Review the graph of a piece wise function.
At which value of x does the function have a jump discontinuity?
Answers
Given piecewise function has a jump discontinuity at 0 or x=0 i.e. B.
What exactly is a piecewise function?
A piecewise function is one that has multiple definitions in different x intervals. A piecewise function's graph is divided into parts that correspond to each of its definitions. A very excellent example of a piecewise function is the absolute value function. Let us investigate why it is thus named. We know that an absolute value function is defined as f(x) = |x|.
f(x)=(x if x≥0 ,
-x if x><0)
This piecewise function should be interpreted as
When x is higher than or equal to 0, f(x) equals x.
When x is less than zero, f(x) equals -x.
Now,
As jump discontinuity is defined as where the endpoint of one segment and the start of the following segment may have the same x coordinate but have different values of f(x). In the piecewise linear function, such a difference is known as a jump discontinuity.
and in the given graph that happened at x=0 or 0.
Hence,
Given piecewise function has a jump discontinuity at 0.

Note that using relationship 1 where
A = 50°; and
Y = 110°
Angle b = 70°; and
Angle c = 60°
This means that the triangle is a scalene triangle.
What is the rationale for the above response?Since a = 50° - Given; and
y = 110° - Given
to determine the m∠b, you must use the concept of sum of angles on a straight line. Sum of angles on a straight line must always equal 180°
Thus,
b = 180 - y
b = 180 - 110
b = 70°
To determine the m∠c, we used the sum of angles in a Δ theorem. This states that all angles in Δ must equal 180°
Since
a = 50° - Given; and
b = 70° - as derived above,
c = 180 - (a + b)
c = 180 - (50 + 70)
c = 180 - 120

Assume that we have two events, A and B; that are mutually exclusive Assume further that we know P(A) = 0.30 and P(B) = 0.70. If an amount zero, enter "0". What is P(AnB)? What is P(AIB)? student in statistics argues that the concepts of mutually exclusive events and independent events are really the same_ and that if events are mutually exclusive they must be independent; Do You agree with this statement? Use the probability information in this problem to justify your answer. Select your answer because P(AIB) Select your answer P(A). What genera conclusion would You make about mutually exclusive and independent events given the results of this problem?
Answers
P(A∩B) = 0 (the probability of both events occurring is zero).
P(A|B) = 0.
No. The student's argument that mutually exclusive events are independent is incorrect.
How to find P(AnB) and P(AIB) of the event?If events A and B are mutually exclusive, then by definition they cannot occur at the same time.
Thus, P(A∩B) = 0 (the probability of both events occurring is zero).
Since events A and B are mutually exclusive, they cannot be independent. In fact, if two events are mutually exclusive, it means that the occurrence of one event precludes the occurrence of the other event, so they are completely dependent on each other.
To calculate P(A|B), we can use the formula:
P(A|B) = P(A∩B) / P(B)
Since P(A∩B) = 0 and P(B) = 0.70, we have:
P(A|B) = 0 / 0.70 = 0
This means that if we know event B has occurred (i.e., P(B) > 0), then the probability of event A occurring (i.e., P(A|B)) is zero. Therefore, events A and B are not independent.
The student's argument that mutually exclusive events are independent is incorrect. Mutually exclusive events are by definition dependent events.
In general, the concept of mutually exclusive events and the concept of independent events are not the same. Mutually exclusive events are dependent events, while independent events are events that do not depend on each other.
In this problem, the fact that events A and B are mutually exclusive means that they are dependent events, and this is reflected in the probability calculation for P(A|B), which is zero. Therefore, we can conclude that mutually exclusive events are not independent events.

If each section of the trim takes 1/2 can of paint, how many sections of trim can he paint? Show your answer as an inequality with symbols, in words, and with a number line. Make sure your solution makes sense for this situation.
Answers
Answer: Robert has 35 cans of paint - 30 cans of paint that he has already used = 35 - 30 = 5 cans of paint left.
Since each section of trim takes 1/2 can of paint, Robert can paint 2 sections of trim with 1 can of paint.
Therefore, Robert can paint 5 cans of paint * 2 sections of trim per can = 10 sections of trim.
The inequality can be written as 10 <= sections of trim <= 10.
In words, the number of sections of trim that Robert can paint is less than or equal to 10.
On a number line, this solution can be represented as follows:
[9, 10, 11, ...]

One needs to connect the points where these arcs intersect the circle to form the desired shape. Finally, the angles need to be labeled to complete the unit circle.
A unit circle is a circle with a radius of 1. It is a tool used in trigonometry to measure angles and lengths of arcs. To calculate the length of an arc, one needs to know the angle it subtends at the center of the circle. The formula for finding this length is L = rθ, where L is the length of the arc, r is the radius, and θ is the angle subtended at the center. To fill in a unit circle, one needs to first calculate the lengths of the arcs subtended by the angles in the circle.

Answers
To solve the system of equations y=4x-3 and y=-2x+9, we can set the two equations equal to each other and solve for x:
4x - 3 = -2x + 9
Adding 2x and 3 to both sides, we get:
6x = 12
Dividing both sides by 6, we get:
x = 2
Now that we have the value of x, we can substitute it into either of the original equations to find the corresponding value of y. Let's use the first equation:
y = 4x - 3
y = 4(2) - 3
y = 8 - 3
y = 5
Therefore, the solution to the system of equations is x = 2 and y = 5. The solution is the ordered pair (2, 5).
If 0° ≤ Θ≤ 360°, then find angle(s) Θ.
1) sec Θ = undefined
Answers
Answer:
The secant function is undefined for angles where the cosine function equals zero, because dividing by zero is undefined. Therefore, we need to find the values of Θ where cos Θ = 0.
The cosine function equals zero at 90° and 270° (or π/2 and 3π/2 in radians), so we have:
cos 90° = 0, cos 270° = 0
Therefore, the angles that satisfy sec Θ = undefined are:
Θ = 90° + 360°k, Θ = 270° + 360°k
where k is an integer (positive, negative, or zero) that allows us to generate all possible angles in the range 0° ≤ Θ ≤ 360°.
So, the solutions for Θ are:
Θ = 90° + 360°k, Θ = 270° + 360°k
where k is an integer.
