The value of the volume of Sphere A is expressed as: 128π

The formula to calculate the volume of a sphere is given as:

V = ⁴/₃πr³

Where:

V is volume

r is radius

The radius of sphere A is: r_A = 2r_b

Radius of Sphere B is: r_B

Volume of sphere B = 16π

Thus:

⁴/₃πr_B³ = 16π

r_B³ = 12

r_b = ∛12

V_A = ⁴/₃π(2 * ∛12)³

V_A = ⁴/₃π * 8 * 12

= 128π

Step-by-step explanation:

To solve the equation |5-4r| = 17, we need to consider two cases:Case 1: 5 - 4r is positiveIf 5 - 4r is positive, then we have:5 - 4r = 17Subtracting 5 from both sides, we get:-4r = 12Dividing both sides by -4, we get:r = -3So if 5 - 4r is positive, then the solution to the equation is r = -3.Case 2: 5 - 4r is negativeIf 5 - 4r is negative, then we have:-(5 - 4r) = 17Simplifying the left side by distributing the negative sign, we get:-5 + 4r = 17Adding 5 to both sides, we get:4r = 22Dividing both sides by 4, we get:r = 5.5So if 5 - 4r is negative, then the solution to the equation is r = 5.5.Therefore, the solution set of the equation |5-4r| = 17 is {-3, 5.5}.To show this solution set on a number line, we can draw a number line and mark the points -3 and 5.5 with open circles, since these values are not included in the solution set. Then, we shade the part of the number line between -3 and 5.5, since any value of r in this interval satisfies the equation. The resulting number line looks like this:

So the solution set of the equation is the interval (-3, 5.5).

With the use of the notion of proportion, the triangle's value of x is,

⇒ x = 17.89

We have to given that;

A triangle is shown in figure.

Since any relationship that always has the same ratio and amount that varies in direct proportion to one another is known as a proportional relationship.

Since, A triangle is a three-sided polygon with three vertices, three angles that add up to 180 degrees, and three sides.

Now, WE have to given that;

A triangle is shown in image.

Hence, We can formulate by definition of proportionality , we get;

⇒ 20/x = x / 16

Solve for x;

⇒ 20 × 16 = x²

⇒ 320 = x²

⇒ x² = 320

Taking square root both side, we get;

⇒ x = √320

⇒ x = 17.89

Therefore,

We can find the solution by using proportion,

So the base of the ladder is moving away from the wall at a rate of 3/4 feet per minute when the top of the ladder is 4 feet from the ground.

We can use the Pythagorean Theorem to relate the ladder's length to the distance it is from the wall. Let's call the distance from the wall "x", and the length of the ladder "y". Then:

x^2 + y^2 = 5^2

We can take the derivative with respect to time of both sides of this equation, using implicit differentiation:

2x(dx/dt) + 2y(dy/dt) = 0

Now we can plug in the values we know and solve for the rate at which the base of the ladder is moving away from the wall (which is the same as the rate at which x is increasing):

x = sqrt(5^2 - 4^2) = 3

y = 4

dx/dt = 1 (given)

dy/dt = ?

Plugging in these values, we get:

2(3)(1) + 2(4)(dy/dt) = 0

Simplifying:

6 + 8(dy/dt) = 0

The binomial theorem of expansion states that

Given that an expression is (a + b)ⁿ, the current term is

ⁿCₓ * (a)ˣ * (b)ⁿ ⁻ ˣ

(x + 4y)³ = ³C₀ (x)⁰(4y)³ +³C₁ (x)¹(4y)² + ³C₂ (x)²(4y)¹ + ³C₃ (x)³(4y)⁰

Step-by-step explanation:

The explanation is attached below.

Answer:

Step-by-step explanation:

if CB = 1/2 of AB it is understood that it is half of an equilateral triangle and AC is the height, three sides and three congruent angles, the sum of the internal angles of a triangle is 180°, therefore 180:3=60° , but the height divides the angle A in two therefore 30°, C is a right angle so 90°

The distance between the points A (3, 3) and B (6, 6) include the following: 4.24 units.

In Mathematics and Geometry, the distance between two (2) end points that are on a coordinate plane can be calculated by using the following mathematical equation:

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Where:

x and y represent the data points (coordinates) on a cartesian coordinate.

Note: Each interval on the coordinate plane represent 1 unit.

By substituting the given end points into the distance formula, we have the following;

Distance = √[(6 - 3)² + (6 - 3)²]

Distance = √[(3)² + (3)²]

Distance = √[9 + 9]

Distance = √18

Distance AB = 4.24 units.

To calculate the quantity produced from fabrication and finishing hours for Stoneage Surfboards, you would need to have additional information such as the production rate or efficiency of the fabrication and finishing processes. Without specific data on the production rate, it is not possible to determine the exact quantity produced.

However, if you have the production rate, you can use the following formula:

Quantity Produced = Production Rate × Fabrication and Finishing Hours

For example, if the production rate is 5 surfboards per hour and you have 8 hours of fabrication and finishing time, the calculation would be:

Quantity Produced = 5 surfboards/hour × 8 hours = 40 surfboards

Remember to adjust the units and variables based on the specific information and units of measurement used in Stoneage Surfboards' production processes.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let's first expand the left side of the given equation:

(2x+5)a + (x+3)b = 2x+4

2xa + 5a + xb + 3b = 2x + 4

Now, let's group the terms with x and the terms without x:

(2a + b)x + (5a + 3b) = 2x + 4

We can see that the coefficients of x are equal on both sides, so we can equate the coefficients of x and the constant terms separately:

2a + b = 2 (1)

5a + 3b = 4 (2)

Solving these two equations, we get:

a = 2/7

b = 8/7

Now, we can substitute these values of a and b into the expression (a-b)^2 and simplify:

(a-b)^2 = (2/7 - 8/7)^2

= (-6/7)^2

= 36/49

Therefore, the value of (a-b)^2 is 36/49.

The largest interval over which the general solution is defined is (-∞, ∞).

We have the differential equation:

(1 + x) *dy/dx - xy = x + x^2

To solve this, we first find the integrating factor:

μ(x) = e^∫-x dx/(1+x) = e^-ln|1+x| = 1/(1+x)

Multiplying both sides by the integrating factor, we get:

(1/(1+x)) * (1 + x) *dy/dx - xy/(1+x) = x/(1+x) + x^2/(1+x)

Simplifying, we get:

dy/dx + (y - x)/(1+x) = x/(1+x)

Now, we can use an integrating factor again:

μ(x) = e^∫(1/(1+x)) dx = e^ln|1+x| = 1+x

Multiplying both sides by the integrating factor, we get:

(1+x)*dy/dx + (y - x) = x

Simplifying, we get:

(1+x)*dy/dx + y = x + y

Separating variables and integrating, we get:

ln|y| = ln|x+y| - ln|1+x| + C

y = C(x+1)/(1+x)

Thus, the general solution is y = C(x+1)/(1+x), where C is a constant.

To find the largest interval over which the general solution is defined, we need to check for any singular points. We can see that the denominator (1+x) can never be zero, so there are no singular points. Therefore, the general solution is defined for all x.
