equation area = 1/2 * base * height to determine a triangle's surface area.

The basic Properties of a triangle :

The length of the base = b m

The height of the triangle = b - 6 m

The area of the triangle = 80 m²

Therefore,

(1/2)*b*(b-6) = 80

⇒ b² - 6b = 160

⇒ b² - 6b - 160 = 0

⇒b² - 16b + 10b - 160 = 0

⇒b(b-16) + 10(b- 16) = 0

⇒(b-16)(b =10) =0

The value of b = 16 and b = -10

The value of b is 16 as -10 is negetive and cannot be the length of the triangle.

The height of the triangle = b-6 = 10 m

Part II.

f(x) = √(x)

Part III.

f(g(x)) = f(3x-4) = √(3x-4)

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)

The net force and magnitude is 54°. The solution has been obtained by using trigonometry.

What is trigonometry?

The primary objective of the branch of mathematics known as "trigonometry" is the study of the sides, angles, and connections of the right-angle triangle.

We are given that three forces are acting on the ring.

So,

A = -128 N + 64 N

A = -64 N

[tex]A_{x}[/tex] = A cos θ[tex]_{A}[/tex]

[tex]A_{x}[/tex] = (-64 N) (cos 180°)

[tex]A_{x}[/tex] = -64 N

[tex]A_{y}[/tex] = A sin θ[tex]_{A}[/tex]

[tex]A_{y}[/tex] = (-64 N) (sin 180°)

[tex]A_{y}[/tex] = 0 N

B[tex]_{x}[/tex] = B cos θ[tex]_{B}[/tex]

B[tex]_{x}[/tex] = (128 N) (cos 30°)

B[tex]_{x}[/tex] = 111 N

B[tex]_{y}[/tex] = B sin θ[tex]_{B}[/tex]

B[tex]_{y}[/tex] = (128 N) (sin 30°)

B[tex]_{y}[/tex] = 64 N

R[tex]_{x}[/tex] = A[tex]_{x}[/tex] + B[tex]_{x}[/tex]

R[tex]_{x}[/tex] = -64 N + 111 N

R[tex]_{x}[/tex] = 47 N

R[tex]_{y}[/tex] = A[tex]_{y}[/tex] + B[tex]_{y}[/tex]

R[tex]_{y}[/tex] = 0 N + 64 N

R[tex]_{y}[/tex] = 64 N

[tex]R = \sqrt{R_{x}^{2} +R_{y}^{2} }[/tex]

[tex]R = \sqrt{(47 N)^{2} +(64 N)^{2} }[/tex]

R = 79 N

θ = [tex]tan^{-1}(\frac{R_{y} }{R_{x}} )[/tex]

θ = [tex]tan^{-1}(\frac{64 }{47} )[/tex]

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.

This plot is the curve -

1 $100 winner =$100

2 $25 winner =$50

5 $10 winners =$50

All together it will add up to $200

So then we do the prize money minus our starting cost which is $400-$200. Which equals $200. You will give back $200 as prize money, and then $200 is a profit you will keep.

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
