The building is 141 cm tall when a pole that is 3.1 m tall casts a shadow that is 1.68 m long.
What is ratio ?
ratio can be defined as the given value divided by the total value, called as the ratio.
Given,
A pole that is 3.1 m tall casts a shadow that is 1.68 m long.
At the same time, a nearby building casts a shadow that is 48.25 m long
to solve this, use proportions. The height of the pole corresponds to the height of the building; the shadows are corresponding:
3.1/ x = 1/45.5
x = 3.1* 45.5
x = 141.05
Hence, the building is 141 cm tall when a pole that is 3.1 m tall casts a shadow that is 1.68 m long.

Is the relation shown below a function? Explain.
Is the relation shown below is not a function.
Define function?A relationship between two sets known as the domain and the co domain, where there is one output for each input, is called a function. The amounts represent a relation if you have more than one output for a specific input, or if the elements of A and B do not map uniquely. The vertical line test, which states that at any point if a vertical line produces two intercepts of the curve, the curve cannot be a function, can be used to demonstrate that a relationship graph is a function.Given are two sets with {5,10,15,20} and {10,20,30,40,50} where there is a mapping.We find that while 5,10,15 have unique mappings while 20 have two mappings.Since there is an element in the I set have two images, this cannot be a function.To learn more about function refer to:

What is the derivative of 7e to the 7x?
The derivative of 7e to the 7x is 7e to the 7x * 7ln(e) * 7. The derivative of 7e to the 7x can be found by first taking the natural logarithm of the base, in this case e7x.
1. Take the natural logarithm of the base: ln(e7x)
2. Take the derivative of the natural logarithm: 7x*ln(e)
3. Apply the chain rule: 7e7x * 7ln(e) * 7
The derivative of 7e to the 7x can be found by first taking the natural logarithm of the base, in this case e7x. The natural logarithm of e7x is ln(e7x). Taking the derivative of the natural logarithm yields 7x*ln(e). We then apply the chain rule to get the final result of 7e7x * 7ln(e) * 7. In other words, the derivative of 7e to the 7x is equal to 7 multiplied by e raised to the 7x power, multiplied by 7ln(e), and then multiplied by 7 once more. This can be simplified to 7e7x * 7ln(e)7.

what is the smallest integer greater than 38 that cannot be the length of the hypotenuse of a right triangle with integer side lengths?
The smallest integer greater than 38 which cannot be the length of the hypotenuse of a right triangle is 39.
Since 39 is divisible by 3, it cannot be the hypotenuse in any Pythagorean triples. Because for primitive Pythagorean triples, the hypotenuse is never divisible by 3.
What is a primitive Pythagorean triple?A primitive Pythagorean triple is one where a, b and c are coprime (which is, they have no common divisor larger than 1). For example, (3, 4, 5) is a primitive Pythagorean triple while (6, 8, 10) is not. For any primitive Pythagorean triple the integer c or the hypotenuse cannot be divisible by 3. Divisibility by 3 is only reserved for spots a and b.
There are an infinite number of Pythagorean triples. If 2n+1 is a square, it forms a Pythagorean triple. But 2n+1 comprises all the odd numbers; each of other square numbers is odd; there are an infinite number of odd squares; thus, there are an infinite number of Pythagorean triples.

The width of rectangle is 10 units.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Perimeter of rectangle = 116 units
let the width be x.
then the length is 5x - 2.
so, Perimeter of rectangle = 116 units
2 (5x -2 + x)= 116
2(6x - 2) = 116
6x - 2 = 58
6x = 60
x= 10
So, the width is 10 units and length is 5(10)-2 = 48 units

For instance, in the relation (4, 1), (4, 2), the x-value of 4 has y-values of 1 and 2, indicating that this relation is not a function. The connection is a function if each x-value has a single corresponding y-value.
An ordered group of pairs makes up a relation (x, y). A pair that has two values stated in a specific order between parenthesis is known as an ordered pair. It is made up of the x coordinate (abscissa) and the y coordinate (ordinate). For greater visual comprehension, it helps to locate a point on the Cartesian plane.

Answer:
The first step in solving this system of equations by elimination method is to eliminate one of the variables by adding or subtracting the two equations.
-9x - 4y = 1
3x + 3y = 3
If we multiply the first equation by 3 and the second equation by -9, we get:
-27x - 12y = 3
-27x - 27y = -27
Now we can add these two equations:
-12y = -24
y = 2
Now we can substitute this value of y back into one of the original equations to find the value of x.
-9x - 4(2) = 1
-9x - 8 = 1
-9x = 9
x = -1
So the solution of this system of equations is (x,y) = (-1,2)
Answer:
You just have to plug in one equation into the other, though you might already know this but the answer would be,

Which type of polynomial is x² 9x 20?
The answer to the polynomial x^2 + 9x + 20 is x^2 + 9x + 20.
This is a second-degree polynomial, which is a polynomial with the highest power of the variable being 2. It is written in the standard form as ax^2 + bx + c, where a, b, and c are coefficients, and x is a variable. In this case, a = 1, b = 9, and c = 20.
To calculate this polynomial , we first substitute each value into the formula:
1x^2 + 9x + 20
Next, we multiply each coefficient with its corresponding variable:
1(x^2) + 9(x) + 20
Finally, we expand the terms and add them together to find the sum:

In the given question, we have to find the slope of the line (-3, 4) and (0, 2).
A line's slope is defined as the ratio of the change in the y coordinate to the change in the x coordinate.
The given points are (-3, 4) and (0, 2).
We can find the slope from the given point using the formula

From the given points;
x(1) = -3, y(1) = 4, x(2) = 0, y(2) = 2

Since 6 + 6 equals 12, the variable x in the case above equals 6. If we are aware of the values of our variables, we can replace the variables with those values before evaluating the expression.
When the variables and constants of an expression are given values, the outcome of the computation it describes yields the expression's value. The quantity that the function assumes for these argument values is the value of the function, given the value(s) assigned to its argument(s).

The time required for the new guy to finish the car is given by the equation A = 10/3 hours = 3 1/3 hours
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the time required for the new guy to finish the car be A
Now , the equation will be
The total time worked by the two mechanics = 2 hours
The time for the 1st person to finish the car = 6 hours
So , the amount of work done in 2 hours by 1st person = 2/6 = 1/3 of total
The time for the 2nd person to finish the car = 8 hours
So , the amount of work done in 2 hours by 2nd person = 2/8 = 1/4 of total
And , the remaining work = 1 - ( 1/3 + 1/4 )
On simplifying the equation , we get
The remaining work = 1 - ( 7/12 ) = 5/12 of the work
Now , the time required for the 2nd person to complete 5/12 of the work =
A = 5/12 x 8
A = 5 x 2/3
A = 10/3
A = 3 1/3 hours = 3 hours and 20 minutes
Hence , the time required is 3 hours and 20 minutes
