hi anyone can help me ??
Answer:
Step-by-step explanation:
a) The name of the figure is a pentagon.
b) You need to find <HBA. Before you can do that, you need to get the interor angle of 43 and 104
EAF = 180 - 43
EAF = 137
HCD = 180 - 52 = 128
CDE = 180 - 104
CDE = 76
Now you can get <HBA = 540 - 76 - 137 - 90 - 128 = 540 - 431 = 109
x = 180 - 109 = 71
Let v = (v1, v2) be a vector in R2. Show that (v2, −v1) is orthogonal to v, and use this fact to find two unit vectors orthogonal to the given vector.
v = (21, 20)
Answer:
a. v.v' = v₁v₂ - v₁v₂ = 0 b. (20, -21)/29 and (-20,21)/29
Step-by-step explanation:
a. For two vectors a, b to be orthogonal, their dot product is zero. That is a.b = 0.
Given v = (v₁, v₂) = v₁i + v₂j and v' = (v₂, -v₁) = v₂i - v₁j, we need to show that v.v' = 0
So, v.v' = (v₁i + v₂j).(v₂i - v₁j)
= v₁i.v₂i + v₁i.(- v₁j) + v₂j.v₂i + v₂j.(- v₁j)
= v₁v₂i.i - v₁v₁i.j + v₂v₂j.i - v₂v₁j.j
i.i = 1, i.j = 0, j.i = 0 and j.j = 1
So, v.v' = v₁v₂i.i - v₁v₁i.j + v₂v₂j.i - v₂v₁j.j
= v₁v₂ × 1 - v₁v₁ × 0 + v₂v₂ × 0 - v₂v₁ × 1
= v₁v₂ - v₂v₁
= v₁v₂ - v₁v₂ = 0
So, v.v' = 0
b. Now a vector orthogonal to the vector v = (21,20) is v' = (20,-21).
So the first unit vector is thus a = v'/║v'║ = (20, -21)/√[20² + (-21)²] = (20, -21)/√[400 + 441] = (20, -21)/√841 = (20, -21)/29.
A unit vector perpendicular to a and parallel to v is b = (-21, -20)/29. Another unit vector perpendicular to b, parallel to a and perpendicular to v is thus a' = (-20,-(-21))/29 = (-20,21)/29

A researcher believes that working out in colder temperatures will burn more calories because a person has to burn more calories to keep warm. The researcher decides to study various groups of people working out at different temperatures and measure their progress. How would you describe the temperature in the study?
A Observational
B Experimental
C Census
D Simulation
Answer:
B. Experimental
Step-by-step explanation:
The only way to properly study this would be by using an experimental study. The researcher would need to create different groups and place them in different temperature conditions but keeping all of the other variables in the study the same while they exercise. Then gather as much data as possible including weight, calorie consumption, body temperature, etc. Finally, analyze the data and come to a conclusion. The other types of studies will not allow the researcher to gather the necessary data to come to a proper conclusion.

What is this math question? Yesterday Nathan rode his bike 39 kilometers in 3 hours. Today Nathan rode his bike 8 kilometers in 30 minutes. Compare his rates for those two days. Show your work.
Answer:
Comparing Nathan's rate for the two days, Nathan's speed(rate)/was faster today than yesterday
Step-by-step explanation:
Yesterday Nathan rode his bike 39 kilometers in 3 hours.
Today Nathan rode his bike 8 kilometers in 30 minutes. Compare his rates for those two days. Show your work.
Speed /rate =>Distance(km)/ Time(hr)
For yesterday
Speed = 39km/3 hour
Speed = 13 km/hr
For Today
Convert time in minutes to hour
60 minutes = 1 hour
30 minutes = x hour
= 30/60
= 0.5 hour
Speed=> 8km/ 0.5 hour
=16 km/hr
Comparing Nathan's rate for the two days, Nathan's speed(rate)/was faster today than yesterday

