We need to know how to solve quadratic equation for this problem. The solution of the equation is x=1 and x=10.
An equation that has a variable with maximum degree two is called a quadratic equation. A quadratic equation can be solved by factorization method. Factorization method is a method where we group the variables together to find common factors among them. The common factors give the solution of the equation. Since a quadratic equation has variable of degree two it has two solutions. The roots of a quadratic equation can be real and unequal, real and equal or imaginary. If we solve the given equation we get a quadratic equation.
[tex]\frac{1}{x} +\frac{1}{x-10} =\frac{x-9}{x-10} \\\frac{x-10+x}{x(x-10)} =\frac{x-9}{x-10} \\2x-10=x(x-9)\\2x-10=x^{2} -9x[/tex]
[tex]x^{2} -9x-2x+10=0\\x^{2} -11x+10=0\\x^{2} -10x-x+10=0\\x(x-10)-1(x-10)=0\\(x-1)(x-10)=0\\[/tex]

What is the perimeter of the triangle
The perimeter of the triangle is 40 units
Perimeter of a triangleFrom the question, we are to determine the perimeter of the given triangle
From the given diagram, we can observe that the triangle is a right triangle
The vertical length of the triangle is 15 units
and the horizontal length of the triangle is 8 units
Thus,
We can find the hypotenuse by using the Pythagorean theorem
Let the hypotenuse be h
Then,
h² = 15² + 8²
h² = 225 + 64
h² = 289
h = √289
h = 17 units
Now, for the perimeter of the triangle
The perimeter of a triangle is the sum of all its three sides
Thus,
The perimeter. P, of the triangle is
P = 15 + 8 + 17
P = 40 units
Hence, the perimeter of the triangle is 40 units

Write an equation for each line.
y-intercept-5/2, x-intercept-1/3
a.y = -5/2x -1/3
c. y = 2.5x + 7.5
b. y = 7.5x + 2.5
d. y = "-7.5x" - 2.5
The equation of the line is y = -7.5x - 2.5
How to determine the equation of the line?The given parameters are
y-intercept = -5/2
x-intercept = -1/3
A linear equation is represented s
y = mx + c
Where
c = y-intercept = -5/2
So, we have:
y = mx - 5/2
The equation x-intercept = -1/3 means that
y = 0 and x = -1/3
So, we have
0 = -1/3m - 5/2
This gives
1/3m = -5/2
Evaluate
m = -15/2
Substitute m = -15/2 in y = mx - 5/2
y = -15/2x - 5/2
Rewrite as
y = -7.5x - 2.5
Hence, the equation of the line is y = -7.5x - 2.5

If m<4=119, what is m<10
Answer: So after applying concept of parallelism m<10 = 119
Step-by-step explanation:
As we have given m<119
In terms of parallelism
m< 4 = m<8
and m<8 = m<10
Therefore
m< 10 = m<4 = 119
So after applying concept we get m<10 = 119.

Note that {a = 7} and {b = 6}
First, we need to multiply 4 with {a = 7}, we get:
4(7) = 28
Then, we need to subtract {b = 6} from 28, we get:
28 – 6 = 22
Finally, this simplifies as:

the sum of interior angles is equal to exterior
A point that is Interior to an Angle is found on the Exterior of the Angle
The statement is false
How do we explain?
A point that is interior to an angle is located within the angle, not on the exterior. The interior of an angle refers to the region enclosed by the angle's sides.
A point that is interior to an angle is located within the angle, not on the exterior. When we refer to the interior of an angle, we are referring to the space enclosed by the angle's sides and vertex.
In geometric terms, an angle consists of two rays that share a common endpoint called the vertex. The interior of the angle is the region between these two rays while on the other hand, the exterior of an angle refers to the space outside the angle, beyond its sides.
In conclusion, a point that is interior to an angle is found within the angle itself, not on the exterior.

Which data type is used to store real numbers (numbers with decimal values) such as 3.2, 5.67 and 48.42?
The float type of data stores real numbers (numbers with decimal values) such as 3.2, 5.67 and 48.42.
What is data- type?A data type, in programming, is a classification that specifies which type of value a variable has and what type of mathematical, relational or logical operations can be applied to it without causing an error.
All number types that allow for the possibility of a fractional component, such as 42.7 or pi, are known as floating point types.
The precision of various floating point data types varies depending on how many bits are utilized to represent the digits, which is directly proportional to the total number of bits in the number. In the IEEE standard, for instance:
Single precision floats have a range of around 10-38 to 1038 with a precision of about 7 decimal digits using a total of 32 bits and 24 bits for the digits.Double precision floats, commonly referred to as doubles, have a precision of about 16 decimal digits and a range of roughly 10^-308 to 10^308. They require 64 total bits and 53 bits for digits.Quadruple precision floats, Quad doubles, sometimes known as double doubles, have a precision of about 34 decimal digits and a range of roughly 10^-4932 to 10^4932 using 128 total bits and 113 bits for the digits.Hence, the type of data is floating point.

After d days the total number of lily in the ponds are . It is an simple example of geometric progression.
The formula to calculate the sum of the first n terms of a geometric progression is given by: Sn = a[(rn – 1)/(r – 1)]. Where r is the common ratio and a is the first number of the progress.
Lilly pond starts with 1 Lilly pad, so a = 1and every day amount doubles, so r = 2. Total number of day is d, so n = d.
Therefore, the total number of lilly in the pond is = 1x[(2d-1)/(2-1)] = 2d-1.
