The sum of given polynomials (m + n + 3) + (m + n + 4) is 2m + 2n + 7
A polynomial is an equation composed of more than two algebraic terms, particularly the sum of numerous terms containing different powers of the same variable(s)
The polynomials can be added by first organising them in standard form, then grouping like terms together, and lastly simplifying them.
Given the expression:

Write your answer as a polynomial or a rational function in simplest form.
A polynomial or a rational function in simplest form is (f. g)(x) is 4x² + 25x + 6.
What is Polynomial?The exponents of all the variables of an algebraic statement known as a polynomial must all be whole numbers. In any polynomial, the exponents of the variables must be non-negative integers.By identifying which phrases only contain the processes of adding, subtract, multiplying, and non-negative integer exponents, the polynomials can be located. Expressions with additional processing are considered as non expressions.
Given, f(x) = 4x + 1
g(x) = x + 6
Now, (f. g)(x) = f(x).g(x)
= (4x + 1)(x + 6)
= 4x² + 24x + x + 6

At Chocolatier Incorporated, there are two factors that determine the cost of health

$52 per month for
individual coverage and $98 per month for family coverage. If an employee makes at
least $65,000 per year, individual coverage is $67 per month and family coverage is
$122 per month.
a) Graham makes $62,800 per year. He has individual health care. His yearly contribution
is 10% of the total cost. How much does his employer contribute?
b) Claudia s annual salary is $75,400. She has family health care. Her employer
contributes $1,052 per month toward her total coverage cost. What percent does
Claudia contribute toward the total coverage? Round to the nearest tenth of a percent.
a) Graham's employer contributes $561.60 per year towards his coverage.
b) Claudia contributes 28.2% towards the total coverage cost.
What is percentage?
Percentage is a way of expressing a number as a fraction of 100. It is typically represented by the symbol "%", and is often used to express a change or a part of a whole.
a) Graham makes $62,800 per year, which is less than $65,000, so he pays $52 per month for individual coverage. His yearly contribution is 10% of the total cost, so his employer contributes 90% of the total cost. To find the total cost, we can multiply the monthly cost by 12: $52/month * 12 months/year = $624/year. So Graham's employer contributes $624 * 90% = $561.60 per year towards his coverage.
b) Claudia's annual salary is $75,400, which is at least $65,000, so she pays $122 per month for family coverage. Her employer contributes $1,052 per month towards her total coverage cost. To find the total cost, we can multiply the monthly cost by 12: $122/month * 12 months/year = $1,464/year. To find the percentage Claudia contributes, we divide her contribution by the total cost and multiply by 100: $1,464-$1,052 / $1,464 * 100 = 28.2%. So Claudia contributes 28.2% towards the total coverage cost.
Hence,
a) Graham's employer contributes $561.60 per year towards his coverage.
b) Claudia contributes 28.2% towards the total coverage cost.

Find the measure of the base angle in an isosceles triangle that has a base length of 6 and a leg length of 5. Round your answer to the nearest whole degree.
The base angle for the isosceles triangle is 53°.
What is an isosceles triangle?Any triangle with two sides that have the same length is said to be an isosceles triangle. If the two sides of a triangle are congruent, then the angle across from them must likewise be, according to the theorem that explains the isosceles triangle. As a result, the two angles of an isosceles triangle that are on opposite sides with equal numbers are equal in size.
Given base length = 6 and leg length = 5
draw a perpendicular to the base that divides the base into equal parts,
as shown in the image attached
let the base angle be Ф,
and using a cosine formula for the base angle
cosФ = base/hypotenuse
from construction base = 3 and hypotenuse = 5
cosФ = 3/5
Ф = cos⁻¹(3/5)
Ф = 53.13°
Ф = 53° (approx)

Answer: y=2x²+3x-5

Solve 4x²+6x-2y=10
1. subtract 4x² and 6x from both sides
(you do this to leave y by itself)
-2y=10-4x²-6x
2. divide -2 on both sides

To have $8,250 for a child’ education in 10 year, what amount hould a parent depoit in a aving account which earn 12 percent, compounded quarterly?
By applying the future values, the amount of money the parents should deposit to have $8,250 for a child’s education in 10 years is $2,529.09
A current asset's future value, abbreviated as FV, is the value that asset is expected to have at some point in the future, based on a projected rate of growth. The future value is essential for investors and financial planners because they use it to estimate how much money an investment made now will be worth in the future.
To find the future values, we can use this following formula:
FV = I x (1 + R)^T
Where:
I = investment amount
R = interest rate
T = number of years
In this case, we are given that:
Future values (FV) = $8,250
The periodic rate = 12% : 4 = 0.03 (compounded quarterly)
Number of period = 10 years x 4 = 40
Hence, the amount of money the parents should deposit to have $8,250 for a child’s education in 10 years is:
8,250 = I x (1 + 0.03)⁴⁰
I = 8,250: ((1 + 0.03)⁴⁰)

A front-end loader to load trucks with granular material that has a swell factor of 15%. If the loader has a heaped capacity of 10 cu. Yd. the total cycle time for the loader, if it can move 55 cu, is 16.2 hours( 55 cu. Yd. / 10 cu. Yd. (heaped capacity) * 15% (swell factor) * 48 min. /hr)
The total cycle time for a front-end loader to load trucks with granular material with a swell factor of 15% can be calculated by taking the total amount of in-bank material to be loaded and dividing it by the heaped capacity of the loader. This will give us the total number of cycles the loader must complete. Once we have this number, we must multiply it by the swell factor. This gives us the total number of heaped cycles the loader will have to complete.
Finally, we must multiply the total number of heaped cycles by the efficiency of the loader. Efficiency is the amount of time it takes for the loader to complete one heaped cycle. In this case, the total cycle time for the loader to load is 55 cu. Yd. Of in-bank material with a swell factor of 15% and a heaped capacity of 10 cu. Yd. Is 16.2 hours, assuming the loader has an efficiency of 48 min. /hr.

Does a square root graph have an inverse?.
A square root function is the inverse of a quadratic function. If a function f is the inverse of another function f1, then f is the inverse of f1.
The order of positive integers is preserved by the square function: greater numbers have larger squares. The square, then, is a monotonic function on the range [0, +]. Since negative integers have squares that are proportional to their absolute values, the square on [(,0] is a monotonically declining function.
The horizontal line test determines whether or not f has an inverse if any horizontal line crosses its graph more than once.

Since written methods for fractions are frequently employed, notably division by a fraction, it is useful to explain or defend these algorithms. The unitary method's formula is to get the value of one unit, multiply it by the number of units, and then divide the result by the desired value.
