The value of s is 45 and the value of BC is 434
How to solve for s and BC?The given parameters are:
AB = 9s + 29
DC = 10s - 16
Opposite sides of rhombus are equal.
So, we have:
9s + 29 = 10s - 16
Evaluate the like terms
s = 45
Substitute s = 45 in AB = 9s + 29
AB = 9 * 45 + 29
Evaluate
AB = 434
This means that
BC = AB = 434
Hence, the value of s is 45 and the value of BC is 434

When rolling a single number cube, what are the odds, in simplest form, in favor of rolling a 4 or a 5?
A. 1:1
B. 1:2
C. 1:3
D. 1:5
Answer:
C
Step-by-step explanation:
You have a total of 6 outcomes (1,2,3,4,5,6). That is your numerator. Out of those numbers, you only want 2 of them (4 or 5), so the fractions would be 2/6 or 1/3 which can also be written 1:3
Find the maximum or minimum value of the product of two numbers whose difference is 14.
The maximum value of the product of two number whose difference is 14 is 49.
What is the maximum or minimum value of a function?The maximum or minimum value of a function is the highest or lowest value of that function.
How to determine the maximum or minimum of the product of two numbers?Let the numbers be x and y
Their product f(x,y) = xy
Since their difference is 14, x - y = 14
So, x = 14 - y
Substituting x into f(x,y), we have
f(x,y) = xy
= (14 - y)y
= 14y - y²
To find the maximum or minimum value of f(x,y) we differentiate it with respect to y and equate to zero.
So, f(x,y) = f(y) = 14y - y²
df(y)/dy = d(14y - y²)/dy
df(y)/dy = d(14y)/dy - dy²/dy
df(y)/dy = 14 - 2y
Equating to zero, we have
df(y)/dy = 0
14 - 2y = 0
14 = 2y
y = 14/2
y = 7
To determine if this gives a maximum or minimum for f(y) = f(x,y), we differentiate f'(y) again
So, df'(y)/dy = d(14 - 2y)/dy
= d14/dy + d(-2y)/dy
= 0 - 2
= -2 < 0.
Since f"(y) = -2 < 0, then y = 7 gives a maximum for f(x,y)
So, since y = 7,
x = 14 - y = 14 - 7 = 7
So, f(x,y) is maximum at x = 7 and y = 7
So, f(7,7) = 7 × 7
= 49
So, the maximum value of the product of two number whose difference is 14 is 49.

Answer: Length - 20, Width - 10
Step-by-step explanation:
First we will use the formula to find area:
Area = Length * Width --- However, since it's double the length we will do 2Length.
Area = 2x*x
Given Area = 200
Next we will solve to find Width:
[tex]2x^{2} =200[/tex]
Divide by 2:
[tex]x^{2} =100[/tex]
Take square root:
[tex]x=10[/tex]
Width = 10
Now we multiply 10 by 2, as length is twice it's width:

What is a Kernel Function?A kernel function is a way for taking input data and transforming it into the needed form of processing data.
The term "kernel" refers to a collection of mathematical functions used in Support Vector Machine to provide a window to alter data.
What is the solution deriving the expression given above?Given x = [x₁, x₂][tex]^{T}[/tex]
β(x) = [x²₁, √2 x₁ x₂, x²₂]
K (x₁, x') = β(x)[tex]^{T}[/tex] β(x')[tex]^{T}[/tex]
Hence, X' = [x₁, x₂][tex]^{T}[/tex]
→ β(x') = [x'²₁, √2 x'₁ x'₂, x'²₂]
K (x, x') = [x²₁, √2 x₁ x₂, x²₂][tex]^{T}[/tex] [x'²₁, √2 x'₁ x'₂, x'²₂]
K (x, x') = [x²₁, [x'²₁ + 2x₁ x₂ x'₁ x'₂ + x²₂ x'²₂
Because Z = x · x' (dot product of x·x')
= x₁ x'₁ + x₂x₂'
Expressing K (x,x') as a function of Z, we have
K (x₁, x') = x²₁ x'²₁ + 2x₁x₂ x'₁ x'² + x²₂ x'²₂
Simplified, we have
(x₁ x₁¹ + x₂x¹₂)² = Z²; and
[(a+b)² = a²+2ab+b₂] = z x₁x₁¹ + x₂x₁²

Using the the sum of the angles in a triangle is equal to 180°. Therefore, solve for x, first combine like terms to get 6x + 100 = 180. Using the (5x) +90° + (x + 10) = 180°. To 6x = 80. Then, using the division property of equality, x = 13. To find the measure of angle A, use the substitution property to get m/A = 5(13). Finally, simplifying the expression gets mA = 663"
The value of A has been illustrated, computed and proven based in the triangle given.
How to calculate the triangle?It should be noted that that a triangle is a shape that has three sides and the value of the addition of all the angles are equal to 180°.
Based on the information that's given, it should be noted that the value of angle A, angle B, and angle C will be equal to 180°.
In this case, the following can be deduced:
A = 5x
B = 90°
C = x + 10°
Therefore, A + B + C = 180° (sum of angles in a triangle)
5x + 90 + x + 10 = 180°
6x = 180° - 90° - 10°
6x = 80°
x = 80/6
x = 13 1/3
Therefore, the value of A will be:
= 5x
= 5 × 13 1/3
= 66 2/3
Therefore, A is 66 2/3.

Given that:
