The piecewise defined function f(x) is graphed below. What is the value of f(5)?
================================================
Explanation:
Draw a vertical line through 5 on the x axis. This represents the equation x = 5. Notice that we intersect the blue line at (5,-1) which tells us that f(5) = -1. There's a closed point here, meaning that the point is included. This is in contrast to the open hole at (5,3) which is not part of the function. So be careful not to say that f(5) = 3 because that's not the case.
Answer:
i think it's f(5) - a wild guess

Which undefined term is used to define an angle?
line
plane
point
ray
The undefined term is point.
What is an angle?In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle. Let us read about the different parts of an angle.
Parts of an Angle
There are two main parts related to an angle - the arms and the vertex.
Arms of the Angle
The two rays which join at a common point to form the angle are called the arms of the angle. Observe the figure given below which shows that OA and OB are the arms of the angle AOB.
[tex]vertex[/tex]of the angle
[tex]vertex[/tex] is a common endpoint that is shared by the two rays. Observe the figure in which the [tex]vertex[/tex] O is marked as the joining point of the two arms.
Measure of an angle
An angle is measured in degrees. One full rotation around a point forms a complete angle of 360°.
As, the is defined on the basis of arms , vertices, measurement.
They all related to point and point doesn't have a particular definition.

Answer:
sin D = 0.25
Step-by-step explanation:
If ∠E = 90°, it means that the triangle is a right angle triangle.
Thus, hypotenuse will be the longest side which will be DC = 65
Since we are given CE = 16 and ED = 63, I have attached a diagram showing this triangle.
From the diagram, since we are looking for sin ∠D, we can say that;
sin D = opposite/hypotenuse
Now, opposite = CE = 16
Hypotenuse = CD = 65
Thus;
sin D = 16/65
sin D = 0.2462
Approximating to the nearest hundredth gives;
sin D = 0.25

Measurement question please show work thank you
Answers:
b) 92100 decimeters
c) 6650 decaliters
=====================================================
Work Shown for part b)
1 decameter = 10 meters
1 decimeter = 1/10 of a meter
10 decimeters = 1 meter .... multiply both sides by 10
100 decimeters = 10 meters ... multiply both sides by 10
100 decimeter = 1 decameter
921*(100 decimeter) = 921*(1 decameter)
92100 decimeters = 921 decameters
-------------------
Work Shown for part c)
We could follow the same idea as part b). I'm going to use another approach as shown in the diagram below. This conversion method is known as the railroad tracks method in some math textbooks.
Each column represents two things that are equivalent to one another. For example, 1 kiloliter is the same as 1000 liters. So each column, when you divide top over bottom, represents the value 1.
Notice the unit cancelations as shown by the color coding. The goal is to have every unit cancel except for the decaliters unit which is what we want to end up with ultimately.
Once you have the railroad tracks set up, you multiply straight across.
Along the top, we have 66.5*1000*1 = 66500
Along the bottom we have 1*10 = 10
Divide those results: 66500/10 = 6650
So 66.5 kiloliters converts to 6650 decaliters
Answer:
1) 92100 dm
2) 6650 decalitres

O a is to the left of b.
a and b are the same distance away from 0.
a is to the right of b.
There is not enough information given.
Answer:
a is to the right of b. On a number line the orientation has 0 as the starting number and counts on each whole number integer on to the eight. Therefore if a is greater than b, be will be toward the left and a will be toward the right.

Answer:
20
Step-by-step explanation:
We know that the diagonals are bisected, which means
2x+4 = 6x-8
Subtract 2x from each side
2x+4-2x = 6x-8-2x
4 = 4x -8
Add 8 to each side
4+8 = 4x-8+8
12 = 4x
Divide by 4
12/4 = 4x/4
3 =x
We want to know CF = DB = 2x+4 + 6x -8
CF = 8x-4
= 8(3) -4
= 24-4
= 20
