In the slope ratio, the change in the X-coordinates from one point to another on a line is the________.
A. Prortional relationship
B. Slope
C. Rise
D. x2- x1
E. Run
F.y2 - y1
Answer:
A. if not then b.
Step-by-step explanation:
The change in the X - coordinates from one point to another on a line is given by x₂ - x₁ = Δx.
What is ratio?Ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.We have the change in the X - coordinates from one point to another on a line.
In a slope ratio, the change in the X - coordinates from one point to another on a line can be represented as -
x₂ - x₁ = Δx
Therefore, the change in the X - coordinates from one point to another on a line is given by x₂ - x₁ = Δx.

A homeowner has $360 to spend on building a fence around a rectangular garden. Three sides of the fence will be constructed with wire fencing at a cost of $2 per foot. The fourth side is to be constructed with wood fencing at a cost of $6 per foot. Find the dimensions of the rectangle that will maximize the area of the rectangle.
Answer:
The width is 22.5 feet and the length 45 feet.
Step-by-step explanation:
Let l represent the length of the rectangle and w represent the width of the rectangle. The cost of the fence (C) is:
C = 2l + 2w + 2l + 6w
C = 4l + 8w
360 = 4l + 8w
360 = 4(l + 2w)
90 = l + 2w
l = 90 - 2w
Area (A) of rectangle = length * width
A = l * w
Put l = 90 - 2w
A = (90 - 2w)w
A = 90w - 2w²
The maximum area is at A' = 0, hence:
Differentiating gives:
A' = 90 - 4w
Put A' = 0
0 = 90 - 4w
4w = 90
w = 22.5 feet
l = 90 - 2w = 90 - 2(22.5) = 45 feet
Hence the width is 22.5 feet and the length 45 feet.
A rectangular playground has dimensions and area as shown below.
Complete the work to find the dimensions of the rectangle.
x(4x + 5) = 450
4x2 + 5x = 450
4x2 + 5x – 450 = 0
(4x + 45)(x – 10) = 0
The rectangle has a width, x, of
, and a length of
.
9514 1404 393
Answer:
x = 10width = 10length = 45Step-by-step explanation:
The remaining work is to identify the values of x that make the factors zero:
4x +45 = 0
x = -45/4 . . . . negative dimensions are not useful
x -10 = 0
x = 10
The width is x, so the width is 10.
The length is 4x+5, so the length is 4·10+5 = 45.
The rectangle has a width, x, of 10 and a length of 45.

What are permutation and combination?Combination and permutation are two different ways of grouping elements of a set into subsets in mathematics. The elements of the subset can be listed in any order in a combination. The elements of the subset are listed in a specific order in a permutation.
Given that Raman and Raj go to a party each having Rs. 100, If they decide to expend Rs. 150.
The number of the spending will be calculated as,
Raman + Raj = 150
100 + 50 = 150
50 + 100 = 150
75 + 75 = 150
The number of ways will be three.

What are the measures of angles B and C?
Figure ABCD is a parallelogram.
A.B = 15°; C = 165°
B.B = 65°; C = 115°
C.B = 65°; 2C = 65°
D.B = 15°; C = 15°
For the given parallelogram, the measure of angle B is 65° and the measure of angle D is 65°. The answer is the third option.
QuadrilateralsThere are different types of quadrilaterals, for example: square, rectangle, rhombus, trapezoid and parallelogram. Each type is defined accordingly to its length of sides and angles. For example, for a parallelogram, its the opposite sides are equal and parallel. For a parallelogram is noted too that the opposite angles are equal.
The question gives the values of the angle B and D in function of n.
Therefore, considering that the opposite angles of the parallelogram (ABCD) are equal, so D=B. Thus,
6n-25=3n+20
6n-3n=20+25
3n=45
n=15°
Replacing the value of n in each angle (B and D). Then,
D=6n-25= 6*15-25= 90-25= 65°
B=3n+20= 3*15+20= 45+20 = 65°

Determine if the product CA is defined. If the product is defined, state its dimensions. Do not calculate the product.
Answer:
The product can be calculated.
The resulting matrix will have 3 rows and 3 columns.
Step-by-step explanation:
Matrix multiplication
To find the product of two matrices is only possible when the number of columns of the first matrix is equal to the number of rows of the second matrix.
If X is the first matrix with dimensions (n x m) and Y is the second matrix with dimensions (m x p), the product XY is possible and the dimensions of the resulting matrix are (n x p).
Matrix A has two rows and three columns (2x3)
Matric C has three rows and two columns (3x2)
If we wanted to calculate the product CA, the number of columns of C must be equal to the number of rows of A.
Since both numbers are 2, the product can be calculated.
The resulting matrix will have 3 rows and 3 columns.
