Given:
The graph of a piecewise function.
To find:
The points of discontinuity.
Solution:
The function is discontinuous at a point if:
1. There is a jump in the graph of function.
2. There is a hole in the graph at that point.
3. The function approaches to infinite at that point.
From the given graph it is clear that the graph of the function has jumps are at points [tex]x=-2[/tex] and [tex]x=0[/tex].
So, the function is discontinuous at [tex]-2,0[/tex].
Therefore, the correct option is (c).
Help me it says use the figure for 1 and 2
True or false? The graph represents a function. 5. -5 5 2.5 O A. True O B. False
Answer:
True
Step-by-step explanation:
In functions, each x value has its own corresponding y value, this meaning that the x value cannot repeat, and if it does it is not considered a function
Looking at the graph, no x value repeat, thus the graph represents a function

4. A car is travelling 75 kilometers per hour. How many meters does the car travel in one
minute?
Answer:
1250 Meters
Step-by-step explanation:
75 kilometers divided by 60 minutes is 1.25 kilometers per minute.
1 kilometer = 1000 meters
Answer:
75km/hr =75000
60 sec =1min,60 min=1hr
75000÷60=1250m
What is the missing length?
Answer:
16
Step-by-step explanation:
The area of a triangle is
A =1/2 bh where b is the base length and h is the height
Substitute the values in
69.6 = 1/2 ( 8.7) * p
69.6 = 4.35p
Divide each side by 4.35
69.6/4.35 = p
16 = p
The formula for the area of a triangle is: A = 1/2 * base * height.
Using this formula, let's plug in what we know.
69.6 = 1/2 * 8.7 * height
Next, we'll go ahead and get rid of that 1/2 by multiplying everything by its reciprocal, 2.
139.2 = 8.7 * height
Then, all that's left is to divide both sides by 8.7.
Height = 16 yards
Hope this helps!! :)
Can someone please explain the Pythagorean theorem to me?
Answer:
Pythagoras theorem is is a mathematical law that states that the sum of squares of the lengths of the two short sides of the right triangle is equal to the square of the length of the hypotenuse.
Step-by-step explanation:
The hypotenuse is the side opposite to the right angle and so the equation for finding the hypotenuse would be:
a^2+^b^2=c^2

Answer:
Step-by-step explanation:
Un-shaded area = 3.14 x 2 squared = 12.56
Shaded area = (3.14 x 4 squared) - Area of un-shaded area
= 50.24 - 12.56 = 37.68
Answer:
37.68 sq cm
Step-by-step explanation:
Area = pi x r²
Area shaded = area whole circle minus area white circle
pi x 4² -pi x 2²
pi x 16 - pi x4
pi(16-4)
pi(12)
3.14 x 12 = 37.68

Solve for x and y. X= Y=
Answer:
x = 82°
y = 8°
Step-by-step explanation:
x + 98° = 180°
x = 180° - 98°
x = 82°
x + y = 90°
82° + y = 90°
y = 90° - 82°
y = 8°

Ms. Madero sells tables. She charges $26 per square foot of the tabletop and charges a fixed fee of $75. Which equation could be used to find the area
(x), in square feet, of the tabletop of a table that Ms. Madero sells for $244?
O 26x + 75 = 244
O 26x = 75 +244
O 75x + 26 = 244
O 75x = 26 +244
Answer:
26x+75=244

The sum of the ages of Noah and Billy is 25; the sum of the ages of Noah and Ty is 20; and the sum of the ages of Billy and Ty is 31. Who is the oldest of the three and how old is he?
Answer:
the oldest is Ty and his age is 24
Step-by-step explanation:
Let us assume the billy age be x
Noah age be y
And, Ty age be z
Now according to the question
y + x = 25 ..........(1)
y + z = 20..........(2)
x + z = 31..............(3)
z = 31 - x
since
y + z = 20
y + 31 - x = 20
y - x = -11 .............(4)
Now solve (1) and (4) equation
So,
y + x = 25
y - x = -11
2y = 36
y = 18
x = 25 - 18
= 7
z = 31-7
= 24
Hence, the oldest is Ty and his age is 24
How can you tell from the equation of a rational function if the function has a hole in the graph ( a removable discontinuity) at x, rather than a vertical asymptote? Give an example
Consider that,
x^2+4x+4 = (x+2)(x+2)
x^2+7x+10 = (x+2)(x+5)
Dividing those expressions leads to
(x^2+4x+4)/(x^2+7x+10) = (x+2)/(x+5)
The intermediate step that happened is that we have (x+2)(x+2) all over (x+2)(x+5), then we have a pair of (x+2) terms cancel as the diagram indicates (see below). This is where the removable discontinuity happens. Specifically when x = -2. Plugging x = -2 into (x+2)/(x+5) produces an output, but it doesn't do the same for the original ratio of quadratics. So we must remove x = -2 from the domain.
Planet Fitness charges a one-time membership fee of $25 and then a monthly charge of $10. Retro Fitness charges a one-time membership fee of $10 and then a monthly charge of $20. When is it less expensive to join Planet Fitness
Answer:
x < 3/2 month
Step-by-step explanation:
Let
x = number of months
Planet fitness:
25 + 10x
Retro fitness:
10 + 20x
Equate
25 + 10x < 10 + 20x
25 - 10 < 20x - 10x
15 < 10x
x < 15/10
x < 3/2 month
It is less expensive to join planet when the number of months is less than 3/2 months

ABCD is a rectangle find each value
Answer:
Step-by-step explanation:
for angle <ADB= 90-31= 59 degrees
for angle <ACD= ACD have the same shape like BDC so it will be 31 degrees
for angle< DBC= remember ADB and ABD are same so the angle ADB is equal to ABD. So it is 59 degrees.
for angle<DEC= Add both angles C and D 31 and 31.
so
<DEC+31+31=180
<DEC+62=180
<DEC=180-62
<DEC= 118DEGREES

The model represents an inequality. What is the solution set for the inequality?
Given:
The figure of an algebraic tiles model of an inequality.
To find:
The inequality for the given model.
Solution:
On the left hand side of the inequality sign in the model we have 8 tiles of x and 12 tiles of 1. So,
[tex]LHS=8(x)+12(1)[/tex]
[tex]LHS=8x+12[/tex]
On the right hand side of the inequality sign in the model we have 12 tiles of -1. So,
[tex]RHS=12(-1)[/tex]
[tex]RHS=-12[/tex]
Now, the inequality for the given model is:
[tex]8x+12\geq -12[/tex]
Therefore, the required inequality for the given model is [tex]8x+12\geq -12[/tex].
