What is the value of k if 1 2 is a root of the equation x2 kx 5 4 0?
The value of k in the quadratic equation is k = 2
What is Quadratic Equation?
A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the quadratic equation be represented as A
Now , the value of A is
x² + kx - 5/4 = 0 be equation (1)
Now , on simplifying the equation , we get
If 1/2 is the root of given equation, then it will satisfy it.
So , when x = 1/2
( 1/2 )² + k ( 1/2 ) - 5/4 = 0
( 1/4 ) + k/2 - 5/4 = 0
k/2 - 1 = 0
Adding 1 on both sides of the equation , we get
k/2 = 1
Multiply by 2 on both sides of the equation , we get
k = 2
Therefore , the value of k is 2
Hence , the value of k in the equation is 2

What is the y-intercept of 2x y =- 3?
The y-intercept of the equation 2x - y = -3 is 3 and in ordered pair form is (0,3).
What is the y-intercept of the given equation?The slope-intercept formula is expressed as;
y = mx + b
Where m is slope and b is y-intercept.
Given the equation in the question
2x - y = -3
First, we solve form for y and reorder in slope intercept form.
2x - y = -3
Subtract 2x from both sides
2x - 2x- y = -3 - 2x
- y = -3 - 2x
Divide each term by -1
y = 3 + 2x
Reorder in slope intercept form
y = 2x + 3
To find the y-intercept, replace x with zero and solve for y
y = 2(0) + 3
y = 3
Therefore, the y-intercept is 3.

How do you find the discontinuity point of a function?
discontinuity point of a function is a point at which the function is not continuous. There are three types of discontinuities: removable, jump, and essential.
A removable discontinuity is a point at which the function is not defined, but the limit of the function as x approaches the discontinuity point from both sides is equal to a finite value.
A jump discontinuity is a point at which the function is defined, but the limit of the function as x approaches the discontinuity point from both sides is not equal.
An essential discontinuity is a point at which the function is not defined and the limit of the function as x approaches the discontinuity point from both sides is infinite or does not exist.
To find the discontinuity points of a function, you can:
Plot the function on a graph and look for any breaks or gaps in the graph.

Is a length of two sides of an isosceles triangle is 4 cm and 10 cm then the length of the third side?
The length of the third side of an isosceles triangle with sides 4 cm and 10 cm is 10 cm.
We know that in an isosceles triangle, two sides are equal.
One side of the triangle is 4 cm and the other is 10 cm.
Let us consider the third side to be 4 cm,
then 4 cm + 4cm = 8 cm and it is not greater than the third side 10 cm.
Hence, the third side cannot be 4 cm.
Then the third side can be 10 cm,
therefore, 4 cm + 10 cm = 14 cm > 10cm

How will you know if a function increases and decreases?
A function increases if the output value of function increases on increasing the input value and the function decreses if the output value of function decreases on increasing the input value
As we know a function is nothing but a relation between input values and output values where each input has exactly one output.
Consider a function y = f(x)
For a given function if the value of y increases on increasing the value of x, then the function is an increasing function
If the y-value decreases on increasing the value of x, then the function is a decreasing function.
Another method is that if we need to determine whether a function f(x) is increasing or decreasing at point 'a'.
If a function is differentiable on an open interval, we calculate the derivative of function f(x)
If the derivative f′(x) > 0 on an open interval, then function f(x) is increasing on that interval.
If the derivative f′(x) < 0 on an open interval, then function f(x) is decreasing on that interval.
Therefore, if the output value of function increases on increasing the input value then the function is an increasing function and if the output value of function decreases on increasing the input value then the function is an decreasing function.

Write the equation of the line in fully simplified slope-intercept form.
The required equation of the line is y = 3x + 2 in slope-intercept form.
To write the equation of a line in slope-intercept form, we need to know the slope of the line and the y-intercept. The slope of a line is defined as the change in y divided by the change in x for two points on the line.
According to the given graph, the required solution would be as:
For the given points (2, 2) and (4, 8),
So, the slope is : m = 8 - 2 / 4 - 2 = 6 / 2 = 3.
With the slope and y-intercept, we can write the equation of the line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
For the point (2, 2), the y-coordinate is the y-intercept, so the y-intercept is 2.
So, the equation is y = 3x + 2

(i) On which day he saves 7.75?
(ii) Find the difference between the amount saved by Rajiv on 25th day and 14th day.
(iii) Find the sum of amount saved on first 10 days.
Step-by-step explanation:
first we come up with a formulae:
Amount of money saved = 2.25+0.25x,
where x is the number of days
Answer:
1. 7.75 = 2.25 + 0.25(x)
7.75 - 2.25/ 0.25 = x
x = 20
2. 2.25+0.25(25) - 2.25 +0.25(14)
= 9.75
3. 2.25 + 0.25(10)
= 4.75
I hope i explained it well...
( i ) 21st day he saves 7.75
(ii) the difference between the amount saved by Rajiv on the 25th day and the 14th day is 2.75 rupees.
(iii) the sum of the amount saved in the first 10 days is 5 rupees.
Solution: (i) given: on each succeeding day he increases his saving by 25 paise.
2.75 rupees he saves on the first day
so = 2.75 +(0.25×20)
= 2.75+5
= 7.75 rupees
(ii) amount saved by Rajiv on the 25th day is:
= 2.75+(0.25×24)
= 2.75 + 6
= 8.75
amount saved by Rajiv on the 14th day is :
=2.75+(0.25×13)
=2.75+3.25
=6
therefore the difference between Rajiv' saving on the 25th day and the 14th day is : = 8.75-6
= 2.75
(iii) the sum of the amount saved in the first 10 days is :
= 2.75+(0.25 ×9)

What is the multiplicity of 0?
The multiplicity of 0 is the number of times that 0 appears as a root of a polynomial equation.
In other words, it is the number of times that 0 is a solution to the equation. For example, the equation x^2 - 4x + 4 has two solutions, 0 and 4. The multiplicity of 0 is therefore 2, since 0 is a repeated solution.
If a polynomial equation has only one 0 as a solution, the multiplicity of 0 is 1. In some cases, a polynomial equation may have no 0s as a solution, in which case the multiplicity of 0 is 0.
In general, the multiplicity of a number is the number of times it appears as a solution to a polynomial equation. For example, the equation x^2 - 2x + 8 has two solutions, 2 and 4. The multiplicity of 2 is 1, since 2 appears only once as a solution, while the multiplicity of 4 is 2, since 4 appears twice as a solution.
