find an expression in terms of n for the nth term of this sequence, 15,19,25,33,43
Answer:
Hello,
Step-by-step explanation:
P(n)=ax²+bx+c (quadratic sequence)
with a=1,b=1,c=13
[tex]\\\boxed{u_n=n^2+n+13}\\[/tex]
Answer:
tₙ = n² + n + 13=============================
Given sequence:
15, 19, 25, 33, 43, ...We can see this not AP or GP as the difference or ratio of consecutive terms is not common.
But we can see the difference between terms has common difference of 2:
19 - 15 = 425 - 19 = 633 - 25 = 843 - 33 = 10and
10 - 8 = 28 - 6 = 26 - 4 = 2It means the sequence is of the second degree, in other words it is quadratic.
In general it is of the form:
tₙ = an² + bn + c, where a, b, c are coefficients, n - is the number of the terms.Use the terms of the given sequence to work out unknown coefficients.
t₀ = 15 - (4 - 2) = 15 - 2 = 13
a(0)² + b(0) + c = 13c = 13It gave us the value of c.
t₁ = 15
a(1)² + b(1) + c = 15a + b + c = 15a + b + 13 = 15a + b = 2t₂ = 19
a(2)² + b(2) + c = 194a + 2b + c = 194a + 2b + 13 = 194a + 2b = 6Compare the last two equations and solve for a and b:
a = 2 - b4(2 - b) + 2b = 68 - 4b + 2b = 62b = 8 - 62b = 2b = 1Then
a = 2 - 1 a = 1So we know the coefficients:
a = 1, b = 1, c = 13The nth term equation is:
tₙ = n² + n + 139-3-3-3 = 0 written as a division problem
The value of 9-3-3-3=0 written as division problem is the value of 0.333
According to the Honor algebra:
The symbols for variables used in algebra, which may be found in Greek and Latin literature, can be used to date the creation of algebra to the height of Greek or Latin culture.
9-3-3-3=0 as written as division
⇒ 9÷3÷3÷3 =0
⇒ 9÷3 =3÷3
⇒ 3=1
⇒ x=1/3
⇒ x=0.333
so, the value of 9 divide by 3 and divided by 3 equals to 3 divvied by 3 is the value of 0.333.
When things are more realistic, algebra becomes much more intriguing. With a two-pan balance, some mystery bags, and a ton of jelly beans, solving linear equations is much more enjoyable.
Therefore, the 9-3-3-3=0 written as division is the value of 0.333.

Answer:

Step-by-step explanation:
Dontavious has a box of colored pencils. He uses 53 pencils and has 118 pencils left in the box. Write an equation showing how many pencils are in the box before he starts drawing.
53 + p = 118
118 + p = 53
p − 53 = 118
p = 118 − 53
An equation showing the number of pencils that are in the box before he starts drawing is p - 53 = 118.
We are given that:
Dontavious has a box of colored pencils.
Dontavious uses 53 pencils.
Pencils still left in the box = 118.
Let the total number of pencils in the box be p.
So, the equation representing the situation given will be:
p - 53 = 118
As from p pencils, 53 pencils have been used and 118 pencils still remain at the end.
Therefore, we get that, an equation showing the number of pencils that are in the box before he starts drawing is p - 53 = 118.

Step-by-step explanation:
2) Use three functions above to evaluate the following: input f(x)=x-3_soupat f(3) = -3 p(0) = p(x)=0, x= function p(-4)= x/g(x) p(x)=5, x= 5 2 -3 f(x)=12, x=-4 f-3 = 12 -3 36207 g(-3)= p(1)= | p(3)= g(x)= -3, x = 95 = -3 p(x)=1, x= p(x)=2, x=
Answer:
f(3) = 3 - 3 --> f(3) = 0
f(x) = 12, x = 15 (because 15 - 3 would equal 12)
g(-3) = 2 (because in the chart for g(x), an x of -3 is 2)
g(x) = -3, x = 5 (because in the chart for g(x), a g(x) of -3 is an x of 5)
For the graph questions, p(0)= means that the 0 is the x integer and you must find the y when x=0
p(0) = 3
p(-4) = 5
p(1) = 3
p(x) = 1, x = 2
For the graph questions, p(x)=0 means that the 0 is the y integer and you must find the x when y=0
p(x) = 0, x = 2.5
p(x) = 5, x = -4
p(3) = -1
p(x) = 2, x = 1.5

