Answer:
[tex]f(x)=3x^4+51x^2+48[/tex]
Step-by-step explanation:
As n = 4, the degree of the polynomial is 4.
Therefore, the function cannot have more than 4 distinct roots.
[tex]\implies f(x)=a(x-p)(x-q)(x-r)(x-s)[/tex]
If a complex number z is a root of f(z) = 0 then its complex conjugate is also a root. Therefore:
If i is a root, then -i is also root.If 4i is a root, then -4i is also root.[tex]\implies f(x)=a(x-i)(x+i)(x-4i)(x+4i)[/tex]
[tex]\implies f(x)=a(x^2-i^2)(x^2-16i^2)[/tex]
[tex]\implies f(x)=a(x^2-(-1))(x^2-16(-1))[/tex]
[tex]\implies f(x)=a(x^2+1)(x^2+16)[/tex]
Given f(-1) = 102, then:
[tex]\begin{aligned}\implies f(-1)=a((-1)^2+1)((-1)^2+16)&=102\\a(1+1)(1+16)&=102\\a(2)(17)&=102\\34a&=102\\a&=3\end{aligned}[/tex]
Therefore:
[tex]\implies f(x)=3(x^2+1)(x^2+16)[/tex]
[tex]\implies f(x)=3(x^4+17x^2+16)[/tex]
[tex]\implies f(x)=3x^4+51x^2+48[/tex]

The area of the large square = 9/4 square inches
There is a total of 25 small equally sized squares inside the large square.
The shaded portion given contains 4 such small equally-sized squares. This shaded portion has an area of 9/25 square inches.
We will first find the area of one small sized square and then will use it to find the area of the large square as the large square is made of 25 such small squares.
That is, area of 4 small squares = 9/25
So area of one small square = Area of 4 small squares/ 4
= (9/25)/4
= 9/(25 x 4)
= 9/100 square inches
Now to find the area of the large square, multiply the area of one small square with the total number of small squares contained in the large square.
That is, Area of the large square = (9/100) x 25
= 9/4 square inches

A dealer purchased an old car for 70,000. He spent 17,500 on its repair and painting. Due to lack of demand he had to dispose it at a loss of 12%. What was the selling price of the car?
The selling price of the car is 77,000.
First, let's define what a selling price is.
The selling price is the price the customer pays to purchase the good.
Selling price = Cost price – (100% Loss)/100
We are told that the car cost 70,000 and that 17,500 was lost (12%) in repairs and painting.
The car's total cost is equal to 70,000 + 17,500 = 87,500.
So, the car's cost price is 87,500.
Selling price = 100/12/100 x cost price
= 100/12/100 x 87,500
= 0.88 x 87,500
= 77,000
Consequently, the car is being sold for $77,000.

Find the area of the following polygon if AB= 12 cm, AC = 2.4 cm, CE = 6 cm, AD 4.8 cm, CF = GE = 3.6 cm, DH = 2.4 cm. =
Answer:
50.40 cm2
Step-by-step explanation:
Area of the polygon AFGBH = Area of ∆ACF + Area of rectangle FCEG + Area of ∆GEB + Area of ∆ABH
= 3.6 cm2 + 4.32 cm2 + 21.6 cm2 + 6.48 cm2 + 14.4 cm2
= 50.40 cm2
Hence, the required area = 50.40 cm2.
Explain why the statement line LR ≅ line RL and ∠CBA ≅ ∠ABC are both true by the Reflexive Property of Congruence.
The reflective Property of Congruence states that any figure is congruent with itself, therefore line LR ≅ line RL and ∠CBA ≅ ∠ABC.
What is congruence?If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent or to be in the relation of congruence.
Reflexive Property of Congruence said that an angle line segment or any shape is congruent with itself.
For example, a line segment with a length of 5 meters will be the same as another line with 5 meters or a copy of that line so both will be congruent.
Line LR and RL are the same in length thus line LR ≅ line RL.
Angle CBA and angle ABC are the same thus ∠CBA ≅ ∠ABC.
Hence "The reflective Property of Congruence states that any figure is congruent with itself, therefore line LR ≅ line RL and ∠CBA ≅ ∠ABC".

