what is the leading coefficient of this polynomial? y=5x² + 3x^6 -10x-8,
Explanation:
The equation y = 5x^2+3x^6-10x-8 is not in standard form.
Why not? Because the term with the largest exponent (6) isn't listed first.
The standard form would be y = 3x^6+5x^2-10x-8; note the exponents decrease (6, 2, 1, then 0).
After the polynomial is in standard form, we can read off the leading coefficient to be 3. This is the coefficient of the first term 3x^6.

Step-by-step explanation:
solve the inequality and explain how
Answer:
B. (see attached)
Step-by-step explanation:
You want the solution and graph of the inequality |x+3| > 2.
SolutionThe inequality resolves to two inequalities with different domain definitions:
|x +3| > 2
When the argument is negative, (x+3) < 0, this is ...
-(x +3) > 2
-x -3 > 2 . . . . . . eliminate parentheses
x +3 < -2 . . . . . . multiply by -1
x < -5 . . . . . . . . . subtract 3; consistent with the domain definition
When the argument is positive, (x+3) > 0, this is ...
x +3 > 2
x > -1 . . . . . . . . subtract 3
-1 < x . . . . . . . . same thing using the < symbol
These differing solution sets do not overlap, but elements of either set are solutions to the inequality. The appropriate conjunction is "OR":
solution: x < -5 or -1 < x
The graph is attached.
__
Additional comment
We like to use the < or ≤ symbols when expressing the solution to an inequality. That way, the relation of the variable to the boundary value is the same as its relation on a number line. Solution values are left of -5 or right of -1:
x < -5 or -1 < x
It helps provide a check that the graph is properly drawn.
The inequality can be rewritten as ...
|x -(-3)| > 2
which can be interpreted as saying the positive distance from x to -3 is more than 2. This tells you the graph will have two disjoint branches, and the appropriate conjunction is OR.
If the problem were different, and the inequality were ...
|x -(-3)| < 2
it would be telling you the solution values have a distance less than 2 from -3. They will be in one continuous band from -5 to -1, so the appropriate conjunction is AND. The solution in this case is usually written as a compound inequality with no conjunction: -5 < x < -1. (Note the use of < symbols puts the variable value in the middle, between the boundary values, as in graph D.)

Miguel has three times as many dimes as he has quarters. He has as many nickels as he has dimes and quarters combined. The total amount of money he has is $3.00. How many of each coin does Miguel have?
After solving the algebraic equation, Miguel has 4 quarters, 12 dimes and 16 nickels.
What is algebra?
One of the earliest areas of mathematics that deals with number theory, geometry, and analysis is algebra. Algebra is also defined as the study of mathematical rules and symbols through the manipulation of those mathematical symbols.
The number of quarters is taken to be x, then the number of dimes will be 3x, and the number of nickels will be 3x + x = 4x
$3.00 when converted to cents is 300 cents.
The value of nickels is 5 x 4x=20x.
The value of dimes is 10 x 3x=30x.
The value of quarters is 25x.
As the total value of money Miguel has is 300 cents, then the algebraic equation will be -
20x + 30x + 25x = 300
Solve to get the value of x -
75x = 300
x = 4
Therefore, the amount of quarters is x = 4 quarters.
The amount of dimes is x = 3x = 3 x 4 = 12 dimes.
The amount of nickels is 4x = 4 x 4 = 16 nickels.

Two sectors of a circle of radius $12$ overlap as shown, with $P$ and $R$ as the centers of the respective circles. Determine the area of the shaded region.
The area of the shaded region is 26.088 sq units.
A circle is a particular type of ellipse in mathematics or geometry where the eccentricity is zero and the two foci are congruent. A circle is also known as the location of points that are evenly spaced out from the center.
The radius of a circle is measured from the center to the edge. The line that splits a circle into two identical halves is its diameter, which is also twice as wide as its radius.
Area of a 60-degree sector of a circle with radius 12 = 60/360 pi 12^2 Since, there are two of these minus the area of equilateral triangle = sqrt3 /4 12^2 = 60/360 pi 12^2 * 2 - sqrt3 /4 12^2 *2 = 26.088 sq units

Suppose that $2000 is loaned at a rate of 7%, compounded semiannually. Assuming that no payments are made, find the amount owed after 4 years.
Answer:
$2581.60
Step-by-step explanation:
In order to find the amount owed after 4 years, we need to use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A is the amount owed after t years
P is the principal, or initial amount borrowed
r is the interest rate
n is the number of times the interest is compounded per year
t is the number of years
Plugging in the given values, we have:
A = $2000(1 + 0.07/2)^(2*4)
= $2000(1.035)^8
= $2000(1.2908)
= $2581.60
Therefore, the amount owed after 4 years would be $2581.60.

Two lines are parallel if they have the same arrow head marking.
If two parallel lines are cut by a transversal, the following angles are created:
alternate interior anglesalternate exterior anglesvertical anglesadjacent anglescorresponding anglesI have attached an image of the different types of angles to this response.
Thus, we can use the types of angles to solve for ∠8.
∠3 and ∠5 are corresponding angles. Therefore, they have the same measure.
Set up the equation to solve for x:
∠3 = ∠5
9x + 14 = 14x - 1 . . . . . . substitute the values
14 = 5x - 1 . . . . . . . . subtract 9x from the LHS and RHS
15 = 5x . . . . . . . . . . add 1 to the LHS and RHS
∴ 3 = x . . . . . . . . . . . . divide the LHS and RHS by 5 to isolate x
Now that we know what x is, we can substitute it into the value of ∠3.
∠3 = 9x + 14
∠3 = 9(3) + 14 . . . . substitute the values
∠3 = 27 + 14 . . . . . compute
∴ ∠3 = 41
∠3 and ∠8 are adjacent angles. Therefore, they add up to 180°.
Set up the equation to solve for ∠8:
∠8 + ∠3 = 180
∠8 + 41 = 180 . . . . substitute the known values

Find the measure of an interior angle of a regular hexagon
Therefore , the solution of the given problem of angles comes out to be
Each inner angle of a regular hexagon measures 120 degrees.
Exactly what angles are there?Two rays that converging at the vertex, or center, of an angular structure in geometry make up the structure. We refer to these rays as the faces of the angle. Two beams may well be able to create any angle within just a planar depending on their location. Additionally, an angle is created when two planes intersect. .
Given: A standard hexagon
Measure each internal angle of a standard hexagon.
Solution:
(n - 2) x 180° is the formula for the sum of lengths of a polygon's inner angles.
Every side of a regular polygon is the same length, and every angle is the same size.
A hexagon has six sides.
Find the total of the measurements of the internal angles of a hexagon by substituting n = 6 in (n - 2) x 180n latitude in step 1.
=> (n - 2) * 180°
=> (6 - 2) * 180°
=>4 * 180°
=> 720°
Step 2: Since a regular hexagon has six sides and all of its sides and angles are equal in size, divide by six to obtain the dimensions of each inner angle.
=> 720° /6
=> 120°
Each internal angle of such a regular polygon is 120 degrees in length.
