One of the most fundamental curved geometric forms is the cylinder, which is often a three-dimensional solid. It is referred to as a prism with a circle as its base in elementary geometry. Several contemporary fields of geometry and topology also define a cylinder as an indefinitely curved surface. A three-dimensional object known as a "cylinder" consists of curving surfaces with circular tops and bottoms. A cylinder is a three-dimensional solid figure that has two bases that are both identical circles joined by a curving surface at the height of the cylinder, which is determined by the distance between the bases from the center. Examples of cylinders are cold beverage cans and toilet paper wicks.

From your selections of answers, It's B: 12 x^3 - 21 b^5, but it's not completely simplified.

Step-by-step explanation:

Simplify the following:

3 (3 x^3 - 7 b^5) + 3 x^3

3 (3 x^3 - 7 b^5) = 9 x^3 - 21 b^5:

3 x^3 + (9 x^3 - 21 b^5)

Grouping like terms, 9 x^3 + 3 x^3 - 21 b^5 = (3 x^3 + 9 x^3) - 21 b^5:

(3 x^3 + 9 x^3) - 21 b^5

3 x^3 + 9 x^3 = 12 x^3:

12 x^3 - 21 b^5

Factor 3 out of 12 x^3 - 21 b^5:

Answer:  (3 (4 x^3 - 7 b^5)) = 12 x^3 - 21 b^5

What is Arithmetic progression?

Arithmetic progression can be defined as the sequence of numbers in which the difference between any consecutive numbers is same.

Given ,

To evaluate arithmetic series.

Given ,

a20 = -3803

and d = -20

an = 197 - 200n

a20 = a+(20-1)d

a20 = a+ 19d

Answer:

Step-by-step explanation:

Oof, this question is long.

Alr,

1.

a) Time = Distance/ speed = 384000/299792.458 = 1.28 seconds

b) Time = Distance/speed = 149600000/299792.458 = 499.0 or 8.317 minutes.

2.

If the distance 4.37 light years, if we travel at the speed of light, we can reach there in 4.37 years.

so, Speed = Distance/time

Speed = 4.37 light years/100 years

Speed = 0.0437 light year/year

So, the speed would be 0.0437 x speed of light. or 13100 or 1.31 x 10⁴.

Answer:

Step-by-step explanation:

We may use the chain rule to find the derivative of f(x) = (5 + e2x). The chain rule asserts that if y = f(u) and u = g(x), then the derivative of y with respect to x is:

dy/dx = dy/du * du/dx

In this situation, let u = 5 + e2x, and we get:

f(u) = √u

And we know that the derivative of u with regard to u is:

df(u)/du = 1/(2*u)

We also know:

du/dx = 2e2x

So, when we plug these into the chain rule, we get:

df(x)/dx = du/dx = 1/(2*u) * 2e2x = e2x/((5 + e2x))

As a result, the derivative of f(x) = (5 + e2x) is:

f'(x) = e2x / (5 + e2x)

The formula for the surface area of a rectangular prism is SA = 2(lw) + 2(wh) + 2(lh), where l is the length, w is the width, and h is the height.

Given:

l = 2.8 yards

w = 1.19 yards

h = 6 yards

Plugging in the values:

SA = 2(2.8 * 1.19) + 2(1.19 * 6) + 2(2.8 * 6)

Simplifying and converting units to square yards:

SA = 2(3.32) + 2(7.14) + 2(16.8)

SA = 6.64 + 14.28 + 33.6

SA = 54.52 square yards.

To calculate the number of revolutions per minute (RPM) that the wheels of the truck make, we can use the formula:

RPM = (Speed in miles per hour) / (Wheel circumference in inches) x (12 inches/foot) x (1 minute/60 seconds) x (1 foot/5280 miles)

The wheel circumference can be calculated by using the formula C = 2πr, where C is the circumference, π is pi (approximately 3.14), and r is the radius of the wheel (half the diameter).

So first we need to find the radius of the wheel:

r = 22 inches / 2 = 11 inches

Now we can calculate the wheel circumference:

C = 2πr = 2 * 3.14 * 11 inches = 69.96 inches

Now we can calculate the RPM:

RPM = (55 mph) / (69.96 inches) x (12 inches/foot) x (1 minute/60 seconds) x (1 foot/5280 miles)

RPM = 814.85

The wheels of the truck make approximately 814.85 revolutions per minute.

To calculate the angular speed of the wheels in radians per minute, we can use the formula:

ω = (RPM x 2π) / 60

ω = (814.85 x 2π) / 60 = 51.64 rad/min

The angular speed of the wheels is 51.64 radians per minute.

The graph of g is B. This is because the function f(x) is shifted right by 2 units and down by 4 units, which is represented by the graph in B.

Step-by-step explanation:

The graph for function g is attached below.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

The parent function is

f(x) = ∛x

This function is transformed to obtain

g(x) = ∛(x + 2) - 4.

So, +2 is a horizontal translation, that shifts the graph of the parent function to the left by 2 units.

Integers are present in the places of ones, tens, hundreds, thousands, and ten thousand in these numbers. Any positive number may be placed at these places, with the exception of 0 at the ten thousand places.

A general 5-digit number can be written as:

a×10000 + b×1000 + c×100 + d×10 + e where a, b, c, and d are single-digit numbers.

a is the ten thousand digit

b is the thousands digit

c is the hundreds digit

d is the tens digit

e is the unit digit.

Let 8 be at one's place that is e

Now, it is given that 8 is in a place that is 10 times less than the place of 4.

This implies 4 is at the ten's place that is d.

Next, it is given that 3 is in a place that is 100 times greater than the place of 4.

That is 100×10 = 1000 place

So, 3 is at the place of b.

The 2 is in a place that is 10 times less than the place of the 3. So, 2 is at the place of c.

The 7 is in a place that is 100 times greater than the 2. That is 100×100 = 10,000 places.

Thus, 7 is at the place of a.

Thus, we obtain

a= 7

b= 3

c= 2

d= 4
