For f(x)=2/√10-6
Evaluate f (-6) = ?

Combining the given information, ∫51′() = f(5) - f(1) = -7 - (-2) = -5. , the integral of ∫51′() is equal to -5.

In order to evaluate the integral ∫51′(), we need to use the Fundamental Theorem of Calculus. The Fundamental Theorem of Calculus states that the integral of a function's derivative is equal to the function value evaluated from one point to another. For example, if f'(x) is the derivative of a function f(x), then the integral of f'(x) from x = a to x = b is equal to f(b) - f(a).

Using the given information, we can solve the integral ∫51′() as follows. We know that the derivative of our function is 1, so the integral of 1 from x = 1 to x = 5 is equal to f(5) - f(1). Therefore, combining the given information, ∫51′() = f(5) - f(1) = -7 - (-2) = -5. Therefore, the integral of ∫51′() is equal to -5.

This is a pond in the shape of a prism. It is completely full of water. Colin has to wait for the pond to completely empty is 2hrs and 30minutes.

We have a pond which is completely filled with the water.

Area of the side face ( trapezium shaped)

= 1/2 x (1.4 + 0.6) x 2

= 2 m²

Volume = area x height (here width)

V = 2x1 = 2 m³

The level goes down by 20cm in the first 30 mins

Volume of water that will be taken down =

=0.2 x 1 x 2

=0.4 m³ ( upper water will form cuboid face)

Now,

⇒0.4 m³ water is taken out in 30 minutes

⇒1 m³ water is taken out in 30/0.4 minutes

⇒2 m³ water is taken out in 30/0.4 x 2 minutes

The equation of the exponential model is f(x) = 3 * 0.2^x

The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = bx is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.

Given a data set:

x                                        f(x)

−2                                      71

−1                                       13

 0                                       3

 1                                      0.6

 2                                     0.1

An exponential model is represented as:

f(x) = ab^x

When x= 0 and f(x) = 3;

We have:

ab^0 = 3

This gives

a = 3

When x= 1 and f(x) = 0.6

We have:

ab^1 = 0.6

This gives

ab = 0.6

Substitute 3 for a

3b = 0.6

Divide both sides by 3

b = 0.2

Substitute b = 0.2 and a =3 in f(x) = ab^x

f(x) = 3 * 0.2^x

Hence, the equation of the exponential model is f(x) = 3 * 0.2^x

The vertical asymptote is x = 1 or 7

There is no horizontal asymptote

An asymptote is a straight line that constantly approaches a given curve but does not meet at any infinite distance. In other words, Asymptote is a line that a curve approaches as it moves towards infinity.

To find vertical asymptote we set the denominator to 0 and we find the value of x

:. x² - 8x +7 = 0

x² -7x-x+7 = 0

(x²-7)(-x+7) = 0

x( x-7) -1(x-7) = 0

The height of the box in feet is 6 feet.

The surface area of a rectangular prism is the overall region or area that is covered by all of its faces. A three-dimensional shape is a rectangular prism. It has six faces, each of which is rectangular in shape. Consequently, a rectangular prism's two bases must likewise be rectangles.

The surface area of the rectangular prism is given by the formula:

A = 2(wl + hl + hw)

Substitute the value of A = 148, l = 4 and w = 5:

148 = 2((5)(4) + (4)h + (5)h)

148 = 40 + 8h + 10h

In other words, if you have two parallel lines and a transversal intersecting them, and you draw a line segment connecting two nonadjacent interior angles on opposite sides of the transversal, then those two angles will be congruent.

In mathematical terms, if X is the sum of successes in n different Bernoulli trials, and p is the likelihood of success in each trial, then X may be represented as a normal distribution with mean increasing as n rises.

μ = np

variance σ^2 = np(1-p)

The binomial distribution is a discrete probability distribution that produces just two outcomes in an experiment: success or failure. In a binomial distribution, the chance of success must remain constant during the trials under consideration. For example, because there are only two possible outcomes when tossing a coin, the chance of flipping a coin is 1/2 or 0.5 for each experiment we do.

