The value of given function [tex]\int\limits^1_{-1}[/tex]f(x)dx is equal is 5/6. So, correct option is A.

To find the integral of f(x) from -1 to 1, we need to split the interval [-1,1] into three parts, where f(x) is defined differently.

For x < 0, f(x) = x², so the integral of f(x) from -1 to 0 is:

[tex]\int\limits^0_{-1}[/tex](x²)dx = (-1/3)x³ evaluated at x=0 and x=-1 = (-1/3)(0 - (-1)) = 1/3

For x = 0, f(x) = -1, so the integral of f(x) at x=0 is simply -1.

For x > 0, f(x) = x, so the integral of f(x) from 0 to 1 is:

[tex]\int\limits^1_{0}[/tex](x)dx = (1/2)x² evaluated at x=1 and x=0 = (1/2)(1 - 0)² = 1/2

Therefore, the integral of f(x) from -1 to 1 is:

[tex]\int\limits^1_{-1}[/tex]f(x)dx = [tex]\int\limits^0_{-1}[/tex](x²)dx  + [tex]\int\limits^0_{0}[/tex](-1)dx + [tex]\int\limits^1_{0}[/tex](x)dx

= 1/3 + (-1) + 1/2

= 5/6

Thus, the correct answer is (a) 5/6.

So, correct option is A.

Numerator: e^(1 + ln ∞) * (1/∞) = e^(1 + ∞) * 0 = 0, Denominator: 1 + e^∞ = ∞. So, the limit of the expression is: lim (x→∞) [e^(1 + ln x) / ln (1 + e^x)] = 0/∞ = 0

To find the limit of the given function, let's first rewrite the terms using the provided limit notation:

lim (x→∞) [e^(1 + ln x) / ln (1 + e^x)]

To solve this limit, we will apply L'Hôpital's rule, which states that if the limit has the form 0/0 or ∞/∞, we can find the limit by taking the derivative of the numerator and denominator with respect to x:

Numerator: d(e^(1 + ln x))/dx = e^(1 + ln x) * d(1 + ln x)/dx = e^(1 + ln x) * (1/x)
Denominator: d(ln(1 + e^x))/dx = (1/(1 + e^x)) * d(e^x)/dx = (1/(1 + e^x)) * e^x

Now, we will find the limit of the new expression:

lim (x→∞) [(e^(1 + ln x) * (1/x)) / ((1/(1 + e^x)) * e^x)]

Simplify the expression by canceling out the e^x terms:

lim (x→∞) [(e^(1 + ln x) * (1/x)) / (1 + e^x)]

Now, let's substitute x→∞:

Numerator: e^(1 + ln ∞) * (1/∞) = e^(1 + ∞) * 0 = 0
Denominator: 1 + e^∞ = ∞

So, the limit of the expression is:

lim (x→∞) [e^(1 + ln x) / ln (1 + e^x)] = 0/∞ = 0

Step-by-step explanation:

The bumblebee flutters its wings more times in 1 minute, as it flutters its wings 7,800 times in one minute, whereas the hummingbird flaps its wings 80 times in one second, which translates to 4,800 times in one minute.

To understand this calculation in more detail, we can use unit conversions and multiplication. Since the hummingbird's wing flaps are given in seconds and the bumblebee's wing flutters are given in minutes,

we convert the hummingbird's wing flaps from seconds to minutes by multiplying by 60. We then compare the total number of wing flaps for each animal and find that the bumblebee flutters its wings more times in one minute than the hummingbird flaps its wings.

This is due to the bumblebee's higher frequency of wing movement, which enables it to achieve more wing flutters in a given amount of time.

Recall 5%=.05 as a decimal. Then multiply 140(.05)=7 to get how many centimeters he grew. Add 140+7=147 to get his current height.

The 95% confidence interval for the U.S. Cesarean delivery rate for this year is approximately (0.3314, 0.4886) or 33.14% to 48.86%.

To estimate the U.S. Cesarean delivery rate for this year with 95% confidence using the provided information, we can construct a confidence interval for the population proportion.