What is the solution to
6(2 - x)<-4x + 2?
Answer:
Solving [tex]6(2 - x)<-4x + 2[/tex] we get [tex]\mathbf{x>5}[/tex]
Step-by-step explanation:
We need to find solution of [tex]6(2 - x)<-4x + 2[/tex]
Solving the inequality:
[tex]6(2 - x)<-4x + 2[/tex]
Multiply 6 with terms inside the bracket
[tex]12-6x<-4x+2[/tex]
Subtracting 12 on both sides
[tex]12-6x-12<-4x+2-12\\-6x<-4x-10[/tex]
Adding 4x on both sides
[tex]-6x+4x<-4x-10+4x\\-2x<-10[/tex]
Divide both sides by -2 and the inequality will be reversed i.e < will be changes to >
[tex]\frac{-2x}{-2}>\frac{-10}{-2}\\\mathbf{x>5}[/tex]
So, after solving [tex]6(2 - x)<-4x + 2[/tex] we get [tex]\mathbf{x>5}[/tex]
Jane is cooking in her recipe indicates that she should add several spices she needs to add 1/2 of a teaspoon of salt, 1 1/4 teaspoons of Orégano 3/4 of a teaspoon of basil in half as much pepper as salt. What is the total number of teaspoons of spices in the dish express the answer as a decimal
Answer: total number of teaspoons of spices in the dish =3.25 teaspoons
Step-by-step explanation:
Step 1
Listing the spices and their quantities , we have
Salt = 1/2 teaspoon
Orégano =1 1/4 teaspoon =5/4 teaspoons
Basil = 3/4 teaspoon
Pepper= in half as much pepper as salt -- This means that the quantity of pepper should be 50% more in quantity than salt
Therefore quantity of pepper = 50% x 1/2 = 0.5 x 0.5= 0.25
0.25 + 1/2 = 0.25 + 0.5 = 0.75 = 3/4 teaspoon of pepper.
Step 2
Adding the amount of spices we have
1/2 + 5/4+ 3/4+ 3/4 = 2+ 5+3+ 3/4 = 13/4 = 3 1/4 teaspoons of spices = 3.25 teaspoons of spices .
a recipe for trail mix calls for 50 grams of almonds for every 2 cups of oats. the line represents the relationship between the amount of almonds and the amount of oats needed to make trail mix according to this recipe. the point (1, 25) is on theine. what is the equation for this line? use the format y=kx
Answer:
The equation is: y=25x
Step-by-step explanation:
Linear Modeling
When two variables have a linear dependency, the relationship between them can be written as:
y=kx+b
Where k is the slope and b is the y-intercept. When b=0, then the relationship is called proportional, and the equation is:
y=k.x
For the question, we call y=grams of almond and x=cups of oats.
It's given for x=cups of oats, the recipe for trail mix calls for y=50 grams of almonds. Substituting into the equation:
50=k.2
Solving for k:
k=50/2=25
The final equation is:
y=25x
Note the point (1,25) is on the line, as required.

For 4-6, determine whether the three numbers could be the lengths of the sides of a
triangle.
4. 4, 8, 11
5. 6, 12,5
6. 13, 13, 26
Answer:
4. 4, 8, 11 could be the lengths of the sides of a triangle
5. 6, 12, 5 could not be the lengths of the sides of a triangle
6. 13, 13, 26 could not be the lengths of the sides of a triangle
Step-by-step explanation:
There is an important rule about the sides of the triangle
The sum of lengths of the smallest two sides of a triangle must be greater than the length of the third sideLet us use this rule to solve questions 4, 5, and 6
#4.
∵ The numbers are 4, 8, 11
∵ The two smallest numbers are 4, 8
∵ Their sum = 4 + 8 = 12
∵ The greatest number is 11
∵ 12 > 11
∴ The sum of the two smallest number is greater than the third number
∴ The numbers could be the length of the sides of a triangle
∴ 4, 8, 11 could be the lengths of the sides of a triangle
#5.
∵ The numbers are 6, 12, 5
∵ The two smallest numbers are 5, 6
∵ Their sum = 5 + 6 = 11
∵ The greatest number is 12
∵ 11 < 12
∴ The sum of the two smallest number is smaller than the third number
∴ The numbers could not be the length of the sides of a triangle
∴ 6, 12, 5 could not be the lengths of the sides of a triangle
#6.
∵ The numbers are 13, 13, 26
∵ The two smallest numbers are 13, 13
∵ Their sum = 13 + 13 = 26
∵ The greatest number is 26
∵ 26 = 26
∴ The sum of the two smallest number is equal to the third number
∴ The numbers could not be the length of the sides of a triangle
∴ 13, 13, 26 could not be the lengths of the sides of a triangle
