Step-by-step explanation:
A bicycle collector has 100 bikes. How many ways can the bikes be stored in four warehouses if the bikes and the warehouses are considered distinct? What if the bikes are indistinguishable and the warehouses distinct?
There are 176,851 ways to store the bikes in four distinct warehouses if the bikes are indistinguishable and the warehouses are distinct.
How to find the way to store the bike?Let's consider the two scenarios separately:
Scenario 1: Bikes and warehouses are considered distinct.
In this case, each bike and each warehouse is considered distinct. We need to find the number of ways to distribute 100 distinct bikes among 4 distinct warehouses.
To solve this, we can use the concept of stars and bars. Imagine we have 100 stars representing the bikes, and we want to separate them into 4 distinct groups (warehouses) using 3 bars.
The number of ways to distribute the bikes can be calculated as (100 + 3) choose 3:
Number of ways = (100 + 3)C3 = 103C3 = (103 * 102 * 101) / (3 * 2 * 1) = 176,851.
Therefore, there are 176,851 ways to store the bikes in four distinct warehouses if the bikes and warehouses are considered distinct.
Scenario 2: Bikes are indistinguishable, warehouses are distinct.
In this case, the bikes are indistinguishable, but the warehouses are distinct. We need to find the number of ways to distribute 100 identical bikes among 4 distinct warehouses.
This problem can be solved using the concept of stars and bars again. Since the bikes are indistinguishable, the placement of bars doesn't matter.
We can think of it as distributing the 100 bikes into 4 distinct groups (warehouses) using 3 bars. The number of ways to do this can be calculated as (100 + 3) choose 3:
Number of ways = (100 + 3)C3 = 103C3 = (103 * 102 * 101) / (3 * 2 * 1) = 176,851.
Therefore, there are 176,851 ways to store the bikes in four distinct warehouses if the bikes are indistinguishable and the warehouses are distinct.

Answer:
3 3/5
Step-by-step explanation:
5 would go into 18 3 times completely.
5 * 3 = 15
We would have 3/5 left over.
So 18/5 would be 3 3/5.
2 8/5 is also correct, but it is not written properly. 3 3/5 would be the most ideal answer.

Find an equation in standard form of the parabola passing through the points.
(1,1),(-1,-3),(-3,1) .
The values of a, b, and c are:
a = -15/4
b is unknown
c = 11/4
Substituting these values into the equation y = ax^2 + bx + c, we get the equation in standard form of the parabola:
y = (-15/4)x^2 + bx + (11/4)
To find the equation in standard form of a parabola passing through the given points (1, 1), (-1, -3), and (-3, 1), we can use the standard equation for a parabola:
y = ax^2 + bx + c
We need to find the values of a, b, and c that satisfy the equation when substituted with the coordinates of the three points.
Let's start by substituting the point (1, 1) into the equation:
1 = a(1^2) + b(1) + c
1 = a + b + c (equation 1)
Now substitute the point (-1, -3) into the equation:
-3 = a((-1)^2) + b(-1) + c
-3 = a - b + c (equation 2)
Lastly, substitute the point (-3, 1) into the equation:
1 = a((-3)^2) + b(-3) + c
1 = 9a - 3b + c (equation 3)
Now we have a system of three equations (equations 1, 2, and 3) with three unknowns (a, b, and c). We can solve this system to find the values of a, b, and c.
Solving the system of equations:
Adding equations 1 and 2, we have:
1 + (-3) = a + b + c + a - b + c
-2 = 2a + 2c
a + c = -1 (equation 4)
Subtracting equation 2 from equation 3, we have:
(9a - 3b + c) - (a - b + c) = 1 - (-3)
8a - 2b = 4
4a - b = 2 (equation 5)
We now have two equations (equations 4 and 5) with two unknowns (a and b). We can solve this system of equations.
Multiplying equation 4 by 4, we get:
4(a + c) = 4(-1)
4a + 4c = -4 (equation 6)
Adding equation 5 and equation 6:
4a - b + 4a + 4c = 2 + (-4)
8a - b + 4c = -2 (equation 7)
Now we have one equation (equation 7) with two unknowns (a and c). We can solve this equation to find the values of a and c.
Substituting equation 4 into equation 7:
8(a + c) - b + 4c = -2
8(-1) - b + 4c = -2
-8 - b + 4c = -2
b + 4c = 6 (equation 8)
Now we have two equations (equations 4 and 8) with two unknowns (b and c). We can solve this system to find the values of b and c.
Subtracting equation 4 from equation 8:
(-b + 4c) - (- b + 4) = 6 - (-1)
b + 4c + b - 4 = 6 + 1 4c - 4 = 7 4c = 11 c = 11/4
Now substitute the value of c = 11/4 back into equation 4:
a + (11/4) = -1
a = -1 - 11/4
a = -15/4
Therefore, the values of a, b, and c are:
a = -15/4
b is unknown
c = 11/4
Substituting these values into the equation y = ax^2 + bx + c, we get the equation in standard form of the parabola:
y = (-15/4)x^2 + bx + (11/4)

When b is 3, the value of the expression \(2b^3 + 5\) is 59.
To evaluate the expression\(2b^3 + 5\) when b is 3, we substitute the value of b into the expression and perform the necessary calculations.
Given that b = 3, we substitute this value into the expression:
\(2(3)^3 + 5\)
First, we evaluate the exponent, which is 3 raised to the power of 3:
2(27) + 5
Next, we perform the multiplication:
54 + 5
Finally, we add the two terms:
59
Therefore, when b is 3, the value of the expression \(2b^3 + 5\) is 59.
In summary, by substituting b = 3 into the expression \(2b^3 + 5\), we find that the value of the expression is 59.
It's important to note that the provided equation has multiple possible solutions for x, but when b is specifically given as 3, the value of x is approximately 3.78.
It's important to note that in this equation, we substituted the value of b and solved for x, resulting in a specific value for x. However, if we wanted to solve for b given a specific value of x, we would follow the same steps but rearrange the equation accordingly.

We need to check if y=8 and x = -1 are perpendicular or parallel.
The line y=8, is a straight line for which the y-values within it are equal to 8, therefore it is parallel to the x-axis.
The line x=-1, is a straight line for which all the values have the same value of x, which is -1, therefore it is parallel to the y-axis.
The lines are, therefore, perpendicular.

Triangulation is the division of a face or plane polygon into a series of triangles, usually with the limitation that each side of a triangle is fully shared by two adjacent triangles. In geometry, triangulation is the division of planar objects into triangles, or more broadly, the division of high-dimensional geometric objects into simplifications.

The price per can has been lowered by R2, making the standard can cost R7.
what is equation ?A mathematical assertion that establishes the equivalence of two expressions is known as an equation. It is made up of two sides, a left and a right side, separated by the equal sign (=). The equation, which is typically used to determine an unknown variable's value, requires that the values on both sides be equal. Exponents, logarithms, multiplication, division, addition, subtraction, and other mathematical operations can all be used in equations.
given
Let's say that the standard price per can is "x" Rand.
The revised price is (x-2) Rands if the price is decreased by R2.
The issue is that 14 cans are being offered for the customary price of 10 cans. Thus, we can construct the equation:
10x = 14(x-2) (x-2)
After finding x, we obtain:
10x = 14x - 28
-4x = -28
x = 7
The price per can has been lowered by R2, making the standard can cost R7.
