Data Set I is multiplicative because
x y
------------
0×2 = 0
1×2 = 2
2×2 = 4
etc.
Data Set II is additive because
x y
--------------
0+2 = 2
1+2 = 3
2+2 = 4
etc.
Answer: C
Step-by-step explanation: Hi there.
To answer this question, we need to look closely at the data tables and answers.
A cannot be right. If the relationship is additive, that means that an input x is being added to a number to get a certain number y. If the relationship is multiplicative, that means an input x is being multiplied by number to get a certain number y. The relationship cannot be additive if the input is being multiplied (and vice versa) because it does not make sense.
B cannot be right. (See A for reason)
D cannot be right. (See A for reason)
C is right. It states that Data Set I is multiplicative because y is 2 times x, and the relationship for Data Set II is additive because y is two more than x. Every x value in Data Set I is being multiplied by 2 to get y (just divide y by 2 to check), and every x value in Data Set II has 2 added to it to get y (just subtract y by 2 to check). It also gets it right that Data Set I is multiplicative and Data Set II is additive.

1) Simplify the expression. –2x(1–3x) + (2x + 3)(3x – 2)
Make sure you show all your work for full credit. Use standard polynomial format.
Answers
Answer:
12x² + 3x - 6
Step-by-step explanation: -2x(1-3x) = -2x+6x²
(2x+3)(3x-2), first do 2x
2x × 3x = 6x²
then 2x × -2= -4x
we then move to the number 3
3 × 3x = 9x
3 × -2 = -6
after that we add them together
-2x + 6x² + 6x² - 4x +9x - 6 = 6x² + 6x² is 12x², -2x - 4x + 9x = 3x, and then -6 is by its self
= 12x² + 3x - 6
The simplified solution of the expression is 6x²- 4x - 6.
What is an expression?In mathematics, an expression is a combination of one or more numbers, variables, and/or operators that can be evaluated to obtain a value. Expressions can be as simple as a single variable or number, or as complex as a combination of variables, numbers, and mathematical operations.
We can simplify the expression by distributing the terms and combining like terms:
E = -2x(1 - 3x) + (2x + 3)(3x - 2)
E = -2x + 6x² + (6x - 4x - 6)
E = 6x² - 4x - 6
Therefore, the simplified expression is 6x²- 4x - 6.

Step-by-step explanation:
You can break the entire figure into two semi-circles, two triangles, and a rectangle.
The area of a semi-circle is 1/2 the area of a full circle. The area of a circle is πr^2. The area of the semi-circle is therefore:
[tex]\pi r^2/2=\pi (10^2)/2=50\pi[/tex]
The other semi-circle also contributes a value of 50π.
Moving on to the triangle, we must use Pythagorean's Theorem to find the value of the base:
[tex]a^2+b^2=c^2[/tex]
[tex]11^2+b^2=20^2[/tex]
[tex]121+b^2=400[/tex]
[tex]b^2=279[/tex]
[tex]b=\sqrt{279}[/tex]
The area of a triangle is:
[tex]Area=b*h/2[/tex]
[tex]A=(\sqrt{279} *11)/2[/tex]
The other triangle also contributes the same area.
Finally, the rectangle. To find the length of the rectangle, we must subtract the base of the triangle from 22. The length is:
[tex]l=22-\sqrt{279}[/tex]
The area of a rectangle is:
[tex]Area=l*w[/tex]
[tex]A=(22-\sqrt{279} )*(11)[/tex]
The total area of the figure is:
[tex]Area=2*(50\pi) +2*(\sqrt{279} *11/2)+11*(22-\sqrt{279} )[/tex]
[tex]Area=100\pi +11*\sqrt{279} +11*(22-\sqrt{279} )[/tex]
[tex]Area=100\pi +242[/tex]
[tex]Area=556.2[/tex]
Answer:
556.2 unit square
Step-by-step explanation:
Solution given:
Area of left semi circle= ½*πr²
where r is radiussince diameter is given 20.
so radius =diameter/2=20/2=10
substituting value
Area of left semi circle =½*π*10²=50π unit square
Since
Right semi circle's diameter is same as left semi circle
so
it's area will also be same.
Area of right semi circle= 50π unit square
Again
Area of middle rhombus= base* height
where base=22 and height is 11
substituting value
Area of middle rhombus=22*11 =242 square units
Now
Total Area=Area of left semi circle+Area of right semi circle+ Area of middle rhombus
Total Area= 50π+50π+242=556.159 unit square in nearest 10 is 556.2 unit square

Enter your numerical answer in the box, do not include words or spaces.
Answers
Answer:
6 units
Step-by-step explanation:
Given the following question:
Point A = (-4, 3) = (x, y)
Point B = (-4, -3) = (x, y)
To find the distance between the following points we must first plot the points on the coordinate plane.
Point A: Move over to the left four times, move up three times.
Point B: Move over to the left four times, move down three times.
The distance between the two points given is "six units." Since the x values are the same, and the y values are opposites from each other doubling their distance by two.
Hope this helps.

Convert the angle - 3 radians to degrees, rounding to the nearest 10th.
Answers
Answer:
formula :
-3rad × 180/π = -171.9°
Step-by-step explanation:
hope that help's you :))!!
The measure of the angle in degrees is A = -171.9°
What is Central Angle?The central angle is an angle with two arms and a vertex in the middle of a circle. The two arms of the circle's two radii intersect the circle's arc at two separate locations. It is an angle whose vertex is the center of a circle with the two radii lines as its arms, that intersect at two different points on the circle.
The central angle of a circle formula is as follows.
Central Angle = ( s x 360° ) / 2πr
where s is the length of the arc
r is the radius of the circle
Central Angle = 2 x Angle in other segment
Given data ,
Let the measure of the angle be A = -3°
Now , angle in degrees = angle in radians × 180°/π
Substituting the given value, we get:
The angle in degrees = (-3) × 180°/π
On simplifying the equation , we get
A = -171.8873385°
On rounding to the nearest tenth , we get
A = -171.9°
Hence , the angle is A = -171.9°
