Given:
The figure of a circle.
To find:
The measure of arc AD and measure of each arc.
Solution:
The measure of arc is equal to the central angle of that arc.
The central angle of arc AD is 105 degrees. So,
[tex]m(arc(AD))=105^\circ[/tex]
The central angle of arc BC is 35 degrees. So,
[tex]m(arc(BC))=35^\circ[/tex]
The central angle of arc CD is 50 degrees. So,
[tex]m(arc(CD))=50^\circ[/tex]
The central angle of a complete circle is 360 degrees. So,
[tex]m(arc(AD))+m(arc(BC))+m(arc(CD))+m(arc(AB))=360^\circ[/tex]
[tex]105^\circ+35^\circ+50^\circ+m(arc(AB))=360^\circ[/tex]
[tex]190^\circ+m(arc(AB))=360^\circ[/tex]
[tex]m(arc(AB))=360^\circ-190^\circ[/tex]
[tex]m(arc(AB))=170^\circ[/tex]
Therefore, the measure of arc AD is 105°, the measure of arc BC is 35°, the measure of arc CD is 50° and the measure of arc AB is 170°

were in the jar at the start of the first day?
Answers
Answer:
At the beginning of the first day there were 75 pistachios in the jar.
Step-by-step explanation:
Given that each day, Robert eats 40% of the pistachios left in his jar at that time, and at the end of the second day, 27 pistachios remain, to determine how many pistachios were in the jar at the start of the first day you must perform the following calculations:
100 - 40 = 60
60 = 27
100 = X
100 x 27/60 = X
2700/60 = X
45 = X
60 = 45
100 = X
100 x 45/60 = X
4500/60 = X
75 = X
Therefore, at the beginning of the first day there were 75 pistachios in the jar.

Which equation has a graph that is a parabola with a vertex at (-2, 0)?
O y=-22²
O y = (x + 2)2
O y = (x - 2)2
Oy=x²-2
Answers
Answer: y = (x+2)^2
Aka: B
Step-by-step explanation:
Did it on edge just now !
The equation y = (x + 2)² has a graph that is a parabola with a vertex at
(-2, 0).
Option B is the correct answer.
What is a parabola?A parabola is an equation of a curve, such that any point on the curve is equidistant from a fixed point called the focus and a fixed line called the directrix of the parabola.
The equation of a parabola:
y = a(x-h)^2 + k
We have,
The equation that has a graph that is a parabola with a vertex at (-2, 0) is
y = (x + 2)².
The general equation for a parabola is y = a(x - h)² + k, where (h, k) is the vertex of the parabola.
Comparing this general equation to y = (x + 2)²,
We can see that h = -2 and k = 0, which means that the vertex of the parabola is (-2, 0).
Therefore,
The equation y = (x + 2)² has a graph that is a parabola with a vertex at
(-2, 0).

What is the recursive rule for the sequence? -1,-0.5,0,0.5,1,...
Answers
9514 1404 393
Answer:
C
Step-by-step explanation:
The subscript (n-1) is used to indicate the term previous to term (n). In this sequence, each term is 0.5 more than the previous term, so the recursive relation ...
[tex]a_n=a_{n-1}+0.5[/tex]
is the appropriate one. This matches choice C.
__
Additional comment
Of course, if the next term is 0.5 more than the last, then the previous term is 0.5 less than the present one. The sequence can be described in this "backward" fashion by the recursive relation of choice A. While that does work to describe the sequence, it is usually not the form we desire for a recursive relation.

The sum of three consecutive numbers is 72. What is the smallest of these numbers? Set up an equation to solve.
Answers
Answer:
Let the three consecutive numbers be x,x+1,x+2 . The numbers are: 23,24,and25 and the smallest one is 23
Step-by-step explanation:
Answer: (x-1) + (x) + (x+1) = 72; smallest number is 23.
Step-by-step explanation:
The numbers are consecutive, meaning they sit next to each other on a number line. For example 4, 5, 6.
Because they are three consecutive numbers, their average will be the value of the middle one. For example the average of 4, 5, 6 is 5.
Knowing this, we can divide 72 by three to get the value of the middle number.
72/3 = 24, so the middle number is 24.
The numbers that fall either side of 24 on the number line are 23 and 25, so the three consecutive numbers are 23, 24, 25.
You can also set up and solve the equation: (x-1) + (x) + (x+1) = 72 because the numbers are consecutive.
To solve, combine like terms. The (-1) and (+1) cancel out and the equation becomes 3x = 72.
72/3 = 24, so x = 24, and the smallest term, (x-1) = 23.

Answer:
A. the control group in an experiment
Step-by-step explanation:
Researchers give one group a new cold medicine and compare them with to a group that takes no medicine. The group that is not given any medicine is the control group in an experiment.
Who are researchers?Researchers are those who do research on something i.e. systematics and deep investigation into something.
What is control group?Control Group is that group in research which does not take any medication or untreated group.
During the research while a new type of medicine is to be tested, the group that receives the medication or being tested is called the experimented group and the group that does not receive the treatment is called the control group.
Hence, we can say that the group that is not given any medicine is the control group in an experiment.

Answer:
Length = 12 feet, Width = 10 feet
Step-by-step explanation:
Let the length of the bedroom be 'x' ft and the width of the bedroom be 'y' ft.
We know that the perimeter of a rectangle is given by,
P=2(length+width)
P=2(x+y)
It is given that, the length of the bedroom is 2 more than the width, so,
x=y+2
Putting the values in the equation of perimeter we get,
44=2((y+2)+y)
44=2(2y+2)
44/2 =2y+2
22=2y+2
2y=22−2
y= 20/2 =10
Therefore, x=y+2=10+2=12
Hence, the length of the bedroom is 12 feet and the width of the bedroom is 10 feet.

Answers
Answer:
20%
Step-by-step explanation:
The formula to find percent error is the absolute value of the actual value (60) minus the approximate value (48) divided by the actual value (60) times 100. So first we calculate 60 - 48 which is 12 then divide 12 by 60 which gives us 0.2 and finally multiply by 100 which gives us the answer of 20%
