Given the piecewise function above evaluate the following statements. (write "DNE" if the limit does not exist)
By analyzing the graph of the function, we will see that:
a) DNEb) 3c) -1d) 3e) DNEf) 2How to get the limits of the given function?
Remember that when we take a limit to a given value, we approach to that value by two directions (from above and below) and see at which value the function approaches.
So, for the first limit we have:
x ⇒ -2
As you can see, if we approach from below the function tends to 4, while if we approach from above, the function tends to -1, which means that this limit does not exist. DNE.
x ⇒ 0
The function is continuous here, so the limit is equal to the value of the function in that point, which is 3
x ⇒ 2
If we approach from above and below we get the same number, which is -1, so the limit is equal to -1.
x = 2
Now we are directly evaluating the function in x = 2, and we can see that there is a jump such that f(2) = 3
x ⇒ 4
Here we have two asymptotes, one goes to infinity and the other to negative infinity, so this limit does not exist.
x ⇒ ∞
So we can't see how the function behaves for large values of x, so there is no way to answer this exactly.
If we suppose that the function does not change, we can see that we have a rational function in the right side of the image, so we can expect that as x tends to infinity, the function will tend asymptotically to 2.
Why 2?
Because the denominator becomes zero when x = 4, then when x = 5 the denominator is equal to 1.
At that point, the function is equal to 3, so the function is something like:
y = 1/(x - 4) + 2

A right cylinder has a radius of 7 cm and a height of 3 cm.
Answer the following questions and make sure to *show all your work.*
(a) Find the *Surface Area* of the cylinder
(b) Find the *Volume* of the cylinder
(c) If you wanted more volume in your cylinder, which of these two ideas would give the most *Volume?*
1. Doubling the radius to 14 cm, while the height remains 3 cm.
OR
2. Tripling the height to 9 cm, while the radius remains 7 cm.
Answer:
V = 141.37 cm³
Surface area = 150.80 cm²
Step-by-step explanation:
Answer:
V = 141.37 cm³
Surface area = 150.80 cm²
i. Doubling the radius to 6 cm, while the height remains 5
Step-by-step explanation:
Given that :
Radius, r = 3cm
Height, h = 5cm
Volume, V of right cylinder :
V = πr²h
V = π * 3² * 5
V = 141.37166
V = 141.37 cm³
Surface Area :
2πr(h + r)
2 * π * 3(3 +5)
18.849555(8)
150.79644
= 150.80 cm²
Volume at r = 6 ; h = 5
V = π * 6² * 5
V = 565.48667 cm³
Volume at r = 3 ; h = 15
V = π * 3² * 15
V = 424.11500 cm³
Answer:
See below
Step-by-step explanation:
Part A
The surface area of a cylinder is [tex]SA=2\pi rh+2\pi r^2[/tex] with [tex]r[/tex] being the radius and [tex]h[/tex] being the height:
[tex]SA=2\pi rh+2\pi r^2\\\\SA=2\pi(7)(3)+2\pi(7)^2\\\\SA=2\pi(21)+2\pi(49)\\\\SA=42\pi+98\pi\\\\SA=140\pi[/tex]
Therefore, the surface area of the given cylinder is 140π cm².
Part B
The volume of a cylinder is [tex]V=\pi r^2h[/tex]:
[tex]V=\pi r^2h\\\\V=\pi (7)^2(3)\\\\V=\pi(49)(3)\\\\V=147\pi[/tex]
Therefore, the volume of the given cylinder is 147π cm³.
Part C
The first cylinder would have a volume of [tex]V_1=\pi(14)^2(3)=\pi(196)(3)=588\pi cm^3[/tex]
The second cylinder would have a volume of [tex]V_2=\pi (7)^2(9)=\pi(49)(9)=441\pi cm^3[/tex]
Therefore, the first cylinder with a radius of 14cm and a height of 3cm gives a greater volume of 588π cm³.

