Answer:
Step-by-step explanation:
p1(-3,2) p2(2,6)
find the slope of the line between these two points
m= 6-2 /2-(-3)
m=4/5
find the slope of the line between p2 and p3(8,-1)
m=-1-6 /8-2
m=-7 / 6
dist= sqrt( (8-(-3))^2+(-1-2)^2)
dist = 11.40175 (1 to 3) hyp
dist = sqrt( (8-2)^2 + (-1-6)^2)
dist = 9.219544 (2 to 3)
dist = sqrt( (2-(-3))^2 + (6-2)^2)
dist = 6.403124 ( 1 to 2)
use law of cosines to find an angle
law of cosines cos(C) = (a^2+b^2-c^2) / (2ab) =97.61°
cos(A) = (b^2+c^2-a^2) / ( 2bc) = 32.23°
cos(B) = (a^2+c^2-b^2) / (2ac) =50.16°
do the same process as above but for the points in 23
This took me a few hours :/ granted I took a break for dinner but still .. pay me for that much work :D.. if you can't get 23 later re post question I'll work on it later

Step-by-step explanation:
A student observes a difference in the activity level of fish at a pet store. The fish in an aquarium near the window are swimming around more quickly tha the fish in an aquarium placed in the back of the store. The student forms a hypothesis about the effect of sunlight on fish activity levels and arranges to conduct an experiment. Which variable could be an independent variable in the student's experiment? types of fish sold speed of swimming fish amount of time fish were active temperature of water in fish tank
Answer: Types of fish sold
The type of fish sold is the independent variable in the student's experiment. So, the correct option is (A).
What are Variables?
A variable is any kind of characteristic, number, or quantity which can be measured or counted. It can also be called a data item. Examples of variables are age, sex, occupation income and expenses, country of birth, capital expenditure, class grade, eye color, and vehicle type.
There are two types of Variables are:
1. Dependent variable
A dependent variable is a type of variable which changes as the result of independent variable manipulation which is the outcome interested in measuring, and it "depends on" the independent variable.
2. Independent variable
An independent variable is the type of variable which is manipulated or varied in an experimental study in order to detect its effects. This is "independent" because it is not affected by any other variable in the study.
In above case, this is independent because types of fish characteristic is not dependent for the experiment.
Thus, the type of fish sold is the independent variable in the student's experiment. So, the correct option is (A).

What is the Mark the absolute minimum point of the graph
Answer:
is in the point x = 1, y = -5
Step-by-step explanation:
The absolute minimum of a graph is the point that is the most far below the x-axis.
Such that if we draw a horizontal line parallel to this point, this line should not intersect the graph in another point. It is usually associated with the lowest value of the variable y.
In the graph, we can see that in the extremes we have dots, so the graph does not continue.
Then we can be sure that the absolute minimum is at the bottom of the large curve, that is in the point x = 1, y = -5

What is the ratio of boys to girls in Mrs. Carlton's class, which has a total of 31 students, 14 of whom are girls?
Answer:
17:14 or 17 to 14
Step-by-step explanation:
since you know there are 14 girls, subtract 14 from 31 and then you'll get 17. since its asking for a ratio of boys to girls not girls to boys, you put boys first, then girls. so your answer will be 17:14

what are the areas for shape 1,2 and 3
Answer:
I think it is
1: 22.37
2:16.81
3:83.16
Step-by-step explanation:
Answer:
Shape 1: 22.365
Shape 2: 16.81
Shape 3: 83.16
Step-by-step explanation:
I'm going to start with 2, because its the easiest shape to do, which is 4.1*4.1= 16.81. Next is 3, which you find the length by adding 4.1 to 9.1 = 13.2. You then multiply 13.2 by 6.3 = 83.16. Finally for shape 1, you first find the bottom shape, which you do by dividing 6.3 by 2 so you can get the width of half the triangle. That is 3.15. then you multiply that by 7.1 to get the area of 22.365.

A group of friends wants to go to the amusement park. They have no more than $165
to spend on parking and admission. Parking is $5.25, and tickets cost $17.75 per
person, including tax. Write and solve an inequality which can be used to determine
X, the number of people who can go to the amusement park.
Inequality:
Answer:
17.75x + 5.25 [tex]\leq[/tex] 165
x [tex]\leq[/tex] 9
Step-by-step explanation:
The total cost can be represented by 17.75x + 5.25, where x is the number of people.
They can only spend a maximum of $165, so a less than or equal sign has to be used.
The inequality will be 17.75x + 5.25 [tex]\leq[/tex] 165
Now, solve for x:
17.75x + 5.25 [tex]\leq[/tex] 165
17.75x [tex]\leq[/tex] 159.75
x [tex]\leq[/tex] 9
So, x [tex]\leq[/tex] 9 is the answer, meaning 9 people or less can go to the amusement park.

m∠ABC=(6x+8)° and m∠DEF=(12x-8)°.
If ∠ABC and ∠DEF are supplementary,what
is the measure of each angle?
Answer:
m∠ABC = 68°
m∠DEF = 112°
Step-by-step explanation:
Supplementary angles are angles that add up to 180 degrees (they form a straight line).
If ∠ABC and ∠DEF are supplementary, that means that they add up to 180. We can write this in an equation:
(6x + 8) + (12x - 8) = 180Combine like terms.
18x = 180Divide both sides by 18.
x = 10Find the measure of each angle by substituting 10 for x into both expressions for the angles.
m∠ABC = (6x + 8)°
6(10) + 8 = 68°m∠DEF = (12x - 8)°
12(10) - 8 = 112°→ (6x + 8) + (12x - 8) = 180°
→ 6x + 8 + 12x - 8 = 180°
→ 18x = 180°
→ x = 180 ÷ 18
→ x = 10°
Now, we are given that m∠ABC = (6x+8) just subsitute the value of x in it .
→ m∠ABC = (6x + 8)
→ m∠ABC = (6 × 10 + 8)
→ m∠ABC = 60 + 8
→ m∠ABC = 68°
Similarly, subsitute the value of x in m∠DEF = (12x - 8)° we get :
→ m∠DEF = (12x - 8)°
→ m∠DEF = (12 × 10 - 8)
→ m∠DEF = 120 - 8
→ m∠DEF = 112°

Answer:
x = 1.8
Step-by-step explanation:
Given
2.5(10x - 16) = 5 ( divide both sides by 2.5 )
10x - 16 = 2 ( add 16 to both sides )
10x = 18 ( divide both sides by 10 )
x = 1.8