A transversal interersects two parallel lines. The measures of a pair of alternate interior angles are 5v and 2w. The measures of a pair of same-side exterior angles (consecutive exterior) are 10w and 5v. What are the values of w and v?
Answer: [tex]v=6, w=15[/tex]
Step-by-step explanation:
The pair of alternate interior angles are congruent, so [tex]5v=2w \implies 10w=25v[/tex].
The consecutive exterior angles are supplementary, so
[tex]10w+5v=180\\\\25v+5v=180\\\\\\30v=180\\\\v=6\\\\\implies w=2.5(6)=15[/tex]
9(x+y)=3ay solve for y
When we solve the linear equation for y, we will get:
8*x/(3*a - 9) = y
That is the solution for the variable y.
How to solve the linear equation for y?
Here we have the linear equation:
9*(x + y) = 3*a*y
Where x, y, and a are variables.
We want to solve this linear equation for y, this means that we need to isolate y in one side of the equation, to do so, let's start by expanding the left side:
9*(x + y) = 3*a*y
9*x + 9*y = 3*a*y
Now we move all the terms with y to the right side.
8x = 3*a*y - 9*y = (3*a - 9)*y
Now we divide both sides by 3*a - 9 to get:
8*x/(3*a - 9) = y
That is the equation solved for y.

it is given that
Ari walked a distance of 22 miles with speed of 2 miles per hour .
Beth walked a distance of 1 mile with the speed of 1 mile per hour.
Cindy walked for the time 1 hour and 21 minutes .

Square 12 12 144 1 144
Triangle 12 15 90 4 360
The surface area is 504 square inches
How to determine the surface area?The square prism represents the given parameter
On the figure, we have the following highlights:
Shape: Square
Number of shapes = 1Base length = 12 inchesHeight = 12 inchesAlso, we have
Shape: Triangle
Number of shapes = 4Base length = 12 inchesHeight = 15 inchesThis means that
Area of 1 square = Base length * Height
Area of 1 square = 12 inches * 12 inches
Area of 1 square = 144 square inches
So, the area of all squares in the figure is
Area of all squares = 1 * 144 square inches
Area of all squares = 144 square inches
Also, we have
Area of 1 triangle = 0.5 * Base length * Height
Area of 1 triangle = 0.5 * 12 inches * 15 inches
Area of 1 triangle = 90 square inches
So, the area of all triangles in the figure is
Area of all triangles = 4 * 90 square inches
Area of all triangles = 360 square inches
The surface area of the figure is
Surface area = Area of all triangles + Area of all squares
This gives
Surface area = 360 square inches + 144 square inches
Evaluate
Surface area = 504 square inches
Hence, the surface area of the prism is 504 square inches

On a certain hot summer's day, 273 people used the public swimming pool. The daily prices are $1.25 for children and $2.50 for adults. The receipts for admission totaled $528.75. How many children and how many adults swam at the public pool that day?
The number of children is 123 and the number of adults is 150 for that day.
According to the question,
We have the following information:
273 people used the public swimming pool.
Price for children = $1.25
Price for adults = $2.50
The total amount received = $528.75
Now, let's take the number of children to be x and the number of adults to be y on that day.
So, we have the following expression:
x + y = 273
x = (273-y) .... (1)
1.25x + 2.50y = 528.75
Now, putting the value of x from equation 1:
1.25(273-y) + 2.50y = 528.75
341.25 - 1.25y + 2.50y = 528.75
341.25 + 1.25y = 528.75
1.25y = 528.75-341.25
1.25y = 187.5
y = 187.5/1.25
y = 150
Now, putting this value of y in equation 1, we will find the value of x:
x = 273-y
x = 273-150
x = 123
Hence, the number of children is 123 and the number of adults is 150 on that particular day.