Enter your answer in the box.
__Units Sqared
The area of the composite figure whose vertices have the (2,-2), (2,1), (4,2), (6,2), (4,-1) coordinates is 6 square units
We first need to plot all the given points A (2,-2), B (2,1), C (4,2), D (6,2)and E (4,-1) which is coordinate geometry
After joining the Points which is a pentagon and it can be divided in two shapes one is triangle CDE and a quadrilateral ABCE
Using the distance formula
BC = [tex]\sqrt{(y2-y1)^{2}+(x2-x1)^{2} }[/tex] = [tex]\sqrt{(2-1)^{2} + (4-2^{2} }[/tex] = √5
Since BC = AE and BC ll AE , we can say ABCE is a parallelogram
area of a parallelogram = base × Altitude
= 2 × 2= 4
Area of triangle CDE where CD is perpendicular and CE is the base
= 1/2 ( 2×2)
= 1/2 (4)
= 2 square units
So the area of ABCDE = Area of ABCE + area of CDE
= 4 square units + 2 square units
= 6 square units
Hence, the area of the composite figure whose vertices have the (2,-2), (2,1), (4,2), (6,2), (4,-1)coordinates is 6 square units

Employees in 2012 paid 4.2% of their gross wages towards social security (FICA tax), while employers paid another 6.2%. How much will someone earning $39,000 a year pay towards social security out of their gross wages?
Someone who is earning $39,000 a year, would pay $1,638 towards social security out of their gross wages
Employees in 2012 paid 4.2% of their gross wages towards social security tax.
As the gross yearly wages of an employee is $39,000 and he have to pay the 4.2% of his gross wages towards social security or FICA tax.
Percentage means division by 100 and to know the contribution of the employee we need to multiply the percentage with the gross wages of the employee
He paid towards social security = 4.2% of 39000
= 4.2/100×39000
= 0.042 × 39000
= $1,638.00

Find the value of k the diagram is not to scale
○ 42
○ 70
○ 118
○ 58
Answer:
70
Step-by-step explanation:
We can actually solve this based on two “rules” that are present in triangles and lines.
The first rule is that the three angles inside a triangle will always add up to 180.
In this case, we have 2 out of 3 angles given like so: 52 + 58 + k = 180
Solve for k and that gives 70
Another rule that reinforces this is that a straight line will have an angle of 180 degrees. With the 180 that is given, we can solve for k again using: 110 + k = 180
Answer:
70°
Step-by-step explanation:
Total angles of a triangle = 180°
Then, 180° = 58° + 52° = k
➟ 180° = 58° + 52° = k
➟ 180° - 180° + k =180° - (58° + 52°)
➟ k = 180° - 110°
➟ k = 70°
*100 POINTS ANSWER ASAP*
Complementary Angles- When the sum of two angles is equal to 90 degrees, they are called complementary angles. (For example, 30 degrees and 60 degrees are complementary angles)
Supplementary Angles-Supplementary angles are those angles that sum up to 180 degrees. (For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°.)
Congruence Postulate- to be congruent if two angles and the side between these two angles of one triangle are congruent to corresponding angles and the included side (side between two angles) of the other triangle
Linear Pairs of Angles-A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
The sum of the angles of a regular hexagon is 720 degrees. Solve for x
Answer:
x = 32
Step-by-step explanation:
Measure of each interior angle of a regular hexagon is 120°-> (4x - 8)° = 120°-> 4x - 8 = 120-> 4x = 120 + 8-> 4x = 128-> x = 128/4-> x = 32Jeffrey simplified the algebraic expression and made an error. Find and fix the mistake.

The garden store was able to sell a total of 1,960 bags of potting soil on Saturday and Sunday.
What is distributive property of multiplication over addition ?
If we multiply a number by the sum of more than two, we use the distributive property of multiplication over addition.
In order to find the number of bags of potting soil sold over those two days, the first step is find out the number of pallets store sold there potting soil :
= 17( on Saturday) + 23 (Sunday)
= 40 palettes
Each palettes has 7 flats so the total number of flats sold is:
= 40 x 7
= 280 flats
Each flat then contains 7 bags so the total number of bags sold is:
= Number of flats sold x 7
= 280 x 7
= 1960 bags
In conclusion 1,960 bags of potting soil were sold.
