Write the standard form of an equation with p=3 sqrt2, theta= 135°​
Arlecino [84]

Answer:

x - y + 6 = 0

Step-by-step explanation:

In normal form of a straight line, the equation is given by  

x\cos \theta + y\sin \theta = p

where p is the perpendicular distance of the line from the origin and \theta is the angle between the perpendicular line and the positive direction of the x-axis.

Here, in our case p = 3\sqrt{2} and \theta = 135 Degree,

Therefore, the normal form of the straight line equation is  

x \cos 135 + y \sin 135 = 3\sqrt{2}

⇒ x \cos (180 - 45) + y \sin (180 - 45) = 3\sqrt{2}

⇒ - x \cos 45 + y \sin 45 = 3\sqrt{2} {Since, Cos (180 - Ф) = - Cos Ф and Sin (180 - Ф) = Sin Ф}

⇒- \frac{x}{\sqrt{2}} + \frac{y}{\sqrt{2}} = 3\sqrt{2}

⇒ - x + y = 3√2 × √2 = 6

⇒ x - y + 6 = 0  

So, the standard form of the equation is x - y + 6 = 0. (Answer)

Select from the matches below to correctly complete the statements. I'll give brainliest to someone with correct answer!
Aneli [31]

Answer:

<h3>The correct matches as follows :</h3>

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

3) The product of a linear monomial and a linear binomial - Quadratic binomial

Step-by-step explanation:

The correct matches as follows :

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

<h3> Monomial is a linear expression having only term with degree 1 (variable)</h3>
  • For Example : Let x and y be two monomials which is linear
  • If we product the two linear monomials we get
  • x\times x=x^2 which is a quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

<h3>For example : Let x^2 be the Quadratic monomial has one term with degree 2 and x^2+2x+3 be the quadratic trinomial ( has 3 terms with degree) </h3>
  • If we product the quadratic monomial and quadratic trinomial we have
  • x^2\times (x^2+2x+3)=x^2(x^2)+x^2(2x)+x^2(3)
  • =x^4+2x^3+3x^2
  • Therefore x^2(x^2+2x+3)=x^4+2x^3+3x^2 which is a quartic trinomial has degree 4 with three terms

3) The product of a linear monomial and a linear binomial - Quadratic binomial

<h3>For example : Let x be the linear monomial and x^2+5 be the linear binomial has two terms with degree 1</h3>
  • If we product the linear monomial and quadratic binomial we get
  • x\times (x+5)=x(x)+x(5)
  • =x^2+5x
  • Therefore x\times (x+5)=x^2+5x which is a quadratic binomial with degree 2

Pleas help me answer this. Question 2 please.
tamaranim1 [39]

Answer: A

We could solve it but it's easier to just check the given solutions.

A. (7,1)

2y + 5 = 2(1)+5 = 7 = x, good

x/3-y = 7/3 - 1 = 4/3, good

B. (-3,8)

2y + 5 = 2(8)+5 = 21 not x=-3, doesn't check

C. Can't be true because we found a solution

D.  Infinitely many solutions not true because the lines have different slopes

Keith Rollag (2007) noticed that coworkers evaluate and treat "new" employees differently from other staff members. He was inter
gayaneshka [121]

Answer:

a) Real range of employees hired by each organization surveyed = 56

b) The cumulative percent of "new" employees with the lowest tenure =        30%

Step-by-step explanation:

a) Note: To get the real range of employees hired by each organization, you would do a head count from 34 to 89 employees. This means that this can be done mathematically by finding the difference between 34 and 89 and add the 1 to ensure that "34" is included.

Real range of employees hired by each organization surveyed = (89 - 34) + 1

Real range of employees hired by each organization surveyed = 56

b) It is clearly stated in the question that  the "new" employee status was mostly reserved for the 30% of employees in the organization with the lowest tenure.

Therefore, the cumulative percent of "new" employees with the lowest tenure = 30%
