According to the information, the cuboid in the image is missing 3 faces of the following dimensions 1 face of 1 * 4, 1 face of 1 * 3 and 1 face of 3 * 3.
How to complete the cuboid?To complete the cuboid we must take into account that there are already three of its faces. Therefore, we must identify which faces are missing. As we know, cuboids are three-dimensional figures that have 6 faces. Another characteristic of non-regular cuboids is that they have pairs of equal faces.
Based on the information above, we can infer that the missing sides of this cuboid have the same dimensions as the existing sides on the graph. Therefore, the following sides would be missing:
1 face of 1 * 41 face of 1 * 31 face of 3 * 3Additionally, to know the surface of the area we must count the number of squares that the figure has in total, in this case it would be 38 squares, so the area is 38 units²

The probability that the point does not land in triangle T is 7/8 or 0.875.
The probability that a randomly placed point inside a rectangle does not land in triangle T. To answer this question, we need to calculate the areas of the rectangle and triangle T and then find the probability.
Let's assume the dimensions of the rectangle are 6 units by 4 units, which gives it an area of 24 square units. For triangle T, it seems to have a base of 3 units and a height of 2 units. Using the formula for the area of a triangle (0.5 * base * height), the area of triangle T is 3 square units.
Now, to find the probability of the point not landing in triangle T, we will first determine the area of the remaining space in the rectangle. This can be found by subtracting the area of triangle T from the total area of the rectangle:
Area of remaining space = Area of rectangle - Area of triangle T
Area of remaining space = 24 square units - 3 square units = 21 square units
Finally, the probability of the point not landing in triangle T is the ratio of the remaining space area to the total rectangle area:
Probability = (Area of remaining space) / (Area of rectangle)
Probability = 21 square units / 24 square units = 7/8
Therefore, the probability that the point does not land in triangle T is 7/8 or 0.875.

4x10^0/6.5x10^2
Answer:
\(\frac{2}{325}\)
Step-by-step explanation:
Assuming you mean simplify \(\frac{4*10^{0} }{6.5*10^{2} }\), first you need to simplify the numerator.
Simplifying the numerator:
\(4*10^{0}=4*1=4\)
This simplifies to 4 because any expression raised to the 0 power is 1.
Simplifying the denominator:
\(6.5*10^{2} =6.5*100=650\)
Dividing the numerator by the denominator:
\(\frac{4}{650} =\frac{2}{325}\)
Evaluate the indefinite integral. [2√2+#de
The given indefinite integral evaluates to ∫(2√2 + #de) = (4/3) (2\(^3^/^2\)) + e + C.
The given indefinite integral is: ∫(2√2 + #de).
We know that the integral of √x is (2/3) x\(^3^/^2\)
The given integral can be re-written as follows: ∫(2√2 + #de) = 2∫√2 #de + ∫#de.
Since the integral of a constant term is just the product of the constant and the variable, the second integral is given by: ∫#de = e + C, where C is the constant of integration.
On the other hand, the first integral can be calculated using the integral of √x, which is given by: (2/3) x\(^3^/^2\)+ C.
Putting this back into the original integral, we have:
∫(2√2 + #de) = 2∫√2 #de + ∫#de
= 2(2/3) (2\(^3^/^2\)) + e + C
= (4/3) (2\(^3^/^2\))) + e + C.
In summary, the given indefinite integral evaluates to ∫(2√2 + #de) = (4/3) (2\(^3^/^2\)) + e + C.

What are the excluded values of x for
Answer:
x = - 2, x = 9
Step-by-step explanation:
Given
f(x) = \(\frac{x^2-9x}{x^2-7x-18}\)
The denominator of f(x) cannot be zero as this would make f(x) undefined.
Equating the denominator to zero and solving gives the values that x cannot be.
x² - 7x - 18 = 0
(x - 9)(x + 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 9 = 0 ⇒ x = 9
The excluded values are x = - 2, x = 9
Factorise the following:
a) x² + 10x + 16 answer
Factoring polynomials is breaking them down to the products of other smaller polynomials. Identifying the greatest common divisor (GCF) is an important first step because it will reduce the number of factors in each term and thus make factoring easier. In addition to polynomials, it can be factored by decomposition of the intermediate term or by difference of squares. Then, the Zero Product Property can be applied to solve the equation.

