Equation of the sphere with center (-5, -3, 0) and radius 1 is (x + 5)² + (y + 3)² + z² = 1.

All points on a sphere are at a set distance from the centre, making it a three-dimensional geometric object. It is thought to be one of the most basic three-dimensional shapes and is a perfect circle.

Both a circle and a sphere are round, if you compare them. The fact that we can measure the volume and area of a sphere is due to the fact that a sphere is three-dimensional as opposed to a circle, which is a two-dimensional shape.

It is possible to formulate the equation for a sphere with centre (h, k, l) and radius r as follows:

(x - h)² + (y - k)² + (z - l)² = r²

Using the given center (-5, -3, 0) and radius 1, we can write the equation of the sphere as:

(x + 5)² + (y + 3)² + (z)² = 1²

which simplifies to:

(x + 5)² + (y + 3)² + z² = 1.

The probability that Gianna will randomly elect a brown pair or a green pair is 0.75 or 75%.

A practical technique to express the likelihood that an event will occur or not is through probability notation. When working with Venn diagrams, set notation is employed, and we use it to accomplish this.

Capital letters and various Greek characters are frequently used while notating events.

It is also possible to express probability as a percentage and it can only range from 0 to 1. The likelihood that event A will occur is frequently expressed as P (A) P(A) P(A)P, left parenthesis, A, right parenthesis.

The P(A/B) formula is written as P(A/B) = P(AB) / P(B), where the symbol denotes the intersection of events "A" and "B."

A basket containing 5 brown pair, 7 green pair, and 4 blue pair of coloured contacts. total pair of coloured contacts in basket =5+7+4=16

(0.25 s) = -1.8 m/s ,the numerical value of the vertical velocity of the car at time t = 0.25s, which was found to be -1.8m/s.

Part D:

In order to find the expression for the vertical velocity of the car, we need to use both the chain and product rules of differentiation. The chain rule states that if f(x) is a function of g(x), then the derivative of the function is equal to the derivative of g(x) multiplied by the derivative of f(x). The product rule states that if two functions, f(x) and g(x), are multiplied together, then the derivative of the product is equal to the derivative of f(x) multiplied by g(x) plus the derivative of g(x) multiplied by f(x).

Using the chain rule, we can find the derivative of the position-time equation:

y'(t) = yo'e-21 -yde (a cos(wt) + w sin(wt))

Using the product rule, we can find the derivative of the position-time equation:

v(t) = owyo'e-21 -yde (a cos(wt) + w sin(wt)) cos(wt) sin(wt) + yoe- (cos(wt) + aw cos(wt))

Simplifying the expression, we find:

v(t) = ayo'e-20t -w cos(wt) sin(wt)

Part E:

In order to evaluate the numerical value of the vertical velocity of the car at time t = 0.25s, we need to plug the given values for yo, a, and w into the expression for the vertical velocity.

Substituting the given values into the expression, we find:

v(0.25s) = 0.75e-20(-6.3)cos(6.3*0.25)sin(6.3*0.25)

Simplifying the expression, we find:

v(0.25s) = -1.8 m/s

In this example, we used the chain and product rules of differentiation to find the expression for the vertical velocity-time relationship for the car from its position-time relationship. We then used this expression to evaluate the numerical value of the vertical velocity of the car at time t = 0.25s, which was found to be -1.8m/s.

Opposite sides are congruent (AB = DC).

Opposite angels are congruent (D = B).

Consecutive angles are supplementary (A + D = 180°).

If one angle is right, then all angles are right.

The four properties of parallelogram are:

i) Opposite sides are parallel & equal.

ii) Sum of adjacent interior angles is 180°

iii) Opposite angles are equal.

iv) Diagonals bisect each other.

The quadrilateral with two pairs of parallel sides is known as a parallelogram. Equal in length and width on both sides is required. Four vertices make up a parallelogram, which also has four edges.

A parallelogram is a two-dimensional (2D) shape that has two matching pairs of opposite sides that are parallel and equal in length. The angles inside the two sides of the shape must add up to 180 degrees, which means that all of the angles must add up to 360 degrees.

A rectangle that has been pushed over slightly is all that a parallelogram really is. Because of this, finding the area of a parallelogram can be done using the same formula as finding the area of a rectangle.

According to the Function, p(-2) = -29 and p(3) = 73 are the values that we have.

The vertical line test has been used to determine if a graph accurately depicts a function. If a trendline created across the chart is moved and only ever hits it once, the chart is functional. If the line graph crosses the chart at least once, it is not a function.

The core concept of mathematics' calculus is functions. The functions are special types of relations. A function is a rule that generates a unique outcome for each input x in mathematics. A mapping or transformation in mathematics represents a function. Usually, letters like f, g, and h are used to designate these functions. The domain is the set of all possible values that can be passed into a function while it is specified. The term "range" refers to the whole set of values that the function's output is capable of producing. The co-domain is the set of possible values for a function's outputs.

This statement implies that Mike and Chance were picking apples together and that Chance picked three times as many apples as Mike.

Let's say Mike picked "x" apples. Then, according to the statement, Chance picked 3 times as many apples as Mike, which would be 3x apples.

Let x be the number of apples picked by Mike.

Then, the number of apples picked by Chance would be 3 times that, or 3x apples.

So, the equation can be written as:

x + 3x = total number of apples picked by both Mike and Chance.

Combining like terms, we get:

So the total number of apples picked by Mike and Chance together would be x + 3x = 4x apples.

Therefore, for every apple Mike picked, Chance picked three, and their combined total was four times the number of apples that Mike picked.

