The interval [1, 2] to an absolute error less than 10⁻⁹ is 1.46826171875.We have to find the approximate value of the root of this equation in the interval [1, 2] to an absolute error less than 10⁻⁹ using the methods

We will use the Bisection Method to solve the given equation as it is a simple and robust method. The Bisection Method: The bisection method is based on the intermediate value theorem, which states that if a function ƒ(x) is continuous on a closed interval [a, b], and if ƒ(a) and ƒ(b) have different signs, then there exists a number c between a and b such that ƒ(c) = 0.

The bisection method iteratively shrinks the interval [a, b] to the desired precision until we find an approximate root of the equation. The algorithm of the bisection method is as follows Choose an interval [a, b] such that ƒ(a) and ƒ(b) have opposite signs. We will use the above algorithm to solve the given equation.

Let a = 1 and b = 2 be the initial guesses.

Then, we can check whether ƒ(a) and ƒ(b) have opposite signs:

Option (d)- No, because the events are not independent. Hence we can not conclude that because (0.26)(0.15) = 0.039 about 4% of the labor force are college-educated labors or operators.

We have given that government data show that 26% of the civilian labor force has at least 4 years of college and that 15% of the labor force works as laborers or operators of machine or vehicle.

So here,

event A = 26% of civilian labor force hast at least 4 years of college

event B = 15% of the labor force works as laborers or operators of machines or vehicles

Therefore it is observe that both the events are not independent.

Hence we cannot conclude that because (0.26)(0.15) = 0.039 about 4% of the labor force are college-educated laborers or operators.

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle.

Sin(tetha) = opp/hyp

cos( tetha) = adj/hyp

tan ( tetha) = opp/adj

therefore;

tan B = 3/5

cos B = 5/√34

sinA = 5/√34

tan A = 5/3

Since tan A = 5/3

tanA = 1.67

A = tan^-1(1.67)

A = 59°

tanB = 3/5

B = tan^-1( 0.6)

B = 31°

Step-by-step explanation: Yes, but ONLY when you are multiplying or dividing.

Answer:

The answer should be B

If Martina has 16 cars available to rent, and if c is the number of cars she would have left after renting r of them, then the equation relating c to r will be c = 16 - r, and the number of cars she would have been left with after renting 14 of them is calculated to be 2.

An algebraic expression is a type of expression consisting of both numerals and letters.

If Martina has a total of 16 cars available to rent, then the equation or algebraic expression relating c to r is,

c = total number of cars available to rent - r

c = 16 - r

After renting 14 of the total cars available, then the number of cars left can be calculated using this equation,

c = 16 - r

c = 16 - 14

c = 2

Thus, the number of cars she would have been left with is calculated to be 2.

Answer:

A = 0.1m

A = $6.5

Step-by-step explanation:

We are told that each minute of use costs $0.10.

If the minutes spent is represented by "m" and amount spent is "A', then the relation for amount spent is;

A = 0.1m

If he talked for 65 minutes, then we have;

A = 0.1 × 65

A = $6.5

To find the radius of convergence, we can use the ratio test. The ratio test states that if the limit of the absolute value of the ratio of consecutive terms of a series is L, then the series converges if L < 1 and diverges if L > 1.

The given series is:

∑ [(6 · 13 · 20 · ⋯ · (7n − 1)) / n!] * xn     (n starts from 1)

Using the ratio test, we take the absolute value of the ratio of the (n+1)th term to the nth term:

|(6 · 13 · 20 · ⋯ · (7(n+1) − 1)) / (n+1)! * x^(n+1)| / |(6 · 13 · 20 · ⋯ · (7n − 1)) / n! * xn|

Simplifying, we get:

|[(7n + 6) / (n+1)] * x| / |(7n − 1)|

Now, we take the limit as n approaches infinity:

lim(n→∞) |[(7n + 6) / (n+1)] * x| / |(7n − 1)|

Using the limit properties, we can simplify this expression further:

lim(n→∞) |(7 + 6/n) * x| / 7

Since the series involves x^n, we want the limit to be in terms of x. Therefore, we take the absolute value of x out of the limit:

|x| * lim(n→∞) |(7 + 6/n)| / 7

The term lim(n→∞) |(7 + 6/n)| / 7 is equal to 1, so we have:

|x| * 1

Therefore, the limit expression simplifies to:

|r|

Now, we know that for the series to converge, the absolute value of r must be less than 1. Thus, we have:

|r| < 1

This means that the radius of convergence is 1. Now, to find the interval of convergence, we need to check the endpoints of the interval.

