M + T in standard form polynomial is -15r² + 2r + 8
How to represent polynomial in standard form?Polynomial in standard is when all its terms are arranged by decreasing order of degree.
Therefore,
M = - 8r²+ 11r - 6
T = -7r² - 9r + 14
M + T = - 8r²+ 11r - 6 + (-7r² - 9r + 14)
M + T = - 8r²+ 11r - 6 - 7r² - 9r + 14
combine like terms
M + T = - 8r² - 7r² + 11r - 9r - 6 + 14
In standard form, the polynomial is represented as follows;
M + T = -15r² + 2r + 8

Explanation
Since we have radicals in the denominator, we need to rationalize our expression.
To do it we just need to multiply both numerator and denominator by the conjugate of the denominator.
Remember that the conjugate of a binomial is the same binomial with the sing in between changed.
given that,
2/ (√13 + √11)
Now, we can simplify the denominator:
multiplying by (√13 - √11)
we get,
2 * (√13 - √11) / (√13 + √11)* (√13 - √11)
The only radical that we can simplify in the numerator is , which simplifies to:

Answer:
B) y = 4/5x - 2
Answer:
B
Step-by-step explanation:
First, we can find the slope of the graph.
The distance of x between the two points is 5, and the distance of y between the two points is 4.
The slope formula is (Increase in y)/(increase in x)
So the slope will be 4/5.
The y-intercept is (0,-2), so the number at the very end of the equation will be -2.
With all this in mind, we can be sure that our answer is B: y=4/5x-2

The cost of labor to manufacture a mountain bike is $90, and the cost of labor to manufacture a trail bike is $30. During a week in which the company has budgeted $1,600 for materials and $2,700 for labor, how many mountain bikes does the company plan to manufacture?
Answers
An equation is formed when two equal expressions. The company is planning to produce 25 mountain bikes and 15 trail bikes.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of mountain bikes produced by the company be x, while the number of trail bikes produced by the company is y.
The cost of materials for a mountain bike is $40, and the cost of materials for a trail bike is $40. Also, the budget of the company is $1,600. Therefore,
1600 = 40x + 40y
x + y = 40
y = 40-x
The cost of labour to manufacture a mountain bike is $90, and the cost of labour to manufacture a trail bike is $30. Also, the budget for labour is $2,700.
2700 = 90x + 30y
2700 = 90x + 30(40-x)
2700 = 90x + 1200 - 30x
1500 = 60x
x = 25
Substitute the value of x,
y = 40 - x
y = 15
Hence, the company is planning to produce 25 mountain bikes and 15 trail bikes.

Answer:
[tex]f^{-1}(x)=\left(\dfrac{x-7}{3}\right)^2[/tex]
Step-by-step explanation:
Given function:
[tex]f(x)=3\sqrt{x}+7[/tex]
To find the inverse of the function
Swap f(x) for y:
[tex]\implies y=3 \sqrt{x}+7[/tex]
Subtract 7 from both sides:
[tex]\implies y-7=3 \sqrt{x}+7-7[/tex]
[tex]\implies y-7=3\sqrt{x}[/tex]
Divide both sides by 3:
[tex]\implies \dfrac{3\sqrt{x}}{3}=\dfrac{y-7}{3}[/tex]
[tex]\implies \sqrt{x}=\dfrac{y-7}{3}[/tex]
Square both sides:
[tex]\implies \left(\sqrt{x}\right)^2=\left(\dfrac{y-7}{3}\right)^2[/tex]
[tex]\implies x=\left(\dfrac{y-7}{3}\right)^2[/tex]
Swap the x for [tex]f^{-1}(x)[/tex] and y for x:

Nadia says the hypotenuse of this right triangle has a length of 73 because the pythagorean theorem states that (28 45) squared = 73 squared. 3 squares are positioned to form a right triangle. the small square is labeled 28, medium square is 45, and large square is not labeled. which best describes nadia’s solution?
Answers
Both the options that Nadia gives are wrong about the length of hypotenuse.
Given length of hypotenuse is 73 and options which are :
1) Because the pythagoras theorem states that [tex]28^{2} +45^{2}[/tex] squared = 73 squared.
2) 3 squares are positioned to form a right triangle.
We have to choose the correct option which shows the calculation of length of hypotenuse.
Pythagoras theorem says that in a right angled triangle the square of hypotenuse of triangle is equal to sum of the square of base and square of perpendicular.
[tex]H^{2} =P^{2} +B^{2}[/tex]
First option says that [tex]28^{2} +45^{2} =73^{2}[/tex]
784+2025=5329
2809≠5329
so it is wrong.
Second option says that the length of hypotenuse is the sum of three squares but we have seen that the square of the length of hypotenuse is equal to sum of two square one is the square of base and the square of perpendicular.
Hence both the options are incorrect about the length of hypotenuse.

Mark Achin's economic order quantity in units is D. 120 units.
What is economic order quantity?The economic order quantity (EOQ) is the optimal order quantity that minimizes the total costs (ordering, receiving, and holding inventory).
The formula for the economic order quantity is the square root of [2(setup costs)(demand rate)] / holding costs.
Data and Calculations:Annual demand = 3,600
Cost price per unit = $200
Ordering cost = $40
Holding cost per unit = $20
Working days per year = 360
Lead time = 5 days
Economic order quantity (EOQ) = square root of: [2(setup costs)(demand rate)] / holding costs.
= square root of (2 x $40 x 3,600)/$20