Line BC is represented by 3x + 2y = 8. Line AD is
represented by -3x - 2y = 6. What is the relationship of
line BC to line AD? Explain
how the sum of
the equations
demonstrates this relationship.
Answer:
In explanation
Step-by-step explanation:
So, let's solve for y in both of these equations
3y + 2x = 8
3y = 2x+8
y = 2/3x+8/3
-3x - 2y = 6
-2y = 3x + 6
y = -3/2x-3
The lines are perpendicular, since their slopes are the negative reciprocal of each other.
Negative reciprocal => -1/n
The sum of the equations demonstrates this relationship, with 0x + 0y = 14
or 0 = 14 in which a result like this only occurs when the lines are perpendicular
Your welcome, comment if you have any questions! :D
Answer:
Line BC is parallel to line AD. The system of equations has the sum 0 = 14. Since this is a false equation, the system has no solution, which means the lines will never intersect.

Step-by-step explanation:
Bug P starts at 0 and moves along a number line in the positive
direction. Bug N starts at 0 and moves in the negative direction. Each
bug moves at a constant speed, but one bug travels faster than the other.
Bugs P and N leave 0 at the same time, and four seconds later P is at 12
and N is at –8
a) Suppose Bug P reaches point x in t seconds, and Bug N reaches
point y in t seconds. Express x in terms of t. Then express y in terms
of t.
b) How far apart are bugs P and N thirty seconds after leaving point 0?
c) When will bugs P and N be 300 units apart?
d) Draw a graph that shows how the distance between the bugs depends on
the amount of time that has passed.
e) Is the distance between the bugs directly proportional to time, inversely
proportional to time, or neither?
By getting the motion equations for the bugs, we will see that:
a)
x = (3 units per seg)*ty = (-2 units per seg)*tb) 150 units.
c) 60 seconds
d) The graph can be seen at the end.
e) Directly proportional.
Getting the motion equations:
a) We know that bug P moves 12 units in 4 seconds, then its velocity is:
Vp = 12/4s = 3 units per seg.
And bug N moves -8 units in 8 seconds, then its velocity is:
Vn = -8/4s = -2 units per seg.
Then we have:
x = (3 units per seg)*ty = (-2 units per seg)*tb) The distance between the bugs at the time t is:
d = x - y
At 30 segs, that distance is:
d(30s) = (3 units per seg)*30s - (-2 units per seg)*30s = 150 units.
c) Now we need to write:
d = 300 units = (3 units per seg)*t - (-2 units per seg)*t
300 units = (5 units per seg)*t
(300 units)/(5 units per seg) = t = 60s
The distance between the bugs will be 300 units after 60 seconds.
d) The graph of:
d(t) = (5 units per seg)*t
Can be seen at the end.
e) As the time increases also does the distance, so these two are proportional.

Now, we can use the law of sines to get that:
[tex]\frac{\sqrt{10^{2}+14^{2}-2\cdot 10 \cdot 14 \cdot \cos 70^{\circ}}}{\sin 70^{\circ}}=\frac{14}{\sin \angle ABC}[/tex]
Meaning that [tex]\sin \angle ABC =\frac{14\sin 70^{\circ}}{\sqrt{10^{2}+14^{2}-2 \cdot 10 \cdot 14 \cdot \cos 70^{\circ}}}[/tex]

Identify the smallest composite number that you can create by multiplying two different composite numbers
Answer:
Step-by-step explanation: A composite number is defined to be a number which has other divisors besides 1 and the number itself. Start counting:1, 2, 3, 4, 5, 6……….
1 is not a composite number because its sole divisor is 1. 2 is not a composite number because it has only two divisors 1 and the number 2 itself. 3 is in the same class as 2.
But 4 is different. Its divisors are 1,2,4. So this number satisfies the criterion of a composite number as stated above since besides 1 and 4, 2 is also a divisor. 4 is also the smallest composite number. The next composite number after 4 is 6 which has as divisors 1,2,3,6.