Given:

Population proportion estimates from the NVS Report for 2011: p = 0.328 (32.8%)

Sample size: n = 100

Number of C-sections in the sample: x = 41

First, we need to check if a normal model is appropriate for the sample proportion. For this, we can verify if the sample size is sufficiently large and if both np and n(1-p) are greater than 10.

np = 100 * 0.328 = 32.8

n(1-p) = 100 * (1 - 0.328) ≈ 67.2

Since both np and n(1-p) are greater than 10, we can assume that the conditions for a normal model are met.

Now, we can calculate the confidence interval using the sample proportion and the critical value corresponding to a 95% confidence level.

Sample proportion (p-hat) = [tex]\frac{x }{ n}[/tex] =[tex]\frac{ 41 }{ 100 }[/tex]= 0.41

The critical value for a 95% confidence level can be obtained from a standard normal distribution or a Z-table. In this case, the critical value is approximately 1.96.

The margin of error (E) can be calculated as:

E = Z * [tex]\sqrt((\frac{p-hat * (1 - p-hat))} { n})[/tex]

E = 1.96 * [tex]\sqrt((\frac{0.41 * (1 - 0.41))}{ 100)}[/tex]

E ≈ 0.0786

Finally, we can construct the confidence interval by subtracting and adding the margin of error from the sample proportion.

Confidence interval = p-hat ± E

Confidence interval = 0.41 ± 0.0786

Therefore, the 95% confidence interval for the U.S. Cesarean delivery rate for this year is approximately (0.3314, 0.4886) or 33.14% to 48.86%.

Note: It's important to consider that this calculation assumes the sample is representative of the U.S. population and that the conditions for a normal model are satisfied. Additionally, the estimate from the NVS Report for 2011 is used as the population proportion.

To find the volume and surface area of the composite figure, we need to find the volume and surface area of the right cylinder and the hemisphere separately, and then add them together.

First, let's find the volume of the right cylinder.

The formula for the volume of a right cylinder is V = πr^2h, where r is the radius and h is the height. In this case, the radius is half of the diameter, which is 4/2 = 2 inches. So, the volume of the right cylinder is:

V1 = π(2)^2(12) = 96π cubic inches

Next, let's find the volume of the hemisphere. The formula for the volume of a hemisphere is V = (2/3)πr^3, where r is the radius. In this case, the radius is also 2 inches. So, the volume of the hemisphere is:

V2 = (2/3)π(2)^3 = 16/3π cubic inches

To find the total volume of the composite figure, we just need to add V1 and V2:

Vtotal = V1 + V2 = 96π + 16/3π = 320/3π cubic inches

Now, let's find the surface area of the composite figure.

To do this, we need to find the surface area of the curved surface of the cylinder, the top of the cylinder, and the curved surface of the hemisphere separately, and then add them together.

The formula for the surface area of the curved surface of a cylinder is A = 2πrh, where r is the radius and h is the height. In this case, the radius is still 2 inches, and the height is 12 inches. So, the surface area of the curved surface of the cylinder is:

A1 = 2π(2)(12) = 48π square inches

The formula for the surface area of the top of a cylinder is A = πr^2, where r is the radius. In this case, the radius is still 2 inches. So, the surface area of the top of the cylinder is:

A2 = π(2)^2 = 4π square inches

Finally, the formula for the surface area of the curved surface of a hemisphere is A = 2πr^2, where r is the radius. In this case, the radius is still 2 inches. So, the surface area of the curved surface of the hemisphere is:

A3 = 2π(2)^2 = 8π square inches

To find the total surface area of the composite figure, we just need to add A1, A2, and A3:

Atotal = A1 + A2 + A3 = 48π + 4π + 8π = 60π square inches

So, the volume of the composite figure is 320/3π cubic inches, and the surface area of the composite figure is 60π

To determine the size of the tablecloth needed to cover a square tabletop with a perimeter of 20 feet, we will first find the side length of the square and then calculate the area.

Step 1: Determine the side length of the square.
Since the perimeter of a square is equal to 4 times its side length (P = 4s), we can find the side length by dividing the perimeter by 4.
Side length (s) = Perimeter (P) / 4 = 20 ft / 4 = 5 ft
