Use finite differences to identify the degree of the polynomial that best describes the data.
Answers
Answer:
cubic
Step-by-step explanation:
The degree of the polynomial that best describes the data is quadratic.
What is Polynomials?Polynomials are kind of algebraic expressions consisting of variables, constants and coefficients along with exponents consisting of finite number of terms.
There are different types of polynomials like linear, quadratic, cubic and so on depending on the highest degree of the variables.
Finite difference method is used to find the degree of the polynomial by finding the difference of the values corresponding to the the values of the independent variable which are equally spaced.
Here, x is the independent variable and the values of x are given.
We have,
x : -3 -1 1 3 5 7
y : 4 6 1 -11 -30 -56
Find the first finite difference of the y values, we get,
x : -3 -1 1 3 5 7
y : 4 6 1 -11 -30 -56
First finite difference : 2 -5 -12 -19 -26
This is not constant.
Second finite difference : -7 -7 -7 -7
Second finite difference is constant.
So this is a polynomial equation of degree 2.
Hence the given polynomial is quadratic.

What is Translation?Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.
A transformation known as a translation involves moving each point in a figure uniformly and in the same direction.
Given:
Triangle DEF is reflected over the y-axis to form triangle D'E'F'.
now, we have the rule for reflection over y axis
P( x, y)-----> P' (-x, y)
Then the coordinates of D'E'F are
D(4, 1)---------> D'(-4, 1)
E(8, -3)---------> E'(-8, -3)
F (6, -4)----------> F'(-6, -4).

Answer:
The value of x is 1
Step-by-step explanation:
Let us solve the question
∵ Δ PQR ≈ Δ FGH
→ From similarity, then their corresponding sides have an equal ratio
∴ [tex]\frac{PQ}{FG}[/tex] = [tex]\frac{QR}{GH}[/tex] = [tex]\frac{PR}{FH}[/tex]
∵ PQ = 3, QR = x + 3, PR = 2
∵ FG = 6, GH = 6x + 2, FH = 4
→ Substitute them in the ratios above
∴ [tex]\frac{3}{6}[/tex] = [tex]\frac{x+3}{6x+2}[/tex] = [tex]\frac{2}{4}[/tex]
→ By using cross multiplication between the first two ratios
∵ 3 × (6x + 2) = 6 × (x + 3)
∴ 3(6x + 2) = 6(x + 3)
∴ 3(6x) + 3(2) = 6(x) + 6(3)
∴ 18x + 6 = 6x + 18
→ Subtract 6x from both sides
∵ 18x - 6x + 6 = 6x - 6x + 18
∴ 12x + 6 = 18
→ Subtract 6 from both sides
∵ 12x + 6 - 6 = 18 - 6
∴ 12x = 12
→ Divide both sides by 12
∴ x = 1

work out an estimate for sqrt 63.6 x 102.3
Answers
Answer:
81
Step-by-step explanation:
Round 63.6 to 64
Round 102.3 to 102
Multiply 64 × 102=6528
Square root 6528 to get 80.796
Round 80.796 to 81
The estimate square root value of 63.6 x 102.3 is 81
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 equation be A
The value of A is
A = square root of 63.6 x 102.3
A = √63.6 x 102.3
Now , the value 63.6 can be approximated as 64
And the value 102.3 can be approximated as 102
So , the equation becomes
A = √ ( 64 x 102 )
A = 8 x √102
A = 8 x 10.099
A = 80.79
The value of A can be approximated as
A ≈ 81
Therefore , the value of A is 81
Hence , The estimate square root value of 63.6 x 102.3 is 81

PART 1
1) BC = AD = 16.4
2) CD = AB = 13.9
because JKMN is a parallelogram
=> KJ = ML
<=> y + 3 = 2y - 1
<=> y = 4
we also have: KL = JM
<=> 3x + 5 = 4x
<=> x= 5
3) with y = 4 => JK = 4 + 3 = 7
4) with x = 5 => KL = 3.5 + 5 = 20
PART 2
5) W = Y = 112⁰
6) Z = 180⁰ - 112⁰ = 68⁰
ABCD is a parallelogram
=> A + B = 180⁰
<=> 2y + 4y = 180
<=> y = 30
we also have:
C + D = 180⁰
<=> x + 5x - 180 = 180
=> x = 60
7) with y = 30 => A = 2.30 = 60⁰
8) with x = 60 => D = 5.60 - 180 = 120⁰
PART 3
9) EG = 2.HG = 2.14 = 28
10) DH = 1/2.DF = 20/ 2 = 10
QRSP is a parallelogram

x + 9 = 2y
