Answer:
The degree of the given polynomial is 5
Step-by-step explanation:
The degree of a polynomial is the highest of the degrees of its monomials with non-zero coefficients.
The degree of a monomial is the sum of the exponents of the variables that appear in it.
We have the following polynomial:
[tex]3x^2y + 4xy + 1 - 5x^4y - 6y[/tex]
Degree of the first monomial: 2+1=3
Degree of the next monomial: 1+1=2
Degree of the next monomial: 0
Degree of the next monomial: 4+1=5
Degree of the next monomial: 1
Thus, the degree of the given polynomial is 5

Determine the y-intercept of the following parabola:
y = 3x2 - 12x - 5
Answer:
-5
Step-by-step explanation:
Find the y-intercept by plugging in x = 0:
y = 3x^2 - 12x - 5
y = 3(0^2) - 12(0) - 5
y = 0 - 0 - 5
y = -5
(0, -5)
[PLEASE ANSWER ASAP, ON TIME LIMIT!] The pH level of a substance can be determined by the formula pH = –log[H+], where [H+] is the hydrogen ion concentration in moles per liter. An alkaline substance has a pH level between 7 and 14. Which ion concentration corresponds to an alkaline substance?
Answer choices in picture.
Answer:
Option (2)
Step-by-step explanation:
pH level of a substance is determined by the formula,
pH = - log[H+}
where [H+] is the hydrogen ion concentration
Let the [H+] ion concentration = a
a = -log[H+]
log[H+] = -a
[H+] = 1 × [tex]10^{-a}[/tex]
Here 'a' is between 7 and 14.
Which means an alkaline substance must have the concentration between [tex]1\times 10^{-7}[/tex] to [tex]1\times 10^{-14}[/tex].
From the given options, [tex]5\times 10^{-12}[/tex] moles per liter lies in the given range.
Therefore, Option (2) will be the answer.

Answer:
A regular polygon has these characteristics:
3 or more sidesClosed shapeA polygon can not have one or two sides because that would be a line. It must have more than three sides, or else it is not a polygon.
A polygon is always a closed shape - it can not be an open shape or else it would not be a polygon, it would be considered an outline.

(Help me with this test question) Lines l and m are intersected by transversal t and l || m. Lines l and m are vertical with l to the left of m. Transversal t intersects them both slanting down and right. The angles formed above t with l and m from left to right are angles 1, 3, 5, and 7. The angles formed below t with l and m from left to right are angles 2, 4, 6, and 8. Select all the angles that are supplementary to ∠1. Group of answer choices ∠3 ∠4 ∠6 ∠5 ∠7 ∠8
Answer:
∠6 and ∠7
Step-by-step explanation:
To be complementary, they both in total have to sum 180°, and that mean that they have to form a com pleat and straight line. ;)
The supplementary angles of angle 1 are angles 2 and 3.
Two Angles are Supplementary when they add up to 180 degrees.From given figure,
It is observed that sum of angles 1 and 2 is equal to 180 degrees.The sum of angles 1 and 3 is equals to 180 degrees.[tex]\angle1 +\angle2=180\\\\\angle1 +\angle3=180\\[/tex]
Thus , the supplementary angles of angle 1 are angles 2 and 3.

Answer:
13 seconds
Step-by-step explanation:
Since distance is directly proportional to time,
distance = time * a constant
Lets make A the constant
So, 54 = 9A
A = 6
Now, since distance = 78,
78 = time * A
From above, we can see that A = 6, so
78 = time *6
time = 13
Answer:
13
Step-by-step explanation:
54/9=6, 6 is the rate at which the car travels. 78/6 is 13 so that is how far the car traveled

Step-by-step explanation:
-11 + x = -2, -11 + 9 = -2 -2 + x = 7, -2 + 9 = 7, 7 + 9 = 16 -2 - x = -11, -2 - 9 = -11 7 - x = - 2, 2 + x = 11, 11 - 2 = 9, 9 = x 7 - 7 = 0 - 2 = -2, 7 + 2 = 9, 7 - 9 = -2
16 + 9 = 25, 25 + 9 = 34, 34 + 9 = 43

In last weekend's track meet, Lakeland High School had 30 individual-
event placers score a total of 111 points. First-place finishers score 7 points, second-place finishers score 4 points, and third-place finishers score
1 point. The number of first- and second-place finishers was twice the
number of third-place finishers. Find the number of runners that finished in
each place.
Answer:
The number of runners that finished in first place , second place and third place are 7 , 13 and 10 respectively.
Step-by-step explanation:
Let the no. of runners fished at first place be x
Let the no. of runners fished at second place be y
Let the no. of runners fished at third place be z
We are given that Lakeland High School had 30 individual- event placers
So, x+y+z=30 -----1
First-place finishers score 7 points
So, Total score of x runners = 7x
Second-place finishers score 4 points
So, total score of y runners = 4y
Third-place finishers score 1 point.
So, total score of z runners = z
We are given that 30 individual- event placers score a total of 111 points
So, 7x+4y+z=111 ----2
We are also given that The number of first- and second-place finishers was twice the number of third-place finishers.
x+y=2z ---3
Substitute the value from 3 in 1
x+y+z=30
2z+z=30
z=10
Substitute the value of z in 1 and 2
x+y=20 ----4 and 7x+4y=101 ---5
Substitute the value of x from 4 in 5
7(20-y)+4y=101
140-7y+4y=101
140-3y=101
39=3y
`13=y
Substitute the value of y and z in 1
x+13+10=30
x=7
Hence the number of runners that finished in first place , second place and third place are 7 , 13 and 10 respectively.

Given these processes: 1. cartilage ossification 2. bony callus formation 3. hematoma formation 4. fibrocartilaginous callus formation 5. remodeIing of woven (spongy) bone into compact bone Which sequence best represents the order in which the processes occur during repair of a fracture?
Answer:
The sequence that best represents the order during repaid of a fracture as as
follows
3. hematoma formation
4. fibrocartilaginous callus formation
2. bony callus formation
1. cartilage ossification
5. remodeling of woven (spongy) bone into compact bone
Step-by-step explanation:
When a bone is fractured, the first step following a bone fracture is hematoma formation.
Hematoma formation is formed when a little blood escapes from the blood vessels and remains in the skin's thickness, creating a blue spot. The hematoma is an effusion of blood that occurs deeper under the skin.
From there, the formation of tissues begins from end to end of the broken bones. It is a reorganization of the bone tissue (the bone itself), allowing the consolidation of a fractured bone. This bone formation welds the two parts of the broken bone together for a particular period depending on the patient's bone tissue condition. This bone callus will form in two episodes.
1) There first appears a fibrocartilaginous callus, also called connective callus, which allows the fracture to heal in a few weeks. It is an immature bone.
2) In a second step, this immature bone is gradually replaced by another bone (calcified/bony) resembling the bone which has been fractured.
From there, the ossification of the callus occurs where the bony callus is further replaced by woven spongy bones to form a stronger stabilizing collar.
Finally, the remodeling of woven (spongy) bone into compact bone takes place. Lamellar bones are replacing these woven spongy bones.
