2. You transfer into a college with 60 credits. How long will it take you to graduate if you can only take 8
credits per semester? The number of credits needed to graduate is 128. Write an equation for the
number of credits, C, accumulated as a function of the number of semesters, t, at the college.
the function as 17 / 2 = C t for the data given.
Credits we have = 60
credits needed to graduate = 128
Credits in 1 semester = 8
Let the number of semesters be t
Number of credits = C
So, we get the function as:
128 = 60 + 8 C t
128 - 60 = 8 C t
68 = 8 C t
17 / 2 = C t
Therefore, we get that, the function as 17 / 2 = C t for the data given.

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

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.

Find the perimeter and the area of ABCD with vertices A(3, 5), B(6, 5), C(4, -1), and D(1, -1). Round your answer to the nearest hundredth place, if necessary. Perimeter: Area: units square units
The perimeter of the shape is determined as 19.91 units and the area is 20.87 sq. units.
What is perimeter?
The perimeter of an object or a shape is the distance around the edge of the shape.
Length of AB = √[(6 - 3)² + (5 - 5)²] = 3 units
Length of AC = √[(4 - 3)² + (-1 - 5)²] = 6.1 units
Length BD = √[(6 - 1)² + (5 - -1)²] = 7.81 units
Length CD = √[(1 - 4)² + (-1 - -1)²] = 3 units
Perimeter of the shape ABCD = 3 units + 6.1 units + 7.81 units + 3 units = 19.91 units.
Area of the shapeThe formula for area of a trapezoid will be used to determine the area of the shape as shown below;
A = ¹/₂(6.1 + 7.81) x 3
A = 20.87 sq. units
Thus, the perimeter of the shape is determined as 19.91 units and the area is 20.87 sq. units.

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 }

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.

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

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 ...