When |x| = 1, the series becomes:

∑ [(6 · 13 · 20 · ⋯ · (7n − 1)) / n!] * x^n

Since the ratio test is inconclusive at the endpoints, we need to check for convergence or divergence separately.

For x = 1, the series becomes:

∑ [(6 · 13 · 20 · ⋯ · (7n − 1)) / n!]

This series is known as the "alternating harmonic series" and is convergent.

For x = -1, the series becomes:

∑ [(-1)^n * (6 · 13 · 20 · ⋯ · (7n − 1)) / n!]

This series also converges.

Therefore, the interval of convergence is -1 ≤ x ≤ 1.

In summary:

Radius of convergence (r) = 1

Interval of convergence (i) = -1 ≤ x ≤ 1

To develop an expression to substitute for [ei] in equation 2, we'll start with the definition of i (the d for binding of i to e). Let's assume the equation 2 is as follows: Equation 2: A + B = [ei] + C

To substitute [ei] in equation 2, we need to express it in terms of the definition of i and e. Let's say the definition of i (the d for binding of i to e) is given by:

Definition of i: i = f(e)

Now, we can substitute [ei] in equation 2 using the definition of i:

Equation 2 (substituting [ei]): A + B = f(e) + C

This expression replaces [ei] in equation 2 with the function f(e), which represents the binding of i to e according to the given definition.

It is also given that 60 households use only Brand A and that three times as many households use Brand B exclusively as use both brands.

If x is the number of households that use both Brand A and Brand B, then 3x use Brand B alone.

To find the area of the surface obtained by rotating the curve y = 4x^3 from x = 0 to x = 2 about the x-axis, we can use the formula for surface area of revolution. The formula is given by:

A = 2π∫[a,b] f(x)√(1 + (f'(x))^2) dx

In this case, f(x) = 4x^3, so f'(x) = 12x^2. Plugging these values into the formula, we get:

A = 2π∫[0,2] 4x^3√(1 + (12x^2)^2) dx

Simplifying the expression inside the square root, we have:

A = 2π∫[0,2] 4x^3√(1 + 144x^4) dx

Integrating this expression is a complex task, and it cannot be simplified into a single formula. However, it can be numerically approximated using numerical integration methods such as Simpson's rule or numerical software. The resulting value will be the area of the surface obtained by rotating the curve about the x-axis.

Similarly, to find the surface area of revolution about the x-axis of y = 4sin(2x) over the interval 0 ≤ x ≤ π/2, we can use the same formula and follow a similar process of integration. However, the expression inside the square root will be different since f(x) = 4sin(2x), and we need to evaluate the integral over the specified interval. Again, numerical methods can be used to approximate the value of the surface area.

Answer:

We can not see the image, so i will answer this in a general way.

We know that a linear equation can be written as:

y = a*x + b

Where a is the slope, and b is the y-intercept.

In this case, we know that this line has a slope equal to -2, then the line is:

y = -2*x + b

Now, suppose that in the image we can see that this line passes through the point (j, k)

Then we can replace x by j, and y by k in the line equation, to get:

k = -2*j + b

Now we can solve this for b:

b = k + 2*j

Then we can conclude that a line with a slope equal to -2, that passes through the point (j, k) is:

y = -2*x + (k + 2*j)

The indefinite integral of eu(2 − eu)² du is 2u² - 4u³/3 + u⁴/4 + C

To evaluate the indefinite integral of eu(2 − eu)² du, we can use substitution. Let's make the substitution v = eu, then dv = e du:

∫ (eu(2 − eu)²) du

Let v = eu, then dv = e du

∫ (v(2 - v)²) (1/e) dv

∫ (v(2 - v)²) / e dv

Expanding the expression inside the integral:

∫ (v(4 - 4v + v²)) / e dv

∫ (4v - 4v² + v³) / e dv

Now we can integrate each term separately:

∫ (4v - 4v² + v³) / e dv

= ∫ (4v/e - 4v²/e + v³/e) dv

= (4/e) ∫ v dv - (4/e) ∫ v² dv + (1/e) ∫ v³ dv

Integrating each term:

= (4/e) * (v²/2) - (4/e) * (v³/3) + (1/e) * (v⁴/4) + C

Substituting back v = eu:

= (4/e) * (eu)²/2 - (4/e) * (eu)³/3 + (1/e) * (eu)⁴/4 + C

= 2eu²/e - 4eu³/3e + eu⁴/4e + C

Simplifying further:

= 2u² - 4u³/3 + u⁴/4 + C

Therefore, the indefinite integral of eu(2 − eu)² du is 2u² - 4u³/3 + u⁴/4 + C, where C is the constant of integration.