.
To simplify the expression 5√8 + √3, we can simplify each radical term separately and then combine them.
First, let's simplify the radical terms:
√8 can be simplified as 2√2 because 8 can be factored into 4 * 2, and √4 is equal to 2.
√3 cannot be simplified further since 3 is a prime number.
Now, let's substitute the simplified radical terms back into the expression:
5√8 + √3 becomes 5(2√2) + √3.
Next, we can multiply the coefficients outside the radicals:
5(2√2) is equal to 10√2.
Putting it all together, the simplified expression is:
10√2 + √3.
So, 5√8 + √3 simplifies to 10√2 + √3.

3v + 11 = 50 what’s the answer ?
Answer:
v=13
Step-by-step explanation:
3(13) = 39+11 = 50
Answer:
Our main goal is to isolate the variable here (v).
And if we want to solve this equation,
we must utilize inverse operations.
Given that:-
3v + 11 = 50
We always first get rid of the constants.
And in this case, 11 is our constant.
So the inverse operation of addition is subtraction (because 11 is being added)
-11 -11
3v = 39
Now, we are left with a co-efficient.
To isolate v, we must apply the inverse operation of multiplication which is division (because 3 and 'v' are being multiplied).

19/9 ÷ 2/3 - 25/4 x 2/5
dividing fractions you can multiply and use reciprocal of the fraction (means you switch the top and bottom numbers)
19/9 x 3/2 - 25/4 x 2/5
you can reduce the top and bottom numbers to make them smaller by dividing. find a common number to divide them by, you can cross out the numbers and just put the new equation below

for each of the following, show that the differential form is not exact, but becomes exact when multiplied through by the given integrating factor
To determine if a differential form is exact, we need to check if its partial derivatives satisfy the condition of equality. If the differential form is not exact, we can multiply it by an integrating factor to make it exact.
Given a differential form of the form M(x, y)dx + N(x, y)dy, we can determine if it is exact by checking if ∂M/∂y = ∂N/∂x. If this condition is not satisfied, the differential form is not exact. However, we can multiply the differential form by an integrating factor to make it exact.
By multiplying the original differential form by an integrating factor, which is usually a function of either x or y, the resulting form will have equal partial derivatives, satisfying the condition for exactness. The integrating factor effectively "corrects" the form and makes it exact.
By finding the appropriate integrating factor and multiplying it with the given differential form, we can transform it into an exact form. This process is a fundamental technique in solving certain types of differential equations and allows us to find solutions that would otherwise be challenging to obtain.

This problem requires optimization over a closed interval.
How to find a positive number x such that the sum of 4x and \(x^2\) is as small as possible?To find a positive number x such that the sum of 4x and \(x^2\) is as small as possible, we need to minimize the objective function \(4x + x^2.\)
Since we are looking for a positive number, the interval of interest is [0, ∞), which is a closed interval because it includes its endpoints.
In optimization problems, a closed interval is used when we want to consider all possible values within a given range, including the endpoints.
In this case, we want to explore all positive values of x starting from 0, which is the lower bound of the closed interval [0, ∞).
By finding the minimum value of the objective function within this closed interval, we can determine the value of x that minimizes the sum of 4x and \(x^2\).

therefore
30 = k/4
120 = k
y = 120/10 = 12
FYI :

y = kx
The value of y will be 12 when x is equal to 10.
What is inverse variation?The relationship between two variables known as "inverse variation" occurs when the value of one variable increases while the value of the other variable decreases.
Given that, y varies inversely with x.

Answer:
m = 129°
Step-by-step explanation:
Finding the unknown angle in the polygon:Find the sum of angles of the polygon using the formula,
Sum of angles of polygon = (n - 2)*180
n is the number of sides. n = 6
= ( 6- 2) *180

Sum of the angles of given polygon = 720
90 + 146 + 90 + 135 + m + 130 = 720
m + 591 = 720
m = 720 - 591
