To find the volume of water flowing out of the pipe every second, we first need to find the cross-sectional area of the pipe. The formula for the area of a circle is π * r^2, where r is the radius. So, the radius of the pipe is 8/2 = 4 inches.

The cross-sectional area of the pipe is π * 4^2 = 16π square inches.

Now, since the water is flowing at a rate of 2 feet per second, and 1 foot is equal to 12 inches, the flow rate in inches per second is 2 * 12 = 24 cubic inches per second.

So, the exact volume of water flowing out of the pipe every second is the cross-sectional area of the pipe times the flow rate:

16π * 24 = 384π cubic inches per second.

The Values for rectangle type wall and circle will be gallons of paint that are required to paint one side of a block wall =5.16 gallon, the gallons of sealer required to seal a floor=4.22 gallon and circumference of circle≈39 feet.

What exactly is a rectangle?

Rectangles are four-sided polygons with all internal angles equal to 90 degrees. At each corner or vertex, two sides meet at right angles. The rectangle differs from a square in that its opposite sides are equal in length.

For example, if one side of a rectangle is 20 cm long, the opposing side is similarly 20 cm long.

A rectangle has two diagonals that intersect. Both diagonals are the same length

P = 2 (Length + Width) is the perimeter.

Rectangle Area=Length*Breadth

Answer:

The rate at which the turtle is crawling can be found by dividing the distance traveled in miles by the time in hours.

So, the turtle can travel 3/20 of a mile in 5/6 of an hour, which means that the turtle is crawling at a rate of (3/20) / (5/6) miles per hour.

To simplify, we need to convert both the numerator and denominator to a common unit. If we multiply the numerator and denominator by 6, we get:

(3/20) * 6 / (5/6) * 6 = 3 / 5 miles per hour.

Therefore, the turtle is crawling at a rate of 3/5 miles per hour.

The formula to calculate the future value of an investment with compound interest is:

FV = PV * (1 + (r/n))^(n*t)

Where:

PV is the present value (the initial investment)

r is the annual interest rate

n is the number of compounding periods per year

t is the number of years

For Investment A:

PV = $4,000

r = 6% = 0.06

n = 2 (semiannual compounding)

t = 5 years

FV = $4,000 * (1 + (0.06/2))^(2*5) = $4,000 * (1.03)^10

FV = $4,000 * 1.664131669 = $6,656.53

So, the total amount of Investment A is $6,656.53 (rounded to the nearest cent).

The spherical coordinates of the given rectangular coordinates are (10, 0, 60).

The cartesian coordinate or rectangular coordinates describes the location of a point in space using an ordered triple where each coordinate represents a distance. The spherical coordinate system describes the location of a point in space using an ordered triple where coordinate describes one distance and two angles. In the spherical coordinate system, a point is represented by the ordered triple (ρ, θ, φ).

The equations which are used to convert from rectangular coordinates to spherical coordinates are:

ρ^2=x^2+y^2+z^2

tan⁡〖θ= y/x〗

φ=arccos⁡〖z/√(x^2+y^2+z^2 )〗

The given rectangular coordinates are (5√3, 0, 5). Hence,

The probability of getting at least 1 red is 6/7

Probability is the likelihood of a desired event happening.

Theoretical probability is the theory behind probability. To find the probability of an event, an experiment is not required. Instead, we should know about the situation to find the probability of an event occurring.

The probability that the first is blue and the second is blue

p(First blue, Second blue) = 3/7 × 2/6 = 1/7

Thus, the probability of getting at least 1 red, is the complement of getting both blue

That is, P(At least 1 red) = P'(both blue) = 1 - P(Both blue) = 1 - 1/7 = 6/7

Answer:

1st question:

10°, 80°, 90°

2nd question:

76°, 52°, 52°

Step-by-step explanation:

For both of these questions we will use the idea that the three angles of a triangle add up to 180°.

In the triangle on the left, two angles are marked and the third is a right angle. The tiny square marking on the third angle means it is a right angle, so it is 90°.

We can write an equation.

x + 8x + 90° = 180°

combine like terms

9x + 90 = 180

subtract 90

9x = 90

divide by 9

x = 10

So the angles are x, 8x and 90°

Since x = 10

the 3 angles are 10°, 80° and 90°

For the second question, two sides are marked to show they are congruent (same, equal) that means the two angles on the base (base angles) are congruent (the same)

One angle is 3x+1 and both the other two angles are 2x+2. Write an equation.

3x+1 + 2x+2 + 2x+2 = 180°

combine like terms

7x + 5 = 180

subtract 5

7x = 175

divide by 7

x = 25

Calculate the angle measures using x = 25

3x+1 = 3(25)+1 = 76°

2x+2 = 2(25)+2 = 52°

The 3 angles of the triangle are 76°, 52° and 52°

We have the differential equation, [tex]y''+5y'+4y=2e^{-2x}[/tex]. The question asks to find the particular solution to the DE.

