Answer= 0
Step-by-step explanation:
Give the first four terms of the arithmetic sequence
for which a₁ = 12 and d = -2.
A 12, 10, 8, 6
B 12, -24, 48, -96
C 12, 14, 16, 18
D 10, 8, 6, 4
An arithmetic sequence is a sequence of numbers which will have a constant common difference throughout the sequence.
The first term of the sequence is given as a₁ = 12 and
The common difference of the sequence is given as d = -2
We need to find the first four terms of the arithmetic sequence
So, the formula to find the first four terms of an arithmetic sequence is
a, a+d , a+2d, a +3d...
where a = 12
d = -2
Then, the arithmetic sequence of the first four-term is
= 12,12 + (-2) , 12 + 2(-2) , 12 + 3 (-2)
= 12 , 12-2 , 12 -4 , 12 - 6
= 12 , 10 , 8 , 6
So the arithmetic sequence of the first four-term is
12,10,8,6.

Answer:
(c) (-30)⁴
Step-by-step explanation:
You want to simplify the product (-6)⁴×(5)⁴.
ExponentsAn exponent is an indicator of repeated multiplication:
(-6)⁴ = (-6)(-6)(-6)(-6) . . . . . . the factor -6 is repeated 4 times
(5)⁴ = (5)(5)(5)(5)
Then the product is ...
(-6)⁴ × (5)⁴ = (-6)(-6)(-6)(-6)(5)(5)(5)(5)
The commutative and associative properties of multiplication let you regroup this to ...
(-6)(5)×(-6)(5)×(-6)(5)×(-6)(5) = (-30)(-30)(-30)(-30)
Using the exponent to signify repeated multiplication, this can be written as the equivalent ...

A coach asked her athletes if they enjoy running. Forty-five percent of the team do not like to run. Of those, 70% enjoy cycling, while 80% of those who enjoy running also enjoy cycling. The tree diagram shows how the athletes are divided into subgroups.
a tree diagram shows athletes branching off into two categories of enjoys running and does not enjoy running. Enjoys running branches off into two sub-categories of enjoys cycling and does not enjoy cycling. Does not enjoy running branches off into two sub-categories of enjoys cycling and does not enjoy cycling
What is the total percentage of the athletes who do not enjoy cycling?
50%
24.5%
13.5%
11%
Using proportions, the total percentage of the athletes who do not enjoy cycling is: 24.5%.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For this problem, the proportions of people who do not like cycling are:
0.30 of 0.45(do not like to run).0.2 of 0.55(enjoy running).Hence the total proportion is:
0.3 x 0.45 + 0.2 x 0.55 = 0.245.
Multiplying by 100% to convert from proportion to percentage, 24.5% of the athletes who do not enjoy cycling.

After plotting the line of the best fit, the estimated values of a and b are
(30,1.15) and the equation is M = 30L ₊ 1.15
Given, the values of L and M are plotted on the graph.
Then the line of best fit is created on the graph.
A line that most accurately depicts the relationship between data points on a scatter plot is called the line of best fit.
When data points appear to be in a straight line, the line of greatest fit is a straight line.
Therefore, we get the point on the line as (30,1.15)
The equation representing the relation:
M = aL + b
(a,b) from the graph is (30,1.15)
substitute the estimated the values,
M = 30L + 1.15
Hence the required values are estimated and plotted on the graph.

5. What is the domain of the function y = 3x - 4 when the range is (-7, 2, 8, 14}?

Y = 3x-4
B.
{-1, 2, 4, 6}
C. {-25, -29, -33, -37}
D. (17, 21, 25, 29}
4413
the domain will be D = { - 1 , 2 , 4 , 6 } for the function y = 3 x - 4.
We are given a function:
y = 3 x - 4
Now we are also given the range as:
R = { -7 , 2 , 8 , 14 }
For y = - 7, we get the value of x as:
- 7 = 3 x - 4
3 x = - 7 + 4
3 x = - 3
x = - 3 / 3
x = - 1
For y = - 2, we get the value of x as:
2 = 3 x - 4
3 x = 2 + 4
3 x = 6
x = 6 / 3
x = 2
For y = 8, we get the value of x as:
8 = 3 x - 4
3 x = 8 + 4
3 x = 12
x = 12 / 3
x = 4
For y = 14, we get the value of x as:
12 = 3 x - 4
3 x = 14 + 4
3 x = 18
x = 18 / 3
x = 6
So, the domain will be:
D = { - 1 , 2 , 4 , 6 }
Therefore, the domain will be D = { - 1 , 2 , 4 , 6 } for the function y = 3 x - 4.

Find the perimeter of triangle ABC with vertices A(1,-6), B(1,-3), and C(-4,-6). Round to the nearest hundredth if necessary
The perimeter of triangle ABC is equal to 13.83.
PerimeterThe perimeter of a geometric figure is the sum of its sides. Thus, for a triangle, for example, the perimeter is S1+S2+S3, where S represents the dimension of each side.
Given Data
Coordinates Points: A(1,-6), B(1,-3), and C(-4,-6)TriangleIn this question are given the coordinates of each vertex triangle. Then, you should plot these coordinates A(1,-6), B(1,-3), and C(-4,-6) in a graph. See the attached image.
From the plotted points, it is possible to note that the triangle is a right triangle and its sides are: AB=3 and AC=5. For finding the side BC, it is necessary to apply the Pythagorean Theorem: (hypotenuse)²= (side1)²+(side2)². Thus,
(hypotenuse)²= (side1)²+(side2)²
(BC)²=(AB)²+(AC)²
(BC)²=(3)²+(5)²
(BC)²=9+25
(BC)²=34
BC=[tex]\sqrt{34}[/tex]=5.83
Now, you have all information to calculate the perimeter of the given triangle.
perimeter = AB+AC+BC = 3 +5 +5.83 =8+5.83=13.83

Find the other endpoint of the segment with a
midpoint of (-6, 4) and endpoint of (4, 8).
Answer:
(-16, 0)
Step-by-step explanation:
You want the other endpoint of the segment with midpoint (-6, 4) and endpoint (4, 8).
SetupThe midpoint of a line segment has coordinates that are the average of the coordinates of the end points.
M = (A +B)/2 . . . . midpoint M of segment AB
2M = A +B . . . . . multiply by 2
B = 2M -A . . . . . solved for the other end point
B = 2(-6, 4) -(4, 8) . . . . substitute given coordinates
SolutionB = (2(-6) -4, 2(4) -8) = (-16, 0)
The other end point of the segment is (-16, 0).
