Consider the function shown on the graph. Which function does the graph represent? f(x) = (x + 3)(x + 7) f(x) = (x – 3)(x – 7) f(x) = 3(x – 3)(x – 7) f(x) = 11(x + 3)(x + 7)
The solution is Option C.
The value of the function is f ( x ) = 3 ( x - 3 ) ( x - 7 )
What is Equation of Graph of Polynomials?Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Identify the even and odd multiplicities of the polynomial functions' zeros.
Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.
The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = 3 ( x - 3 ) ( x - 7 ) be equation (1)
On simplifying the equation , we get
y = 3 ( x - 3 ) ( x - 7 )
And , the point ( 8 , 15 ) lies on the graph
Substituting the values in the equation , we get
when x = 8
y = 3 ( 8 - 3 ) ( 8 - 7 )

Two different workers are producing a specialized part for a machine. The number of parts produced per hour by the workers are as follows:
Worker A: 5, 4, 4, 6, 7, 5, 6, 3
Worker B: 4, 8, 1, 9, 2, 9, 4, 3
Both workers averaged 5 parts per hour. Which worker has the higher variance and standard deviation?
The worker B has a higher variance of σ² = 9 and standard deviation of 3
What is Standard Deviation?The standard deviation refers to a measurement of the data dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Standard Deviation is calculated by
Each number's deviation from the mean must be determined, and then squared.
Next, add up all of these values.
Divide the result by the quantity of numbers.
Then calculate its square root.
Given data ,
Let the data of worker A = { 5, 4, 4, 6, 7, 5, 6, 3 }
Let the data of worker B = { 4, 8, 1, 9, 2, 9, 4, 3 }
Now , the mean of worker A = 5
The mean of worker B = 5
So , the standard deviation of worker A is calculated as
The sum of the difference of the data from mean is
SD = √ ( 5 - 5 )² + ( 5 - 4 )² + ( 5 - 4 )² + ( 5 - 6 )² + ( 5 - 7 )² + ( 5 - 5 )² + ( 5 - 6)² + ( 5 - 3 )² / 8
On simplifying the equation , we get
SD = √ ( 12/8 )
SD = √1.5
Standard deviation σ = 1.2247449
And , the variance of worker A is σ² = 1.5
Now ,
The standard deviation of worker B is calculated as
The sum of the difference of the data from mean is
SD = √ ( 5 - 4 )² + ( 5 - 8 )² + ( 5 - 1 )² + ( 5 - 9 )² + ( 5 - 2 )² + ( 5 - 9 )² + ( 5 - 4)² + ( 5 - 3 )² / 8
On simplifying the equation , we get
SD = √ ( 72/8 )
SD = √9
Standard deviation σ = 3
And , the variance of worker A is σ² = 9
Hence , the worker B has higher standard deviation

Two of the interior angles of a polygon are 140° and 160° , the remaining and 150°. Find the number of sides of the polygon
the number of sides of the polygon 12 sides
Which polygon has a space inside?An interior angle is a shape's internal angle. The closed shape with sides and vertices is a polygon. All of the inner angles of a regular polygon are equal to one another. For instance, a square has interior angles that are all exactly right angles, or 90 degrees.
In a regular polygon, all internal angles are equal. Interior angle of a polygon = sum of interior angles number of sides is the formula for determining the amount of an interior angle.
The n-sided polygon's inner angle total equals (n-2).
180°, thus as follows:
140°+160°+ (n-2)150 = (n-2)180°
or, 300° = (n-2)(180° - 150°).
or, 300° = (n-2) 30°
or, 10= n - 2.
alternately, n = 10 + 2 = 12 sides.

The distance of AB is 117.992 meters.
What is Law of Sines?Law of sines is a law in trigonometry which states that the ratios of the angle to the opposite side of a triangle are equal.
For triangle ABC,
sin A / a = sin B / b = sin C / c
where a, b and c are the sides opposite to the angles A, B and C respectively.
Here,
∠B = 112° 10' = 112° + 0.167° = 112.167°
∠C = 15° 20' = 15° + 0.333° = 15.333°
By the angle sum property of triangle,
∠A = 180° - (∠B + ∠C)
∠A = 180° - (112.167° + 15.333°)
= 52.5°
Using law of sines,
sin A / BC = sin C / AB
sin (52.5°) / 354 = sin (15.333°) / AB
AB = [354 × sin (15.333°)] / [sin (52.5°)]
AB = [354 × 0.264] / [0.793]
AB = 117.992 meters

How to solve the system of equations?Here we want to solve the system of equations:

The solutions of the equation are x < 18 and x < - 30.
Solution on inequalities:Solutions of equations are the numerical values of the variables that will satisfy the condition in the given equation. Similarly, the solutions of inequalities are the values of variables that can satisfy the given inequality.
We can solve an inequality by adding or subtracting the same integer on both sides, or we can multiply or divide by the same number on both sides until we get the value of 'x'.
Here we have
3/4 |1/3x + 2| < 6
We can solve the above equation as follows
3/4 |1/3x + 2| < 6
Multiply by 4 on both sides
=> 4 [ 3/4 |1/3x + 2| ] < 4 × 6
=> 3 |1/3x + 2| < 24
=> | x + 6| < 24
=> x + 6 < ± 24
=> x + 6 < 24 and x + 6 < - 24
Subtract - 6 on both sides

$
The discounted price of the set of dishes would be = $63.89
How to calculate the discounted price?The original cost of the dishes = $57.68
The percentage increase of the cost of the dishes = 125%
That is,

= 7210/100 = $72.10+57.68 = $129.78
After one month, the store marked it down by 50%, therefore the discounted price;
= 50/100 × 129.78/1

If f(1) = 5 and f(n) = 5f(n-1) + 5 then find the value of f(3)
The value of function for f(5) is 3125.
What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given that, f(1) = 5 and f(n) = 5f(n − 1)
Now, for finding the the 5th term we have to find the remaining four term before the 5th term.
So, n=2
f(2) = 5f(1)
f(2)= 5(5)
f(2)= 25
Now, n=3
f(3) = 5f(2)
f(3)= 5(25)
f(3)= 125
Now, n=4
f(4) = 5f(3)
f(4)= 5(125)
f(4)= 625
Now, n=5
f(5) = 5f(4)
f(5)= 5(625)
f(5)= 3125
Hence, the value of function for f(5) is 3125.