The statement holds for all positive integers n, and a tree with n nodes contains n-1 edges.

The statement can be proven by induction.

Base case: If a tree has one node, then it has no edges (n = 1, n-1 = 0).

Inductive step: Assume the statement is true for n = k (i.e. a tree with k nodes contains k-1 edges). We prove it is true for n = k+1.

Let T be a tree with k + 1 nodes, and let v be any node in T. Then, since T is a tree, v must have exactly one parent node and k-1 child nodes (or no child nodes at all). Let T' be the subtree of T rooted at v, which has k nodes. By the inductive hypothesis, T' has k-1 edges.

Since v has exactly one parent node, there is exactly one edge connecting it to its parent in T. Thus, T has k-1 + 1 = k edges, which means the statement holds for n = k + 1.

Therefore, by induction, the statement holds for all positive integers n, and a tree with n nodes contains n-1 edges.

The point-slope formula can be used to get the equation of the tangent line to the graph of the function f(x)=(x2 - 9)(x - 4) at the point (1, -30).

To get the slope at the position (1, -30), first take the derivative of the function:

f'(x) = (x2 - 9) (x2 - 9)

(x - 4)' = 2x - 9/x - 4

Check the derivative at x = 1 now:

f'(1) = 2(1) - 9/(1) - 4 = -93

The line has a -93 slope.

Now, enter the point-slope formula the point (1, -30) and the slope (-93):

y - (-30) = -93(x - 1) (x - 1)

If we simplify, we get:

y = -93x + 22

As a result, y = -93x + 22 is the equation of the tangent line to the graph of the function f(x)=(x2 - 9)(x - 4) at the point (1, -30).

The point-slope formula can be used to get the equation of the tangent line to the graph of the function f(x)=(x2 - 9)(x - 4) at the point (1, -30). According to the point-slope formula, the equation of the line is y - y1 = m for a given point (x1, y1) and slope (m) (x - x1). The specified point in this instance is (1, -30), and the slope of the line may be calculated by calculating the function's derivative and evaluating it at x = 1. The derivative of the function f(x) is 2x - 9/x - 4, which for x = 1 translates to -93. When the point and slope are entered into the point-slope equation, we obtain the result y - (-30) = -93(x - 1), which is abbreviated to y = -93x + 22. As a result, y = -93x + 22 is the equation of the tangent line to the graph of the function f(x)=(x2 - 9)(x - 4) at the point (1, -30).

If  you know the volume of the solid and the length of two of the three sides, b and c the length of the remaining side, a can be calculated by putting this values in the formula of volume(height*breadth*length).

The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

Various forms have various volumes. We have studied the several solids and forms that are specified in three dimensions, such as cubes, cuboids, cylinders, cones, etc., in 3D geometry. We will discover how to find the volume for each of these shapes.

Volume = a× b× c

a = V / b×c

Cubic units are used to quantify a solid's volume. For instance, the volume will be given in cubic metres if the dimensions are given in metres.

The zeros of a function can be obtained by factor method, by solving equation or on a graph.

What are zeros of a function?

The values of x for which a function f(x) becomes zero, or f(x)=0, are known as the zeros of the function.

There are 3 different ways by which we can find zeros of a function.

The 3 ways are:

1. By factor method

In order to use this strategy, we must first identify a function's factors. The roots of a function are then obtained by equating the factors with zero.

2. By solving an equation

In some functions, it can be challenging to identify the factors directly. In these situations, we first create an equation by equating the polynomial function with zero. The equation is then resolved. A function's roots are the roots of an equation.

3. On a graph

This is the simplest method for locating a function's zeros. With this approach, we must identify the point at which a function's graph touches or cuts the x-axis (i.e., the x-intercept). The zeros of a function are the locations where the graph cuts or touches the x-axis.

Hence, by these ways we can find the zeros of a function.

To solve the equation 2x^2 + 5x - 3 = 0, we can use the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

Where a = 2, b = 5, and c = -3.

Plugging in the values, we get:

x = (-5 ± √(5^2 - 4 * 2 * -3)) / 2 * 2

x = (-5 ± √(25 + 24)) / 4

x = (-5 ± √49) / 4

x = (-5 ± 7) / 4

So, the two solutions are:

x = ( -5 + 7 ) / 4 = (2) / 4 = 1/2

x = ( -5 - 7 ) / 4 = (-12) / 4 = -3

So, the two solutions to the equation 2x^2 + 5x - 3 = 0 are x = 1/2 and x = -3.

Answer:

The answer is B) x = 1/2, -3.

Step-by-step explanation:

The equation 2x^2 + 5x - 3 = 0 can be solved using the quadratic formula, which states that the solutions to a quadratic equation of the form ax^2 + bx + c = 0 are given by:

x = (-b ± √(b^2 - 4ac)) / (2a)

where a, b, and c are the coefficients of the equation and ± represents both the positive and negative square root.

In this case, a = 2, b = 5, and c = -3. Plugging these values into the formula gives us:

x = (-5 ± √(5^2 - 4 * 2 * -3)) / (2 * 2)

x = (-5 ± √(25 + 24)) / 4

x = (-5 ± √(49)) / 4

x = (-5 ± 7) / 4

So the two solutions are:

x = (-5 + 7) / 4 = 2 / 4 = 1/2

x = (-5 - 7) / 4 = -12 / 4 = -3

Therefore, the solutions to the equation 2x^2 + 5x - 3 = 0 are x = 1/2 and x = -3, which corresponds to option B) x = 1/2, -3.
