Answer: sand and water
Sand : The first and most important thing you need to know about sand is that you can't do a thing with it unless it's wet. Here's why: when you add water to grains of sand, the liquid forms "bridges" that connect the granules to one another. This is why damp sand sticks together, so you can shape and carve it.
Water : Use lots of water. Dry sand in its natural state is lazy stuff. It wants to lie down and spread out into all sorts of nooks and crannies. The good news is that as long as you keep gravity working for you, there is really no way to add too much water. Which brings us to our second rule.2 Let it drain. If you've ever tried to make the base of a sandcastle by filling a plastic bucket with wet sand and then trying to unmould it, you've seen how important this rule is. With no place for the excess water to drain off, the sand makes a sucking, sticking, vacuum seal with the plastic and it becomes difficult, if not impossible, to remove the bucket.This is why successful sand sculptors do not use plastic buckets or other closed moulds but build their shapes by stacking handfuls of wet sand or by tamping it down in a topless and bottomless form.
Answer:
Placement and shape/size
Step-by-step explanation:
Placement: if the castle is to stay up for two days, you need to take into consideration the tide, and how far up on the seashore it will get. You need to know for a fact the ocean will not touch it, because if it does, chances are it will dig away at the foundation, making it topple over. You also need to make it in a place That little to no people will be there, so that they will not knock it over.
Shape/size: again, if it is to stay up for two days, you need to also consider the other weather than may occur. You need a good foundation that will not topple over. You need it tall enough that if some sand blows away, it will not matter. If it rains, you should have enough sand there that it would stay, and/or have something covering it, protecting it.

equation.
The equations are H = 4x + 60 and P = 8x + 20. We need to rent 10 tables to ensure that the cost of the rental will be the same.
What is system of equations?A system of equations in algebra consists of two or more equations and looks for common answers to the equations. "A set of equations satisfied by the same set of variables is called a system of linear equations."
Let us suppose tables as x.
Given that,
The happy party rents tables for $4 per table plus a delivery fee of 60. This is expressed as:
H = 4x + 60
Party Rental rents tables for $8 per table plus a $20 delivery fee.
P = 8x + 20
To get the same cost of the rent:
H = P
4x + 60 = 8x + 20
60 - 20 = 8x - 4x
40 = 4x
x = 10
Hence, we need to rent 10 tables to ensure that the cost of the rental will be the same.

Express sin(a)+sin(2a)+sin(3a) as a product
The expression as product is sin(a)(4 + 2cos(a) - 4sin²(a))
How to express as productFrom the question, we have the following parameters that can be used in our computation:
sin(a)+sin(2a)+sin(3a)
By sine rule, we have
sin(a)+sin(2a)+sin(3a) = sin(a) + 2sin(a)cos(a) + sin(3a)
Factor out sin(a)
sin(a)+sin(2a)+sin(3a) = sin(a)(1 + 2cos(a)) + sin(3a)
Expanding sin(3a), we have
sin(a) + sin(2a) + sin(3a) = sin(a)(1 + 2cos(a)) + 3sin(a) - 4sin³(a)
So, we have
sin(a) + sin(2a) + sin(3a) = sin(a)(1 + 2cos(a) + 3 - 4sin²(a))
Evaluate the like terms
sin(a) + sin(2a) + sin(3a) = sin(a)(4 + 2cos(a) - 4sin²(a))
Hence, the product expression is sin(a)(4 + 2cos(a) - 4sin²(a))

this function represents the relationship between the radius of cylinders with a height of feet and their volume. why is this relationship between radius and volume nonlinear?
The relationship between the radius and volume of a cylinder with a height of 4 feet is nonlinear because the volume of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height. In this case, the height is fixed at 4 feet. As we change the radius, the volume changes in a nonlinear manner.
The volume increases much faster as the radius increases. This can be seen from the exponential nature of the formula, as the radius is squared. Therefore, even a small increase in the radius results in a substantial increase in the volume, making the relationship between radius and volume nonlinear.
In contrast, if the height were to be proportional to the radius, then the relationship between radius and volume would be linear. This is because the volume would be proportional to the product of the radius and height, which is a linear relationship.
Therefore, the nonlinear relationship between radius and volume, in this case, is due to the exponential nature of the formula for the volume of a cylinder and the fixed height of 4 feet.

suppose that DEF is isosceles with base DF
suppose that m
Answer: An isosceles triangle is a triangle with two sides that are congruent (equal in length). If DEF is isosceles with base DF, then DE and EF are congruent and have the same length. This means that the two sides of the triangle are equal in length, and that the angle formed by DE and EF is equal to each other (since they are congruent sides, they must also be congruent angles). The two equal angles are called the base angles of the isosceles triangle.