Here,

When the sample size (n) is high, the distribution of the total of successes (k) in n separate Bernoulli trials approaches a normal distribution, according to the normal approximation for the binomial distribution.

In mathematical terms, if X is the total of successes in n separate Bernoulli trials, with p being the chance of success in each trial, then X may be represented by a normal distribution with mean as n increases.

The loan will be (ln(Time) - ln(136,000) + ln(1,180)) / ln(1 + 6.5 / 12) repaid.

What is interest ?

Interest is payment from a borrower or deposit-taking financial institution to a lender or depositor of an amount above repayment of the principal sum, at a particular rate.

Time = Loan Amount * (1 + Interest Rate / 12)^(12 * Number of Payments) / Monthly Payment

Given the loan amount ($136,000), interest rate (6.5%), and monthly payment ($1,180), we can plug these values into the formula:

Time = 136,000 * (1 + 6.5 / 12)^(12 * Number of Payments) / 1,180

To find the number of payments, we need to take the natural logarithm of both sides:

ln(Time) = ln(136,000 * (1 + 6.5 / 12)^(12 * Number of Payments) / 1,180)

ln(Time) = ln(136,000) + ln((1 + 6.5 / 12)^(12 * Number ofPayments)) - ln(1,180)

ln(Time) = ln(136,000) + 12 * Number of Payments * ln(1 + 6.5 / 12) - ln(1,180)

Next, we can isolate the number of payments on one side:

12 * Number ofPayments * ln(1 + 6.5 / 12) = ln(Time) - ln(136,000) + ln(1,180)

The loan will be (ln(Time) - ln(136,000) + ln(1,180)) / ln(1 + 6.5 / 12) repaid.

c = log_10(25) is the value of c that makes y(1) = 5.

What is differential ?

A differential is a gear train with three drive shafts that has the property that the rotational speed of one shaft is the average of the speeds of the others, or a fixed multiple of that average.

y'(x) = c * x^(c-1) * x^(-2) + (-2) * x^c * x^(-2) = (c - 2) * x^(c-3)

Now, we can substitute y(x) and y'(x) into the differential equation:

xy' + 2y = 3x

x * (c - 2) * x^(c-3) + 2 * x^c * x^(-2) = 3x

(c - 2) * x^(c) + 2 * x^c * x^(-2) = 3x

(c - 2) * x^c + 2 * x^(-2) = 3x

This confirms that y(x) = x^c * x^(-2) is indeed a solution of the differential equation xy' + 2y = 3x.

To find the value of c so that y(1) = 5, we need to substitute x = 1 and y = 5 into the solution y(x) = x^c * x^(-2):

y(1) = 1^c * 1^(-2) = 5

1^c = 5 * 1^2 = 25

c = log_1(25)

c = log_10(25) / log_10(1) = log_10(25)

What is the identity of the sum of cubes?

What Does the Algebraic Sum of Cubes Formula Mean? One of the key algebraic identities is the sum of cubes formula. Its symbol is written as a3 + b3 and is interpreted as a cube plus a cube. A3 + b3 = (a + b) (a2 - ab + b2) is how the sum of cubes formula (a3 + b3) is written.

The variance of X is (C) 35/12.

The formula for variance of a discrete random variable X is:

Var(X) = E[(X - E[X])^2] = E[X^2] - (E[X])^2

where E[X] represents the expected value of X.

To calculate the variance, we first need to find the expected value of X, which is:

E[X] = (1 + 2 + 3 + 4 + 5 + 6) / 6 = 3.5

Next, we find the expected value of X^2:

E[X^2] = (1^2 + 2^2 + 3^2 + 4^2 + 5^2 + 6^2) / 6 = 91/6

Now we can substitute the values into the variance formula:
