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 -

y = 3^x

Therefore, the exponential function is y = 3^x.

The area of the top surface of the d) Vanilla cake is 50.24 square inches and the Chocolate cake is 78.5 square inches.

The formula for the area of a circle is π times the radius squared. To find the top surface area of the cakes, we first need to find the radius of each cake by dividing the diameter by 2.

The radius of the vanilla cake is 4 inches and the radius of the chocolate cake is 5 inches. Then, we can use the formula: π times the radius squared to find the area of each cake. Using π = 3.14, we get:

Answer: (-5,1)

Step-by-step explanation:

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.

Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are several distinctive trigonometric identities that relate a triangle's side length and angle.

Trigonometry equations known as trig identities are used often to comprehend various mathematical aspects and to solve trigonometry and geometry-related issues. Knowing essential trig identities aids in remembering and comprehending crucial mathematical concepts as well as in resolving a variety of mathematical issues.

The Pythagorean trigonometric identity, commonly known as the Pythagorean identity, is an identity that uses trigonometric functions to represent the Pythagorean theorem. It is one of the fundamental relationships between the sine and cosine functions, along with the sum-of-angles equations.

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.

Part I.

g(x) = 3x-4

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)

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 we have 69. 22 can go into 69. As you did it, 22 can only go in three times. So we add the 3 to the top and put 66 on the bottom, as 22*6 = 66. Now, we subtract 69 and 66. This gives us 3. Now, we bring down the 1. So instead of 3 as you have it, it'd be 31. 22 can go into 31 one time. So, we put our 1 up top and put our 22 on the bottom, as 22*1 = 22. Then, we finish by subtracting 31 from 22, which equals 9.

Answer:

$200

Step-by-step explanation:

If tickets cost $1/ticket then it'll be $400 for all the tickets combined. If you add all the winners up then you will get $200 that is given back to them.

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.

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

The lateral area of the cone is approximately 401 cm²

Let's call the radius of the circular base of the cone "r". We know that the area of the circular base is 16π cm², so:

r² = 16

r = 4

Now that we know the radius, we can find the slant height. The slant height is 4 times the radius, so:

4 * r = 4 * 4 = 16

The lateral area of a cone is equal to π times the slant height times the radius of the base, so:

lateral area = π * r * slant height = π * 4 * 16 = 128π

Using π ≈ 3.14
