What is an exponential function?

The exponential function is one of the most important functions in mathematics (though it would have to admit that the linear function ranks even higher in importance). To form an exponential function, we let the independent variable be the exponent.

An exponential function is a function that usually takes the form f(x) = bˣ.

The exponential curve depends on the exponential function and it depends on the value of the x.

where;

b = base

ˣ = power

The general exponential function that models  the data given is:

[tex]y = ce^{kt}[/tex]

According to the (5,5c)

[tex]ce^{5k} = 5c\\\\e^{5k} = 5\\\\5k = ln5\\\\k = \frac{ln5}{5} \\\\k = 0.32[/tex]

Hence , the value of k is 0.32 .

Answer:Th numbers between the bars represents:

A) The age classes, in 5-year ranges

The age classes are indicated by the numbers between the bars, while the numbers within the bars show the popularity of each age group in millions.

Typically, a population pyramid like the one below does not display the number of births that occurred in a single year. However, by looking at the year the population pyramid was developed and deducting from it the corresponding ages shown in the pyramid, one can estimate this information.

complete question:

Look at the age-structure pyramids. The numbers between the bars (in the middle of the graphs) serve as the y-axis. What do these numbers represent?

a) the age classes, in 5-year ranges

b) the number of people born in a particular year

c) the total population(in Million) of males and females

d) the percentage of the population in each age class.

The answer is that, save from 13, all real numbers fall into the domain of (fog)(x).

So, {x|x≠13} option 4 is correct.

A function's domain is the collection of all potential inputs. For instance, all real numbers are in the domain of f(x)=x², and all real numbers are in the domain of g(x)=1/x, with the exception of x=0.

Let y = f(x) be a function where x and y are the independent and dependent variables. If a function f offers a means of successfully generating a single value y while using a value for x to that end, then that selected x-value is said to belong to the domain of f.

The result of multiplying the expression for f(x) by the expression for g(x) is (x + 7)(1/x-13).

This can be expressed much more clearly as (x + 7) (x – 13)

All real numbers, with the exception of 13, can be used to replace x in the expression in this condensed form. This is due to the fact that if we substitute 13 for x, our denominator will be equal to 0, making our formula illogical.

The answer is that, save from 13, all real numbers fall into the domain of (fog)(x).

So, {x|x≠13}

Therefore, option 4 is correct.

The correct statement is "each number in Sabrina’s pattern is 3 times the corresponding number in Martina’s pattern. Each number in Sabrina’s pattern is 3 times the corresponding number in Martina’s pattern."

What is a statement?

A statement in mathematics is a declarative utterance that can only be either true or false. A proposal is another name for a statement. It's important that there be no ambiguity. A sentence can only be true or untrue and not both for it to be a statement.

Given that:

Martina used the rule “Add 2.”

Sabrina used the rule “Add 6.”

The rule that Martina is follow is

M(n) = starting number + 2n

M(n) = 0 + 2n

M(n) = 2n

The rule that Sabrina is follow is

S(n) = starting number + 6n

S(n) = 0 + 6n

S(n) = 6n

S(n) = 3 × 2n

S(n) = 3 × S(n)

Thus Each number in Sabrina’s pattern is 3 times the corresponding number in Martina’s pattern. Each number in Sabrina’s pattern is 3 times the corresponding number in Martina’s pattern.

Answer:

Step-by-step explanation:

You want to know the prices of jelly beans and almonds when you can buy 7 pounds of jelly beans and 9 pounds of almonds for $46, or 5 pounds of jelly beans and 3 pounds of almonds for $20.

The equations describing each purchase can be written as ...

A graphing calculator plots these equations easily, and shows you the solution is (j, a) = (1.75, 3.75).

Jelly beans are $1.75 per pound; almonds are $3.75 per pound.

If you like, you can solve these equations by elimination. We notice the coefficients of 'a' have a simple ratio, so we can eliminate 'a' easily.

  3(5j +3a) -(7j +9a) = 3(20) -(46) . . . . . subtract the first from 3 times the second

  8j = 14 . . . . . simplify

  j = 1.75 . . . . . divide by 8

Substituting into the second equation, we get ...