A 100-horsepower outboard motor at full throttle will rotate its propeller at exactly 4700 revolutions per min. Find the angular speed of the propeller in radians per second.
4700 rev per min _____ radians per sec
(Round to the nearest tenth as needed.)
Rounding to the nearest tenth, the angular speed of the propeller is 157.1 rad/s.
What do you mean by radian?A radian is a unit of measurement for angles in mathematics. It is defined as the ratio of the length of an arc of a circle to the radius of the circle. In other words, one radian is equal to the angle created at the center of a circle by an arc that is equal in length to the radius of the circle.
Radians are used as a more natural and convenient way to measure angles than degrees, especially in calculus and other branches of mathematics that deal with the study of curves and functions. For example, the trigonometric functions (sine, cosine, and tangent) are defined in terms of radians, and the derivatives of these functions are easier to work with in radians than in degrees
To convert from revolutions per minute to radians per second, we need to divide by the number of minutes in one hour and multiply by the number of radians in one revolution. We can write this conversion as:
4700 rev/min * (2π rad/rev) / (60 min/hr) = w rad/s
where w denotes the angle's rotational speed in radians per second. Plugging in the conversion factor for one revolution, we get:
w = 4700 rev/min * (2π rad/rev) / (60 min/hr) = (4700 * 2π) / 60 = 157.07 rad/s
Rounding to the nearest tenth, the angular speed of the propeller is 157.1 rad/s.

are we guaranteed that a solution exists? what is the guaranteed minimum radius of convergence for a taylor series expansion about the origin? is the solution unique?
The existence, uniqueness, and minimum radius of convergence of a Taylor series expansion about a point depend on the function being expanded. In general, there is no guarantee that a Taylor series will exist or be unique for every function.
Taylor Series ExpansionA Taylor series expansion of a function about a point is a representation of the function as an infinite sum of terms involving powers of the difference between the independent variable and the point. If the function is well-behaved near the point, its Taylor series will converge to the function within some interval around the point. The smallest such interval is called the radius of convergence.
If the function is infinitely differentiable (i.e. has derivatives of all orders) near the point, its Taylor series will converge to the function within the entire interval of convergence. In this case, the solution is said to be unique. However, if the function is not infinitely differentiable, it may not be possible to find a Taylor series that converges to the function, or there may be multiple Taylor series that converge to the function within different intervals.
The minimum radius of convergence of a Taylor series is difficult to determine in general, as it depends on the behavior of the function at infinity. In some cases, the radius of convergence can be estimated using techniques such as Cauchy-Hadamard theorem. However, in general, determining the exact radius of convergence requires knowledge of the behavior of the function at all points, not just near the point of expansion.

Show the polynomial -15y + 12y²-9y as the product of polynomials. Write each polynomial of the product in standard form.
Answer:
Step-by-step explanation:
Here are the steps to write the polynomial -15y + 12y² - 9y as a product of polynomials in standard form:
Factor out the coefficient of the linear term: -15y = -15 * y
Factor out the coefficient of the quadratic term: 12y² = 12 * y^2
Add the two factored polynomials: -15 * y + 12 * y^2 - 9 * y

a senate committee consists of 5 republicans, 6 democrats, and 2 independents. a subcommittee of 3 members is randomly chosen. what is the probability that the subcommittee (a) consists of 3 republicans?
Considering all the given information, the probability that the subcommittee consists of 3 republicans is 0.0345, or 3.45%.
To find the probability that the subcommittee consists of 3 Republican’s, we first calculate the number of ways to choose 3 Republicans out of 5:
C(5, 3) = 5! / (3! (5 - 3)!)
=5! / (3! 2!)
= (5 ×4 × 3!) / (3 × 2 × 3!)
= (5 × 4) / (2 × 2)
= 10.
The total number of ways to choose 3 members out of a committee of 5 Republicans, 6 Democrats, and 2 Independents is:
C(13, 3) = 13! / (3! (13 - 3)!)
=13! / (3! 10!)
= (13 × 12 × 11 × 10!) / (3 × 2 × 1 × 10!)
= (13 × 12 × 11) / (3 × 2 × 1)
= 286
So the probability of choosing 3 Republicans is:
P(3 Republicans) = 10 / 286 = 1/29
Therefore the probability of the subcommittee consisting of 3 Republicans is approximately 0.0345, or 3.45%.

The graph of [tex]y = x^2+px+q[/tex] has a turning point at (2,5) Find the values of p and q
Answer:
p = -4
q = 9
Step-by-step explanation:
The vertex form of a parabola is:
y = a (x − h)² + k
Given that the leading coefficient is 1 and the vertex is (2,5):
y = (x − 2)² + 5
Distributing:
y = x² − 4x + 4 + 5
y = x² − 4x + 9
Alternatively, using calculus, if y = x² + px + q, then the derivative is:
dy/dx = 2x + p
The turning point occurs when the derivative is 0:
0 = 2x + p
0 = 2(2) + p
p = -4
Plugging in and solving for q:
y = x² − 4x + q
5 = (2)² − 4(2) + q
5 = 4 − 8 + q
q = 9
