Answer:
Radians are used to measure angles. ... A 360 degree angle is the same as a 2pi radian angle. Radians start being used in geometry and trig as you start using the unit circle. I think marking them in the unit circle is a good way to visualize how they work, and how they can be a good unit to work with in that context.
Step-by-step explanation:
mark me big brain
Answer:a radian is a angle made by taking the radius and wrapping it round the circle and
they relate to degrees because Degrees measure angles by how far we tilted our heads. ... or angle in radians

is this a slope of 8/4
Answer:
Yes
Step-by-step explanation:
Write an equation of the line that passes through (0, 4) and (0, -3)
Answer: Slope is undefined. x=0
slope calculation: -3-4/0-0 = -7/0 and anything divided by 0 is undefined
the x value in the coordinates is 0 so it’s x=0 line.
vertical lines always have undefined slopes
Answer:
[tex]x=0[/tex]
Step-by-step explanation:
So first of all we need the slope of the line we are trying to findWe get the slope by using the following formula [tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex] So when you have two pairs of points, it will be [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] so our points are; (0,4) the first point, so [tex]x_1=0,y_1=4[/tex] and(0.-3) the second point, so [tex]x_2=0,y_2=-3[/tex] Put this in our equation [tex]slope=\frac{(-3)-(4)}{(0)-(0)}=\frac{-7}{0}[/tex] Oh no, that can't be right, any number divided by zero is undefined, meaning can't be answered. So this line has no slope So how do we know the equation? Remember, (a) if the line is horizontal, then the slope is 0,(b) if the line is vertical then the slope is undefinedSo our line is vertical, meaning it is an equation of xIf it were horizontal it would be an equation of ySo vertical, it is [tex]x=??[/tex] How do we know what x equals? Just look at our points (0,4) and (0,-3)For both of them [tex]x=0[/tex] and this is our equation!2. Write a function of the geometric sequence with a starting term of 10 and a common ratio of 4. Find the fourth term.

f(n) = 4.10^-1, the fourth term is 64 DI

How do you do this
I don’t get it
Answer:
x= 65 z= 38 y= 77
Step-by-step explanation:
x=65° (opposite angles are equal)
z= 180°-[71+71 (bc the other side is also equal to 71)]
z= 180°-142°=38°
y= 180 - [sum of angle x (65°) and angle z (38°)]
y= 180 - 103= 77°
to make sure ur answer is correct the sum of angle x, y and z MUST = 180
lets check:
65° + 38° + 77° = 180°

Five is the quotient of 120 divided by some number. What is the number? 20 24 115 125
Your answer is 24! If you work backwards and divide 120 by 5, you get 24. To check your work, multiply 24 by 5 to get 120. Hope this helps! Please mark brainliest and have an amazing rest of your day. Stay safe! xx
The number 24 divides 120 gives the Quotient 5.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Quotient = 5
Dividend = 120
Divisor = x
So, Dividend = Divisor . Quotient
120 = x(5)
5x = 120
x= 120/5
x= 24.
Thus, the required number is 24.

what coefficient would you get for the x terms on the right side of 3x+15=2x+10+x+5
Answer:
x=0
Step-by-step explanation:
Answer:
Any real number.
Step-by-step explanation:
3x + 15 = 2x + 10 + x + 5
First, add like terms.
3x + 15 = 3x + 15
Subtract 15 on both sides.
3x = 3x
Divide 3 on both sides.
x = x
Since x equals x, you can give any value (any real number) to x.
Since 3x = 3x, you can say x = 1, meaning 3 = 3.
Or, you can say x = 8. 3x = 3x will be 24 = 24.
x can be any number.

Answer:
b.
m<1 = 80 degrees because of the alternate angles rule.
m<2 = 100 degrees because angles on a straight line equals 180 degrees.
c.
m<1=75 degrees because again of the alternate angle rule.
m<2= 60 because that angle is equal to diagonally upper angle (I'll call it Z) and that angle would equal 60 because 180-120=60

Mai thinks of a secret number. She says that her secret number is more than 11 units away from 50. Write an absolute- value inequality that gives the possible values of Mai's number.
Given:
Secret number is more than 11 units away from 50.
To find:
The absolute- value inequality that gives the possible values of Mai's number.
Solution:
Let the secret number be x.
Secret number is more than 11 units away from 50. It may be less than 50 or more than 50.
Case 1: If x<50, then [tex]50-x>11[/tex]
Case 2: If x>50, then [tex]x-50>11[/tex]
It means the absolute difference between secret number and 50 is greater than 11.
[tex]|x-50|>11[/tex]
Therefore, the required inequality is [tex]|x-50|>11[/tex].
is y=-2/5x inverse or direct variation
Answer:
direct
Step-by-step explanation:
The standard form of an equation representing direct variation is
y = kx ← k is the constant of variation
The standard form of an equation representing inverse variation is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
y = - [tex]\frac{2}{5}[/tex] x ← represents direct variation with k = - [tex]\frac{2}{5}[/tex]
