The limit of f(x) as x approaches 0 is 1.

The limit of f of x as x approaches 0 can be calculated using limit theorems. First, we rewrite the function as:

f(x) = (x + 1) / (1 / (x - 1))

Then, we can simplify this by multiplying both the numerator and denominator by (x - 1):

f(x) = (x + 1)(x - 1) / 1

Next, we can apply the limit theorem that states the limit of a product is the product of the limits. Thus, we can calculate the limit as:

lim f(x) = lim (x + 1)(x - 1) / 1

= lim (x + 1) * lim (x - 1) / 1

= 0 + 1 * 0 - 1 / 1

= 1 / 1

Bases and powers are employed in the exponential form to write numbers. It informs us of the amount of times we must actually multiply a number in order to obtain the answer. When we write the number 125 as 53, for instance, we can see that it is the third power of 5, or the number 125, which looks to be a typical three-digit number when observed.

When a single integer is multiplied by itself a certain number of times, x, the equation y takes on the base component b to the power of x, which is the quantity being multiplied, and is known as the exponential form.

The cylinder has a volume of 150.796 in³. The cylinder has a surface area of 175.929 in².

The quantity of three-dimensional space that an object or closed surface occupies is referred to as volume in mathematics. The cubic units of volume are m³, cm³, in³, and so on.

The sum of all of an object's faces is its surface area in three dimensions. Wrapping, painting, and finally building things to achieve the best possible design are examples of real-world applications of the concept of surface areas.

Given that a volume of cylinder = h × r² × π

                         h = 12 in

                          r = 2 in

                       volume = ?

Volume of cylinder = h × r² ×π

                                 = =12 × 3.14×(2)²

                                       =37.68 × 4

The account balance after 5 years will be $3935.53.

Compound interest is interest that is paid on both principal and interest at regular intervals. The first year of compound interest is similar to the first year of simple interest, but the difference begins in the second year.

Continuously compounded interest means that an account balance is constantly earning interest and reinvesting that interest so that it, too, earns interest.

Given that Jessica invests $3,065 in a savings account with an annual interest rate of 5% compounded continuously.

The account balance after 5 years will be calculated as:-

[tex]P(t) = P_oe^{rt}\\P(t) = 3065\times e^{0.05\times 5}\\P(t) = \$3935.53[/tex]

Step-by-step explanation:

The model that would explain the utility is U(q) = - 0.02q^2 - 300 + 10q.

The maximum number of workers is 250 and utility is 950

From the question, we have the following parameters that can be used in our computation:

The total income as I(q) = 60q - 0.02q^2.

The total cost as C(q) = 300 + 50q.

The utility model can then be calculated as

U(q) = I(q) - C(q)

So, we have

U(q) = 60q - 0.02q^2 - 300 - 50q.

U(q) = - 0.02q^2 - 300 + 10q.

We have

U(q) = - 0.02q^2 - 300 + 10q.

Differentiate and set to 0

-0.04q + 10 = 0

So, we have

-0.04q = -10

This gives

q = 250 --- max workers

Recall that

U(q) = - 0.02q^2 - 300 + 10q.

So, we have

U(250) = - 0.02* 250^2 - 300 + 10 * 250

U(250) = 950 --- amount of utility

The Mean Value Theorem states that there exists a point c in the interval of the given function such that the derivative of the function at this point is equal to the average rate of change of the function on the interval. In this case, c = 7/2 satisfies the theorem for f(x) = 3x^2 - 5x + 1 on the interval [2, 5].

Using the Mean Value Theorem, we can find c by solving the equation 3c^2 - 5c + 1 = (3(5)^2 - 5(5) + 1 - (3(2)^2 - 5(2) + 1)) / (5 - 2). Simplifying, we get c = 7/2.

The Mean Value Theorem states that there exists a point c in the interval of the given function such that the derivative of the function at this point is equal to the average rate of change of the function on the interval. To find this point c, we must solve the equation

What is inverse function?

A function that returns the initial value for which a function has produced output is called an inverse function. If f(x) is a function that produces the value y, then f-1(y), which is the inverse function of y, will produce the value x. Inverse and reciprocal functions should not be confused. The output's original value is returned by the function's inverse, represented by the symbol f-1 (x). While the reciprocal of a function is represented by 1/f(x) or f(x)-1

Those that do are referred to as invertible. For a function f: X Y to have an inverse, it must possess the characteristic that there is exactly one x in X such that f(x) = y for every y in Y. This characteristic guarantees the existence of a function g: Y X that has the required connection to f.

7:30 am. Later that day, Kim had packed exactly the same number of jars as Pat.To find the time and number of jars picked, we solve an equation.

An equation is a mathematical expression that shows the relationship between two variables.

Let

Since Pat picks at a rate of 18 jars of pickles per hour, the number of jars Pat picks is n = 18t

Also, Kim picks at a rate of 24 jars per hour, 1.5 hours later the number of jars Kim picks is n' = 24(t + 1.5)

Since n = n', we have that

18t = 24(t - 1.5)

18t = 24t - 36

18t - 24t = -36

-6t = -36

t = -36/-6

t = 6 hours

Since Kim's time is t - 1.5 = 6 - 1.5 = 4.5 hours

To find the number of jars each picked, substitute t = 6 into n. so, we have that

n = 18t

= 18(6)