  5(1.75) +3a = 20

  3a = 11.25 . . . . . . . . . subtract 8.75

  a = 3.75 . . . . . . . . divide by 3

Jelly beans are $1.75 per pound; almonds are $3.75 per pound.

Answer:

(x - 5, y - 1)

Step-by-step explanation:

The x value tells how many units to move right or left.  Right would be adding to x and left would be subtracting from x.

The figure is moved 5 spaces left that would be a rule of x -5.

The y value tells how many units to move up or down.  Up would be addition and down would be subtraction.  In this case, we are moving the figure down one unit so the rule would be y - 1

y = 17.86

Step-by-step explanation:

y = 13.06 + .6x  Substitute in 8 for x

y = 13.06 + .6(8)

y = 13.06 + 4.8

y = 17.86

To find the value of g(3), we need to substitute the value 3 into the expression for G(x) in place of x and then evaluate the resulting expression. Since G(x) = 4x - 5, we can substitute 3 for x to get G(3) = 4 * 3 - 5 = 12 - 5 = 7. Therefore, g(3) = 7.

After solving the equations, the value obtained for x and y will be equal to  (-1, 1).

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given equations in the question,

y = 2x + 3     (i)

y = -x            (ii)

Substitute equation (ii) in (i)

-x = 2x + 3

-x - 2x = 3

-3x = 3

x = -3/3

x = -1

Substitute x = -1 in equation (i)

y = 2x + 3

y = 2(-1) + 3

y = -2 + 3

y = 1

The two true options are A and D

The two options that are true about the graph that represents this real-world scenario are;

All the t values must be positive, and a viable solution is (10, 50). Hence, the correct option for this question is A and D.

Plotting the data in the graph is advantageous because it gives a visual presentation of the data and makes it easy to observe and forecast the large data set in a short time.

In the case of this question, the temperature is directly reliant on the c number of cricket chirps heard in 14 seconds. Therefore, if all the c values must be positive integers, the values of t must also be positive numbers.

t = c + 40

Because 10 is a positive integer, it is a possible c value

If c = 10

t = 40 + 10

t = 50

A viable solution (10, 50) represents the values of c and t, respectively, to predict the data more accurately and with validity.

Therefore, the correct option for this question is A and D.

What is the definition of Bernoulli's principle?

In fluid dynamics, Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy.

p+12ρ v2+ρgh=konstant   Bernoulli equation(1)

Two states on a streamline are thus linked by the following equation:

p1+12ρv21+ρgh1=p2+12ρv22+ρgh2p1+12ρv21=p2+12ρv22p2=p1+12ρv21−12ρv2

Due to the constriction of the cross-section to only half the size, the flow speed is doubled. All known values can now be put in equation (5). Note that the pressure is to be used in the basic unit N/m² and the density in the unit kg/m³.

p2=p1+12ρv21−12ρv22p2=4⋅105Nm²+121000kgm³ (4ms)2–121000kgm³ (8ms)2=3.76⋅105Nm²p2=3.76 bar

The value of y in the linear equation 7x - 6y = 17 is y = -(17 + 7x)/6

Linear equations are equations of the first order. The linear equations are defined for lines in the coordinate system. When the equation has a homogeneous variable of degree 1 (i.e. only one variable), then it is known as a linear equation in one variable.

In this problem, we are to solve for y.

7x - 6y = 17

Step 1

Take 7x to the right hand side of the equation

-6y = 17 - 7x

Step 2

Divide both sides by the coefficient of y

-6y / -6 = (17 - 7x) / - 6

Step-by-step explanation:

To convert 186283 miles per second to feet per hour, we need to first convert the distance from miles to feet. There are 5280 feet in a mile, so 186283 miles is equal to 186283 * 5280 = 9,839,784,000 feet.

We also need to convert the time from seconds to hours. There are 3600 seconds in an hour, so 186283 seconds is equal to 186283 / 3600 = 51.8 hours.

Therefore, 186283 miles per second is equal to 9,839,784,000 feet per 51.8 hours, or approximately 188,822,900 feet per hour. This is the final answer.