To find the particular solution look at the right-hand-side and make a “guess” of what the solution could be.

Since we have [tex]2e^{-2x}[/tex] we can guess that the particular solution could be in the form [tex]Ae^{-2x}[/tex], where [tex]A[/tex] is some unknown constant.

Now finding the value of the unknown constant, [tex]A[/tex]. Lets say [tex]g(x)=Ae^{-2x}[/tex], find [tex]g'(x)[/tex] and [tex]g''(x)[/tex].

[tex]g(x)=Ae^{-2x}[/tex]

=> [tex]g'(x)=-2Ae^{-2x}[/tex]

=> [tex]g''(x)=4Ae^{-2x}[/tex]

Now plug [tex]g(x)[/tex], [tex]g'(x)\\[/tex], and [tex]g''(x)[/tex] into the given differential equation.

=> [tex]y''+5y'+4y=2e^{-2x}[/tex]

=> [tex](4Ae^{-2x})+5(-2Ae^{-2x})+4(Ae^{-2x})=2e^{-2x}[/tex]

=> [tex]4Ae^{-2x}-10Ae^{-2x}+4Ae^{-2x}=2e^{-2x}[/tex]

=> [tex]8Ae^{-2x}-10Ae^{-2x}=2e^{-2x}[/tex]

=> [tex]-2Ae^{-2x}=2e^{-2x}[/tex]

Compare the coefficients,

=>[tex]-2A=2[/tex]

=>[tex]A=-1[/tex]

So we can say our "guess" to the particular solution of the given differential equation is, [tex]y_{p} =-e^{-2x}[/tex].

Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.

Here, a is called the numerator and b is called the denominator.

Given expression is [tex]\frac{8a + 4b}{2ab+b^2-2ad-bd}[/tex].

We have to simplify each of the numerator and denominator in the expression [tex]\frac{8a + 4b}{2ab+b^2-2ad-bd}[/tex].

Take the common factor in each of the expressions in numerator and denominator.

8a + 4b = 4(2a + b)

2ab + b² - 2ad - bd = 2ab - 2ad + b² - bd

                               = 2a(b - d) + b(b - d)

                               = (b - d) (2a + b)

[tex]\frac{8a + 4b}{2ab+b^2-2ad-bd}[/tex] = [tex]\frac{4(2a+b)}{(b-d)(2a+b)}[/tex]

The curve of intersection of the two surfaces is given by the set of points in 3D space that are simultaneously on the cylinder and on the surface z = xy. This means that for any point on the curve of intersection, the distance from the origin to the point must be equal to 5, and the height of the point must be equal to its x-y coordinate.

We can find a vector function that represents the curve of intersection by parameterising the points on the curve in terms of a scalar parameter t. For example, a possible parameterization of the curve of intersection is:

r(t) = (5 cos(t), 5 sin(t), 5 cos(t) sin(t))

where t is a scalar parameter that ranges over all values between 0 and 2π. The values of x, y, and z are given by 5 cos(t), 5 sin(t), and 5 cos(t) sin(t), respectively, and represent a point on the curve of intersection for each value of t.

The smallest integer a such that the intermediate value theorem guarantees that f(x) has a zero on the interval [0, a] is 2.

The intermediate value theorem states that if a function f is continuous on the closed interval [a, b] and if y is a value between f(a) and f(b), then there exists a point c in the interval [a, b] such that f(c) = y.

In this case, we want to find the smallest integer a such that f(x) has a zero on the interval [0, a]. Since f(0) = 7 and f(x) = -2x^3 + 8x^2 - 6x + 7, we need to find the smallest a such that f(a) < 0.

We can start by finding the values of x where f(x) changes sign. To do this, we can set f(x) equal to 0 and solve for x:

-2x^3 + 8x^2 - 6x + 7 = 0

This is a cubic equation and can be solved using various methods such as factoring, substitution, or the use of a numerical method. However, since we are looking for the smallest integer a, we can use an estimation method such as the Newton-Raphson method to approximate the smallest positive root of the equation.

A common initial guess for the smallest positive root of a cubic equation is x = 1. Using this as the initial guess, we can iterate using the following formula:

x_{n+1} = x_n - f(x_n)/f'(x_n)

where f'(x) is the derivative of f(x) and x_n is the nth estimate of the root.

After several iterations, the estimate for the smallest positive root of the equation can be found to be approximately 1.56. Therefore, the smallest integer a such that the intermediate value theorem guarantees that f(x) has a zero on the interval [0, a] is 2.
